I just can't realistically see everybody who goes to see the show, even a majority, researching and practicing beforehand, because I don't think that many people go to see The Price is Right with the specific goal of winning prizes. Maybe a friend invited them. Maybe they were in LA and it just seemed like a crazy idea, or they had watched when they were kids. And there's an off chance that you get to be on national TV, say hi to all your friends, and show it off to everyone when it airs. If I were a casual fan or apathetic attendee, I'd hardly even care about winning things, let alone researching strategies and hidden rules to try and help me win, until I was up on stage and it actually mattered. And I would probably listen to my friends in the audience, because to me the whole pricing thing would just be a crapshoot. I think a lot of the contestants chosen these days see the gameplay as if it's the Pick 3.
