Recount of a couple of experiments (including the well-known "Pringle" test) showing how sound influences our perception of flavour.

Dark side of cognitive illusions explored in bias research

Dark side of cognitive illusions explored in bias research | The brain and illusions | Scoop.it

A cognitive bias, the “illusion of causality,” has been explored by a joint team of scientists who found that the bias isn’t limited to false beliefs about whatever was originally learned; later on, the bias can prevent new information from being learned — even when the original information is false and the newer information is true.

Gerald Carey's insight:

A summary of some studies in this area focussing on the efficacy of drug taking.
