The erosion of faith in science comes mainly from two things : the stealing of its benefits from big companies (through secrecy, obfuscation and patents, and the commercial use only of science and technology), and conservative propaganda.

The propaganda itself goes in two ways : the absence of vulgarisation, and the denial of scientific facts and doubting scientist objectivity.

There are problems in sciences and academia, but they are very far from being ore problematic than the political structure around it and the political propaganda.
