As a computational cognitive neuroscientist I generally regard "intelligence" and "consciousness" as ill defined and not worth investigation. Yet. Later, if we can figure out brain computations we may be able to address these word-concepts.
IQ is well defined and comes out of cognitive testing which basically says that the speed with which you can correctly answer questions can physically measure a lot of things. For IQ it is success in life based on objective ratings, originally. Later it became circular and has to do with with statistical properties of the measurement itself. But this IQ stuff is not very informative about fundamental brain computations.
More interesting computationally are things like "every noun can be a verb". Here you can see your own brain computing in interesting ways. For example, take the word "intelligence" which is a noun, and make it a verb. Like "she intellected me". See what that sentence elicits to make it be a true statement to yourself. (This may take a minute to make sense to yourself, but you can do it.) You will also be able to see what it elicits if you make it be a lie.
This is an exercise that gets at how your brain computes what "intelligence" is in your own mind.
That *is* fundamental computationally.
Otherwise IQ is just a game.
The comment about mendacity, lying, is correct at least partly. Another good measure of "intelligence" might be freedom from fallacy. On this the Wikipedia entry on fallacies is hugely interesting, computationally.

I look forward to your article on the neural circuits of intelligence. As a computational guy I do not know what a "neural circuit" is. It's more like what 100,000,000 times 3,000 batteries inside your skull are doing. Predication, truth, and lies seem more fundamental.
