More Eyeballs, Less Bias

Wikipedia’s political articles are more likely to lean “mildly” Democratic—or to slant left—than Britannica’s. The extent of the bias in Wikipedia entries is greater.

Wikipedia articles with more revision in them had less bias and were less likely to lean Democratic. The largest biases and slants arise on Wikipedia articles with fewer contributions.

This is largely consistent with Linus’s Law, a principle applied to software development that claims that “given enough eyeballs, all bugs are shallow."
