ESP, or Extrasensory Perception, refers to the ability to gain information without using the known human senses. It is often categorized into several types, including telepathy (mind-to-mind communication), clairvoyance (perceiving distant events), and precognition (predicting future events). While many people believe in ESP, scientific evidence supporting its existence remains limited. Research on ESP has been conducted for decades, with various experiments attempting to validate its claims. Critics argue that results can often be attributed to chance or psychological factors. Despite the skepticism, ESP continues to be a popular topic in parapsychology and among those interested in the unexplained aspects of human perception.
