LETTER : Briefly

Lewis Wolpert notes in his column (Review, 28 April) that, in order to decide whether an effect exists or not, it is more reliable to go by the results of randomised trials than by limited personal experience. Since exactly this approach, when applied to the question of whether faculties such as telepathy exist, has produced strong evidence that they do, I look forward to an article by Professor Wolpert where he says that having examined such evidence he has realised that his earlier view that telepathy was nonsense was an error.
