So they are employed (consulted?), or they are the primary creators, counters, and calculators of this test?
All the Gallup guys that go on TV to discuss the tests are high level math guys. They must keep the psy op guys hidden.
All, In an organization such as the Gallup Organization they are probably employed full time maybe you should look into behavioral science research where psychologist design, conduct, and analyze studies as an example. I bet youve never heard of an I/O psychologist either, you ever watch 'office space" you remember the 2 bobs they were I/O psychologist in that case they are probably consultants although there are full time positions for this type of job as well. You ever take a questionaire as part of a job application, that was more than likely designed by a psychologist. Like I said Psychologist are employed by many different industries and organizations you probably arent aware of.
