[ 1 ] [ 2 ] It should not be confused with risk aversion , which describes the rational behavior of valuing an uncertain outcome at less than its expected value .
Women are more risk averse than men. [citation needed] One potential explanation for gender differences is that risk and ambiguity are related to cognitive and noncognitive traits on which men and women differ. Women initially respond to ambiguity much more favorably than men, but as ambiguity increases, men and women show similar marginal ...
In this context, the perplexity k indicates that there is as much uncertainty as there would be when rolling a fair k-sided die. Even if a random variable has more than k possible outcomes, the perplexity will still be k if the distribution is uniform over k outcomes and zero for the rest.

Most theoretical analyses of risky choices depict each option as a gamble that can yield various outcomes with different probabilities.
