He’s on fire! How the hot hand helped Golden State become NBA champions (Synopsis) [Starts With A Bang]

“Success isn’t a result of spontaneous combustion. You must set yourself on fire.” -Arnold Glascow

When someone makes a shot, it’s a little instinctive to want to give them the ball again to see if they’ll make another. If they make three or four in a row, you’ll really want to ride that ‘hot hand’ as far as it will go. And if your teammate has made six, seven, or eight shots in a row, you know you’re beginning to witness something very special. There’s nothing like getting hot in quite that way.

Except, for decades, statisticians have been telling us that the hot hand is nothing more than a fallacy, the way we convince ourselves that you can better predict the results of a coin flip or a roulette wheel based on prior results. This was based in solid enough numbers, but there was a flaw: by selecting for streaks in the first place, the scientists doing the analysis had restricted their choices! When you account for that restriction, it turns out that the “hot hand” is very real.

NBA Jam may have had it right after all: when you hit a streak of three or more, some NBA players are quite figuratively ‘on fire’ for a prolonged time. Image credit: Robert Emerson / EA Sports.

NBA Jam had it right all those years ago. For some players, they really do go into an “on fire” mode that makes them streakier — for better and for worse — than others.
