36704YuNoHaHoDe AbHoT343 The Main HUMAN Experiment
{Q&@ CONTINUED:}
FOR EXAMPLE, IN EVALUATING THE SHORT PART
OF THE COLD-WATER EXPERIMENT OUR NARRATING SELF CALCULATES
the average between the worst part (the water was very cold) & the last moment (the water was still very cold)
& concludes that 'the water was very cold'? Our narrating self does the same thing with the long part of the experiment!
It finds the average between the worst part (the water was very cold) & the last moment (the water was not quite so cold)
& concludes that 'the water was somewhat warmer'! Crucially, the narrating self is duration-blind, giving no importance
to the differing lengths of the two parts? So when it has a choice between the two, it prefers to repeat the long part,
the one in which 'the water was somewhat warmer'.
EVERY TIME THE NARRATING SELF EVALUATES OUR EXPERIENCES, IT DISCOUNTS THEIR DURATION
& adopts the 'peak-end rule' - IT REMEMBERS ONLY THE PEAK MOMENT & the ènd moment, & assesses the whole
experience according to their average. THIS HÀS FAR-REACHING IMPACT ON ALL OUR PRACTICAL DECISIONS?!!
KAHNEMAN began investigating the experiencing self & the narrating self in the early 1990s when, together with
Donald Redelmeier of the University of Toronto, he studied colonoscopy patients.
In colonoscopy tests a tiny camera is inserted into the intestines through the anus in order to diagnose
various bowel diseases. It is nòt a very pleasant experience! Doctors wanted to know hòw to perform this procedure
in the least painful way? Should they hasten the colonoscopy & cause patients more distress for a shorter duration,
OR SHOULD THEY WORK MORE SLOWLY
AND CAREFULLY?
