Abstract

A total of 433 case reports of experiences which had reference to a non -inferable, undesirable future event were analyzed to see whether any efforts were successfully made to prevent the occurrence of the foreseen tragic consequences. The author recognizes that instances of successful intervention would rarely be recognizable. However, she applies a set of rigorous criteria to the available cases and ends with a small number which suggest that intervention may be possible even in cases which are truly precognitive in character. These few cases are not offered as conclusive, but for their suggestive value for experimentation in relation to the problem.
