Column chart
Reported flu shots when a shot meant getting paid
What happens to screening answers when one answer is the way in

Results from a randomised survey experiment with 2,275 respondents. When a recent flu shot had no bearing on eligibility, 52.2% reported one. When it made them eligible for a paid task, 63.1%, 62.8% and 62.1% reported one at 5, 10 and 20 dollars, and paying more did not increase lying. Use it as a reminder to write screening questions where the qualifying answer is not obvious, and to check answers against your own records where you can.
