The passage around this formula
The logarithmic score , used by Metaculus, is if the event occurs and if it does not. This is a platform claim and design note , not independent research: Metaculus documents that the log score is far more punitive of confident misses than the Brier score is rewarding of confident hits — moving from 99 percent to 99.9 percent gains almost nothing if correct but costs roughly 2.3 points if wrong [ 7 ] . That asymmetry is deliberate: it is what makes the rule “strictly proper” in Gneiting and Raftery’s sense, because it punishes the temptation to round an honest 90 percent up to a persuasive-sounding 99 percent.
