The analytic utility of distinguishing fighting from dying.

Fighting and dying, or what Whitehouse calls "out-group hostility" and "extreme self-sacrifice," are not conceptually overlapping, but in fact are highly distinguishable, both theoretically and empirically. I present empirical evidence from a reanalysis of Ginges et al. (2009, Study 4), demonstrating the potentially inverse relationship between "parochial hostility" - fighting and "sacrificial altruism" - "and" dying.
