This article describes seven myths regarding the gene-environment debate that permeate the thinking of many educators and psychologists. These myths can lead to serious misinterpretations of the role of genes in behavior and to false conclusions regarding the modifiability of behavior. We examine each myth, dispel it, and state what we believe to be correct conclusions from different kinds of behavior-genetic and related data.
