A Skeptical Eye on Psi

Research on extrasensory perception (ESP) or psi is contentious and highly polarized. On the one hand, its proponents believe that evidence for psi is overwhelming, and they support their case with a seemingly impressive series of experiments and meta-analyses. On the other hand, psi skeptics believe that the phenomenon does not exist, and the claimed statistical support is entirely spurious. We are firmly in the camp of the skeptics. However, the main goal of this chapter is not to single out and critique individual experiments on psi. Instead, we wish to highlight the many positive consequences that psi research has had on traditional empirical research—an influence that we hope and expect will continue in the future
