As someone who played 1e in 1981 all the way to 2012 as my preferred edition (and still do occasionally) with hundreds of players, I have not seen this. Can you cite some references to this? IME, if you had a character with a low INT and didn't role-play it that way, it was called out by both DM and players. What is your experience playing 1e in the 70s and 80s?When the rules say your character is trash at an activity, players weaseled around the rules to avoid using them. Refer to all those eloquent and brilliant 1st edition characters with bad Int and Cha scores. "Skilled play" at it's finest.
