"The inherent uncertainty of research provides a safe haven for data omission, manipulation or exaggeration. Because interpretation of data is an imperfect science, there are few consequences for those tempted to oversell their findings.
On the contrary, ...faulty embellishment can help to determine whether a study is published--and where.... significant errors or falsehoods may be overlooked or simply pass unchallenged. As a result, modern science can churn out a flotsam of dead-end data that pollute the literature and waste precious resources." Jim Woodgett, Nature, 05 Sept. 2012
