That said, I find Wikipedia's biases predictable, avoidable (topic specific) & also very interesting as a sociological study in itself.
Firstly, it reminds us of inherent bias in (mostly colonial-written) paper encyclopedia of the past. There has never been an unbiased encyclopedia written & seeing the biases fully sourced & rapidly evolving in realtime serves as an excellent crystallisation of slower processes in previous works: highlighting that many of the historical "facts" we all grew up with were ultimately fed to us by similarly biased groups.
I've also come to the slow realisation that this may be a fundamentally unsolvable problem & that simply categorising it as "biased beyond repair" & continuing to handle it in that manner may be the best thing we can do.
