Probability weighting

Webb13 juni 2024 · In this study, we investigate whether self-distancing can reduce the probability-weighting biases. Self-distancing refers to individuals' cognitive strategy of assuming a third-person perspective to psychologically remove themselves from the events that happen to them ( Kross et al., 2005; Kross and Ayduk, 2024 ).
