這在心理學上被稱為“zeal of the convert”——皈依者狂熱。西方心理學者在研究宗教新信徒的相關案例時發現，通常認為並不完全虔誠的新信徒(畢竟受到之前生活經歷影響)，相反卻往往比“根正苗紅”的老信徒更加虔誠、更加狂熱——The zeal of the convert is a phrase describing the typically fierce devotion of someone whose belief system has changed because of personal experience or argument, especially as compared to someone who has held their beliefs since childhood. In addition to some empirical support of the phenomenon, the occasionally excessive fervency of converts has long been proverbial.(Pew Research Forum.)
