The frequency with which scientists fabricate and falsify data, or commit other forms of scientific misconduct is a matter of controversy. Many surveys have asked scientists directly whether they have committed or know of a colleague who committed research misconduct, but their results appeared difficult to compare and synthesize. This is the first meta-analysis of these surveys. To standardize outcomes, the number of respondents who recalled at least one incident of misconduct was calculated for each question, and the analysis was limited to behaviours that distort scientific knowledge: fabrication, falsification, “cooking” of data, etc… Survey questions on plagiarism and other forms of professional misconduct were excluded. The final sample consisted of 21 surveys that were included in the systematic review, and 18 in the meta-analysis. A pooled weighted average of 1.97% (N = 7, 95%CI: 0.86–4.45) of scientists admitted to have fabricated, falsified or modified data or results at least once –a serious form of misconduct by any standard– and up to 33.7% admitted other questionable research practices. In surveys asking about the behaviour of colleagues, admission rates were 14.12% (N = 12, 95% CI: 9.91–19.72) for falsification, and up to 72% for other questionable research practices. Meta-regression showed that self reports surveys, surveys using the words “falsification” or “fabrication”, and mailed surveys yielded lower percentages of misconduct. When these factors were controlled for, misconduct was reported more frequently by medical/pharmacological researchers than others. Considering that these surveys ask sensitive questions and have other limitations, it appears likely that this is a conservative estimate of the true prevalence of scientific misconduct.
Red wine researcher accused of fraud: A University of Connecticut researcher known for his work on red wine’s benefits to cardiovascular health falsified his data in more than 100 instances, university officials said Wednesday. University officials said nearly a dozen scientific journals are being warned of the potential problems after publishing his studies in recent years. The researcher, Dipak Das, did some studies of resveratrol, an ingredient in red wine that has shown potential for promoting health.

Now ask yourself; if the person lecturing me on the latest and the greatest dental product, high tech device, et al has a fiduciary link to the dental manufacturer or distributor, regardless of whether it’s paid advocacy or royalties, can you take the presentation on faith?
