Faith = Bias

'Bias is a term used to describe a tendency or preference towards a particular perspective, ideology or result, especially when the tendency interferes with the ability to be impartial, unprejudiced, or objective

Isn't this exactly what faith is?

If I was a believer, and a skeptic accused me of bias, I would simply respond 'Yes, of course I'm biased.'

Actually, I am quite biased. I really genuinely do think that Judaism is by far the best religion there is. I also think my kids are georgeous. You say I'm biased? I probably am. So sue me.
