I’m curious about whether those who would use Amazon Mechanical Turk as part of a research project are aware of this dynamic. From Uberworked and Underpaid, by Trebor Scholz, loc 908:
One Turker, Rochelle LaPlante, also reports that some workers seek out academic surveys because they gain a sense of accomplishment from contributing to research. “There is both financial and emotional payment, and some workers seek out one type of payment over another. Some say: ‘It’s okay if this study only pays $ 1/ hour because I feel good about contributing to science,’” she notes.
