How do reality show producers mold a cast member into a 'character'?

That is another conception about reality TV that people give us way too much credit for, and that is molding characters. First of all, in casting a person, who that person is or is likely to become in certain situations becomes pretty clear. If somebody is going to be self-righteous or obnoxious, we will know it going in and we have every anticipation that they'll be that way when they're on the screen. The molding part I think we're given far too much credit for. A lot of that comes from people saying the producers edited me to look that way. Especially if they don't look good.
