I have read Steve Biddulph, and a few other authors / studies about boys. I listen to Richard Reeves, again illuminating.
One really interesting one was by a NZ woman (Celia Lashlie - He'll Be Ok), who'd worked in prisons / young offenders institutions for years, and then became a single to mum to a boy. She wanted to understand how these young men were going so far off the rails, in such great numbers. NZ has a really big problem with domestic, sexual and gang-related violence, the huge majority of it perpetuated by males. She went and spoke directly with hundreds of teenage boys and young men, learning what's going on in their crazy testosterone-addled heads, and who they actually listen to or take instruction from in those years (clue: it's not mum or female teachers).
What I picked up from this reading was just how completely different the world of boys is from that of girls. How they grow up, where their instincts take them, the hormonal and other internal drivers that are influencing them. I grew up with a sister, no brothers, and it was a total revelation to me. The biological reality of their physical nature, all that strength and muscle and testosterone. The point where the hormones really kick in, and they turn their back on 'mum' and gravitate towards their peers and other boys in the hierarchy. That's when they need strong, good, MALE role models to show them how to be good men. In caveman times, that's when the boys would be sent off to learn to hunt and fight.
And what do we do? Stick them in schools, staffed overhelmingly by females, make them sit still, and memorise and concentrate and be 'nice' and 'kind' all day. Being 'nice' is not how boys achieve status - and status matters more than anything at that stage. That's how they are made, that's how humans evolved, that drive is part of what pushed us forward and made us so successful as a species.
I agree with Steve Biddulph and Richard Reeves that the whole word of education - which kids are put into for years and years - has become overwhelmingly feminised. So I really don't see how yet more school classes, delivered by female teachers, in a conventional school setting, is going to make a blind bit of difference to the boys that need to hear this. They can learn to be respectful, kind, considerate men - but they need teachers and lessons that speak directly to them.
