Probably has more to do with how they regard hallucinations. In some cultures they're regarded as possibly mystical and a good thing, in other cultures they're regarded as strictly a sign of a malfunctioning brain which is of course bad. Even a corpse can create different feelings based on context and beliefs-- ie a corpse at a funeral is a somber memorial, a corpse lying in the street is sad and worrying.

I didn’t say inner voices are scientifically correct. I think they’re an adaptation. Maybe if India had more functioning depressives it wouldn’t be in that situation, who knows?

And you’re not as skeptical of this claim?
