"During 2013 and 2014, a total of 1479 people from 77 countries contributed 2985 test sessions. Over the same period, 5738 sessions were run as controls by a computer programmed to simulate human participants. The results showed that with human observers the fringe visibility at the center of the interference pattern deviated from a null effect by 5.72 sigma (p = 1.05 × 10−8), with the direction of the deviation conforming to the observers' intentions. The same analysis applied to the control data resulted in an overall deviation of −0.17 sigma." There are some presentations on Youtube that go into the details of the double-slit line of experiments.
