Emotional forecasting!

"Emotional forecasting is one element that is unique to humans. As a species, we alone are emotional time travellers. Only humans engage in mentally fast forwarding to imagine future events and how we will feel and act during those events. Given the importance of emotions on decision-making, it is perhaps surprising to find that we are really very poor at emotional forecasting. In general, people in a cold (unemotional) state tend to overestimate the influence of emotional situations on the intensity and duration of their feelings (impact bias).
However, people also underestimate the influence of emotional situations on their choices and preferences (empathy gaps)."
