Question

Quizplus · Accepted Answer

All three statements are true. The first statement is supported by the fact that many parapsychology studies have produced inconsistent results, even with the same researchers and subjects. The second statement reflects the belief among some ESP researchers that parapsychological abilities may be influenced by factors such as belief, motivation, and environmental conditions, making them difficult to study under controlled laboratory conditions. The third statement reflects a common criticism of parapsychology research - that the results may simply be the product of chance, especially for participants who only show above-chance performance on a single test.
