It is not possible to have unbiased communication. Whenever you communicate with someone, you do it because you think it's important that the other person hears what you're about to say. This means that you filter all communication through your own moral system, which obviously has biases. When people say "this is unbiased" they usually mean "this matches the biases of my culture". Wikipedia illustrates this very well because both cultures can claim "obviously the article in my language is unbiased, while the other one is weird".

So in a way, I'd argue that Wikipedia having different biases in different language versions actually proves that it's quite unbiased. If all languages had exactly the same content, the most likely explanation would've been that one culture dominates, and the rest are just translations.

I'd love to see someone make a less biased encyclopedia. It's easy to throw stones. I think people hate that there is an open and valuable source of information on the internet that isn't monetized.

Wikipedia is a treasure
