I've been thinking about this with Brexit, Trump and the tories in this country, why people are so dogmatic. Yes, there's the jingo-morons, the racists and the grifters that prey on both, they're beyond hope largely, but there are plenty in govt., business and the wider public who will fully understand the damage these doomed strategies and policies are inflicting. I think the problem for these people is, they think, as soon as you put your hands up and say 'yep, I was wrong', it will call into question every decision you've made, and will make, whereas for most rational actors we know the opposite is the case, but its not an unreasonable fear.
