10. An error in a choice of a neutral position
Each human understands in due course, that he is not quite objective, and his point of view has some tendentiousness. To compensate this deviation, he can choose a certain neutral source of the information. The error consists in that the people adhering to opposite sights, will choose different neutral points, each of which will be closer to a position of the one who has chosen it. We described a similar error above when discussed results of experiences in which examinees have been warned about a possible error and did the amendment on it - and, nevertheless, all the same underestimated. Possibly, it was necessary to give the amendment not only to key parameter, but also to the amendment.
