"If you read super carefully, you aren't actually dissagreing."

Yes, I am disagreeing. You say, "only 3 people out of 6 are surely [trying to measure the system impartially]"
I'm saying, no such thing as impartial measurement. All 6 could be genuine. All 6 could be biased. Self-voting doesn't tell you anything certain about impartiality.

Anyway, I suspect much of your concerns will be alleviated when the UI makes it clear that there is no voting, there is only consensus.
