Major life events can have a huge impact on people's emotions for a very long time but the intensity of that emotion tends to decrease with time, a phenomenon known as "emotional evanescence". When making forecasts, forecasters often overlook this phenomenon. Psychologists have suggested that emotion does not decay over time predictably like radioactive isotopes but that the mediating factors are more complex. People have psychological processes that help dampen the emotion. Psychologists have proposed that surprising, unexpected, or unlikely events cause more intense emotional reaction. Research suggests that people are unhappy with randomness and chaos and that they automatically think of ways to make sense of an event when it is surprising or unexpected. This is related to immune neglect in that when these unwanted acts of randomness occur people become upset and try to find meaning or to cope with the event. The way that people try to make sense of the situation can be considered a coping strategy made by the body. This idea differs from immune neglect due to the fact that this is more of momentary idea. Immune neglect tries to cope with the event before it even happens.
