abstract = {People learn more from new information when it leads to
favorable future outlooks and thus can maintain optimism
despite conflicting evidence. In two studies (N = 20 and
26), we investigated whether this optimism bias in belief
updating is self-specific by modifying a recently introduced
learning paradigm. In each trial, participants had to
estimate the probability of experiencing a negative future
event, were then presented with the population base rate of
that event, and were subsequently asked for a second,
updated estimation. In half of the 88 trials with varying
events, estimations were made for oneself, in the other half
for a similar other. We tested whether the updates
(differences between the first and second estimates)
following undesirable base rate were lower than those
following desirable base rates, and whether this difference
was greater for self relative to other. In both studies, the
overall results support the presence of a self-specific
optimism bias in belief updating. However, taking into
account trait optimism (TO) as a moderator variable revealed
that this was the case only in participants with high TO,
whereas those with low TO showed optimistic belief updating
for both self and other. In Study 2, we additionally
controlled for possible misclassifications of base rate
desirability. Taken together, the optimism bias in belief
updating was demonstrated by a selective neglect of
unfavorable information. A self-specific influence of this
bias in individuals with high TO may ultimately cause the
impression of a more positive future outlook relative to
others},
