Some of us want to play in the mud but not feel dirty afterward. That's why TV producers have started adding feel-good elements to their reality shows. ABC's ''Extreme Makeover: Home Edition" is the great giant of guilt-free reality TV; rather than turning unscripted drama into a mean-spirited bullfight, it makes it into a warm communal barn raising. Rather than taxing our consciences, it qualifies as a moral write-off.
ABC's ''The Scholar," tonight at 8 on Channel 5, is the philanthropic cousin of MTV's ''The Real World." It's about 10 teens living together in a house, but it's built on a positive message about higher education. The roommates aren't just soap opera players; they're brainiacs competing against one another to win a much-needed $250,000 college scholarship. Sure, ''The Scholar" does rely on interpersonal drama, with a requisite villain; but it also celebrates the value of intelligence and clear thinking. And it will give at least one of its players a chance, as reality hosts like to put it, ''to reach his or her dream."
