Can I tell you one thing about science in general. It does actually not matter too much who finance studies or who executes them. It is important that they are peer reviewed. And can be executed the same way at any given time and place. And the results should come to the same or similar conclusion. This is how scince work. It is independent from religion belief or god.
Of course there are studies of poor quality. But those can be pointed out. Not for the autor. But by explaining the methological issues that exist with the given study.
