I mean that by separating the pro and con arguments it becomes more difficult to trace the lines of argument and counterargument. Rebuttals are harder to follow if you have to sort through a list of bullet points to find the one that's relevant to them.
I also made the comment to test whether or not you could see my comments. You can. That probably means that I'm doing something wrong or that you're writing in some equivalent of invisible e-ink. I can't think what I might be doing wrong though. I'm not too concerned about seeing the site though, so don't worry about it.
I haven't seen any links to this on Lesswrong yet, and I just discovered it myself. It's extremely interesting, and has a lot of implications for how the way that people perceive and think of others are largely determined by their environmental context. It's also a fairly good indict of presumably common psychiatric practices, although it's also presumably outdated by now. Maybe some of you are already familiar with it, but I thought I'd mention it and post a link for those of you who aren't.
There's probably newer research on this, but I don't have time to investigate it at the moment.
