Overcoming Bias discusses biases in the system. A quote:
In this recent entry, Eliezer discussed what might be called the "pork-barrel paradox" in politics, that even when there is public support for reducing the size of government, the political constituency for individual programs can be strong enough to keep them all going. He also points out that the occupations represented in Congress don't match the country at large, and maybe don't match what we really need. (To briefly quote myself, I'm willing to believe that the country's 890,000 lawyers are being overrepresented, but what about the 114,000 biologists? A few of these in Congress might advance the understanding of public health. And then there are the 290,000 civil engineers--I'd like to have a few of them around also. I'd also like some of the 280,000 child care workers and 620,000 pre-K and kindegarten teachers to give their insight on deliberations on family policy. And the 1.1 million police officers and 340,000 prison guards will have their own perspectives on justice issues.)
