Read the excert from HUTCHINSON & WATERS (1987) about the ESP origin:

“As with most developments in human activity, ESP was not a planned and coherent movement, but rather a phenomenon that grew out of a number of converging trends. These trends have operated in a variety of ways around the world, but we can identify three main reasons common to the emerge of all ESP.”

Taking into consideration HUTCHINSON & WATERS assumptions, what are the three main reasons for ESP emergence?
