The author replies to a critique by Lidz and associates of the Greater
Copenhagen Adoption Study conducted by Rosenthal and colleagues. A detailed
examination of the reanalysis by Lidz and associates of tabulated data from
the original adoption study reports substantiates only one of their
objections. The author argues that, because of the way in which the
original data were gathered, the reanalysis is without substantial merit in
evaluating the adoption study.Abstract Teaser
