Excuses, Ecxuses

It's because they're stupid, says Brit educator:

Dyslexia is a social fig leaf used by middle-class parents who fear their children will be labelled as low achievers, a professor has claimed.

Julian Elliott, a leading educational psychologist at Durham University, says he has found no evidence to identify dyslexia as a medical condition after more than 30 years of research.
"There is a huge stigma attached to low intelligence," he said.

"After years of working with parents, I have seen how they don't want their child to be considered lazy, thick or stupid.

If they get called this medically diagnosed term, dyslexic, then it is a signal to all that it's not to do with intelligence."
