ASKED 154 PATIENTS
TO REPORT THEIR PAIN LEVEL
AT ONE-MINUTE INTERVALS DURING THE COLONOSCOPY.
They used a scale of 0 to 10, where 0 meant no pain at all & 10 meant intolerable pain.
After the colonoscopy was óver patients were asked to rank the test’s ‘overall pain level’
also on a scale of 0 to 10. We might have expected the overall ranking to reflect the minute-by-minute
reports, that is, the longer the colonoscopy lasted, and the more pain the patient experienced, the higher
the overall pain level? But the actual results were different! Just as in the cold-water experiment, the overall
pain level neglected duration and instead reflected only the peak-end rule. One colonoscopy lasted 8 minutes,
and at the worst moment the patient reported a level 8 pain, and in the last minute he reported a level 7 pain.
After the test was over this patient ranked his overall pain level at 7.5. Another colonoscopy lasted 24 minutes.
This time too peak pain was at level 8, but in the very last minute of the test, the patient reported a level 1 pain.
This patient ranked his overall pain level at only 4.5. The fact that his colonoscopy lasted three times longer, and
that he consequently suffered far more pain on aggregate, did not affect his memory at all. The narrating self
doesn’t aggregate experiences - it averages them. So whàt dó the patients prefer: to have a short & sharp
colonoscopy, or a long & careful one? There isn’t a single answer to this question, because the patient has
at least two different selves and they have different interests. If you ask the experiencing self, it would
probably choose a short colonoscopy. But if you ask the narrating self it would prefer a long colonosco-
py because it remembers only the average between the worst moment & the last moment. Indeed,
from the viewpoint of the narrating self, the doctor should add a few completely superfluous minu-
tes of dull aches at the very end of the test, because it would make the entire memory far less
traumatic. Pediatricians know this trick well.
So do veterinarians.
