Whom would you rather help: An acquaintance not responsible for her plight or a responsible sibling?

When 2 persons-an acquaintance who could not have avoided a problem and a close relative who is responsible for her own plight-ask for help, attribution theory and sociobiology conflict about who will receive help. Attribution theorists assume that the nonresponsible acquaintance will be supported, but sociobiologists argue that the responsible sibling will receive help. The authors tested the hypothesis that characteristics of the situation affect which theory better predicts help giving. The results confirmed that in situations that do not affect life and death, a nonresponsible acquaintance would receive more help than a responsible sibling. But in life-or-death situations, inasmuch as the reproductive fitness of the person in need is in danger, a responsible sibling Would be supported more than a nonresponsible acquaintance.
