Mathematik und Sprachlicher Ausdruck:

Gemäß Robin Hanson, ahnen die meisten Personen noch nicht einmal, wie schlecht sie schreiben. Bezüglich mathematischer oder technischer Fähigkeiten finden sich häufiger zutreffende Selbstbewertungen:

"Long ago when I first started teaching undergrads, I noticed that while they were equally bad at math and writing, they could more easily see that they were bad at math. So they were happier to get writing assignments. Math assignments made them face the uncomfortable fact that they were bad at something valuable, while writing assignments did not. So students liked my classes better when I assigned writing more."
