Moral disengagement is a process whereby the self-regulatory mechanisms that would otherwise sanction unethical conduct can be selectively disabled. The present research proposed that moral disengagement might be adopted in the endorsement of asylum seeker policies in Australia, and in order to test this, developed and validated a scale in two studies. Factor analysis demonstrated that a two-factor, 16-item structure had the best fit, and the construct validity of the scale was supported. Results provide evidence for the use of moral disengagement in the context of asylum seekers as a means of rationalizing conduct that may otherwise be sanctioned.
