Abstract: To the Editor: We respect Border et al.’s ambitious undertaking (1), which was published in the May 2019 issue of the Journal. We endorse greater scrutiny of novel effects within the literature on gene-by-environment (G×E) interactions, including replication using highly powered methods. We argue, however, that the approach used here to measure the environment—several dichotomized questionnaire items—is insufficient to draw conclusions, despite probing measurement error. Evidence for the importance of the environment for depression is well established (i.e., approximately 63% of liability; [2]), and vulnerability-stress models of depression are widely endorsed and long precede G×E research. However, G×E research has failed to invest in measuring the environment (3); we urge adoption of “E” assessment that matches the rigor of “G” assessment.
