Adam Alter

Who they are

Adam Alter teaches marketing and psychology at NYU Stern School of Business, where his research sits at the boundary between social psychology and consumer behaviour: how names, colours, labels and interface design steer decisions that people experience as freely made. He has written three trade books for a general audience, each aimed at a different piece of that territory.

The most useful thing about Alter's body of work is not any single finding but the shape of it over time. Drunk Tank Pink (2013) leaned heavily on the social-priming literature that was dominant in social psychology at the time, citing studies on physical warmth, money priming and colour effects that would go on to fail large-scale replication attempts within a few years of publication. He flagged the weaker evidence in his own endnotes, including the mixed record of the Baker-Miller pink effect the book takes its title from. But the book is, in retrospect, a snapshot of a field taken just before a large part of it collapsed under scrutiny.

Irresistible (2017), published four years later, argues a related case, that technology products are engineered to be habit-forming, using a different kind of evidence: behavioural data, industry practice and interviews rather than priming studies. Read next to Drunk Tank Pink, it reads as a researcher adjusting his standards of evidence in real time, without ever announcing the correction. Anatomy of a Breakthrough (2023) moves away from addiction and persuasion entirely, toward the psychology of getting unstuck on hard problems.

Key ideas

The correction arc. Alter is the clearest case in this vault of a popular-science author visibly adjusting to the replication crisis between two books. Drunk Tank Pink built its case on studies such as Williams and Bargh's coffee-cup warmth priming and Vohs's money priming, most of which did not hold up in high-powered replication attempts in the years after publication. Irresistible does not repeat that mistake, resting instead on behavioural evidence and industry practice. Alter never states the shift as a correction, but the pattern is there for anyone reading the two books in order. See the replication crisis.

The six-ingredient model of behavioural addiction. Irresistible's central contribution is a diagnostic checklist for whether a product has been engineered to hook its users, covering goals, feedback, progress, escalating difficulty, unresolved tension and social interaction. It functions less as a theory than as an audit tool, and it is the piece of Alter's work most directly useful to anyone assessing a product's design. See behavioural addiction and behavioural architecture.

Variable rewards and operant conditioning. Alter draws the same line from B. F. Skinner's operant conditioning experiments to app design that Nir Eyal draws, treating unpredictable reward schedules as the engine behind compulsive checking. See variable rewards.

What held up and what did not. Alter's own research on processing fluency, how easily a name or a piece of text is parsed, has replicated well and remains one of the more durable findings in Drunk Tank Pink. The material that did not hold up was largely other researchers' priming work he was reporting on in good faith, not his own experiments, a distinction worth keeping in mind before treating the book as a cautionary tale about the author rather than about a field.
