I actually do think you need to explain how they're meaningfully different, because if this wasn't something the FO had considered prior to Freeman suggesting it, then I'd say he'd be pretty fairly called the "driver" of the experiment.
He just wants to be "right" about something. Gov used to do the same thing when he didn't have an actual point to argue and would resort to bickering about the meaning of words.
Now he and Garmel are patting each other on the back "thanking" every contrarian post each one makes haha.
Those kids in class really were the most annoying ones...but they sure did catch a lot of spelling errors made by the professor!
