I always considered that IQ tests are subjective, allowing you to reveal only one or several aspects of a personality. In the long run they fail to give you a clear picture, and if you're holding the results of a person's test in your hand, and the label says "IQ=87", what can you really say about that person, except "this test says that this person has an IQ of 87"?

No, this story will not tell you how to measure one's intelligence, instead it will provide an abstract model which tries to explain how intelligence works at a high level. I don't know how this was implemented in our brains, so don't ask, because this is not the objective of this story.The idea is that intelligence is a function of a tree's depth, width and color ;-)

An attempt to understand what is intelligence and how it can be measured. The story was posted on my previous web-site, but after it was taken down, all I have is the PDF version of the doc.

It does not pretend to be one's comprehensive guide to intelligence, it is just a set of thoughts laid down on paper and accompanied by nice pictures.
