Risk Aversion. This chapter looks at a basic concept behind modeling individual preferences in the face of risk. As with any social science, we of course are fallible and susceptible to second-guessing in our theories.

1 Ιαν 2023 · The relationship between cognitive ability and risk aversion is positive when risk aversion was measured using MPL, while increasingly negative when assessed with either EGRT or CT. Moreover, the relationship moved in the negative direction when the payoff of the safer choice was kept constant.
25 Οκτ 2018 · Most research on risk aversion in behavioral science with human subjects has focused on a component of risk aversion that does not adapt itself to context. More recently, studies have explored risk aversion adaptation to changing circumstances in sequential decision-making tasks.
Results indicate that there exists a weak, but significant negative relationship between cognitive ability and risk aversion in the domain of gains. However, no relationship was observed in the mixed domain or in the domain of losses.
