Is it me or are writers very inconsistent when it comes to Superman's intellect, John Bryne made Superman have everything in the fortress because of the eradicator thus making Superman not create most of the stuff on his own in the fortress. Yeah bryne had a more less intelligent Superman. Grant Morrison portrays superman has a genius cause in his mind its kinda stupid and illogical that his parents where the most intelligent scientist on krypton and how that was never even passed on what so ever seems stupid to him. I mean Grant takes it to a level that Superman and Lex are intellectually equal to each other ( not to Brainiac) but lex is a better strategist then Clark
Some writers do this also make superman stupid when he is fighting his foes outside the fortress in Metropolis and Lex smarter then him then out of nowhere in the fortress he can build portals to other dimensions like Lex Luthor could. Earth One books Superman is kinda a Genius but doesn't want to show it, heck maybe superman is like that, but it seems very odd that writers don't make superman use his head but when he is in the fortress that's where superman's brain goes crazy and starts building crazy things. I like Grant Morrison's portrayal of Superman actually being a genius and his explanation for it.
I do like that Grant showed Superman being a Genius in science but he s not a great tactical person that i can live with.
