I'm available for comment! (Jeez, with phrases like that, you should be a reporter.)
Agreed. I'm not very good with that, although since discovering MBTI, I'm a WHOLE LOT better.
Hm... I hadn't really thought about it... but nozflubber's comment did annoy me because I feel like there's a lot more going on in my head than people think there is. (I just don't know how to express a lot of it in words.) So maybe that's a sign that MDP's got it right. But I have a feeling that ESTJs are all going to have different answers as to what makes their thinking complex, since we don't really introspect enough to diagnose it. So I'll just ramble for a paragraph and see if it gets anywhere

:
I tend to have a lot of inner conflict in my more stressed-out moments. (I refer you all to the "iceman and the child" thread... awesome, accurate concept.) I have many convictions that end up being... well, not NAIVE, per se, but too idealistic to really work out... and those convictions are challenged all the time. The fact that we live with those challenges, and often have to make tough choices that conflict with those convictions (because there's no other option), is probably what makes people think that ESTJs are hypocrites. (And, well, we ARE, but so is everyone, in some way or another.) So, with all that conflict going on (which, presumably, doesn't happen much with INTPs, since they're so inherently realistic and logical), and with none of that conflict spoken of to the people around them, it makes sense that people might think they're kind of two-dimensional in their thinking. (After all, ESTJs are famous for making tough decisions, following through with them, and not looking back, NOT for the complicated thought processes they have to go through to get to those tough decisions.)
Now, I don't know how much of that paragraph was BS and how much of it might actually refer to other ESTJs, but... hopefully most of it is accurate.
