most real life people don't have multi-billion $$ reasons to lie do they? When one person stands to gain nothing by lying about something they experience, the same can't be said of the funded, & granted research community. There's also university tenure and other privileges as well as fame and being published and read by peers on the line for those who admit to data manipulation and fraud. Just read a news report or two of disgraced scientists who perpetrate this kind of fraud on millions of people. It can really be a trust-killer and it's not fair to the honest and hard working scientists out there but because their communities foster such an environment they can be tarnished by the same brush....
