Whatsoever the government sponsors, tends to turn bad. Since government funds are ill defended, grantsmanship based government funded memetic diseases will always outcompete truth based science, and similarly grantsmanship funded memetic diseases will always outcompete art based on beauty. Government funded art will rapidly become ugly and stupid. Government funded science will rapidly become untruthful and stupid, string theory as much as global warming theory.
China developed gunpowder, cannon, ocean going ships, the magnetic compass, paper, printing, and so on and so forth long before the west did, and then all these things went into decline. They were not government suppressed, rather they were government sponsored, which had very much the same effect as government suppression. The objective of things like the encyclopedia of all knowledge was to promote and preserve knowledge, though the actual effect was to suppress and forbid knowledge. Only what higher bureaucrats thought they knew got into the encyclopedia, and if you knew more than higher bureaucrat, obviously you were defying authority and promoting ignorance and misinformation – the mechanism was very similar to today’s global warming consensus. Scientists that do not go along with the consensus are apt to lose their jobs and cannot be published through regular channels.
Academia is under strong selection to show cleverness, but weak selection to show contact with reality. However they are only under strong selection to show cleverness so long as the top ranks are filled with clever people so that you have to show cleverness to fit in. Global warming theory, white studies, and so forth require extreme stupidity to fit in, as illustrated by Rahmstorf’s triangular filtering, just as modern art requires the complete lack of good taste or any artistic talent in order to fit in, and as a result the top ranks of academia are increasingly filled with people as dumb as posts, for example Henry Louis Gates – thus soon, to fit into the highest ranks of academia, you will need to be thick as a brick.
The practical consequence of government support, if government support is sufficiently substantial and vigorous, is that only those things that governments are capable of doing get done – and government cannot do much.
