Years of education		−0.308 [−0.573, −0.044]		−0.583 [−1.220, −0.019]
Polygenic score	0.184 [0.109, 0.259]		0.097 [0.025, 0.169]
Observations	3935	3935	3935	3935

Note: 95% CI is reported in the bracket. All Regressions include respondent's age, age square, gender, and top 10 principal component for their respective population stratification. The covariates adjusted model additionally includes mother's year of education, father's years of education, and area of birth. DWH refers to the Durbin-Wu-Hausman test.
