TIL in a study, one group of patients were given colonoscopies. A second group were also given colonoscopies, but with 3 added minutes during which the scope wasn’t moved, so it was less painful. The second group rated their experience less negatively

  1. I’m told I can just do an annual fecal-occult-blood-sample, instead of a scoping.

    *A colonoscopy is a lot like Facebook,*

    *both are great for looking-up old friends*

  2. Do some people get scoped without anesthetic? I have had four scopes and was out until they woke me. One time tho I kind of woke up in the middle and told the doc I could feel it moving. He put me right back under in a second. Never felt any pain or discomfort.

    Now the day bf prep is a whole different pile of poop.

  3. > One of the cognitive biases in hedonic psychology discovered by Kahneman is called the peak–end rule. It affects how we remember the pleasantness or unpleasantness of experiences. It states that our overall impression of past events is determined for the most part not by the total pleasure and suffering it contained but by how it felt at its peaks and at its end.[13] For example, the memory of a painful colonoscopy is improved if the examination is extended by three minutes in which the scope is still inside but not moved anymore, resulting in a moderately uncomfortable sensation. This extended colonoscopy, despite involving more pain overall, is remembered less negatively due to the reduced pain at the end. This even increases the likelihood for the patient to return for subsequent procedures.[14] Kahneman explains this distortion in terms of the difference between two selves: the experiencing self, which is aware of pleasure and pain as they are happening, and the remembering self, which shows the aggregate pleasure and pain over an extended period of time. The distortions due to the peak–end rule happen on the level of the remembering self. Our tendency to rely on the remembering self can often lead us to pursue courses of action that are not in our best self-interest
