I'd say that's probably a good list, David.

However, I'd be inclined to flip #1 and #2. I actually think Doom might be just a hair smarter than Reed based on pure intellect (Reed has even admitted that a couple of Doom's inventions are beyond what he could do). But Doom's fatal flaw is always his ego - Reed has the humility to admit he might be wrong, whereas Doom's supreme self-confidence usually proves to be his undoing.

And while Bruce Banner undoubtedly is a smart guy, he rarely gets the chance to truly show it. More often, he's living like a homeless person or running one step ahead of the law. If we are talking actual achievement, versus intellectual potential, I might be inclined to put someone else in that spot.

It's kind of a preposterous premice when you try to compare people who are 'experts' in their fields like Dr. Leonard Samson, Dr. Bruce Banner and Matt Murdock.  Who's to say a geat lawyer like Murdock is or isn't smarter than a great Psychiatrist?

That being said there are so many criminal masterminds (like the Mad Thinker, the High Evolutionary and the Leader) it's hard to come up with a definitive list.

I guess a list of the top 7 (off the top of my head) would probably have to include Richards, Pym, Von Doom, Stark, Banner, the Leader and the High Evolutionary.

Still, introducing a character as the 'seventh smartest person in the world' is a little ridiculous IMO, but arguing over who the seven smartest are is kid of fun...

I concur with Bruce.  That's a great list but I would flip one and two.  However, I disagree with Bruce's comment about Dr. Banner.  I think he would be #7 on that list.
