I’ve heard the “80/10 rule” before about MTurk, and it seems to have come up again in a new article on ‘Citizen Science’ by Sauermann and Franzoni (and the link may not work…I’m at school and have access via the School’s internet to some resources that are behind firewalls when I’m not at school. So apologies).
I’ll dive into this later today and share more information. But it seems like the authors found that 10% of given populations of crowdsourcing workers do 80% of the work.
The article is from the Proceedings of the National Academy of Science and is titled “Crowd science user contribution patterns and their implications.”
