Investigations by Tilburg and Groningen Universities, in the Netherlands, have found that Diederik Stapel faked research data that was used in at least 30 research papers, Dutch News [1] reported. Stapel, a professor of social and behavioral sciences at Tilburg, was suspended in September as inquiries began into some of his work. In a statement Stapel posted on a newspaper site, he said that he has "failed as a researcher and academic," adding that "I realize now that my behavior has stunned and angered my colleagues and put my area of expertise – social psychology – in a bad light."
