I’d say the shipwreck data reinforces it: in the circumstances where heroism is least observable and where death is most likely (reducing the potential reward and increasing the incurred risk), we see less peacocking. If the relationship ran the inverse direction—the more the reward and the less the risk, the less risk-taking—that’d be pretty strange and hard to reconcile with the Baumeister paradigm.
