最後有一個叫「Comprehensive Assessment of Sadistic Tendencies」嘅sinister-sounding test,入面嘅Statement會近似「我成日都整蠱人,尤其當人地發現我做緊乜嘅時候特別爽皮」,用嚟評測班友幾鐘意虐待人。
OK,重點嚟啦!研究結果得出,鐘意「苦」嘅人係「emerged as a robust predictor for Machiavellianism, psychopathy, narcissism and everyday sadism」,唔鐘意「苦」嘅人係比較有agreeableness,即是條友比較 kind, sympathetic and cooperative。你地睇吓身邊啲朋友,就知個研究有無說服力啦。
