What happens if your working memory is so poor that by the time you’ve put on your opposition hat to scrutinize your original position, your brain is out of bandwidth and it forgets the details of original position, or it can’t scrutinize that position because there isn’t enough bandwidth to hold both the original idea and the counter position simultaneously? So now you’ve got a counter argument to a now forgotten original position.
Haha… Yes, I was being a bit cheeky but you’re right, in a case like this using notes is indeed the answer perhaps like Nathan Fielder in the show The Rehearsal, if you’re looking for a ridiculous and extreme example!
Just wondering.
