The delusion, that is, that Science can be somehow shielded from Politics.
Science is big and needs public money. Public money distribution is dictated by policy. Policies depend on politics. Therefore science depends on politics.
Therefore science is bound to be politicized. In the US it will forever slide between all-Dems and all-GOP according to contemporary mores.
In the UK, Science will remain forever prisoner of the Establishment. In Italy, it will be allowed to do whatever doesn’t hurt whoever is in charge of the “control room”.
The only way out is to make Science become the Fourth Branch of Government.
