We thank Adolf and Fried (2019) for their insightful commentary on our paper (Fisher et al., 2018). We agree, in principle, that group-to-individual generalizability lies along a continuum. Some intraindividual and interindividual statistical estimates may be ergodic, sharing equivalent values across all statistical moments. Under these conditions, inferences from cross-sectional data could be applied to individuals. On the other end of this continuum, intra- and interindividual estimates are orthogonal, rendering them unrelated and nontransferable.
