You're right. That's why I was careful to qualify it with "all other things being equal."
In general identity gives you strength while making you stupid. This can sometimes be a good trade, especially in stressful situations. E.g. I think this is one reason people in the US are so much more religious than they were when I was a kid. People who 30 years ago might have been skeptical of preachers are now thinking that religion may at least save their kids from meth.
