Warrior genes and risk-taking science.

This article provides a summary of our ethical concerns regarding the so-called "warrior gene" line of research. Prompted by recent claims that there is a genetic explanation for negative social and health statistics for Māori, the article discusses issues related to informed consent of research participants, the validity of the underlying science related to the "warrior gene", and scientifically unfounded speculation regarding the causality of complex social issues. We conclude that in all science, and particularly where there is a highly charged social and political setting, the scientist has a responsibility for the way in which findings are disseminated and for ensuring a clear public understanding of the limitations of the work.
