Readers and former readers of science journals and magazines will be able to complete the famous line.

“…reduces an entire mouse to a soup-like homogenate in 30 seconds.”

It’s like the “They laughed when I sat down at the piano” of laboratory advertising. There should be an awards show and a coffee table book about this ad.

Famous Polytron ad

The Polytron ad keeps getting shared. On Reddit, you can spot it on r/vintageads, r/WTF, and elsewhere. It popped up on science Twitter when that was a thing. The Polytron has entered popular (laboratory) culture in a big way. It’s Kevin Simler’s “cultural imprinting” effect in action, within a subculture. And it’s effective. Try finding a lab that processes samples and doesn’t have a Polytron, and look how many scientific papers include Polytron in their materials and methods.

But I have never seen a Polytron used on an entire mouse. Even mouse researchers generally instead [icky mouse processing redacted, you’re welcome]. The ad is terribly non-personalized. The cultural imprinting effect of an long-running campaign, and the attention-getting effect in the reader’s imagination, outweigh the effect that could have been achieved by dropping in an “AI” headline that personalizes a sample type and homogenization time for each reader based on their own research interests.

Cultural imprinting isn’t just a mass media thing, like the often-repeated beer jingles that George Tannenbaum (and many others) remember from baseball games on the radio. Cultural imprinting can work in a subculture or community of practice, if you meet the people where they are. And trying to do that with general-purpose surveillance advertising is less and less effective for more and more communities, where the most engaged people are getting the best privacy protections. Advertising to subcultures and communities of practice is hard, and it gets both harder and more interesting when the people being advertised to are making a point of blocking or even spoofing the conventional measurement tools. Higher-quality ad creative, coupled with high-reputation media buys or sponsorships, are going to be increasingly important for reaching low-surveillablity niche customer communities.

What reminded me of this was The Paradox Of Personalization: Billions Of AI-Tailored Ads Creates A Measurement Mess by Erez Levin. We must reject the fantasy of infinite creative variations – not just because it is technically impossible but because it fundamentally misunderstands how advertising works for the vast majority of brands. (IMHO, brands are a cognitive hack that uses our existing monkey reputation brain wiring, that we’re already equipped with at the hardware level, to help us participate in markets, where are too new on an evolutionary time scale to have built-in support.)

Brands are built on a collective understanding of what a brand stands for. When you fragment that message into infinite, hyper-personalized silos, you destroy the macro-cultural signal that gives a brand its authority and prestige. It dilutes a shared asset into statistical noise.

Anyway, read the whole thing.

Where cultural imprinting adds risk

In the case of the Polytron, cultural imprinting is a win, because it’s a good idea to have a Polytron in the lab. It works on a large variety of materials, it’s easy to keep clean, it’s surprisingly quiet considering the specs, and if it turns out you don’t need it for now, it only takes a little bit of space and could be useful on a future project.

Cultural imprinting can go both ways, though.

Jessica Orwig, Leon Siciliano, and Lara O’Reilly cover Your candy ads are about to get a lot more personalized, Mars says. Rankin Carroll, chief brand officer of Mars Snacking, says the company behind your favorite candies like M&M’s, Snickers, Skittles, and Twix is reworking how it advertises to consumers — and the shift could mean people start seeing very different versions of the same candy campaign.

Regularly eating high-sugar foods in the middle of the day wasn’t always a thing, and people were probably better off. Cultural changes, driven by advertising, normalized the snacking habit. But now Mars is using “AI” to increase the personalization—which likely means that machine learning systems will “learn” to candymax the people at risk of eating disorders for a quick revenue hit, while pulling back on reinforcing the cultural acceptance. Mars may be opening up an opportunity for cultural imprinting of an alternate habit.icymi: Finally, The True Value Of A Facebook Fan by Bob Hoffman
