Finally, Eaves (2006) demonstrated that evidence of interactions between genes and “environments” can be an artifact of the scale used, rather than providing evidence of a true interaction between persons and environments, even when genotypes and environments are directly assessed. The same caveat might apply to studies of moderation, and thus we must accept that the GxM found here, while controlling for the confounding effects of rGE, may be also be subject to the same limitations and therefore specific to the measures used, thus any conclusions drawn from these results need to be treated with caution.
