Can anybody be impartial and unaffected by bias in their opinion on anything?
That's why we like numbers and measurements, as a way to side step this.
But we're all in to a bit of subjectivity now and again.
Well, that's what I think.
I may be biased.
I rang the hospital to tell them that if my wife's condition didn't improve then they could switch off the life support machine.
They said that this wasn't an option for a sprained ankle.
