On how poor our recollection of taste can be (how context can alter it)

πŸ’Ž On how poor our recollection of taste can be (how context alters it)

It turns out that we actually have surprisingly little recollection (or awareness) of even that which we tasted only a few moments ago. In one classic demonstration of this phenomenon, known as β€˜choice blindness’, shoppers (nearly 200 of them) in a Swedish supermarket were asked whether they would like to take part in a taste test.13 Those who agreed were then given two jams to evaluate. They were similar in terms of their colour and texture (e.g., blackcurrant versus blueberry). Once the shoppers had picked their favourite, they sampled it once again and said why they had chosen it, and what exactly made it so much nicer than the other jam. The shoppers were more than happy to oblige, regaling the experimenter with tales of how it was their favourite, or that it tasted especially good spread on toast, etc.

What many of the shoppers failed to notice, though, was that the jams had been switched before they tasted their β€˜preferred’ spread the second time around. The experimenter was using double-ended jam jars in order to effect this switch unnoticed. In other words, the unsuspecting customers were justifying why they liked the spread that they had just rejected.
