Willibrord Weijmar Schultz, the Groningen sex researcher (and Ig Nobel winner) who misused the 1985 thesis of an American scholar, and the work of another researcher, in at least five published articles, has tallied another retraction in the affair, his sixth. As we reported earlier, Schultz had been cleared of plagiarism but found to have … Continue reading Another retraction for sex researcher Weijmar Schultz
The fifth of six expected retractions for copyright infringement has arrived for a group of sex researchers led by Willibrord Weijmar Schultz, this one in the International Journal of Gynecological Cancer of a 1992 article.

The Annual Review of Sex Research (which is a supplement to the Journal of Sex Research) has retracted a 1992 paper by a group of researchers who lifted much of their analysis from two even older articles by another scholar. At 21 years post-publication, this is one of the … Continue reading 21-year-old article on the sex lives of women with cancer retracted for data misuse
