Family historians frequently encounter ethical issues in the course of their research, and many come to recognise the moral dilemmas facing them. Common dilemmas revolve around topics such as whether family secrets should be revealed or favourite stories debunked in light of the evidence, how the privacy of living relatives can be maintained when family histories are published, if the ‘sins of the fathers’ require reparation (and how this might be possible), and to what extent is it acceptable to romanticise or ‘whitewash’ one’s ancestral story. In this paper, dilemmas such as these are discussed using the theoretical framework of psychologist Jonathan Haidt whose model of five moral ‘instincts’ includes care, fairness, loyalty, respect for authority, and sanctity. It is concluded that examining ethical issues using such a framework has the potential to stimulate empathy, reduce impulsive action, and increase the likelihood of finding creative solutions to moral dilemmas.
