Choice blindness
Introspection illusion (English choice blindness ) is a phenomenon in which a person can not distinguish between actually striking differences between their intended selection and the actual result.
For example, if a test person is to choose the more attractive face from two images with faces and if the images are swapped inconspicuously for the test person while the person justifies their decision, the test person seldom notices the swap and still defends their (wrong) choice. This applies even if the person has had a long time to deal with the two faces beforehand.
The researchers Petter Johansson, Lars Hall, S. Sikström and A. Olsson from Lund University described this effect in 2005 in the journal Science .
