Have been reading this thread like
. Noble is exactly right; I have a family member who is a TV producer making these type of reality programmes, and can assure you there'll be hours of footage of the behaviours people are saying they didn't see in these kids/parents, good and not so good, all on the cutting room floor. People really shouldn't be judging 12 yr olds (or anyone) based on a few isolated minutes in very specific situations.
I find it very uncomfortable that people are talking about these children's 'likeability' - they've gone on TV to try to do well in an 'intelligence test', not to have the added pressure of making millions of viewers like them. I doubt any of us, trying our hardest, could do that, without any control of the editing.
