Figure 2

Truncation selection with various payoff schemes whose means and variances are the same, using a reproduction threshold of the 50% of the population with the highest payoffs. When the risk-prone strategy’s payoffs are distributed asymmetrically around the payoff mean, there is a higher probability of receiving one of the two payoffs. This leads to a strong advantage to the risk-prone strategy, dependent on the probability of the risk-prone players’ receiving each of the possible payoffs. Panel (a) shows payoff schemes that differ in the probability of risk-prone players’ receiving the high payoff; panel (b) shows results for payoff schemes in which the probability of receiving the high payoff is near 0.5.
