Our memory of product experience being distorted under questioning

The questionnaire asks about the pudding. You remember the excellent lemon tart. It asks about the welcome. The receptionist’s smile returns. By the time it requests an overall score, your memory has been furnished, lit and shown around like a flat on viewing day. That score will be filed as though the survey simply retrieved it.

This is one of research’s more elegant bits of self-deception. Memory is rebuilt from what happens to be accessible now, and the question changes what becomes accessible. Ask after the fire alarm and the hotel is one thing. Ask after the complimentary breakfast and it is another. List five attractive features before “overall satisfaction” and you have not merely measured a judgement; you have supplied its shopping list. People then provide reasons with impressive fluency. Fluency is reassuring and commercially dangerous. A confident account of why something was bought may contain genuine recollection, a theory invented on the spot and language borrowed from the question. The decimal places added later cannot separate them.

Send the hotel survey after breakfast and the memory smells of coffee. Send it during the fire alarm and it has bare feet on cold pavement. Send it six months later and both incidents may have collapsed into a general feeling that the place was “quite nice”. None of those memories is fake. None is the untouched experience either. The survey result includes the moment of asking, whether or not the methodology page has room to admit it.
