Hesitation

Hesitation is not cowardice, and it is not a character flaw. It is a *learning bug*, and it has a name in the research literature. ### The hot stove effect In *Adaptation as Information Restriction: The Hot Stove Effect* (Organization Science, 2001), Jerker Denrell and James March showed that learning from experience is systematically biased against risky alternatives. The reason is mechanical: once an option burns you, you stop choosing it, and if you stop choosing it you never gather the evidence that would correct your estimate of it. Options you have underrated do not get sampled again, so the error never gets fixed. What looks like risk aversion is really a starved data set. That is your hesitation, exactly. Your setup lost three times in a row. Nothing about the setup changed, but your brain has repriced it as bad, and the only thing that could reprice it correctly is taking it again, which is the one thing the fear will not let you do. This is why "try harder" and "be more disciplined" bounce straight off. You cannot willpower your way out of a sampling problem. ### What the freeze actually costs The damage never shows up in your journal as a loss, which is why it stays invisible. It shows up as the trade you skipped, followed by the chase after price has already run. Now you are entering late, your stop is either wider or in a worse place, and the reward-to-risk you turned down was better than the one you just accepted. Worse, chasing means crossing the spread in a hurry, and the Taiwan study by Barber, Lee, Liu and Odean (Review of Financial Studies, 2009) found that virtually all individual trading losses traced back to exactly those aggressive, get-me-in-now orders. Hesitation rarely stays hesitation. It converts into FOMO, at a worse price. ### The fix is sampling, not courage - **Reps on demo or in backtest.** This is forced re-sampling. You take the setup enough times, where the outcome cannot hurt you, to rebuild the evidence the hot stove effect stole from you. - **Mechanical entry criteria in your trading plan.** If conditions X, Y and Z are true, you enter. "How I feel about my last trade" is not X, Y or Z. The plan exists to remove the decision at the exact moment your fear is loudest. - **Shrink, rather than skip.** If full size freezes you, a smaller position you actually execute keeps you sampling, and sampling is the thing that heals this.
