>>11350304I was treated and on therapy for avpd and depression disorder They are still doing IQ tests (alongside EQ - which are silly and any non-brainlet can score max on them without problem by just well... thinking and some linguistic tests) in all mental health / neurology facilities (alongside mri/pet/eeg) as a standard procedure, so no, it's purpose is not only dick-waving.
Paying for the test is stupid though.
Say two test subjects has similar background and personality traits, one with higher IQ will have more success chances.
