Trump says he'd win an IQ competition against Rex Tillerson

"I think it's fake news, but if he did that, I guess we'll have to compare IQ tests," Trump said. "And I can tell you who is going to win."
The Binet Intelligence Scale was the first individual IQ test. It came about by the military needing a way to test "smarts" of men entering the military.
Later, the Wechsler Adult Intelligence Scale (WAIS) replaced the Binet.
"The current version of the test, the WAIS-IV, which was released in 2008, is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests comprising the Full Scale IQ. With the new WAIS-IV, the verbal/performance subscales from previous versions were removed and replaced by the index scores. The General Ability Index (GAI) was included, which consists of the Similarities, Vocabulary and Information subtests from the Verbal Comprehension Index and the Block Design, Matrix Reasoning and Visual Puzzles subtests from the Perceptual Reasoning Index. The GAI is clinically useful because it can be used as a measure of cognitive abilities that are less vulnerable to impairments of processing and working memory.
Index scores and scales
There are four index scores representing major components of intelligence:
Verbal Comprehension Index (VCI)
Perceptual Reasoning Index (PRI)
Working Memory Index (WMI)
Processing Speed Index (PSI)
Two broad scores, which can be used to summarize general intellectual abilities, can also be derived:
Full Scale IQ (FSIQ), based on the total combined performance of the VCI, PRI, WMI, and PSI
General Ability Index (GAI), based only on the six subtests that the VCI and PRI comprise."
I have given thousands of WAIS tests. Based on the vocabulary of Trump and Tillerson, Tillerson would likely outrank Trump on the Verbal Comprehension section. I think Tillerson would also rank higher on Perceptual Reasoning, Working Memory and Processing Speed. Tillerson would likely have a higher combined score IQ. This is not the first time Trump has said how smart he is, however he would never allow anyone to test him.
In general about the Wechsler: Normally, the scores of the sections are close. If a section is considerably lower than others, there may be a learning problem. This test for children edition, WISC, was and is used to suggest learning problems if one section is much lower than the rest. The child would be referred for more tests to determine if a learning disability is present and if so, what it is.
