Psi hit and psi miss are terms used in discussion of parapsychological experimentation to describe the success or failure of the subject in achieving the desired result more often than could be expected through chance alone.[1] Used only when the results are notably better than chance.[1]
A psi miss is specifically used to refer to instances where the subject has failed to achieve the result through psi, rather than where they have a non-significant negative score gained through random guessing.[1][2]
