primary psychopahy is caused by genetis to about 80% according to the latest papers .The rest seems to be dependent on chance, not really on the envoironment. Secondary psychopathy (more like aspd) seems very linked to experience on the other hand.
按这报告,aspd(反社会人格)恰好是后天环境导致的,基因导致的是Primary psychopahy(原发性精神病),这正好说明了后天环境有多重要,翻译成中文似乎刚好把结论说错了
