In 2002, the National Science Foundation’s Science and Technology Indicators report cited a nationwide NSF-sponsored survey which showed 60% of adult Americans agreeing that “some people possess psychic powers or ESP”. As in similar European surveys, this percentage has been increasing in recent years, and is significantly higher among those with higher levels of academic achievement (Radin, 2006, pp 38-40.) In fact, among mainstream scientists, the belief that extra-sensory perception was "an established fact" or "a likely possibility" was shared by 56-67% of respondents, depending on the survey (Carter 2007, pp. 89). Among college and university professors, the overall acceptance rate for ESP was 2/3 (Radin 1997, pp. 226).
