There are all kinds of problems with science. I am a natural skeptic, despite the arguments I make here. Because my views are complex and nuanced and not hard on one side or the other. There are some good books. See Ben Goldacre on "Bad Science" and "Bad Pharma". I used to have a poster diagramming dozens of different biases. I could go on and on about the specifics, far beyond just funding bias, but I'd be preaching to the choir. You can dig into https://retractionwatch.com or consider https://brokenscience.org or any number of other efforts at fixing science.
But if all science is just thrown out, then we know nothing. Everything is just a guess. You get to pick what you wish were true. Personal experience is a poor replacement.
Let me bring that home. You have lost weight and lowered your blood pressure. But have you supressed cancer growth? Have you stopped the progression of atherosclerosis? Are you going to make it to 90? How would you know? The published science doesn't disagree with what you have discovered. Losing weight and lowering blood pressure on an all-meat diet are not in conflict with the nutritional science.
