Obviously that's a bit of a provocative title. (I should have called it "How Smart is Thor?") Of course Thor's not dumb. But I feel like in a lot of stories - both his own and when he's with the Avengers - he's portrayed as someone who is brave and noble, but not always someone who thinks things through as much as some other heroes do. He's more like mythological heroes, who are clever when they need to be but prefer action to conniving.
This is, as I said, played up when he's with the Avengers (in the comics and movies), often for laughs. Steve Englehart had a good line about him being more concerned with action than reflection.
But I was wondering how Thor fans see him, and whether there are stories that play up his intelligence or cleverness instead of his strength.
I'll conclude with my favorite "Thor isn't too quick on the uptake" moment.
