Do You Believe? New Scale Rates the Paranormal
On this page
How do scientists measure what people believe about the paranormal?
Imagine you're at a dinner party where someone mentions they believe in ghosts, another swears by horoscopes, and a third insists they've had prophetic dreams. How do you measure something as personal and varied as paranormal beliefs? Psychologist Jerome Tobacyk faced exactly this challenge when he set out to create a scientific tool that could reliably assess what people believe about the unexplained. His revised scale doesn't judge whether these beliefs are true or false — it simply maps the landscape of human conviction about phenomena that science hasn't fully explained.
Researchers created an improved questionnaire to measure people's paranormal beliefs across seven categories.
Psychologist Jerome Tobacyk wanted to better understand how people think about paranormal phenomena. Rather than studying whether psychic powers actually exist, he focused on measuring what people believe about them. His goal was to create a more accurate scientific tool for assessing these beliefs.
Scientists developed a reliable psychological tool to measure paranormal beliefs across seven distinct categories, treating belief itself as a measurable phenomenon worth studying.
Key Findings
- The revised questionnaire performed significantly better than the original version.
- It was more reliable (gave consistent results), more valid (actually measured what it claimed to measure), and worked better across different cultures.
- The seven-point rating scale allowed for more nuanced responses than the previous version.
What Is This About?
Tobacyk revised his earlier paranormal belief questionnaire, expanding it from 25 to 26 questions and changing the rating system from a simpler scale to a seven-point scale. He organized the questions into seven categories covering different types of paranormal beliefs: traditional religious beliefs, psychic abilities (psi), witchcraft, superstitions, communication with spirits, extraordinary life forms like Bigfoot, and precognition (seeing the future). He then tested this revised questionnaire to see if it worked better than the original version.
Development and validation of a revised questionnaire scale to measure people's beliefs in paranormal phenomena across seven categories.
The revised scale showed improved reliability, validity, and cross-cultural applicability compared to the original version.
How Good Is the Evidence?
With 484 citations, this study has been referenced nearly 500 times by other researchers - roughly equivalent to being cited once every two weeks since publication, indicating its significant impact on the field.
This is a methodological study focused on questionnaire development rather than experimental testing. Not pre-registered (uncommon for this type of research in 2004). No blinding needed as it's a survey validation study. Sample size not specified in abstract. No experimental effects reported, but psychometric properties (reliability/validity) were assessed. Data availability not mentioned. The scale has been widely replicated and used by other researchers (484 citations). Published in a specialized transpersonal psychology journal.
The study focuses on scale development rather than investigating actual paranormal phenomena, limiting direct insights into the validity of paranormal beliefs themselves. The paper lacks detailed psychometric data, sample demographics, and validation procedures that would allow full assessment of the scale's quality. Without access to reliability coefficients, factor analyses, or convergent validity data, the claimed improvements cannot be independently verified.
Mainstream: This is useful psychological research that helps us understand human cognition and belief formation, regardless of paranormal validity. Moderate: Measuring beliefs systematically is a necessary first step before we can properly study whether any paranormal phenomena have merit. Frontier: Better measurement tools will help identify people with genuine paranormal experiences and separate them from mere believers.
Common misconception: This study proves or disproves paranormal phenomena. Reality: This research only measures what people believe about paranormal topics - it doesn't test whether those phenomena actually exist. It's like polling people about their political views rather than studying politics itself.
To fully validate this scale, we'd need large-scale testing across diverse populations, demonstration that it predicts relevant behaviors, and evidence that the seven categories are truly distinct. This study provides the foundational psychometric validation but would benefit from broader demographic testing and behavioral correlation studies.
A 26-item Revised Paranormal Belief Scale is introduced which provides a measure of degree of belief in each of seven dimensions with improvements that provide greater reliability and validity.

What Does It Mean?
This study essentially created a 'belief thermometer' for the unexplained — turning the deeply personal question of what we believe about reality into something scientists can measure, compare, and study across cultures and time.
This is like creating a better personality test, but instead of measuring traits like extroversion, it measures how much someone believes in things like ghosts, psychic powers, or lucky charms. Just as dating apps use personality questionnaires to match people, researchers use belief scales to understand how paranormal beliefs relate to other aspects of psychology.
Good questionnaires need validation - just because questions seem reasonable doesn't mean they accurately measure what you think they do. Researchers must test whether their scales are reliable (consistent) and valid (accurate) before drawing conclusions.
