PEAR closed its doors at the end of February 2007. Its founder, Robert G. Jahn, said of it that, "For 28 years, we’ve done what we wanted to do, and there’s no reason to stay and generate more of the same data." Statistical flaws in his work have been proposed by others in the parapsychological community and within the general scientific community. The physicist Robert L. Park said of PEAR, "It’s been an embarrassment to science, and I think an embarrassment for Princeton".
