Because that's not what the GP was talking about. For example, say there is some controversial economic policy passed by one of the parties. Then a researcher goes out to research if the policy is working or not. But when they do the research, they find out that the policy doesn't work and has bad side effects too. However, the majority of the university votes and supports the party that passed the policy.

So the researcher intentionally changes some of the ways the data is collected and poof, it looks like the policy works. Extra funding comes your way but now you have committed academic fraud. Not that anything will happen to you for this, but still, you know you did it. That's what the GP is talking about and it happens quite a bit in the humanities and economics. Its why private economists and public economists almost seem like different species.

They are interested in doing some of these things precisely because they are being paid to.
