I'm a PhD student at CU-Boulder and am interested in using some data from the Stack Exchange Network to analyze how user Big 5 Personality traits influence network characteristics. The best way for me to do this would be to connect users on the Stack Exchange network to the data at mypersonality.org which already has the Big 5 personality traits of about 4 million users. That's a far larger data set than I could collect on my own at this stage in my academic career even if there is only a 0.01% overlap in users.
I've spoken with the people at MyPersonality and they are willing to work with admins or an API of Stack Exchange to help resolve the users IDs in their research to the userIDs on Stack Exchange through linking Facebook IDs. Is there a functionality to do this (mapping facebook IDs to user IDs) that already exists or do I need to contact Stack Exchange directly?
