If it's anything like the data fabrication I've seen in industry, it's lack of ethics, laziness, mixed with deadlines/constraints beyond the individuals control, with a dash of arrogance that the conclusion is still correct, regardless, and it'll be fine. I've also seen very qualified people have a massive holes in their perception, making them somehow unaware that they're generating garbage, and even defending the garbage when it's pointed out.
