We all like to believe we’re logical creatures. You know, weighing the pros and cons, doing the cost-benefit analysis in our heads before every decision. But then one fine day, you walk into a store and walk out with something that was on “Buy 2 Get 1” and no plan whatsoever of using even one.

At B-school, you’re taught frameworks, strategy, theory, all the good stuff. But somewhere between that one weirdly overpriced sandwich and the pile of unused coupons sitting in our inboxes, we realize there’s more to decision-making than just logic. That’s where behavioral economics strolls in—quietly, cleverly, and always with an example that makes you go, “Wait, I’ve done that too.”

Whether it’s a class case study or a real-life coffee order, you start seeing patterns. Like why we always choose the “recommended” option. Why a red ‘Sale’ tag gives us more joy than the actual discount. Or why we’ll pay more for something just because a celebrity once blinked at it on Instagram. The terms might sound academic—anchoring, loss aversion, social proof—but the behavior? Very, very human.

I remember a moment during a classroom discussion where a simple question—“Why did you pick that product?”—turned into this layered conversation about familiarity, fear of missing out, and even our childhood preferences. It was funny, and oddly humbling, to realize how little control we sometimes have over our own choices.

But here’s the fun part: once you spot it, you can’t unsee it. Every ad, every app notification, every well-placed default option starts to look like a well-rehearsed psychological nudge. And in that recognition lies power—not just as a consumer, but as a future marketeer, strategist, or entrepreneur.

Behavioral economics doesn’t give you a rulebook. It hands you a mirror. It reminds you that humans aren’t always rational—but we’re predictably irrational. And sometimes, understanding that irrationality is the smartest decision you can make.

So the next time you catch yourself choosing the middle option, panicking over sunk costs, or buying something “just in case”—smile. You’re not alone. Behavioral economics is simply life with subtitles. And understanding it? That might just be the smartest irrational move you make.
