A reader recently took the WAIS-IV IQ test and asked me to comment on his scores.  I’m not a professional in this field, but I do know a bit about this, so I decided to take a look.

Subject describes himself as a modestly successful 30 year-old male holding down junior leadership positions in stakeholder engagement, and even holding down decent employment during a brutal recession in Alberta, Canada.
In high school, he got As in Social Studies and English with little effort, but almost failed Grade 11 Physics with “a proportional grind”. Subject reports having little mechanical skill beyond being able to change a car tire, and is a social science grad student with minor skill at statistics.
Although I’m not a professional, during a brief email exchange, Pumpkin Person observed good executive functioning and thought organization skills, and no signs of socio-cognitive impairment, however there were very slight indicators of anxiety and obsessive compulsive traits.
Subject revealed that the biodemographic analysis predicted his overall WAIS-IV IQ quite closely.


His scores on the WAIS-IV were as follows (U.S. norms):

Vocabulary IQ 135

Similarities IQ 135*

Information IQ 125

Overall verbal reasoning: IQ 138

Matrix Reasoning: IQ 115*

Block Design:  IQ 115*

Visual Puzzles: IQ 110

Overall perceptual reasoning: IQ 116

Digit Span: IQ 130*

Arithmetic: IQ 120

Overall working memory IQ: 129

Symbol search: IQ 120

Coding: IQ 135*

Overall processing speed IQ: 130

Overall global IQ: 136

Subtests with asterisks are those subject feels might have been compromised due to his knowledge of the Wechsler subtests.  When I remove these subtests from his profile, and prorate with the remaining “uncompromised” subtests, his composite scores decline somewhat, but the pattern of strenghts and weaknesses remain:

Overall verbal reasoning: IQ 136


Overall perceptual reasoning: IQ 111


Overall working memory IQ: 122


Overall processing speed IQ: 122

Overall global IQ: 129

However it’s unclear whether subject really knew enough about said subtests to justify their removal.  Given the amount of subtest scatter, it could just be a coincidence that subject performed worse on the subtests he knew little about, so I would not necessarily recommend removing the “compromised” subtests.

Pumpkin Person’s unprofessional recommendation:

It’s hard to tell subject anything about himself that he hasn’t figured out already.

Although subject is above average in all areas measured by the WAIS-IV, he is WAY above average in verbal reasoning, and has credentials in a verbal field (social sciences), thus, he should stick to jobs requiring written and/or  oral communication, and theoretical work, and avoid jobs requiring visual or spatial practical problem solving, unless he has a passionate interest in them.  The combination of extremely high Vocabulary and Similarities suggests he might be potentially quite good at writing.

And although subject describes a minor talent for statistics, his relatively weak (though still above average) spatial abilities, combined with the fact that Arithmetic is his lowest non-visual score, suggest he should probably avoid math related fields as well, unless he has a strong interest in the subject.

Overall, subject’s IQ is in the “Extremely bright” range.  Such people typically find work in high status occupations and although it’s unlikely that even someone this bright will become a multi-millionaire, they typically earn a very comfortable living, acquiring high five figure incomes by their early 30s.
