Psi Missing

Psi missing is a term used when experimental results appear to show outcomes opposite to the expected direction of a claimed psychic effect.

Overview

In parapsychology, psi missing refers to below-chance performance in a task where above-chance performance was expected if psi were operating. Some researchers have interpreted this as a possible form of negative or avoidant psi response, while critics argue it is better explained by randomness, poor design, or post hoc interpretation. The concept remains debated.

Key Insight

Psi missing refers to unexpectedly below-chance outcomes that some researchers interpret as meaningful rather than purely random.

Scientific Status

Psi missing is discussed mainly in parapsychology and is not accepted as an established scientific phenomenon.

How Researchers Study It

It is analysed through statistical comparison with chance, experimental repetition, and theoretical interpretation of anomalous scoring patterns.

FAQ

  • Does below-chance scoring prove psi missing?

    No. It may simply reflect randomness or methodological issues.

  • Why do some researchers discuss psi missing?

    Because repeated below-chance results can raise questions about response patterns and interpretation.
