@maxdancona,
It's not a conspiracy theory.
Conspiracies involve elaborate secret plans.
In the case of corrupted scientists, there doesn't have to be any kind of elaborate conspiracy. If Evil Corp execs tell the world that a drug is safe, and next week they ask me to study it to see whether it's safe, then I already know what answer they want. They don't have to tell me.
Conspiracies are rare, but so are people who have the courage to tell the emperor he isn't wearing any clothes. Yes men are the norm.
