Megan McArdle quotes:

The Up Side of Down: Why Failing Well Is the Key to Success.

If we wanted a program to help the majority of the population, we'd offer loan guarantees to help poor people get access to reliable cars so that they could have a better shot at getting - and keeping - a well-paying job...A small amount of capital could make a much bigger difference in their lives than extra student loan relief for middle-class college kids would.

I'd also like us to encourage people to gang rush shooters, rather than following their instincts to hide; if we drilled it into young people that the correct thing to do is for everyone to instantly run at the guy with the gun, these sorts of mass shootings would be less deadly, because even a guy with a very powerful weapon can be brought down by 8-12 unarmed bodies piling on him at once.

It is a vast, and pervasive, cognitive mistake to assume that people who agree with you (or disagree) do so on the same criteria that you care about.
