Barrier two, duration neglect
Barrier two, duration neglect. Factors that are more important thjan duration in positive and negative emotions are the intensity of the peak positive or negative emotion, and how the experience ends.

In the book
The second fault is in the logbook itself, because that remembering self is a careless clerk. It barely notices how long a good or bad stretch actually lasted — a bias called duration neglect — and it judges a whole experience almost entirely by its peak and its ending, quietly discarding the rest. So the story you carry of your own past is not the past; it is a highlight reel edited by an unreliable narrator. — The Instruments (Awareness/Perception/Expectations)
