Christopher Hitchcock and Joshua Knobe are running a study on “intuitions about causation”:http://www.unc.edu/%7Eknobe/causation/index.htm that they’d like you to take. ‘You’ here including any readers of this blog, and friends you have, any random stranger you meet on the street, etc. Unlike the little test I did here, this one features some careful controls, and has even been approved by an Institutional Review Board. So “go at it”:http://www.unc.edu/%7Eknobe/causation/index.htm!
