To generate entangled photons, a commercial optical system was used (quED, qutools.com, Munich, Germany). This apparatus sends a blue laser beam through a nonlinear crystal to produce pairs of red photons with entangled polarizations. The strength of entanglement was determined by measuring correlations between the polarizations of pairs of photons. To do this, each photon [...]

We recruited seven participants known to the authors and to Dr. Helané Wahbeh (Institute of Noetic Sciences), using purposive sampling. Qualification for inclusion was that participants should be established practitioners of apparent psi abilities and practicing fasting and/or vegetarianism in support of their work. Data collection involved a semi-structured interview using videoconferencing with each participant [...]

From initial ethnographic observations in different mediumistic religions, we obtained the contact information of potential respondents to whom we submitted an online survey developed for this study. The invitation to participate was sent either directly to the members of these groups or through their religious leaders, who helped to disseminate the survey. The survey assessed [...]
