近日,，發(fā)表于《人格期刊》（Journal of Personality ）的一項(xiàng)研究認(rèn)為,，有些人一出生就注定功成名就。他們表示,，成功的動(dòng)力就藏在基因里,，DNA決定了我們未來是否能夠成功。
研究顯示,，人們是否有決心,、社交與自我控制能力的強(qiáng)弱,，多受基因支配。事實(shí)上,，DNA對(duì)于這些特征的影響力,，比成長環(huán)境和結(jié)交人群等因素還大。
愛丁堡大學(xué)研究人員表示,，整體而言,，這些人格特質(zhì)能夠決定將來人們能否成功。
研究人員調(diào)查了超過800對(duì)雙胞胎的生活態(tài)度,，以區(qū)分先天與后天帶來的影響,。比較同卵雙胞胎與異卵雙胞胎間的差異，是研究人員常用來量化基因影響力的方法,。同卵雙胞胎DNA與父母養(yǎng)育方式相同,，異卵雙胞胎出身背景相同，DNA卻相異,。
這項(xiàng)研究指出,，基因?qū)τ趥€(gè)性的影響大于生活方式，自我控制力尤其深受DNA影響,。
基因大體上能決定我們的決心與毅力有多強(qiáng),，就追求成功而言，這點(diǎn)極為重要,，因?yàn)榫芙^放棄的人比遭遇小失敗就退卻的人,，更易達(dá)成夢(mèng)想。
不過就算沒有“成功基因“的人也不需太過沮喪,，因?yàn)檠芯咳藛T表示,，是否有明確目標(biāo)也是能否成功的一大關(guān)鍵，并建議渴望成功的人讓自己與眾不同,。（生物谷Bioon.com）

Genetic influences on psychological well‐eing: A nationally representative twin study
Archontaki, Despina; Lewis, Gary J.; Bates, Timothy C.
OBJECTIVE: Psychological well-being, or eudaimonia, features strongly in theories of human development and thriving. However, the factors of eudaimonia are debated, and their genetic architecture has not been studied in detail. METHOD: A classical twin design was used to decompose behavioral variance into genetic and environmental components implemented in a multi-group, multivariate structural equation modeling framework. Subjects were 837 pairs of adult US twins from the nationally representative MIDUS II sample. Psychological well-being was measured using the 42-item Ryff Psychological Well-being Scale, which assesses autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance. RESULTS: Substantial genetic influences were observed on all components of well-being. Attempts to model these 6-factors as reflecting a single common psychological mechanism gave a poor fit to the data. The best-fitting model supported the existence of five distinct genetic effects. Effects of shared-environment were weak and non-significant. Unique-environment effects for all measures were mostly trait specific. CONCLUSIONS: These results indicate that psychological well-being is underpinned by a general genetic factor influencing self-control, and four underlying biological mechanisms enabling the psychological capabilities of purpose, agency, growth, and positive social relations.
