The U.S. Army used its "General Technical" (G.T. score), an I.Q. test, as its standard for measuring intelligence. One needed above a certain score to be considered for Officer's Candidate School and some of the other schools like Neuro-psychiatric Technician School, for instance. I am not saying that I.Q. tests are the true measure of intelligence, but that they have become the default system for measuring intelligence...whether YOU accept the I.Q. test as a true measure or not.

Anyone who states that they are a Trump supporter, I immediately measure them as having a very low intelligence.

I don't. Its to varied a subject to be singularly quantifiable.

You have posed an interesting question and the first word the springs to mind is context, in what context? For example, you can take someone from the Amazon Jungle and someone who is a graduate in philosophy and give them a 'standard' intelligence test. The philosophy graduate will probably excel whereas the person from the Amazon Jungle will probably fail miserably. However, put the philosophy graduate in the middle of the Amazon Jungle and see what happens.

I heard a story about a leading Prime Number specialist who lived all his life with his mother until she died and then he moved into his sister's house. The first night in his sister's house he knocked loudly on her bedroom door at 02:30 and she came running out thinking that the house was on fire. He asked her, 'how do you open the fridge?'

I wonder if the word intelligence is stripped of it's emotive connotations would a more accurate definition emerge? However, it still seems to me to be a matter of context, therefore, I will quote a late friend who was an author: "intelligence is the ability to make appropriate value judgments in all circumstances."

Personally? I try to take into account every separate type of intelligence. A lot of us are technically geniuses in several areas and idiots in several others or vice versa. Mechanical smarts, street smarts, nature smarts, book learnin, emotional intelligence of connecting/reading people one on one, and societal intelligence of doing the same with large groups. Spacial intelligence, verbal intelligence, math and boolean logic intelligence, tech intelligence. How you use all those forms of intelligence and whether you put in the effort to train them individually and see how they work together makes a big impact on overall intelligence.

If I see that someone has a high rate of neuroplasticity and can adapt their intelligence to several different kinds of problems, I consider them a genius. People who continue reading and learning all their lives because they can't get enough, also probably worthy of being called a genius. People like Jimi Hendrix who are considered the pinnacle of their field but who will carry tape recorders to even a shitty bands show to remind us all theres always something you can learn, even from a bad show. An artistic genius is the person who is able to act most like themselves no matter who's watching, and an economic genius is the person who can get paid for it.

First you have to define intelligence, and if you can do that then you are very intelligent indeed.

Although many have challenged I.Q. tests as the true measure of intelligence, I.Q. is the default and universally used measure.
