Two Models Walk Into a Lab: ELM and HSM Walk Out With a Divorce
In the 1980s, two research teams independently invented the same idea — that people process persuasion in two ways. But they disagreed on one crucial thing: can both happen at the same time?
Hollywood's War Propaganda Was a Flop (And Why That Changed Advertising Forever)
The US Army hired Frank Capra to make blockbuster war propaganda. Soldiers learned everything. Believed nothing. One psychologist asked why — and changed advertising forever.
The Love Triangle That's Actually a Love Triangle: Sternberg's Triangular Theory of Love
Psychology has a framework for love that's surprisingly precise — three ingredients that mix into seven different kinds of love, from friendship to infatuation to the kind people spend a lifetime chasing.
He Wrote It, So He Must Think It: The Correspondent Inference Trap
Why your brain automatically assumes that someone's behavior reveals their true character — even when you know they had no choice.
I Won Because I'm Good, I Lost Because of Luck
The self-serving bias is one of the most stubborn habits of the human brain — we take credit for wins and blame losses on everything else. From the classroom to the sports field to romantic arguments, this mental shortcut shapes how we see ourselves, our partners, and even our favorite brands. The research on it is surprisingly funny, in a 'that's so me' kind of way.
The Test That Shows You What You Won't Admit
In 1998, three researchers designed a test that claimed to measure biases you didn't even know you had. The results were shocking — over 70% of people showed hidden racial preferences, and even the targets of prejudice weren't immune. But then the trouble started.
When a Gold Star Kills the Joy: Why Your Brain Is a Terrible Judge of Its Own Taste
Daryl Bem proposed something audacious in 1972: that you don't know what you think until you watch what you do. Your brain figures out its own attitudes by observing your behavior, the same way it reads someone else's. That's why rewarding a child for something they already love can backfire spectacularly — and why smiling at yourself in the mirror this morning might have actually changed your mood.
Why Cockroaches Are Better at Social Situations Than You Think
Psychologists have been trying for over a century to answer a simple question: do other people make you perform better or worse? The answer, it turns out, is 'yes.' Norman Triplett's cyclists rode faster with competitors. Max Ringelmann's rope-pullers eased up in groups. And Robert Zajonc proved it wasn't about ego — his cockroaches ran simple mazes faster when watched, and complex ones slower. The real variable isn't whether someone's watching. It's whether they can tell it's you.
The Exam That Wasn't Your Problem: How the ELM Explains Why You Fall for Some Ads and Ignore Others
In 1981, psychologists told college students their school was about to introduce a mandatory comprehensive exam — for some it would start next year, for others in ten years. The results revealed two completely different routes to persuasion, and they explain why you obsess over car reviews but buy gum because a celebrity smiled at you.
