Just scanning the wikipedia article on scientific misconduct, https://en.wikipedia.org/wiki/List_of_scientific_misconduct_... , it looks like Biology and Medicine are the most likely to suffer from fabricated evidence.

Then there is the replication crisis and sokal and its spawn repeatedly showing a lack of rigor and scrutiny in certain fields.

People act shocked when there the public distrusts "science" so much. I don't think its surprising at all. People don't distrust science. They distrust scientists. And there is ample evidence to show they are just as flawed and fallible as anyone else
