Nope, there is merely a level of possibility with intellect. For instance he does not have convient processing plants to build the high tech material necessary for major projects.
He has not the time to do the research to close up the missing layers of knowledge, he can make darn good guesses though.
His int bonus on skills is quite useless without some certain feats....
In effect, he is born into a world that is in itself limited, in knowledge, resources, etc... All the intelligence in the world is no good if you don't have the knowlege to back it up, and he can only get 4 ranks of any skill....
That is interesting, I don't consider intellect body control. That is why it does not add to dodge. So despite the fact that he knows exactly where how, and what that sword will do to him, he can't move out of the way.
Further, giving him such special abilities is outside of the standard D&D system, sure you can invent them, but THOSE would be what determine the CR not the ability score.
Nope, he doesn't know exacly how everyone else is breathing, because he cannot observe them. Remember 'wisdom' is the observation score.
It is perfectly possible to bluff this guy. His sense motive is only +4. Boom a 10th level rogue tricks him into thinking he is friendly (BLUFF), knife in the back.
His intelligence does not apply to people, heck he may walk in broad daylight without protection all the time. He isn't afterall WISE.
The realistic effects are even more limited basically as intelligence is described he would:
Remember everything
Learn any skill instantly
Reason perfectly.
Unfortunately, his reasoning would be just as flawed without the appropriate knowledge, sure if presented the knowledge he would immediatly understand it and all its implications, possibly those he hasn't even seen yet.
He has no better common sense, intuition, or perception than the common man.
