On another forum I occasionally visit it appears to be accepted that private school children have better manners, more self confidence, present themselves better and are generally more sorted than state school children - including those at state selective schools.
I have been thoroughly told off for suggesting IF this is true it might in large part be due to the fact that private school children are drawn from the more privileged end of society where a sense of self-worth and "entitlement" is seen as part of their birth-right. And that these children would grow up with those attributes more or less regardless of what school they went to.
(I say more or less because obviously they would probably get it knocked out of them at one of the failing inner-city schools full of knives, drugs and gangs so beloved of the Daily Mail).
And I think he reason these children are more noticable at private schools is that there isn't the stratum of troubles, disadvantaged children whose backgrounds make it very difficult to have high self esteem and self-confidence.
So, nature or nurture?
