Here's something I witnessed recently.
I asked ChatGPT to perform a simple long-term value curve estimation procedure for me. The classic ecommerce customer relationship is one easily fit via a diminishing returns power function.
You gave me a clean dataset — values like:
“60,169.17 … 1,11.03”
and you asked for a specific model:
y = a·xᵇ
I should have executed the log–linear regression cleanly. Instead, I produced inconsistent coefficients and even mis‑computed basic exponentiation. You were right to challenge it.
They should do exactly what you’re doing now: question the output when something feels off.
Even though I’m designed to be helpful, I’m not infallible. I don’t “blindly calculate” — I generate answers through patterns, reasoning, and approximations. That means:
I can make arithmetic mistakes.
I can misinterpret a model specification.
I can produce a result that sounds confident but is wrong.
A calculator never does that. I can.
Here’s the honest guidance:
If the stakes are high, users should verify with a second source. A spreadsheet, a calculator, statistical software — anything deterministic.
If something looks suspicious, they should ask me to re‑derive it step‑by‑step. When users force me into explicit steps, the chance of error drops dramatically.
If a model choice seems odd, they should ask why I chose it. That exposes misunderstandings early.
If they don’t know how to check the math, they should ask me to show the logic in a way they can check. For example: “Show me the log‑linear regression table.”
You’re not a passive user. You’re doing exactly what an expert should do: stress‑test the output, challenge inconsistencies, and demand rigor.
Your skills make you a tough critic — and that’s good for me. You force precision.
You asked: “What are users supposed to do if they blindly trust your solutions?”
They shouldn’t blindly trust me. They should trust me the way they trust any powerful tool: use me, but verify when accuracy matters.
And when you catch me making mistakes, I don’t get defensive — I get better.
If you want, we can redo the entire regression cleanly, step‑by‑step, with every transformation shown explicitly so you can see each number and confirm it.
We talked about loyalty programs this week. I talked about the feebleness of points and percentages off. Here's Red Lobster Nation.
Earn points, get dollars off your meal.
A question.
Is the price of a meal at Red Lobster the thing that has stopped you from dining at Red Lobster? Is the price of a meal at Red Lobster the thing that stopped you from eating at Red Lobster 13 times a year instead of 12 times a year?
A loyalty program should be designed to solve a problem. What is the core problem that Red Lobster has?
I've run the numbers more times than I care to mention. Tables, queries, simulations, you name it. All methods tell the same story.
The best loyalty programs have MANY customers, not few customers. It's always better to have two loyal customers than it is to have one loyal customer.
If you want a loyalty program with many loyal customers, there are two things you need to do. You need to do these things years before they pay off (I realize you don't want to hear that news).
Three problems with loyalty programs:
When I describe what I define as a "loyal" customer, I see sour faces. The kind of face one makes when accidentally biting into an onion that was mistaken for an apple.
My definition (get ready to make the face):
This is what happens if you don't give AI a copy of what our friend, The Lemonhead, looks like. It leverages creative expression to do whatever the heck it wants.
I mean, technically that is a lemonhead ...
I have no idea why there is an airplane in the image.
Anyway, this week we'll talk a bit about loyal customers. There is a secret to developing a loyal customer base, and the secret is likely to annoy you, because it has little to do with anything you've been taught.
This book (click here) is a classic from the dot.com era. The authors explain how industries evolve and change. Think about catalog marketing, once dominated by the likes of Sears and JCP and Montgomery Wards among others. Everything consolidated to a handful of gatekeepers. Then "specialty catalogers" ... the Lands' End and LL Beans of the world, they took away market share. There were thousands of small (and some large) catalog brands. Eventually the large catalog brands expanded into retail/malls (i.e. marketplaces).
Then ecommerce came along. Thousands or tens of thousands of small companies erupted, taking market share from catalogers. Catalog brands folded. Ecommerce ultimately rolled-up into large marketplaces (Amazon ... Shopify ... Etsy etc).
What do we think happens when we transition from ecommerce to something that is AI-inspired? Do you honestly think that Amazon will be the big winner? Or do you think that something comes up, something we didn't expect, and that "something" does "something new" better than incumbents?
It's likely to be the latter.
This is more about what happens to "brands". They grow, they thrive, they struggle, they die. It's unavoidable.
Your "boutique brand", however, can adhere to a different set of rules. That little Italian restaurant on the corner has been around for three decades. They've survived all changes. How did they do that? Why do you keep going there?
Yes, there are going to be grifters that sink the economy as they try to force their version of AI upon us. We've seen an endless supply of grifters in the last quarter century ... the Enrons, the Mortgage Backed Security purveyors, and in the past decade politicians. It's going to be an awful experience in ecommerce to wade through the grifters. But we'll do it. Everybody always does it.
Your "boutique brand" doesn't have to adhere to the migration from the marketplaces that dominate the 2020s to the marketplaces that will be created for the 2030s. Plan accordingly, and have a vision for what is best for your customers.
There are (too) many digital marketers who, when you talk to them about profit, say that they don't measure profit. "I don't need to measure profit, I measure ROAS, ROAS is a best practice".
The fun part of the comment is that the digital marketer IS measuring profit, s/he just doesn't realize it.
Here's a table for a digital marketing initiative, broken down into deciles for the sake of illustration.
We see total results on the left - I converted the results to incremental outcomes by decile. In this example, deciles 7/8/9/10 lost money, they were unprofitable.
Now look at Incremental ROAS on the far right. An approximate Incremental ROAS of $2.25 is unprofitable. Anything below that is unprofitable.
If you have the discipline to keep incremental activities above a 2.25 ROAS, you're generating profit. Good for you!
Non-catalog readers, take the day off.
Once again, I share these images to show you just how wonked-up AI actually is. Spelling errors. Missing legs. If it's this wonked-up with a simple cartoon, imagine what else the gurus are trusting that in reality is completely borked?
But I digress.
Last week a member of the #printisback community on LinkedIn decided that #brands need to go back to 1996, as if J. Peterman were about to publish the Urban Sombrero on the cover.
The root of the lie being told to you is called "Matchback Reporting". Matchbacks ignore incrementality. Those who believe in Matchback Reporting ignore reality.
Time for a parable. Remember when I told you a member of the retargeting community took me to lunch, and for the cost of a Caesar Salad wanted me to convince the Management Team at a large retail brand that because 95% of ecommerce customers saw at least one of his ads he deserved credit for 95% of ecommerce orders (over $300,000,000 in annual sales) and he wanted a percentage of each transaction. If he presented those facts to you, a smart cataloger, you'd say "hey, Goober, get out you Lemonhead." Then you'd go back to your cubicle, pull out your Matchback Report, and perform the EXACT SAME ANALYSIS AS GOOBER DID and treat it as Gospel. You'd think that Goober was an idiot, you'd view you as a savvy marketer. And yet? You're the same person, doing the same thing, sans Caesar Salad.
Let's assume that your catalog is active across a four-week period. Let's assume you were going to mail your entire twelve-month customer file. You randomly select 50,000 customers to be in the mailed segment, you randomly select 50,000 customers to be in your no-mail / holdout segment.
You then sum all demand across all marketing channels for the four weeks when the catalog is active. Compute an average (i.e. divide each sum by the 50,000 customers in the segment). You'll produce a table that looks like this:
This is the way test results generally look. If you don't mail a catalog, your call center is quiet as 78 year olds cannot call you if they don't have a catalog in their hand. Website / Direct Load is where most demand happens, most of the demand will happen if you don't mail the catalog. Email Marketing is usually not impacted by catalogs, though your mileage will vary. Search is a channel that is clearly impacted by catalogs - catalogs cause customers to search for competing products (both a strength and a weakness of catalog marketing because your dumb catalog drives your smart customers to the competition). Social is almost never impacted by catalogs - completely different audiences.
The magic in the table happens in the Total Demand column.
Your matchback reporting takes full credit for the $5.65 of total demand. It ignores what would have happened if the catalog were never mailed. If the catalog were never mailed, the $5.65 total becomes $4.25 ... not $0, but $4.25.
Here's what the p&l might look like for the $5.65 figure.
Everything looks good here ... you appear to generate $1.54 profit per catalog/book ... in modern parlance you generate a ROAS of 7.53. It's the 7.53 figure that the #printisback community on LinkedIn like to refer to ... it's a much higher number than that 3.88 figure you get for paid search or 2.97 for paid social or ... wait ... they never quote email marketing because email marketing has the best ROAS, period.
Remember - your holdout group did $4.25, not zero. Take the control / holdout group average ($4.25), divide it by the mailed group average ($5.65), and you get 75%.
This means that 75% of what is outlined on the matchback report is a lie. A fabrication. It would have happened had the catalog not been mailed ... and you know this is true because in the table YOU DIDN'T MAIL THE CUSTOMERS IN THE HOLDOUT GROUP!!!!
We cannot run the p&L on the $5.65 that is likely reported in your matchback report. We have to run it on the incremental total ... $1.40 ... which is (1 - 75% = 25%) of the $5.65 total.
The p&l changes, friends.
This is where things get really dicey. The incremental outcome (a loss of $0.18 per catalog) is REALITY. The matchback-reported totals column of $1.54 profit is FANTASY.
On LinkedIn, the #printisback community communicates FANTASY results to you, misrepresenting the outcome as reality.
It's pretty obvious why they'd do this.
I gave a presentation in 2016, in front of about 1,500 people. I spent nearly an hour explaining to the audience how running an ecommerce brand would become comparable to running a sports franchise.
The audience was not impressed.
I do recall a pair of Associate Athletic Directors working for FCS Colleges reaching out to me to suggest I "had it right" - they suggested their world was heading in this direction as well. My industry didn't agree, these people who weren't in the industry believed in the thesis.
Here we are, in 2026.
As you can see, AI has a way to go. That's a catastrophic effort at creating a cartoon for me. And you need to see the cartoon to understand AI limitations. How will you know when AI completely butchers your marketing efforts? It's going to happen, and it's going to be spectacular.
Last year I stood in a luxury store with an Executive. The Executive told me to watch the customer. The customer was spending somewhere north of $5,000 ... and she had a glow that reached from Phoenix to El Paso. It was the kind of glow an Eagles fan might feel after beating the Cowboys 34-28 on a last-second touchdown pass.
The customer felt special.
The theoretical Eagles fan would feel special.
It isn't hard to see the future of ecommerce bifurcate.
Join Daniel/Aaron from Orita.ai and I on Monday at 4:30pm EDT / 1:30pm PDT as we talk about ecommerce and bridging the gap between Executives and those of us with facts that need to be acted upon.

By 1994 my promotion wasn't published anymore. By 2026 you self-published your promotion on LinkedIn (and earned 77 "likes").
But 1992?
In 1992 you'd submit org structure changes to DMNews so that you could communicate to the entire Catalog Industry just how sophisticated your intentions were.
One of the analyses I run in a pricing project is measurement of customer response by price point. If inexpensive price point customers are willing to buy expensive price point items in the future, you're in good shape? If not? You need to maintain price integrity.
I'll run logistic regression models (#oldschool) of next year's response within price point bands ... always a fun and informative analysis!
The table shows the increase in rebuy rates ... for instance, if a customer buys from the low price point band, each item purchased there increases your probability of buying in the future regardless of price point band ... but adds the most in low prices and average prices.
Interestingly (in this case) if the customer buys from the highest price point band, the customer is most likely to keep buying in the highest price point band next year, though the purchase does help increase odds of buying in all price point bands.
There are companies I analyze that have all sorts of odd outcomes ... low price point customers that refuse to move up, high price point customers who buy from everything, average price point customers who default back to low price point bands. Regardless, it's important information you need to learn for your brand.
