Durability Bias

Durability bias, a type of impact bias, is the amount of time in which an emotional reaction actually lasts as opposed to how long a person believes that an emotional reaction will last. Most people tend to over estimate the length of time of time an emotional reaction will have an overt effect on their psyche and mental state.

For instance, in the case of severe emotional trauma, a person might still react to that fear after many years (or even decades), even though some insensitive people might say to them,"Why don't you just get over it?" On the other end, someone who is going through a breakup may think they're going to feel horrible forever and never get over it. But as time passes, these bad feelings start to wane and most people feel better much sooner than they originally believed.
