Scientists faking their government-funded research and defrauding taxpayers are drastically increasing in number, and a major federal agency has no idea how much of its $7 billion investment is lost to such misconduct, waste or theft, The Daily Caller News Foundation Investigative Group has learned.The National Science Foundation (NSF) funds research projects to the tune of $7 billion in taxpayer funds every year, but officials there dont estimate how much goes to cheaters who manipulate data, plagiarize and steal public money.We dont generally speculate about how much misconduct is undetected, NSF spokesman Bobbie Mixon told TheDCNF.
