Don't silence those who challenge consensus

Mary Dejevsky: Don't silence those who challenge consensus - Mary Dejevsky, Commentators - The Independent

US agencies – and perhaps by now our own MI5/MI6 – have units set up with the specific purpose of questioning the prevailing wisdom. Perhaps there should be equivalents elsewhere – in science, in academia, anywhere where an overwhelming consensus threatens to close down discussion? And why not a new broadcasting code that enshrines a similar provision? In the meantime, perhaps Channel 4 would do the natural sceptics among us a favour by repeating The Great Global Warming Swindle, with all the complainants lined up for an immediate right of reply. So we can reach our own conclusion.
