I dealt with this issue back in April for those who are interested, but Christopher Ferguson makes some interesting points in his critique of the theory that does not let the facts get in the way. Here is a quote worth pondering:
The theory of multiple intelligences fundamentally conflates intelligence and motivation. (my emphasis) It's a fatal flaw. Motivation is certainly important, and it works alongside intelligence to produce results. However, having the raw biological machinery of intelligence is simply irreplaceable.The great mystery of motivation. Even though native intelligence is required for many cognitive tasks, without the desire to engage in them one might argue that the raw material just remains raw, unrefined and not particularly useful. Of course, this discussion is a sideshow. Let's face it, skill building is a necessary evil if one is going to get to the fun stuff and skill building is drudgery for many of us. We may as well admit that some of us are never going to be able to acquire the skill.
Still, we know some people are mechanically inclined where others aren't, but the presumption is that a physicist so inclined to get his hands dirty could fix a car if he wished to. He could learn to do it. The same is not true for one with limited "g" (the moniker for native intelligence).
We need to deal with the world as it is. As Lenny Bruce once said, "What is, is. What should be, is a lie."
