I reject the idea that it is my duty to have political opinions.

I reject that idea as well. I even have some questions about the basic rationality of having political opinions.

But I do have political opinions, and a lot of other people do as well, so I'm asking.

if I had a magic button that could make one small change to the government, I would require all MPs to read Yvain's consequentialism FAQ

I've got a briefer one. Ask Thomas Sowell's 3 questions. Compared to what? At what cost? What evidence do you have?

Or Dan's 3 Fair Questions: When you say "It is unfair", what does "It" refer to, who are all the people effected by your solution to this unfairness, and how is your solution fair to everyone effected?

possibly something to kick some statistical sense into them.

Dare to dream.

they occasionally make stupid comments like "we don't make decisions based on numbers"

"If it saves even one life..."
