Recently, quite a few people who occasionally use Wikipedia have told me that they have noticed that this useful online encyclopaedia is left leaning in some of its entries. I always assumed this might just reflect the same bias in the media as a whole. But I was wrong. The bias does not emerge by default but is vigorously enforced, as this story on Wikipedia global-warming propaganda shows.

Lawrence Solomon, executive director of Energy Probe and author of The Deniers, sums up the situation well:

In theory, Wikipedia is a "people's encyclopedia" written and edited by the people who read it; so on controversial topics, one might expect to see a broad range of opinion.  But on global warming, Wikipedia offers consensus, Gore-style -- a consensus forged by censorship, intimidation, and deceit.

Solomon undertook several attempts to edit the Wikipedia page on global warming and to delete mistakes for instance about British scientist Bennie Peiser, only to find his entries eradicated time and again. Obviously in the people's encyclopaedia there are two classes of editors: one with genuine imprimatur and another that may be censored. Solomon discovered that network administrator William Connolley, a ruthless enforcer of the doomsday consensus, uses his authority to ensure Wikipedia readers see only what he wants them to see.  Any reference, anywhere among Wikipedia's 2.5 million English-language pages, that casts doubt on the consequences of climate change will be bent to Connolley's bidding.

There are other examples of course. Just look at the pages Roe v. Wade or Intelligent Design and make up your own mind.
