Irene McGee''s exit from The Real World: Seattle in 1998, the Jurassic age of reality TV, was memorable. No more than 30 seconds after she got into her friend''s car to leave, Stephen Williams - a fellow housemate and constant source of conflict - rushed up and delivered a farewell smack to McGee''s face now known as "the slap heard ''round the world."

That clip has been replayed countless times on reality television recap shows and news broadcasts, and now lives forever on YouTube. "It was like, the highest-rated moment in cable television that year," McGee says 15 years later, seated in her Manhattan studio apartment. "That''s crazy. I''m known for being hit in the face."

Here''s another crazy thing about that moment: McGee did not leave The Real World because she had Lyme disease, as the show''s producers made it seem. She left because the entire operation was rigged. The show is set up to make people mean, to incite drama. Every season, it constructs a narrative faithful to conventional story arcs, but with all the trappings of water-cooler gossip.

The key word there was construct. Reality TV is fiction sold as nonfiction, to an audience that likes to believe both are possible simultaneously in life. It''s entertainment, in the same way Cirque du Soleil enchants and The Hunger Games enthralls. But what are we to make of unreal realness? And what does it make of its viewers? Do they, like McGee''s former housemates, mimic the medium? Do they become shallow, volatile, mean?

Building the Better Narrative

Reality TV now includes the full spectrum of Americana among its stars. The bronzed L.A. housewife who rakes in millions from her line of luxury perfume stands shoulder-to-shoulder with the Alaskan crab fisherman who spends his working hours shaking hands with death. Plot and structure may differ, but reality TV welcomes all. "The one common element in all the shows is the respect and attention given to ordinary and flawed people," says Steven Reiss, emeritus professor of psychology at Ohio State University. "It is the key value asserted by the shows."
