You can't be impartial; everyone has their own sets of biases that they can't get around. These are sometimes obvious, sometimes not, but they're always there. It's not necessarily intentionally dishonest to say you're impartial, but it fundamentally is dishonest to claim you're capable of the impossible.

You seem to be conflating "try" with "being" (and possibly also "a little biased" with "a lot biased"). If I currently have a 12 minute mile and I try to get it down to 6 minutes, but only mange to get it down to 8 minutes I have both:

1. Not lied about my goal

2. Accomplished something similar to my goal.
