Beslissingen, psychologisch: het staafjes experiment
|
17 dec.2007 |
Het staafjes experiment is ooit eens uitgevoerd gezien op televisie door de redactie, die daarvan stijl achterover sloeg, omdat
zij zich niet kon
voorstellen dat iemand ooit een ander antwoord zou geven dan het in eigen ogen
correcte - dit
onder het aloude Rotterdamse motto: "Als honderd man in de Maas springen, spring
je er toch ook niet achter aan?" In het populaire-wetenschap blad Triv (dec.
2007) kwam eindelijk de bron boven water - onderstaand de Wikipedia versie:
Van: Wikipedia.org:
Asch conformity experiments
The
Asch conformity experiments, which were published in 1953, were a series of
studies that starkly demonstrated the power of conformity in groups. These are
also known as the "Asch Paradigm".
One of the pairs of cards used in the experiment. The card on
the left has the reference line and the one on the right shows the three
comparison lines. Experiments led by Solomon Asch asked students to participate
in a "vision test." In reality, all but one of the participants were
confederates of the experimenter, and the study was really about how the
remaining student would react to the confederates' behavior.
The participants — the real subject and the confederates —
were all seated in a classroom where they were told to announce out loud their
judgment of the length of several lines drawn on a series of displays. They were
asked which line was longer than the other, which were the same length, etc. The
confederates had been prearranged to all give an incorrect answer to the tests.
While most subjects answered correctly, many showed extreme
discomfort, and a high proportion (32%) conformed to the erroneous majority view
of the others in the room when there were at least three confederates present,
even when the majority said that two lines different in length by several inches
were the same length. When the confederates were not unanimous in their judgment,
subjects were much more likely to defect than when the confederates all agreed.
Control subjects with no exposure to a majority view had no trouble giving the
correct answer. ...
Red.: Merk op dat de originele vorm van het experiment anders
is dan de door de redactie geziene en gebruikte, en ietwat minder doorslaggevend -
in de nieuwe vorm kozen de mensen ook daadwerkelijk het foute staafje..
