Strings versus ESP
David Fisher
Abstract
Your report about the recent conference at Cambridge on "rational perspectives on the paranormal" (May p5) discusses attempts by parapsychologists to reproduce paranormal phenomena under controlled laboratory conditions. You then say that "positive results are not unusual, but are rarely repeatable". Surely any repeatable experiments in this field would be regarded as a "holy grail" and pursued relentlessly? The results would no longer be rare by this time, and anybody at all – including sceptics – could reproduce them at will.
