J Hari has fits the model of the cowardly scientist but he ain't even a scientist.
"In 2011, Hari was the subject of two scandals involving his conduct as a journalist. First, he was accused of plagiarism by including in his articles quotes that his interviewees had previously given to other journalists, as if they were the product of his own interviewing. Subsequently, he was found to have anonymously edited the Wikipedia pages of a number of critics of his work so as to present them in a negative light. These behaviours resulted in significant damage to Hari's reputation, and he was asked to return the 2008 Orwell Prize. He was suspended and then resigned as a columnist for The Independent."
"In mid-2011, Hari was also revealed to have made anonymous pejorative edits to the Wikipedia pages of journalists who had criticised his conduct[26][27][28] after Nick Cohen raised concerns in The Spectator.[29] He wrote that he had been attacked on Wikipedia by an editor named "David Rose" (which was later identified as one of Hari's pseudonyms)[30] following a dispute with Johann Hari, and the same editor had made similar changes to the Wikipedia pages of Telegraph columnist Cristina Odone,[31] and Oliver Kamm, a leader writer for The Times[32] after they had been critical of Hari. Cohen also wrote that Hari's own Wikipedia entry had been edited by Rose "to make him seem one of the essential writers of our times".[29] After "David Rose" was later shown to be a pseudonym of Johann Hari, Hari made a public apology for his behaviour.[33]"
