(I keep reading about it but I never used it) Does mTurk have some sort of quality-related metrics respectively higher rewards linked to it? For example when I submit some work can I specify "I want only at least 4-stars-people (out of 5, where "5" is for people that rarely make mistakes) to work on this and yes I will pay 4$ extra fees for 4-stars and 8$ extra fees for 5-stars rated workers"? Thx
