吝嗇無罪！ 科學家找到「小氣基因」

到了結帳時刻，總會發現特定友人忽然消失？德國波昂大學（University of Bonn）的研究發現，這種令人生氣的行為，源於「小氣基因」，而且平均每4人就有1人有這種遺傳基因，所以他們天生愛財如命，是名副其實的「鐵公雞」！


研究團隊從101名年輕男女的口腔採集細胞樣本，檢驗一種名為「COMT」的基因，這種基因已知會影響腦部化學作用，分為G和A兩種形態，團隊認為「COMT」也會影響人是否大方不吝啬。


研究人員給受試者看秘魯貧童「莉娜」的照片，還有她手工編織的手環，告訴他們將玩一種電玩賭博遊戲，希望他們可以從其中捐一些錢救濟小女孩，捐出全部或部分獎金都可以，金額沒有設限。


結果，帶有G型「COMT」的受試者中，逾20%把獎金全數捐給莉娜，但帶有A型的卻不到2%，平均而言，帶有A型「COMT」這種基因的受試者，捐款總額不到全部捐款一半，顯示帶有A型「COMT」者天生擁有「小氣基因」。


不過，「小氣鬼」可不要開心的太早，心想終於有合理的藉口可以一毛不拔，因為曾有研究指出，吝嗇與否不僅受先天基因影響，與後天教養和宗教等因素也有關聯。這項研究報告發表在《社會認知與情感神經科學》（Social Cognitive and Affective Neuroscience）期刊。

我想要這個基因 (偽可愛)

我想要這個基因 (偽可愛)

偶家董事長有，但她捨不得轉讓。 (不要啊)

[forester]

依照這個實驗
為何推定為小氣基因
而不是同情心基因
(咦) (咦) (咦)

我的冤屈終於可以洗清了... (遠目)
