“When Professor Little introduced the concept of self-monitoring to his personality psychology classes, some students got very worked up about whether it was ethical to be a high self-monitor. A few “mixed” couples—HSMs and LSMs in love—even broke up over it, he was told. To high self-monitors, low self-monitors can seem rigid and socially awkward. To low self-monitors, high self-monitors can come across as conformist and deceptive—“more pragmatic than principled,” in Mark Snyder’s words. Indeed, HSMs have been found to be better liars than LSMs, which would seem to support the moralistic stance taken by low self-monitors.”
