Published Research on the Paranormal
Peer-Reviewed Academic Research
I.S.R.A.E. is proud to collaborate with an international team of scientists to tackle the big questions about hauntings, poltergeists, and general “high strangeness”. Below you will find a list of scholarly research articles in which I.S.R.A.E. either directly provided research data or collaborated with other scientists to advance the goal of honest and accurate science in paranormal studies and investigations. When possible, we provide direct links to our collaborative works.
Research below is provided by topic. Research with a DOI link can be directly accessed from here. If you wish to read a paper for which a link does not exist, feel free to write us, and we will try to send you a PDF copy.
