What they're saying is that the level of corruption and false claims varies dramatically by field. Biology/medical/public health/social science seems to be incredibly corrupt but e.g. computer science doesn't have the same issues in the same way. Even then you can drill down to sub-fields, so ML has bigger problems within CS than computer graphics does for example.

I didn't say you were a bad person. Your personal experiences in a field as large as "scientific research" offer you no useful information to judge that entire field.
