It's a myth that scientists are immune from social, cultural, political or economic influences.  The good ones strive not to let mundane considerations (i.e. bribery) influence their work.  But whenever corporate/capitalist profit is involved, you can bet there will be someone with lots of cash leaning on 'em to report the results they want, and who will use threats when bribery doesn't work.

Such as U.C. Berkeley biologist Tyrone Hayes who reported that agricultural chemicals Monsanto uses on our food altered sexual behavior in male African clawed frogs to where they would only attempt to mate with other males.  Last I heard the guy was still hanging onto his tenure despite repeated attempts to discredit him, but just barely--and company thugs have physically threatened him and his family.  When a US FDA scientist is tasked with review of new drug applications, he does it with 25 pharmaceutical company lawyers standing over his shoulder.
