Rosy retrospection

A kind of memory bias, rosy retrospection refers to the finding that subjects later rate past events more positively than they had actually rated them when the event occurred.

The effect appears to be stronger with moderately pleasant events.

In one group of experiments, three groups going on different vacations were interviewed before, during and after their journeys. Most followed the pattern of initial anticipation, followed by mild disappointment. Generally, most subjects some time later reviewed the events more favorably than they actually did while experiencing them.
