Wikipedia is simultaneously indispensable and indefensible.
Indispensable because you can get a quick and dirty summary of some topic about which you have neither the time nor the inclination to do a deep dive. It also is a good place to start when you need to find source articles for many of the claims made in the Wikipedia article. The footnotes can be very useful as a place to start.
Indefensible because the articles are often biased, and on controversial topics there are sometimes editing wars where competing narratives are promoted by partisans. Inserts and deletions can happen all the time and you might find different spins on the same topic if you check at different times.
In other words, Wikipedia can be useful, but unreliable as a source of facts. We all use it and feel guilty about it.
A great example of the problem was pointed out by Ian Miles Chong just now.
Most of Earth: “The MSM is biased.”
Wikipedia: “Cite MSM source to confirm this claim.” 🤣🤣
Wikipedia has a non-trivial left-wing bias.@jimmy_wales, what are your thoughts?
