生まれか、育ちか

生まれか、育ちか

Nature or Nurture

生まれ = 遺伝的影響

育ち = 養育環境

parental environment だと養育、教育というよりは「親の志向」みたいな感じ?

In a unique sample of 394 adoptive and biological families with offspring more than 30 years old, biometric modeling revealed significant evidence for genetic and nongenetic transmission from both parents for the majority of seven political-attitude phenotypes.

We found the largest genetic effects for religiousness and social liberalism, whereas the largest influence of parental environment was seen for political orientation and egalitarianism.

Together, these findings indicate that genes, environment, and the gene–environment correlation all contribute significantly to sociopolitical attitudes held in adulthood, and the etiology and development of those attitudes may be more important than ever in today’s rapidly changing sociopolitical landscape.

30歳以上の養子・実子をもつ394組の家族という類例のない標本において， 生体測定モデリングにより，次の点を支持する有意な証拠が明らかとなった

7項目の政治的態度の表現型の大多数で両親からの遺伝的・非遺伝的な継承がなされている

宗教心と社会自由主義でもっとも大きな遺伝的影響が見られる

genetic effects

religiousness

social liberalism

養育環境の影響がもっとも大きかったのは政治的な指向と平等主義だった

parental environment

political orientation

egalitarianism

こうした発見からは，遺伝子、環境、遺伝子と環境の相関関係、のすべてが成人期の社会政治的態度に有意に寄与することが示される．こうした態度の原因や発達に関する知見は，急速に変化する今日の社会政治的な様相において，いっそう重要かもしれない．

Abstract

Where do our political attitudes originate? Although early research attributed the formation of such beliefs to parent and peer socialization, genetically sensitive designs later clarified the substantial role of genes in the development of sociopolitical attitudes. However, it has remained unclear whether parental influence on offspring attitudes persists beyond adolescence. In a unique sample of 394 adoptive and biological families with offspring more than 30 years old, biometric modeling revealed significant evidence for genetic and nongenetic transmission from both parents for the majority of seven political-attitude phenotypes. We found the largest genetic effects for religiousness and social liberalism, whereas the largest influence of parental environment was seen for political orientation and egalitarianism. Together, these findings indicate that genes, environment, and the gene–environment correlation all contribute significantly to sociopolitical attitudes held in adulthood, and the etiology and development of those attitudes may be more important than ever in today’s rapidly changing sociopolitical landscape.
