This might depend on what else we know about it. Or don’t know. We know that reincarnation is real, but do we understand the “rules”?

Most reincarnation beliefs include some sort of points system for how you come back. For example, Good people come back better, and bad people become slugs. If it can be confirmed that suicide gets you demoted, there might not be people doing it.

Or, after enough people start rerolling, an official government agency “confirms” it just so they don’t lose their working class.
