An Evolutionary Perspective on Goal Seeking and Escalation of Commitment
Maximizing the probability of bypassing an aspiration level, and taking increasing risks to recover previous losses are well-documented behavioral tendencies. They are compatible with individual utility functions that are S-shaped, as suggested in Prospect Theory (Kahneman and Tversky 1979). We explore evolutionary foundations for such preferences. Idiosyncratic innovative activity, while individually risky, enhances the fitness of society because it provides hedging against aggregate disasters that might occur if everybody had pursued the same course of action.
