What is the study of events that cannot be explained by known scientific mechanisms called?

The study of events that cannot be explained by known scientific mechanisms is known as parapsychology. This field explores phenomena such as extrasensory perception (ESP), psychokinesis, and various forms of anomalous experiences that fall outside the realm of conventional scientific understanding. Parapsychologists investigate these occurrences aiming to find evidence supporting the existence of abilities that challenge established scientific principles.

Clairvoyance and telepathy are specific concepts within the broader realm of parapsychology. Clairvoyance refers specifically to the supposed ability to gain information about people, events, or objects without the use of the known senses, while telepathy focuses on the transmission of thoughts or feelings from one person to another without using any known human senses. These terms describe specific abilities rather than the overall study itself.

Subliminal perception deals with stimuli that are below the threshold of conscious awareness and how these stimuli can influence thoughts and behavior, which is distinct from the unexplained phenomena studied in parapsychology. Thus, parapsychology encompasses a wider range of topics associated with phenomena that challenge the scientific method and conventional explanations, making it the correct answer in this context.
