Why Is There Confusion over the Plural of Bias?
Bias looks a little a like analysis and oasis, both of which derive from Greek. The plurals of analysis and oasis are analyses and oases (pronounced with an "eez" ending), and this leads to some mistakenly giving biases a similar "eez" ending. Bias does not derive from Greek, and it does not end -is.The old plural biasses is now obsolete. [evidence]
