Patients demanding placebo like vitamin shots or antibiotics is an old problem (or technique, depending on how you look at it). For that matter, many doctors are regularly prescribing people stimulants or opioids because patients are asking for them - instead of turning down their money and/or making them unhappy.

I agree with you and like the example, but I wanted to provide feedback that this example is confusing in its relation to the current topic.

This example is excellent for cognitive bias!!!

We know that we should only trust double-blind controlled randomised trials. This surgery hadn't had that trial, thus it shouldn't have been trusted, yet it was. And the reasons it was trusted are just biases.
