Now it is interesting to see which paper were fraudulent. Sponsored by industry or not? Specific authors, for specific institutions? Particular kinds of research?
If I was this lazy and unethical, I'd probably not do the experiments/study in the first place and just pocket the funding.
Rare? Scientific misconduct is rampant. It seems like theres a new professor every day being caught out on retraction watch.
It's also far more important for science to keep its hands clean because fair or not its public relations is important. In our high technological society, we cannot allow people to lose faith in the scientific process, It would be a global disaster.
