An international group of university researchers is planning a new journal which will allow articles on sensitive debates to be written under pseudonyms. They feel free intellectual discussion on tough issues is being hampered by a culture of fear and self-censorship. The Journal of Controversial Ideas will be launched early next year. He revealed plans for the publication on University Unchallenged, a BBC Radio 4 documentary about viewpoint diversity in academia. University Unchallenged is broadcast on BBC Radio 4 at 20:00 GMT on Monday, 12 November and is available on BBC Sounds afterwards.
