In the face of the researchers obtained data informing that the assessment made by them are wrong, the students simply be changed (improved). Were clearly less inclined to change their assessment of students who have enrolled their assessment blue stairway. Although their involvement was purely private in nature (only they knew the record of their valuations), but the mere fact that his assessment of enrolled, to some extent already urged their support. Finally, the most consistent were students whose initial assessments were made public. They simply refused to change them, even in the face of data suggesting their falsity.
