Series: The Psychology of Money

Season 1: Traps We Fall Into

Leo Predicted the Stock Perfectly. Or Did He?

Hear Leo brag about his investment success — and then listen as Ms. Reed challenges what he actually felt before it happened.

Leo is excited. His stock investment went up. He’s telling his friend Carlos: “I knew it would happen. It was a sure thing.”

Ms. Reed overhears from the next bench. She waits for a pause in the conversation, then asks him a simple question.

“How certain did you actually feel before the stock went up?”

Leo opens his mouth to answer. Then stops.

He remembers the morning he bought it. He remembers checking the news twice. He remembers texting Carlos: “I think this might work — not sure though.” He remembers the doubt. The uncertainty. The small knot in his stomach when he hit confirm.

But that’s not what he just said to Carlos. What he just said was: “I knew it would happen.”

“You remembered it differently than it happened,” Ms. Reed says.

This is hindsight bias — the tendency to believe, after an outcome is known, that you predicted it all along. The brain rewrites the memory. The doubt disappears. The uncertainty gets replaced with confidence that was never really there.

It feels good. That’s the problem. Hindsight bias makes you feel like a better decision-maker than you are. And that feeling leads directly to the next bad decision — the one where you’re so confident in your own judgment that you stop asking the questions that would protect you.

Leo thinks about the “sure thing” he’s already planning to invest in next month. The one he hasn’t told Carlos about yet because he wants to surprise him with the results.

Ms. Reed doesn’t tell him not to do it. She just asks: “Before you invest, write down exactly how confident you feel and why. Then read it again after.”

The lesson: Success doesn’t mean you predicted correctly. It might mean you got lucky and remembered it wrong. The most dangerous investor is the one who has confused the two.

The English You’ll Acquire in This Episode

This episode introduces a cluster of vocabulary that is essential in any professional context involving forecasting, strategy, or post-project review: hindsight bias, overconfidence, confirmation bias, outcome bias, due diligence, risk assessment, prediction vs. outcome. These are the words used in investment meetings, consulting debriefs, and any professional conversation where someone is trying to understand whether a good result came from good thinking or good timing.

The conversation between Leo and Carlos also gives you something specific: the English of casual confidence — how young professionals talk about money, predictions, and success when they’re trying to impress each other. That register is different from how Leo speaks with Ms. Reed, and hearing both in the same episode gives you a natural feel for code-switching between informal peer conversation and more reflective, analytical dialogue.

Where This Fits in Leo’s Story

By this point in The Traps We Fall Into, a pattern is emerging. In the previous episode, Leo couldn’t switch bank accounts despite knowing it was the rational choice. Here, the problem is the opposite: he’s moving too confidently, rewriting his own memory to make himself look smarter than the situation warranted.

Part 1 of Psychology of Money showed Leo the forces working against him from the outside — social pressure, inherited beliefs, loss aversion. Part 2 keeps showing him the forces working against him from the inside. The bank account was about inertia. This episode is about overconfidence. The episodes that follow — The Discounted Sweater and Birthday Money vs Work Money — continue the same excavation, each one revealing another layer of the gap between how Leo thinks he makes decisions and how he actually makes them.
