The article linked at the bottom will help to clarify the matter. A wannabe pederast, Yaron Segal, had a PhD in physics and worked at MIT! They don't come any smarter than PhD physicists who work at MIT. Yet the guy got caught in a honey trap set by the Feds. Being a pervert as well as a physicist Segal tried to hook up with some adolescent girls for a weekend slumber party - and was arrested as soon as he stepped off the plane. In jail, he had time to reflect on the error of his ways and to do the calculus of thirty years in a 9x9x7 box. Realizing the solution, he killed himself. Honestly, in this day and age is there anyone who doesn't know that the Feds are all over the Internet? Especially the child predator sites? Hell, even I know these things. So, smart though Mr. Segal may have been, he was to put it politely, a dummy.
You may be smart enough, ha ha, to understand that what I really mean by "intelligence" is wisdom. Wisdom is a different concept than smartness. Smartness sees a problem and devises a solution. Wisdom sees a problem before it arises. Wisdom also sees a solution before the problem arises. Smartness is an exertion of the brain and has a limited radius. Wisdom, is of the mind and touches the infinite. Mr. Segal was a very smart guy - with a narrow field of view. Smartness sees the microscopic dots in a picture. Intelligence/wisdom sees (and gets) the picture.
