"We also asked the Mechanical Turk workers to declare their educational level. In general, the (selfdeclared) educational level of the workers is higher than the general US and Indian population. There are two factors that may contribute to this. First, many of the workers are younger than the overall population and, ceteris paribus, this leads to higher educational level. Finally, while we may not necessarily discount the possibility of false disclosure, there are no incentives that would bias workers towards lying in this survey."
