bi-assed two-faced

why do they say "biassed" and not "two-assed" like ib two-faced?

Its biased not biassed and it has nothing to do with asses.

Biassed is how you would describe someone with two rectums.

The 'biassed' and 'biased' spellings are fine for describing someone's prejudicial view.

I've never seen 'bi-assed' used to describe what it implies.

It's spelled ''biased'' and it's pronounced /baI@st/, not /baIæst/.
