Opinion: Ethics Training in Science: The NIH has required researchers to receive instruction about responsible conduct for more than 20 years, but misconduct is still on the rise. James Hicks. May 14, 2013. The Scientist.

.... Today, 1 in 3 scientists responding anonymously to surveys admits to “questionable” research practices; research misconduct cases handled by the US Office of Research Integrity (ORI) are at an all-time high; and retractions of scientific papers have increased exponentially since 2005. It should be noted that not all retracted papers involve foul play, but a recent study reported in PNAS surveying 2,047 biomedical and life-science papers revealed that 67 percent of retractions were directly attributable to misconduct.

It strains credibility to imagine that an industry based on harming animals and filled with those who admit to unethical behavior treat their research subjects with compassion or respect.
