Skepticism and Controversy
Although not a recognized scientific discipline, people who study certain types of paranormal phenomena such as telepathy refer to the field as parapsychology. Parapsychologists claim that some instances of telepathy are real. Skeptics say that instances of apparent telepathy are explained as the result of fraud, self-delusion and/or self-deception and that telepathy does not exist as a paranormal power.
Parapsychologists and skeptics agree that virtually all of the instances of more popular psychic phenomena, such as mediumism, can be attributed to non-paranormal techniques such as cold reading. Magicians such as Ian Rowland and Derren Brown have demonstrated techniques and results similar to those of popular psychics, without paranormal means. They have identified, described, and developed psychological techniques of cold reading and hot reading.
A technique which shows statistically significant evidence of telepathy on every occasion has yet to be discovered. This lack of reliable reproducibility has led skeptics to argue that there is no credible scientific evidence for the existence of telepathy at all. Skeptics also point to historical cases in which flaws in experimental design and occasional cases of fraud were uncovered.

Famous quotes containing the words skepticism and/or controversy:
“A major problem for Black women, and all people of color, when we are challenged to oppose anti-Semitism, is our profound skepticism that white people can actually be oppressed.”
—Barbara Smith (b. 1946)
“And therefore, as when there is a controversy in an account, the parties must by their own accord, set up for right Reason, the Reason of some Arbitrator, or Judge, to whose sentence, they will both stand, or their controversy must either come to blows, or be undecided, for want of a right Reason constituted by Nature; so is it also in all debates of what kind soever.”
—Thomas Hobbes (1579–1688)
