I found the post regarding the cheat.txt and how to change the happiness, confidence, muscles, etc. In that post, it says you can also change the I.Q. and Culture, but it doesn’t seem to work for me. Whether I put it at 0.4 or 1.0, my characters always start out at 25%.
Is this hard coded into the game and you cannot change that by using either the cheat.txt or any of the csv files? I also tried changing the Default for I.Q. and Culture from 25 to 40 in the csv files, but that made no difference as well.
Hoping that someone, anyone sees this question and responds. This will be my third question and I’ve had no responses to any of them so far. 
Seems like no one plays this anymore. I put my two other posts under the General category though, so maybe no one saw them.
