Reality doesn't have a left-wing bias, it has a liberal bias.

(FWIW my experience is that while Grok is more likely to express the right wing perspective on a topic, it's almost invariably as a counterpoint alongside the left wing perspective. I never got it to give an exclusively right wing take. But I do have to regularly prompt ChatGPT et al to elucidate on the right wing view. IMHO I don't want AI to have a left OR right wing bias. Wherever there is a genuine political — not factual — dispute, teaching the controversy is the appropriate response.)
