The Noetic Signature Inventory: Development, Exploration, and Initial Validation

Noetic experiences—inner wisdom or direct knowing beyond ordinary senses—are common worldwide, yet no tool existed to measure them. Through three studies with 521 participants, researchers developed and refined the Noetic Signature Inventory (NSI), a 44-item questionnaire capturing 12 distinct facets of noetic experience: Inner Knowing, Embodied Sensations, Visualizing to Access or Affect, Inner Knowing Through Touch, Healing, Knowing the Future, Physical Sensations from Other People, Knowing Yourself, Knowing Others' Minds, Apparent Communication with Non-physical Beings, Knowing Through Dreams, and Inner Voice. The NSI showed good internal consistency, convergent and divergent validity, and test-retest reliability, providing a standardized way to study individual differences in noetic experiences.

Abstract

Noetic comes from the Greek word noēsis, meaning inner wisdom or direct knowing. Noetic experiences often transcend the perception of our five senses and are ubiquitous worldwide, although no instrument exists to evaluate noetic characteristics both within and between individuals. We developed the Noetic Signature Inventory (NSI) through an iterative qualitative and statistical process as a tool to subjectively assess noetic characteristics. Study 1 developed and evaluated a 175-item NSI using 521 self-selected research participants, resulting in a 46-item NSI with an 11-factor model solution. Study 2 examined the 11-factor solution, construct validity, and test-retest reliability, resulting in a 44-item NSI with a 12-factor model solution. Study 3 confirmed the final 44-item NSI in a diverse population. The 12-factors were: (1) Inner Knowing, (2) Embodied Sensations, (3) Visualizing to Access or Affect, (4) Inner Knowing Through Touch, (5) Healing, (6) Knowing the Future, (7) Physical Sensations from Other People, (8) Knowing Yourself, (9) Knowing Other's Minds, (10) Apparent Communication with Non-physical Beings, (11) Knowing Through Dreams, and (12) Inner Voice. The NSI demonstrated internal consistency, convergent and divergent content validity, and test-retest reliability. The NSI can be used for the future studies to evaluate intra- and inter-individual variation of noetic experiences.
