Why did some organizations abandon the use of psychological tests in the 1920s despite their popularity?
Psychology of testing had its own win in the war- the victory of acceptance by public. Millions of schoolchildren, employees and applicants for college had to face tests batteries, the observation for which would have determined the development in their lives.
By the year of initial 1920s, about 4 million tests of intelligence were being bought each year, majorly for utilization in the schools. Binet-Stanford of Terman was sold over for 50,000 copies in the year of 1923.
The system for public education in Unites states was identified around the ideology of quotient of intelligence and score of IQ tuned into the most significant criterion for the placement of students and their advancement.
To lend scientific and authority credibility to their enterprise which was fledging, testers of intelligence had accepted terminology from earlier disciplines of engineering and medicine.
Their aim was to encourage people that psychology was not only scientific, essential and legitimate as the more developed sciences. Psychologists considered the people as subjects who were tested and not as the patients.
Tests were comparable to thermometers, which were provided to physicians only during that time. No one with improper training was allowed to make use of thermometer, an allegation also put on tests of psychology.
Tests were advocated as machines of X-Ray which allowed psychologists to look within the mind and to understand the mechanism of mind of the patients. The more they seemed to be doctors, the more amenable public became to accredit them the same status.
