The relationship between completed education and adult cognition is investigated using data from the Indonesia Family Life Survey. We compare adult siblings to account for shared, difficult-to-measure characteristics that likely affect this relationship, including genetics and parental preferences and investments. After establishing the importance of shared family background factors, we document substantively large, significant effects of education on cognition in models with sibling fixed effects. In contrast, the strong positive correlation between education and adult height is reduced to zero in models with sibling fixed effects, suggesting little contamination in the education-height association beyond factors common to siblings.
利用印度尼西亚家庭生活调查的数据，研究了完成的教育与成人认知之间的关系。我们比较成年兄弟姐妹，以考虑可能影响这种关系的共同的、难以衡量的特征，包括基因、父母的偏好和投入。在确定了共同家庭背景因素的重要性之后，我们在具有兄弟姐妹固定效应的模型中记录了教育对认知的实质性重大显著影响。相比之下，在具有兄弟姐妹固定效应的模型中，教育与成人身高之间的强正相关降至零，这表明除了兄弟姐妹共有的因素外，教育与身高之间的关联几乎没有干扰因素。
