When you just make up data it is easy to do. I work in an FDA regulated industry and work on FDA submissions. If I wanted to I could easily fake data. There is some amount of trust involved that you are acting in good faith, and the punishments for not providing accurate data can be massive. For both moral and legal reasons I would never do that, but it would be easy to do. Eventually though it will catch up to you if you do it in a blatant way.

“Assume good faith” is a necessary assumption to make industry run smoothly, however jackasses can absolutely take advantage of that system to procure short term gains. 

I completely agree with how easy it is to fake data. I worked at a company and it was extremely eye opening how you could easily fake data and get away with it. However, if it eventually came out that you did fake data (which it inevitably would) your ass would be grass along with your whole team. It could be easily done, but the vast majority of people won’t because the punishment and moral concerns are too high
