Since it was published last year, The Spirit Level – Kate Pickett and Richard Wilkinson’s book on why equal societies do better than unequal ones – has become a sparkplug for heated, testy debate. Not one, not two, but three pamphlet-length critiques of it have been published, while others have rushed to man the book’s intellectual barricades (‘This book’s inconvenient truths must be faced’, said a Guardian editorial).
Yet now Pickett and Wilkinson have imposed an extraordinary condition on future debate about their book. Because much of the criticism of The Spirit Level has consisted of ‘unsubstantiated claims made for political purposes’ (in their view), ‘all future debate should take place in peer-reviewed journals’, they decree.
Wow. In one fell swoop they have painted any criticism of their book that appears in non-peer-reviewed journals as somehow illegitimate. They snootily say that ‘none of [the] critiques are peer-reviewed’ and announce that from now on they’ll only engage in discussions that ‘take place in peer-reviewed journals’. So any peep of a critique that appears in a newspaper, a book published by a publishing house that doesn’t do peer review, a non-academic magazine, an online magazine, a blog or a radio show – never mind those criticisms aired in sweaty seminar rooms, bars or on park benches – is unworthy because it hasn’t been stamped with that modern-day mark of decency, that indicator of seriousness, that licence which proves you’re a Person Worth Listening To: the two magic words ‘Peer Reviewed.’
