      abstract     = {People are motivated to adopt the most favorable beliefs
                      about their future because positive beliefs are experienced
                      as rewarding. However, it is so far inconclusive whether
                      brain regions known to represent reward values are involved
                      in the generation of optimistically biased belief updates.
                      To address this question, we investigated neural correlates
                      of belief updates that result in relatively better future
                      outlooks, and therefore imply a positive subjective value of
                      the judgment outcome. Participants estimated the probability
                      of experiencing different adverse future events. After being
                      provided with population base rates of these events, they
                      had the opportunity to update their initial estimates.
                      Participants made judgments concerning themselves or a
                      similar other, and were confronted with desirable or
                      undesirable base rates (i.e., lower or higher than their
                      initial estimates).Belief updates were smaller following
                      undesirable than desirable information, and this optimism
                      bias was stronger for judgments regarding oneself than
                      others. During updating, the positive value of self-related
                      updates was reflected by neural activity in the subgenual
                      ventromedial prefrontal cortex (vmPFC) that increased both
                      with increasing sizes of favorable updates, and with
                      decreasing sizes of unfavorable updates. During the
                      processing of self-related undesirable base rates,
                      increasing activity in a network including the dorsomedial
                      PFC, hippocampus, thalamus and ventral striatum predicted
                      decreasing update sizes.Thus, key regions of the neural
                      reward circuitry contributed to the generation of
                      optimistically biased self-referential belief updates. While
                      the vmPFC tracked subjective values of belief updates, a
                      network including the ventral striatum was involved in
                      neglecting information calling for unfavorable updates.},
