Abstract

Humans show a natural tendency to discount bad news while in- corporating good news into beliefs (the “good news–bad news effect”), an effect that may help explain seemingly irrational risk taking. Understanding how this bias develops with age is impor- tant because adolescents are prone to engage in risky behavior; thus, educating them about danger is crucial. We reveal a striking valence-dependent asymmetry in how belief updating develops with age. In the ages tested (9–26 y), younger age was associated with inaccurate updating of beliefs in response to undesirable in- formation regarding vulnerability. In contrast, the ability to up- date beliefs accurately in response to desirable information remained relatively stable with age. This asymmetry was medi- ated by adequate computational use of positive but not negative estimation errors to alter beliefs. The results are important for understanding how belief formation develops and might help ex- plain why adolescents do not respond adequately to warnings.
