Video on Science and Politics
When ever science and politics interact science is more often than not the looser. This does not mean that all interactions between science and government are negative but the overall affect on science is negative. The Reason for this is that politics is about acquiring and holding on to power and not knowledge. In fact politics often is destructive to knowledge since ignorant people are easier to control. Further more politicians are often not really interested is the science but sending money to their districts. The biggest example of this is manned space flight which has stagnated for 30 years under government control. Even worst government often favors some lines of research over others in funding, education, and recognition. Some times government favors one side in a scientific dispute over others. The best examples are in origins research and climate research.
