Amazon’s mTurk platform, which claims to have over 500,000 workers, produced a very low eligible yield (n=9) but the highest-quality surveys (100%). We attribute the high-quality yield to using only “mTurk Masters” who had a 95% approval rating. However, use of this selective qualification could similarly have limited the number of eligible participants, attributing to our low eligible yields. Loss-to-follow up from our screener to the main survey contributed to the low yield; going forward, we will likely combine the screener into the main survey, pay a smaller fee for the screener portion, and a quality bonus for eligible completers.
