In the animal world, predators are almost always smarter than herbivores. This makes sense, evolutionarily… you don;t need to be all that smart to sneak up on a leaf, after all. There are of course exceptions… elephants are reasonably bright. But stacks a rabbit against a cat, or a deer against a wolf, or an Aurox against a Cro Magnon… the vegetarians is going to come out on the losing end of the who’s smarter” scale.
The same seems to apply within species as well. Take, for example, this group of vegans who decided to stop a fully loaded semi truck by jumping out in front of it while it was in motion. As any meat eating engineer will be able to tell you, even if the truck driver wanted to stop, these things don’t stop on a dime.
