Psychologists found out that on pairs, made the decision, it is almost impossible to affect
Psychologists from Pensilvansky University defined that the person, making decisions alone, easier perceives counterarguments whereas the decisions which are accepted by pair, it is almost impossible to change.
The site of Association of psychological sciences of the USA tells about the work which has been carried out by Julia Minson (Julia A. Minson) and Jennifer Muller (Jennifer S. Mueller) in which more than 250 volunteers took part. Participants needed to analyse a situation in the country and approximately to estimate 9 indicators concerning geography, a demographic and economic situation of the USA. Some volunteers answered questions independently, others after discussion with the partner.
After all answers were received, them showed to all participants and allowed to correct the conclusions. Also people were offered to estimate, as far as they are sure of the assumptions. For motivation, the sum of 30 dollars from which the percent of discrepancy of the answer of the examinee with the correct was subtracted was offered volunteers.
The result of experiment showed that "singles" changed the decision on the basis of arguments of other participants more often, and as a result were closer to the right answer. Pairs, though were initially more exact in the conclusions, but subsequently the decision did not change, being unduly sure of the and as a result, lost.
So, psychologists drew a conclusion that on pairs, made any decision, it is almost impossible to affect even the most reasonable arguments.
