The system is managed perfectly to minimise agendas being undermined. Those in power have worked their entire lives to gain it and will have no issue papering over any accusation that veracity is not their sole priority, let alone a complete farce. "In many scientific fields, results are often difficult to reproduce accurately, being obscured by noise, artefacts, and other extraneous data. That means that even if a scientist does falsify data, they can expect to get away with it – or at least claim innocence if their results conflict with others in the same field. There are no "scientific police" who are trained to fight scientific crimes; all investigations are made by experts in science but amateurs in dealing with criminals. It is relatively easy to cheat although difficult to know exactly how many scientists fabricate data" https://en.wikipedia.org/wiki/Scientific_misconduct
