Who’s Smarter – Tony Stark or Bruce Wayne?
Who Is Smarter: Batman or Iron Man?
Last but not least, Batman had to and did come up with a contingency plan to defeat every other member of the Justice League (not just the villains they’ve been dealing with), which required a lot of thinking and planning. Stark never had to, nor did he do that (he was even beaten to a pulp by Captain America, who is not nearly as smart as him).
His knowledge of other fields is either not big or has not been explored in the comics, so we cannot really state that it exists. As for Bruce Wayne, he not only knows a lot more than Stark when other fields are concerned, he also has a decent knowledge of different sciences, including physics and mechanics. Although Stark knows more in these fields than Wayne, when comparing the sum of their knowledge – Wayne is the clear winner.
With this, we conclude our argumentation. It seems that both Tony Stark and Bruce Wayne win in one aspect – Stark is a better creator, while Batman is a better thinker. Which is better? It’s impossible to say, because that would be like comparing apples and oranges – someone just likes oranges more, while other people prefer apples.
Still, most of that is pretty simple when compared to Stark’s technology. On the other hand, Batman does have similarly advanced technology, but most of it was designed and built by Wayne Enterprises, i.e., Lucius Fox, who is Batman’s close associate and knows his true identity. In this aspect, Tony Stark does have the upper hand, but he also has the necessary education (he is an engineer) so it should not come as a surprise to anyone.
As far as their knowledge goes, Tony Stark is much more “limited” in that aspect. He knows physics and mechanics, but outside of that – he doesn’t really know that much. This doesn’t mean he’s ignorant – on the contrary – but the extent of his knowledge is far more limited when compared to Bruce Wayne’s.
