goes against the existence of precognition, this data will always be claimed to be inaccurate by precognitions proponents making any attempts to disprove it pointless. Due to precognitions elusive nature, there would need to be a way to test precognition which accounted for its random nature. The solution to this was to use Sequential Forced-Choice Precognition Tasks with five stimuli. Once the data is collected statistics must be used in order to separate the precognitive patterns from the random ones. This is known as accounting for Bayesian Inference. This is an alternative means of gathering data. Normally data is collected using frequentist statistics. This calculates how likely something is to happen through a long running experiment. This is why when experiments are done the same conditions are maintained to maintain a certain outcome. With Bayesian Statistics probabilities are applied in order to account for differences found in new data. However, for scientific experiments control and consistency are necessary to collect data is accurate. This ensures that if a certain experiment is repeated by someone else the data can be compared evenly leaving no room for error. Even with these changes made to how testing for precognition was done, this was still not enough to find supporting evidence of precognition.
Parapsychologists will do everything in their power to ensure that null results in various experiments are not proof that the phenomenon does not exist. Richard Wiseman explores this issue in his epilogue in the book “Debating Psychic Experience: Human Potential or Human Illusion?”. He feels that time is running out for parapsychological research as after over a hundred years of research there is still no unequivocal proof of psi. For some reason parapsychology research has not been stopped by the endless null findings. Most hypotheses with null results are thrown to the side relatively quickly, however when null results were concluded from research into parapsychological abilities, there was always some excuse for why no meaningful results came from the experiment. This book contains several chapters written by Dean Radin who has performed tests that had supposedly proven ESP to be real as talked about earlie
