Ball player Quote by Thomas Gilovich

““When little-league baseball players are thought to be incompetent, they are only allowed to play where the ball is rarely hit (for little leaguers, in right field), and thus they have few opportunities to overcome their unfortunate reputation. The continued absence of any positive contributions can then easily be mistaken for an absence of talent rather than an absence of opportunity. This type of expectancy effect is obviously a special case of the hidden data problem described above. A perceiver’s expectation can cause him or her to behave in such a way that certain behaviors by the target person cannot be observed, making what is observed a biased and misleading indicator of what that person is like. The employers, college admissions officers, and grant review panelists discussed earlier are all potential victims of seemingly-fulfilled prophecies: Their own actions guarantee that they will rarely receive a challenge to their negative assessments of job applicants, potential students, and research proposals.””
