Psychological Experiments in Social Media Settings
Winter Mason
Yahoo! Research
This talk describes two research projects designed and executed on two different social media platforms: Facebook and Amazon's Mechanical Turk. In the first project, we designed a Facebook application that allowed us to measure how similar friends' attitudes are, how similar they are perceived to be, and how accurately friends know each other's attitudes. We discover that while friends are highly accurate in guessing what they believe, their actual knowledge of each other's beliefs is much more questionable. In the second project, we studied the effects of financial incentives on two tasks performed on a popular crowd-sourcing platform. We find a significant effect of incentives on quantity of output but no such effect on quality, and pose a surprising explanation for the results.
