I'm not sure this is necessarily always true. There are absolutely certainly instances of this happening, but more and more governments are adopting "evidence-led policy" policies, and I'd hope that at least sometimes those policies do what they say on the tin. The UK has this: https://www.gov.uk/what-works-network and I'm going to try and do more reading up on it to see whether it looks like it's doing any good or just proving what people want it to prove.
It would certainly be preferable to live in a world where social scientists did good unbiased social science and then politicians listened to them. The question is, how do we change our current world into such a world? It certainly isn't by disparaging social science or assigning it low prestige. We need to make it so that science>ideology in prestige terms, which will be really tricky.
I'm not sure this is necessarily always true.
Yes; you'll get some politicians who actually want to reduce the crime rate and are willing to look for advice on how to do that effectively.
They're hard to spot, because all politicians want to look like that sort of politician, leaving the genuine ones hidden in a crowd of lookalikes...
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves. (Step-by-step, foolproof instructions here; takes <180seconds.)
If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
