Here's our latest study on mediumship: "Prediction of Mortality Based on Facial Characteristics". Available here: https://t.co/jVMHmF07Dj— Dean Radin (@DeanRadin) May 21, 2016
In the study,
“Participants were asked to press a button if they thought the person in a photo was living or deceased. Overall mean accuracy on this task was 53.8%, where 50% was expected by chance (p < 0.004, two-tail). Statistically significant accuracy was independently obtained in 5 of the 12 participants.”
The abstract claims the participants showed better than chance performance, but even if we accept this level of accuracy at face value (so to speak), the mediums were wrong 46.2% of the time. Remember that before your next psychic reading.
And of course we should not accept the results at face value. Let's take a closer look at the paper (Delorme et al., 2016), which was published in Frontiers in Human Neuroscience.

Actually, let's take a closer look at the authors first. Arnaud Delorme, Alan Pierce, Leena Michel, and Dean Radin are all affiliated with the Institute of Noetic Sciences (IONS), a parapsychology research institute in California. Dr. Delorme is also affiliated with UC San Diego. Along with Scott Makeig, he developed EEGLAB, a Matlab toolbox that's widely used to analyze EEG data. Delorme and Makeig (2004) has been cited 5738 times (as of this writing).
Why is Delorme doing parapsychology research?? He's a long-time Zen meditator, according to his IONS biography. Why is Frontiers publishing parapsychology research? Here's one opinion.
Dead or Alive?
Figure 1 (Delorme et al., 2016). Process involved in creating a group of photographs of “Alive” and “Deceased” individuals.
Photographs of known alive and dead people were selected from three internet databases: (D1) school portraits from 1939–1941; (D2) school portraits from 1962–1968; and (D3) politicians (US senators excluded) and businessmen. Why? Why use pictures of US Representatives and state politicians outside of California? Even though the subjects said they didn't recognize them, there could be a vague sense of familiarity with some of these faces.
Photos of 404 individuals were presented, and the 12 participants pressed keys to indicate “deceased,” “living,” or “do not know”. 1
The participants all “claimed to be able to experience feelings of vitality from facial photographs alone. ... They were required to have been performing professional ‘readings’ for clients...” THERE WAS NO CONTROL GROUP. In other words, participants who did not claim any psychic or clairvoyant abilities were not included in this study. Thus, there was no way to know if the marginal ability to discern whether a person was alive or dead was based on mediumship.
And marginal it was. Basically, they were terrible at determining whether people in old yearbook photos were dead or alive. Terrible. No better than guessing. 2
Given the number of statistical tests, we should only consider values with *** (p<.001), of which there were two (out of 35 possible comparisons). Therefore, the evidence for mortality prediction (clairvoyance) should not be taken seriously, despite the authors' conclusion:
We do not rule out the hypothesis that subjects might have had access to information in ways that are not currently understood by modern physics and could potentially go beyond classical information delivered by facial features.
Paranormal physics do not apply to old photographs, however.
And the EEG data were equally unconvincing. The face-specific N170 component did not differ based on dead or alive, correct or incorrect. The earlier P1 component showed a small difference between correct and incorrect responses for the deceased only, but there was no good explanation for this (“Future research could assess if low-level visual image characteristics and attentional modulation were important factors in leading to this difference in electrocortical activity”).
The truth is out there, but this study provides no proof that the #Supernatural actually exists.
1 The “do not know” responses were not included in the analyses, and we have no idea of how many such responses were recorded.
2 Oh here's a fun fact. S06 indicated that 90% of the people in the photos were dead.
