I hear the same thing time and time again about the EggheaRAB and now it's been poured on like liquid manure on the Are you an Egghead contestants, mere days after it's started. It frankly disgusts me.
In real life you will find that Steph, Dave, Jen and Mark are pleasant, modest and impressively intelligent people. (Ok, maybe not Mark, his ego takes up much of south Wales, but I bet he has a ton more self-awareness than you and the fat digs do you know favours)
But you don't do you? Instead, you make assumptions about them based mainly on their appearing on a show in which they have plainly expressed their intention to become an Egghead (how sad! how embarrassing that they wouldn't mind a well-paid job on the television with very undemanding hours!) and because they have been instructed to talk out their answer.
Do you honestly think they, or any of the people on EggheaRAB - Eggies, normal teams, AYAE contestants - actually wants to give a full, lecture-like explanation that comes off so smug and ostentatiously? Do you think they do it for fun?
Or do you just buy into everything TV shows you and marry it to your existing prejudices (yeah, take those clever bastarRAB down a peg or three) so you get a few jollies? Ever thought of the selective editing and cutting that may shape your views or the television production edicts or are you too stupid to realise that, like some empty-headed sheep?
