This is compounded by a bigger issue in my opinion - which is that a lot of people actively disliking intelligence and balk at encouraging family to be ‘elite’ or ‘above’
How often do you hear it? Clever clogs, swot, teachers pet, suck up, airs and graces, too clever by half, thinks their better than others, smarty pants etc. etc.
So many people think clever people are out to trick them, con them, take control of the world with their ‘schemes’ or, worst of all, look down on them. Demonstrable proof, evidence and scientific basis are all dirty words/thoughts.
I'm not saying everyone should doff their caps or just defer without question. But there was a time when the less educated at least acknowledged the fact the educated knew things and that education was to be valued and strived for. Almost every study ever done equates education with better outcomes, most especially for women.
Children reflect their parents 90% of the time, if they make no effort, their parents don’t encourage them too, if they think it’s not important, their parents have in some way demonstrated that belief to them; and you can’t suggest self improvement to the parents - that would be you insulting them and looking down, rather than a perfectly useful, helpful suggestion.
Ultimately, I’m saying a lot of parents need to take a long hard look at themselves as to why their children don’t / won’t try in schools.
They don’t want to take that look.
