Because it takes a lot of skill to be "always wrong" (you would have to know the right answer in order to answer incorrectly). No skill is represented by getting 50% right/wrong, and indeed it scores you 0 points.
- scott_s 10y agoI don't think that answers mikeash's question. He is not talking about always being wrong. He is pointing out that the incentives are not symmetric. If you say that you are 100% certain, and you are wrong, then you fail the class. If the incentives were symmetric, if you said you were 100% certain and you were correct, then you would automatically pass the class. A potential answer is: this asymmetry is similar to incentives outside the classroom. Claiming 100% certainty and being wrong can be disastrous to your reputation, and likely much more negative than the positive benefits of claiming 100% certainty and being correct.
- mikeash 10y agoGetting 50% right/wrong while expressing 100% confidence in your answers scores you negative infinity points. Indeed, getting 99.9% right/wrong while expressing 100% confidence scores you negative infinity points. But getting 100% right with 100% confidence only scores you a finite positive number of points.
