Here is a new post at EconLog in which Bryan Caplan discusses how signalling contributes to the status quo bias.
The lesson: In the real world, signaling naturally tends to ossify behavior - to lock in whatever the status quo happens to be. If you're an optimist, you can protest, "It's only a tendency." But even an optimist should admit that this tendency leads to atypically slow and unreliable progress.
"Intercultural conformity comparison" doesn't seem like a trivial problem to me. What it means to conform is different in different cultures. In Japan it might mean using polite language. At Burning Man it might mean not being greedy (based on skimming the Wikipedia article; I have no first-hand experience). People at Burning Man might care less about polite language, but that just suggests that they use something other than polite language as a social signal of respect. It doesn't mean they've stopped caring entirely about the concept of respect.
Chanting "nonconformity" doesn't make you a nonconformist any more than chanting "rationality" makes you a rationalist.
I still think expectations of conformity are largely cultural. "Different cultures demand conformity in different ways" is a compatible assertion. It would be interesting if total conformity demands tend to sum to the same number across cultures, but that seems really unlikely to me.
