Why can Uncertainty Cause Stress?
By Dr Liji Thomas, MD
Uncertainty about the future makes us less capable of coping with negative events when they happen. It also disables us from taking effective and efficient steps to avoid them. This negative reaction is actually a maladaptation of the intrinsic ability of the human brain to predict the future, based on knowledge and past experience.
This ability helps humans to deal with possible negative outcomes or to avoid them, and to maximize the chances of a positive outcome. A critical level of certainty seems to be required in order to achieve this kind of processing. Below this level, individuals become uncertain as to whether a desired event will happen, and to the setting of that event in time and in life situations.
