In today’s episode, Ashley asks, How can I make the case for AI and marketing? Well, here’s the this is a challenging question, here’s why it’s challenging.

That assumes that you have a problem for which AI is the best solution.

Right? And that means you need to understand what things AI is really good at, and what things AI is not good at.

Right? Fundamentally, artificial intelligence is good at two types of problems, right classification problems, and regression problems for the most part.

Now, there’s, there’s some flexibility in that, but those are the biggest, broadest categories.

If you got a bunch of stuff that you need to categorize and classify.

AI is actually really good at that.

particularly things like images, audio, video, text.

Classification, is a particularly strong area for AI to do its work.

And regression, or which leads to prediction AI is reasonably good at things like that forecasting, trying to understand what contributes to an outcome.

What are the drivers of an outcome? AI is pretty good at that.

So the question is, do you have a problem for which AI would be an appropriate solution? There are a whole bunch of problems where AI is not be answer.

For example, in some there’s some kinds of forecasting where simpler statistical methods like auto regressive integrated moving averages still deliver best in class performance, better than neural networks better than, you know, really complex regression algorithms and machine learning powered regression algorithms something sometimes, and ARIMA result is perfectly fine.

So a major challenge for somebody who is not a data scientist is to understand which problems are suited for AI and which are not.

If you’ve got a problem for which there is a lot of data, both for the problem itself, and for past solutions than AI is probably a good candidate, right? Say you’ve got a million pages of text, and that that have good examples and bad examples of writing.

And you got 10,000 new pages, you need to assess are these good or bad.

With that much data, AI is actually a really good solution.

Because there’s enough information to train a model, which is fancy for have AI write software for itself, that it can successfully build that model, and then run it against your production data.

AI is also really good at in general data where there are clear patterns, and clear repetition that requires scale, right.

One of the big challenges with AI problems with just throwing a at a problem is that there may not be enough data to create that model, right? If you’re trying to say build a model to write great corporate blog posts for your company, and you’ve only got like 200 blog posts, you’re gonna have a hard time, that’s not impossible, you can take an existing model and fine tune it.

But for the most part, that’s not enough information to really help it it build a good robust learning data set a training data set for to generate the outcomes you want.

On the other hand, if you’re a company that you’ve got 2 million blog posts, then you’re talking, right, and now you’ve got enough to cook with, it’s kind of like, there’s a minimum amount of ingredients you need for a recipe to work, right.

There’s some ingredients, some recipes, where if you don’t have a sufficient number of ingredients, it never reaches critical mass and it doesn’t work.

Like you can’t really bake a loaf of bread with a quarter teaspoon of flour.

I mean, if you scaled down all the ingredients, there’s just not enough mass there for the recipe to work properly.

You know, the same is true for like a model cars and stuff below a certain scale size.

An internal combustion engine simply doesn’t work.

Well if it’s like this big.

Right? And that’s the challenge you face with with artificial intelligence.

So big data in means that you’ve got a good case for AI.

Christopher Penn 4:43

If you find a problem has no repetition, it’s a bad candidate for AI.

Right.

So this is one of the reasons why we all often say AI will take tasks and not jobs because your job from day to day is wildly different.

Right? different meetings, different participants, different activities, different kinds of lunch you eat, there’s a whole bunch of these random variables.

But within your job is a series of tasks.

And sometimes those tasks are highly repetitive.

And if it’s highly repetitive, then there’s an opportunity potentially to bring in some, some machine learning to pick up that individual task and automate it.

When I am putting together my weekly newsletter, the process is exactly the same week after week and automated a substantial part of it because it’s so repetitive.

However, there’s still a decent chunk of it that is manual that is human because that part is wildly variable.

Things I feel like writing about that week, vary wildly from week to week.

So do you have a case to fit to make for AI? If you have a lot of data, and it’s highly repetitive? One of the things people are thinking about is does AI or machine learning? Does? Is there a case to be made based on cost savings.

And this is tricky, because it depends on the task.

It depends on the task.

And it depends on the complexity, and all the stuff that we’ve just mentioned.

There are definitely things where it doesn’t pay for a human to do it.

So like curating content for social feeds, right, that is a machine based task, for sure.

It’s relatively low value, highly repetitive, big data.

And solving for it is worthwhile, right, because you can take some, you know, two hours out of somebody’s calendar each week, and turn that into five minutes, that’s two hours back that you get that you can do something else with that time.

On the other hand, there are some tasks where the creation of the model and the maintenance of the model would be so vast, that you’d be better off doing it manually, right? Like shooting your video each week, if I were tried to have a machine do this entire video from beginning to end, the enormity of that task and the high variability of it would be so difficult that it would take me years to make it happen.

And it wouldn’t be worth the return on investment would be a negative.

So that’s a major part of this question is, when you’re making a case for AI, can you make a case for a positive return on investment for its application? This is one of the reasons why Artificial intelligence has not been widely adopted by many businesses.

Because in a lot of cases, people are treating it as this magic wand.

And as a result, they’re not doing a simple cost benefit analysis and saying actually, this is a problem that isn’t worth solving with with machine learning.

Better off solving with basic statistics or an Excel spreadsheet or just doing it manually.

Yeah, real simple example I influencer identification.

There’s a whole bunch of different ways to do it.

But if you’re validating the feeds of influencers, and you do it once a year, it’s probably not worth automating.

If you’re doing every day, then it’s worth automating.

So that would be my suggestion.

But how do you make the case for AI figure out if you’ve got an AI problem to begin with before anything else? Thanks for asking.

We’ll talk to you soon.

Christopher Penn 0:13

In today’s episode, Fabrizo asks, Can you make the intro shorter? Yes, the intro is now 60% shorter from 30 seconds down to 12.

Now, Maureen asks, why do people use machine learning and AI these two terms interchangeably? Well, the reason is because honestly, it’s because I think most people don’t have a good sense of what either term means.

And so they just kind of mix and match.

To be clear.

Artificial Intelligence is a an umbrella term that is specific to teaching machines to develop intelligence skills that we have naturally.

So if you are watching this video, and you can distinguish me from the background here, right, you’re using vision, if you’re hearing the audio to this video, and that’s not just noise, you’re able to distinguish things like sounds, different sounds you’re using hearing, right? If those sounds get turned into words, you’re using what’s called language processing.

All of these are intelligence skills.

And when we teach computers to do these things with artificial intelligence, right, it’s an intelligence skills that we’re teaching to a machine, rather than being something that’s natural, done by humans or other animals to obviously, things like parrots can certainly learn to repeat words and such.

machine learning is a subset of artificial intelligence, it’s part of AI, but it is not all of AI.

And machine learning, specifically refers to giving data to machines from which they can write their own software, right, they can build their own code, based on the information they’re given, and a pre defined set of tools and algorithms to build their own code.

All machine learning is AI, but not all AI is machine learning.

Right? So it is a subset.

Why people use these two interchangeably, partly, partly is a marketing reason.

In some ways, artificial intelligence has been a buzzword now for about 10 years.

And as such, has sort of lost its luster.

Understandably, so.

There have been many, many AI projects that have gotten off the ground that didn’t really go anywhere.

And there have been a number of movies and TV shows and things where consumers and the general population were introduced the concept of AI and it created these mistaken perceptions about what machines are capable of people think of, you know, the Terminator, and killer robots and Star Trek.

And all of these different types of artificial intelligence that are more properly artificial general intelligence, which means machines that are essentially sentient, no such things exist as of this recording, and so for distinguishing that sort of consumerization of the AI term, a lot of folks have said, Okay, well, maybe we should focus in specifically on the machine learning part.

Given data, we’re teaching machines to do other intelligence tasks and create their own software.

Most of the artificial intelligence that you interact with on a day to day basis is machine learning.

From recommendations that you get from Google Analytics, from recommendations you get on Amazon when you’re shopping and says You might also like these three other things that are somewhat related to what’s in your cart, every time you fire up Netflix, and it suggests another series, or you fire up Spotify, it says, Consider adding these songs to your playlist.

All of that is machine learning.

There’s yet another distinction that people like to make the differences between classical machine learning and deep learning.

Deep learning is when machines are not only writing their own software, but they’re also choosing their own algorithms based on all kinds of data inputs and these neural networks.

The closest analogy I think you could easily make as if machine learning is a chef with a lot of very expensive, fancy machines that do you know 90% of the prep work.

Deep learning really is a kitchen that almost completely runs itself, right? There’s there’s very little to no human intervention a lot A lot of the time,

Christopher Penn 5:02

the challenge and the reason why you would pick one of the over the other is based on the amount of data you have.

Deep learning requires a lot of data, we’re talking millions of records, millions of samples from which the machine can create a neural network.

Oftentimes, especially in marketing, we don’t have millions of examples to train on.

So when we have something, for example, like the GPT, Neo X, natural language generation models, that’s trained on 800 terabytes of text, right, the entirety of Wikipedia, the entirety of Google Books, there’s tons of information to work from when you’re trying to build a model for your ideal customers.

But you don’t have 10s of millions of ideal customers, right? If you’re a B2B company, you probably have like five ideal customers, right? That the CMOS of the Fortune 10 Are your ideal customers.

And so those cases where classical machine learning makes a lot more different, much more of a difference is much more effective than deep learning.

So which term should you use depends on which application if you’re talking about the overall teaching of tasks that are currently done by humans, vision, listening, language, etc.

AI is a perfectly fine term to use.

If you are talking about the feeding of data to machines to build their own models, you’re talking about machine learning.

If you’re talking about building neural networks, out of very large data sets, you’re talking about deep learning.

And there’s a few other more specialized terms in there, but those are probably not as well recognized outside of the AI field.

So don’t worry too much about them right now.

The last caution I will offer is Buyer beware.

A lot of companies will say that they use artificial intelligence or machine learning and in fact are not.

In 2018.

The Financial Times did a survey of 100 companies that were claiming to use AI and did some substantial background investigation found that 35% of them were just outright lying.

They had offshore outsourced humans doing the work instead.

So just because something is using AI or machine learning a doesn’t mean it actually is and be doesn’t mean that it’s it’s any good, right? I can use machine learning to overcomplicate nearly any problem.

It doesn’t make the solution better.

It just changes what technologies are in the solution.

So really good question.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

Alright, let’s get going here we have Max asking, Do you think that it is possible at AI, artificial intelligence becomes more advanced to the point where an algorithm or deep learning can develop its own conscious thoughts? Today? No.

In the near future? No.

The challenge with consciousness as we understand it right now, is that it is a massive interaction of a computer network, right? A massive neural network.

What is in your pocket, right? These devices as smart as they are as connected as they are? This is really, you know, I think this phone has like, eight cores, eight processors or whatever, something like that.

Now, your your laptop like I’ve got a brand new MacBook has got 32 cores.

Your brain even though it is electrochemical, which is slower than than silicon, then then these things is trillions of interconnected processors.

And it is that network that gives rise to consciousness.

These devices, this hardware doesn’t have the ability to do that, right? There’s simply not enough, there’s no way to cram that many processors into a compact enough space where consciousness can emerge.

Now, I say that that’s not enough time soon, but it doesn’t mean it’s impossible.

One of the limitations of these things that our brains don’t have is because of the way things are networked together.

Silicon processors can’t, they have no, they have no middle states, right, they’re either on or off zero or one.

And our brains don’t work like that.

We do have firing thresholds for neurons, but for the most part, we’re less zero to one, there’s there’s a lot of variants between zero and one.

Now there is a form of computing that is getting towards that.

And that is called quantum computing.

Quantum computing allows for minus one to positive one and all the values in between, for a, a computation to occur in a processor.

And we’re still only at like 130 Quantum cores.

So we’ve got a long way to go, before we get to the trillions of cores needed to replicate what’s in here.

But you can see a path forward for that, you can see a path forward where quantum computing will eventually give us the ability to have emergent consciousness from machines.

Now what that looks like and when that happens, we have no idea it could be within my natural lifetime, it might be longer than that.

A lot of it is contingent on physics, on the constraints that physics imposes on these types of computers.

But it is possible and when that happens, we are going to have a bit of a reckoning as a society to figure out what all constitutes consciousness what all what all do we have to do about ethics and things when machines can actually think and feel for themselves? They cannot today, but they could at some point.

So really interesting question Max.

Thanks for for submitting Matt.

Paul asks, looking back on the way you learned about AI, is there anything you wish you would have figured out first? Yes.

So machine learning and data science really are a blend of, of four different areas, right.

So there’s the business side, it’s the business problem, the the business strategy you’re trying to solve, there is the data engineering side, which is handling data.

Storage, being able to, to retrieve and rank an index data this that you have stored, there is the coding side, where you have to be able to read and write code in a language like R or Python, which would allow you to be effective.

And then there’s the mathematics, you know, statistics and probability side, knowing the advanced mathematics, so that you not only know what the machines are doing, but you know why, you know why certain algorithms make for better or worse fit, certain techniques make it for better or worse fit.

And when I look back, I’m self taught on a lot of this stuff.

So I have a lot of gaps.

In my knowledge, particularly on the mathematics side, I can patch gaps pretty easily on the code side, I know the business side.

I know the data engineering side fairly well actually, because I have an IT background, but my my weak spot, my blind spot really is on the mathematics side, particularly once you get into stuff like linear algebra and things like that.

Higher level mathematics, that’s when I feel the biggest gaps.

And so from a professional development perspective, certainly, that’s something I wish I had known, more of going into this.

And certainly something that I’m spending a lot of time nowadays, trying to remediate so that it’s not as big a weakness, right? It’s not as big of a gap.

do a self assessment in those four areas and figure out which area are you weakest in? Which area are you strongest in, and then try to patch those weak spots, particularly if you’re still in school.

Definitely take the time to patch those weak spots, take an extra course in something that you know you’re not good at.

So that it’s less of a vulnerability or added also it’s at the very least, you’re not going to be paying a lot of money to an institution to later on to reteach you something you have to learn the first time around.

Good question.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

Okay, let’s get started.

The Kelsey asks, If you were to start writing your book now, this is AI for marketers, instead of when you wrote it, what would you change and why? Well, the challenge with writing any technology book is that the moment you hit publish, it’s out of date.

And that’s doubly so for a fast moving field like artificial intelligence where you are creating a something to be read and consumed.

While the technology it’s about is racing ahead.

When I finished the third edition of this thing, I had some stuff on language models and image generation.

But so much has happened in just a year.

That it’s you it’s out of date enough that there are possibilities now that are excluded in that book, right? I don’t mind having something out of date, if there are percentage points, improvements in performance, or, you know, refined capabilities.

But the technology pretty much does the same thing.

But what’s happened in the last year is we’ve had leaps of functionality change in artificial intelligence, the ability for us to generate imagery, from a prompt from, from a series of text prompts, is one of the most frequent examples, recent examples from Nvidia came out with that and go again to and then a bunch of consumer apps for your smartphone have come out as well.

That’s a game changer for functionality, the GPT J 6b Library, the natural language generation library, again, huge model that does autocomplete of like entire documents.

That’s a game changer because it reduces the burden for us as humans to generate stuff like you know, a press release, right, you can write a press release better than we can, it’s still not great because press releases in general are not great, but it is different.

So I would obviously change those things to was the process of writing the book.

One of the things that I think would be interesting at some point is to do a book that’s more collaborative.

Every single one of my books that I’ve written so far, really has been my point of view on stuff without any outside voices.

I think it may be time at some point.

Maybe it’s the the new thing I’m working on right now, where bring in some additional voices for some variety.

So good question.

Thanks for asking.

What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

Alright, Lane asks, although AI can help solve various issues we face today can also create discriminatory algorithms.

What solutions do you post to solve the problems AI causes? Well, here’s the thing.

Everything that happens with machines comes from human data, right? There’s nothing that is outside of our existence.

And so the problems that we see with bias in AI and machine learning come from us, right? The humans, we are the problem.

And the problem occurs, the problem can occur in a variety of areas.

It can be the people we’ve hired, right, if people, the people we’ve hired have biases, it doesn’t matter what else you do, you’re going to have problems, right? So that’s a huge part, it’s an overlooked part of machine learning AI is what are the biases.

Remember, there’s two kinds of bias, right, there is human bias, you know, maybe you don’t like people with red hair.

Maybe you don’t like people of a certain race, or religion or whatever.

Those are human biases.

And then there’s statistical biases, which is just where a sample is not representative of the population, the sample is drawn from.

The people that you hire, have got to understand both of those, and know to look for both of those in the data that they’re working with.

Right? So if you’re looking at, say, some survey data that you’ve done before, in some market research, and you don’t know how to check to see whether the sample is representative or not, you could have some really serious problems.

So people is first second overall strategy, is there a bias inherent in your strategy? I remember a number of years ago, my wife worked at a market research firm.

And the they were the epitome of what not to do in market research.

They were a conservative sort of Think Tank.

And people would come to them saying, I need research that backs up this point of view, by anybody who knows anything about market research and statistics knows that that’s pretty much the worst way that you can do market research other than just making things up completely.

And so the strategy can have biases in it.

The data can have biases, and there are mitigation tools for that, for toolkits, for example, like IBM’s AI fairness, 360 toolkit that can look at your data and say, Hey, these look like protected classes like gender, or religion, or ethnicity.

And it looks like these are non representative values in here like, hey, for some reason, this entire dataset, which has a gender field, is like 98% men and 2% women, you might have a problem in your data.

So what these tools can do to identify biases in the data set their biases that can creep in, in the choice of algorithms.

And again, more advanced tools like IBM Watson Studio have some some protections built in to avoid those problems, or mitigate them or at least identify that there’s a problem.

And then you get bias in the model as it drifts, right.

So you publish a model, it’s in production.

And then over time, as it gets new data and learns from new data, it becomes less and less accurate, it drifts.

It also may have biases in it that cause drift.

The most famous example, this was back in 2016, Microsoft Tei.

They focus on Microsoft created a twitter bot.

And it learned from the tweets people sent it and it became a racist porn bot in less than 24 hours.

There were no protections on model drift.

And so each of these areas where bias occurs or can occur has some level of protection you can build into it, but you have to know to think about it to look forward to ask questions about it.

You’ve got to have a way to identify it in the hiring process.

You’ve got to have a way to for a safe way for people to raise concerns in the workplace, right if they see a strategy that’s clearly biased in some way that’s That’s incorrect.

There’s got to be a safe way for people to elevate their concerns and and have those concerns answered.

Again, using tools like fairness 360 for the data, using tools like Watson Studio for the algorithms and the deployment.

And monitoring your models for drift will help you reduce the potential for or the impact of bias and the thing is we have to, we have to be on the lookout for it.

And we have to accept that it is going to occur and remediate it.

And one of the big challenges that companies will run into is they will fight, tooth and nail sometimes to say that they are not biased.

Like it’s not possible.

Well, have you checked, right? Do you know? Have you proven that bias does or does not exist? In any of the systems and if you can’t, you’ve got a problem.

Treat datasets, models, algorithms and, and production systems.

guilty until proven innocent.

When it comes to bias.

Assume that there’s bias until you prove that there isn’t.

If you want to have the best possible outcomes really good question.

Stop Using Artificial Intelligence For Human Intelligence Problems
One of the most challenging concepts to understand in machine learning and AI is machines and humans don’t think in the same way. We make the general assumption that artificial intelligence and natural intelligence function in the same way, that machines are just faster, less expensive versions of ourselves.

In reality, our two intelligences are very, very different – and our understanding of those differences will make it easier or harder to successfully implement AI.

Human intelligence is based on massive parallel processing. Your brain is filled with trillions of brain cells, and all joking aside, is one of the most powerful computers in existence. But the way our brains compute is fundamentally different than our silicon offspring. Our brains actually process very slowly for the most part; the nerves, chemicals, and electrical impulses in our brains individually transmit very slowly but do so in vast quantities.

Silicon intelligence – machine intelligence – is today based on extremely fast serial processing. The largest computers have millions of processors available to them; your average laptop today has 4 or 8 processors. Those processors process information extremely quickly in binary format, turning everything into zeroes and ones.

Imagine you have a factory, and that factory makes widgets. There are two ways to increase productivity at the factory. You can have a few workers who are extremely fast at their jobs, or you can have thousands of workers who are individually slow but extremely fast as a collective. That’s the difference between machine and human processing capabilities.

Here’s why this matters: the kinds of problems you can solve with each type of intelligence are based on what that intelligence is good at. Computers? They can do math extremely fast, much faster than we can, because they have a few brain cells (comparatively) that are very, very fast. Math, statistics, probability, all kinds of computation – they are faster than we ever will be. But tasks that require massive parallel processing? Computers do those very slowly by comparison – and those are tasks like language, vision, hearing, etc.

In other words, our brains are best equipped to deal with the inputs they receive from our sensory apparatus – taste, touch, smell, sound, sight. That’s not news to anyone, but when we look at the kinds of problems we try to solve with AI, the closer a problem is to a problem human intelligence excels at, the more challenging the problem will be for AI. Vision, for example, requires MASSIVE parallel processing to be able to take in all the data that makes up sight, process it, and derive meaning from it – but our brains do it easily because we devote substantial numbers of brain cells to the task.

Conversely, the closer a problem is to what silicon intelligence excels at – computation – the more challenging the problem will be for a human. You probably can’t do fourth order derivative equations or multiple regression analysis in your head for complex problems, but machines can. Those kinds of problems are easy to distill down into zeroes and ones and crunch at insane speeds.

Which means, as you start thinking about the implementation of AI, break down your business challenges into components and then see which category each of those components falls into. For example, if you want to boost sales, you have an entire pipeline of components – how sales reps talk to customers. How your marketing is received by customers. How your lead scoring and CRM are managed. How you forecast demand.

Some of those components are well-suited to machines and shouldn’t be left in the hands of humans.

Some of those components are well-suited to humans and shouldn’t be left in the hands of machines.

This means that any company, product, or service which promises “all-inclusive” AI-powered software that will solve all your problems and be magic… won’t. By very definition, it’s going to be bad at some things, and good at others.

If you want to see fast wins from your AI efforts, focus on those tasks that computer intelligence excels at, and start your implementation there first – then move up to the tasks that computers find harder to do well.

How Much Data Do You Need For Data Science and AI?
How much data do you need to effectively do data science and machine learning?

The answer to this question depends on what it is you’re trying to do. Are you doing a simple analysis, some exploration to see what you might learn? Are you trying to build a model – a piece of software written by machines – to put into production? The answer depends entirely on the outcome you’re after.

Here’s an analogy. Suppose you’re going to bake cake. What quantities of ingredients do you need?

Well, how many cakes are you going to bake, and how large are they? There is a minimum limit to quantities just for the basic chemistry of baking a cake to happen at all, but there are cakes you can make that are disappointingly small yet are still cakes.

Are you baking a round cake? A sheet cake? Ten sheet cakes? How quickly do you need them?

You start to get the idea, right? If you need to bake 100 cakes in 24 hours, you need a much bigger oven, probably a much bigger mixer, perhaps an extra staff member, and a whole lot of flour, sugar, milk, eggs, and baking powder than if you’re baking a single cake.

The same is true of data science and AI. To do a simple exploratory analysis on a few Tiktok videos requires relatively little data. To build a model for the purposes of analyzing and reverse-engineering Tiktok’s algorithm requires tens of thousands of videos’ data, possibly more.

Some techniques, for example, can use as few as a handful of records. You can do linear regression technically with only three records, that’s the bare minimum amount you need for a simple linear regression to function. Other techniques like neural networks can require tens of thousands of records just to put together a functional model. That’s why it takes some experience in data science and machine learning to know what techniques, what recipes fit not only the outcome you have in mind, but also what ingredients and tools you have on hand.

There’s no firm benchmark about how much data you need, just as there’s no firm benchmark about how much flour you need for a cake. What is necessary is understanding the outputs you’re trying to create and then determining if you have the necessary ingredients for that output.

Happy baking!

What’s the Value of Anecdotal Evidence?
In the world of data and analytics, anecdotal evidence is often (and correctly) demonized. Why? People in general and marketers in specific mistake anecdotal evidence for quantitative proof, for statistically representative, reliable, and repeatable evidence.

Anecdotal evidence is none of those things. It’s one person’s experience, so it’s not representative. Depending on that individual’s perspective and biases, it may not be reliable. Its very nature as an anecdote means that collecting similar information under similar circumstances is not repeatable.

Even anecdotal evidence in aggregate is still not reliable. In aggregate, anecdotes do not necessarily have the statistical rigor to be proof of anything, especially if there was any kind of bias in the collection of the anecdotes.

So, should we just toss away all our anecdotal evidence? Of course not.

The Value of Anecdotal Evidence

Let’s be clear what anecdotal evidence is. It’s a story, literally meaning “something unpublished” from ancient Greek. Anecdotal evidence is qualitative data. It doesn’t measure anything, but it does describe one person’s experience with something, their story.

And in every story lies the potential for rich data to investigate, for questions to ask.

For example, let’s say we’re working on market research for the next great cup of coffee at our coffee shop. While sitting in the shop with a cup of coffee, the guy next to us makes an offhand remark about how he’ll never drink kopi luwak even though it’s one of those trendy coffee things. If we’d never heard of kopi luwak, this anecdote, this piece of qualitative data, is a new starting point for us to investigate. Perhaps our coffee shop companion might never drink kopi luwak, but that doesn’t mean our other customers wouldn’t.

Every time we commission some interviews, some focus groups, read our customer service inboxes, or listen and watch our customers as they go about their lives, we’re collecting qualitative data. We’re collecting stories, anecdotes – and inside those stories may be critical details we won’t and can’t collect from quantitative data.

Imagine for a moment how much data you’d need to collect and process to see how a million customers use your products. You could not reasonably and rationally collect that much information, have a million employees shadow customers throughout their days. Could you reasonably do that with ten customers? Yes – and those observations could be very valuable.

Suppose you make an LED desk lamp. What assumptions would you have made in its design? You would have assumed people kept it on their desks and used it to light the desk and read with. Now suppose you visited my house and you saw this:

I’m using these desk lamps, inverted, as indirect light for an entire room. This is a harmless but unintended use of these lamps – it’s an observation, an anecdote. Now suppose you went to 10 customers’ homes and in 4 of them, you saw similar uses. Would this change how you think of your product? It should. It should make you ask, just how many of our customers use our product in a manner different than we designed it for? If enough did, you could offer different models and variations of the product that would fulfill these new, unintended uses even better, increasing the sales of the product.

Without these anecdotes, without this qualitative information, you would not have known this. You would not have thought to ask this, but with just a handful of customer stories, you have a starting point to ask better questions and collect more statistically relevant data.

Supercharging Qualitative Data with AI

But here’s where things get interesting — and where the game is changing dramatically. What if you could process not just 10 customer stories, but 10,000? What if you could find patterns in qualitative data at scale? Enter generative AI and large language models (LLMs).

Think about this for a second: Every day, your company probably collects thousands of pieces of qualitative data:
– Customer service chat logs
– Social media mentions
– Support tickets
– Survey open-ended responses
– Sales call transcripts

And honestly? Most of that gold mine of information just sits there. Why? Because traditionally, analyzing qualitative data meant having humans read through every single response. (I’ve done this. It’s about as fun as it sounds.)

But here’s where AI changes everything.

Let’s break down how you can use LLMs to make sense of qualitative data:
1. Data Collection and Preparation
– Gather all your unstructured text data
– Clean it up (remove personally identifiable information)
– Format it consistently
1. Initial Analysis
– Feed it into an LLM with clear prompts
– Ask for theme identification
– Look for unexpected patterns
1. Pattern Recognition
– Have the AI categorize mentions by topic
– Identify sentiment patterns
– Flag unusual or unexpected uses of your product

Here’s a real example I tried recently: I took 1,000 customer service chats and asked an LLM to identify patterns in how customers described their problems. The AI found that customers were using specific product features in ways we never anticipated — just like those inverted desk lamps, but at scale.

But — and this is crucial — the AI isn’t giving us quantitative data. It’s helping us process qualitative data more efficiently and spot patterns we might miss. It’s like having a really smart assistant who can read through everything and say “Hey, you might want to look at this…”

Some practical ways to use this approach:
- Feed customer reviews into an LLM and ask it to identify common use cases you haven’t documented
- Analyze support tickets to find creative ways customers are working around product limitations
- Process social media mentions to spot emerging trends in how people talk about your brand
The key thing to understand? This isn’t about turning qualitative data into quantitative data — it’s about making qualitative data more actionable at scale.

From Insights to Action

The value of anecdotal evidence is to help us ask better questions. Don’t misuse it or mistake it to be quantitative data, but don’t throw it away, either. Use it to explore, to widen your perspectives, and ask better questions to earn better answers. And now, with AI tools at our disposal, we can do this at a scale that wasn’t possible before.

What’s next? Start small:
1. Pick one source of qualitative data you already have
2. Use an LLM to analyze it for patterns
3. Take those patterns and form hypotheses
4. Test those hypotheses with proper quantitative research

Remember: The goal isn’t to replace quantitative data — it’s to find better questions to ask when we do our quantitative research. And with AI, we can now find those questions in places we never could before.

(And yes, I’m still using those desk lamps as indirect lighting. Sometimes the best insights come from the most unexpected places…)

Why AI Will Not Create Great Content Any Time Soon
I am bullish on AI creating content at scale.

I am bearish on AI creating GREAT content at scale – or at all.

Why? It comes down to limits of training data, fundamentally.

All machine learning models, from the most basic to the most sophisticated, need something to learn from. In the case of language generation – automated creation of content – they need tons of examples to learn from.

And therein lies the problem.

Before we go farther, let’s define great content as content that’s well-written with a unique point of view and a distinct voice. That part is important.

Content Quality in the World

When it comes to publicly available content, there are two potential distributions, a power law distribution and a normal distribution.

A power law distribution looks like this:

This is also known as an 80/20 rule or a 95/5 rule; fundamentally, the amount of poor quality content dwarfs everything else. The amount of great quality content is on the right hand side – and it’s very small.

A normal distribution looks like this:

In this case, it says there’s a small pool of absolutely terrible content, a massive amount of mediocre content, and a small pool of absolutely great content.

Whichever distribution we think represents reality, there’s very little great content compared to everything else – which means machines have very little great content to learn from.

And if there’s an insufficient amount to learn from, then the machines will not be able to synthesize great new content. They will be able to synthesize mediocre content or poor content.

How Much Content to Train?

How much content are we talking about in order to train a natural language model? The Pile, an 800 GB dataset created by Eleuther.ai, is a training dataset composed of 22 libraries:

The largest item in The Pile is the CC, the Common Crawl, derived from the Wayback Machine and Archive.org. That means it’s ingesting a huge amount of web text from all over the web – and of substantially varying quality. OpenWebText2, according to the documentation, is another scraping of web content based on Reddit upvotes.

All this indicates the level of quality of the training data. The folks who assembled this training dataset, like the other major natural language models, have done their best to filter out the bottom of the barrel, the absolute garbage that would do more harm to a natural language model than good. So we can be fairly confident in a normal distribution in terms of content quality; after all, YouTube subtitles, US patents, and medical papers are important documents but not exactly riveting reading most of the time.

What isn’t obvious from the table above is just how little data we have for a specific example. The Common Crawl is 227 GB of data, with an average document size of 4 KB. What that works out to is a dataset of 56.7 MILLION pages. That’s how many web pages are needed in just a portion of the training set.

The overall dataset is 825.18 GB, with an average document size of 5.91 KB. That’s 139 MILLION pages of text. That’s what is needed to construct a language model.

Now, let’s say for giggles that you think your website is the bee’s knees, that your content is A+ content. Let’s use Social Media Examiner, a well-regarded blog, as an example. How many pages are on this site? About 62,000 per the AHREFS SEO tool. When you think about it, that’s a tiny amount of text. Even the Reddit-filtered OpenWebText2 portion of the pile is 16 million pages.

In terms of a unique voice, let’s use this blog. I’ve been blogging here consistently since 2007. How many pages of content have I managed in that time? 8,954. That’s not a ton of content in the big picture compared to what is used to train machine learning models.

Which means that natural language models will inherently be biased towards creating mediocre content, content that’s readable and coherent, but not compelling or unique, because that’s what the vast majority of the language is that they are trained on.

An Example

Let’s illustrate the limits of language models trained on a diet of mostly mediocre data. First, let’s take a mediocre use case – writing a press release. I’ll feed the GPT-J-6B natural language generation model the following text from a press release:

NEW YORK–(BUSINESS WIRE)–Today, Effectv, the advertising sales division of Comcast Cable, released the latest edition of its TV Viewership Report. The report explores viewership trends for the first half of 2021 based on Comcast aggregate household viewership data, as well as insights based on Effectv’s campaign ad exposure data for both traditional TV and streaming content.

According to an analysis of more than 20,000 Effectv cross-platform campaigns, streaming consistently served as a strong complement to traditional TV campaigns in the first half of 2021. In fact, 57% of reach from streaming in those campaigns was incremental to linear TV campaigns. Additionally, streaming impressions were +209% more likely to be served within households that viewed little or no traditional TV. This proves that complementing traditional TV strategies with premium long-form streaming will grow incremental reach and increase exposure with households less likely to be tuning in the traditional way.

This is only half the press release; I’ve highlighted in yellow the part I’m feeding the AI:

I want the AI to autocomplete the rest of it. Let’s see how it did:

“Our data shows that traditional TV and streaming are complementary platforms, which is why we’ve invested so heavily in both,” said Mark O’Neill, senior vice president, Ad Sales. “We’re seeing strong results with streaming, and we look forward to sharing more insights at the upcoming IBC in September.”

Viewership Trends

TV Viewership Trend Analysis

With the recent U.S. restrictions on travel and gatherings, viewership of national, regional and local channels has been declining in most markets. For those channels that are continuing to deliver, the decline is expected to be between -7% to -19% in 2021.

Comcast

For the first half of 2021, total viewership of all channels declined by +3% from the first half of 2020. Viewership of NBC-owned networks (NBC, Telemundo and CNBC) declined by -15% to -11%. Viewership of Fox-owned networks (Fox, FX, FS1 and FS2) declined by -7% to -10%. Viewership of ABC-owned networks (ABC, Freeform and ESPN) declined by -7% to -9%. Viewership of CBS-owned networks (CBS and CW) declined by -4% to -9%. Viewership of the CW declined by -6% to -4%. Viewership of Univision networks (Univision, UniMas and Galavisión) declined by -3% to -2%. Viewership of PBS declined by -3% to -2%. Viewership of independent channels declined by -6% to -13%.

In total, the largest decline in viewership among the national and local channels was among NBC, ABC, CBS and CW networks. The Fox network showed the second-largest decline, followed by Univision and PBS. These results are consistent with the recent ad spending trends on these channels.

Streaming Performance

With the growth in streaming services such as Netflix, Amazon Prime Video and Hulu, streaming impressions have grown at a rate of +11% to +21% year-over-year. Additionally, impressions of streaming campaigns were +21% more likely to be served in households that viewed little or no traditional TV, which is a reflection of the strong viewing patterns of streaming. In contrast to streaming impressions, impressions of traditional TV campaigns showed a decline of -3% to -4%.

What we see is that for a mediocre piece of content – a bland press release – the AI did astonishingly well. The data is likely not factually correct, but it captured the tone quite well. This would, at the least, be a great first draft that an editor could tune up and be ready to publish in short order.

Now, let’s try it with something more unique and distinct. I subscribe to and enjoy Tom Webster’s weekly newsletter, I Hear Things. It’s a fantastic newsletter about all things audio, so if you care about stuff like radio, audio, audio ads, podcasting, social audio, etc., you should subscribe to it. One of the things that’s distinctive about Tom’s newsletter is his written style. It’s very unique. Here’s a sample of a passage from the most recent issue:

This can be a difficult statement to fill in for the average podcaster. What is the thing that only your podcast provides for its intended audience? Not being able to formulate this kind of statement for your show is problematic not only as a hinderance to promote your show, but also as a trailing variable for a deeper problem: an inherent lack of differentiation with the show itself.

It’s definitely a thing I thought about first when I decided to create a podcast version of this newsletter. I started the I Hear Things podcast initially as a service for those who told me they sometimes didn’t have time to read my newsletter, but could always make time to listen to it. Thus, the podcast was born, but “The Podcast For People Who Like To Read I Hear Things But Don’t Have Time” is not the most compelling pitch I’ve ever heard. It probably ranks right ahead of “The Podcast That Won’t Give You Leprosy.” This is both of those things.

But there was an ulterior motive to the podcast.

As before, I’ll highlight the part I’m feeding to the machine:

click for a full size image

Now, let’s see how well the state of the art natural language generation model does, a model trained on all the data I shared earlier:

But there was an ulterior motive to the podcast. When I first started listening to podcasts, I found most of them to be like a car commercial; they all talk about the same things and the people that they’re talking to don’t really give a shit. I’m not sure why, but this seems to be a common pattern. You’ll be watching a movie and it’ll be full of some bullshit talking heads that go on about some movie you’re about to watch. You’ll have the same thing when you’re listening to an audio book. Or, you’ll be at the gym listening to some exercise podcast that goes on and on and on about the best workout routines and all of that stuff. I was sick of that, so I made I Hear Things.

And when I tell people about I Hear Things, I always get an equally strong response that it’s about the opposite. It’s not all about what we’re gonna talk about, it’s about what we’re gonna NOT talk about. I Hear Things is all about different people from different walks of life, so when I was doing it, I had no idea that I would discover the show that I Hear Things eventually became. But in the end, it has. It has a unique tone, and I know what I’m getting with this show. I want you to do the same. If you make a podcast about the things that you’re interested in, chances are you can find some people who are like minded and who are also interested in the things that you’re interested in. If that’s you, then the I Hear Things podcast might be for you. And I want to hear from you, the listener. So if you’re interested in what the I Hear Things show is about, give us a call at 1-800-917-3116.

What the machinery came up with was coherent and readable, but it was not at all close to what Tom wrote. It also changed voice – Tom’s tone and use of language is very specific. It’s conversational to a degree, but with a sense of formality, a sense of poise as though each word was chosen carefully. What the machine spit out is… not that. It comes across more like what a Joe Rogan or a Howard Stern might write.

Because Tom’s writing style is so distinct, it would be very difficult to build a model around it. It would even be tricky, because he’s written comparatively little, to fine-tune a model around it – and doing so would be at a very high computational cost. It can be done, but it’s not something the average marketer is going to have the time or talent to dol

This is why I’m bullish on AI for general, mediocre content creation at scale. It’ll do a great job of it, and be affordable for everyone. But this is also why I’m bearish about AI creating something truly great, because greatness is scarce. The more scarce, the harder it is for anyone – man or machine – to replicate it.

One final bit of food for thought: if you feed your own writing into a machine learning model and what comes out is equal to or better than your writing, that’s probably a sign that you need to level up your writing. Your writing sits in the middle of the bell curve, and for both personal and professional reasons, it needs to move to the outer edge of excellence.
