agree with Dulra - I'm Welsh and it would be very easy for me to bring loads of things to represent that. I noticed the blonde psychologist mentioned that she associated, the English flag the one girl brought to represent her supporting England in the football, with BNP/hooligans etc. and thought that was really sad, as there aren't the same associations for the Welsh/Scottish flags, same with the idea of celebrating our patron saints days and so on.
I was also surprised that none of the white kids could think of any negative experiences they had had related to their race (note that was the question asked, not, "have you experienced racism." I had a similar discussion in my PSE lessons a few years ago and nearly all the white kids had a time they felt uncomfortable in 'black' areas, or had been called 'white slut' or similar or had been told that white girls were sluttier than other races and deserved to be raped if they went out alone/wore slutty clothes, didn't cover their hair, etc. One mentioned when she went to China and constantly had people pointing at her, taking photos of her, saying how huge her feet were, etc.
This could have led to an interesting discussion about the difference between people using your race to insult you, or being mean generally, and cultural/institutional racism. However I was a few years older (14/15) so perhaps that's why. Or perhaps some did have experiences and it was just editing.
Also surprised at the focus on the Harvard bias test which I thought had largely been discredited now.
Also thought it was interesting how the one black boy and his mother had such different experiences and expectations of the police - he felt scared of them, she was reassured by police presence etc.
However in fairness to the program makers they managed to find the some of the nicest kids in the UK! They were all really articulate and kind towards each other, without exception all really sweet.
