From: Evolution of risk preference is determined by reproduction dynamics, life history, and population size

Figure 4

The frequency of fixation of the risk-averse strategy in a power-weighted selection scheme for a range of parameters, which give rise to convex or concave fitness functions. Qualitatively, concave functions lead to an advantage to the risk-averse strategy and convex fitness functions lead to an advantage to the risk-prone strategy, but the details of the system are important: the extent to which one strategy is preferred over the other strongly depends on the population size.
