Precognition: Believers' Brains See Patterns?
On this page
Do paranormal believers think differently about probability?
Imagine you're told that tomorrow it will rain AND a psychic will correctly predict the weather on live TV. Which seems more likely: just the rain, or both events happening together? Most people would say just the rain is more probable—but researchers found something curious when they tested people who believe in paranormal phenomena. These believers consistently made a specific type of logical error, especially when the scenarios seemed to confirm their existing beliefs. The pattern was so consistent that it raises intriguing questions about how our beliefs shape our reasoning.
Paranormal believers make more logical errors when judging unlikely events.
Psychologists have long wondered whether people who believe in paranormal phenomena think differently about probability and logic. A team of UK researchers decided to test this by examining how believers evaluate the likelihood of various events occurring together. They focused on a specific type of reasoning error called the 'conjunction fallacy' - where people incorrectly think two events happening together is more likely than either event alone.
People who believe in paranormal phenomena are more prone to logical errors when evaluating scenarios that seem to confirm their beliefs.
Key Findings
- People who believed in paranormal phenomena made more logical errors overall, regardless of whether the scenarios involved paranormal or normal events.
- Crucially, believers made even more errors when judging scenarios that confirmed their beliefs compared to those that challenged them.
- This pattern was strongest for people who believed in ESP and psychokinesis, with similar but weaker trends for those believing in life after death.
What Is This About?
The researchers recruited 207 people from the UK general public and gave them questionnaires to measure their beliefs in ESP, psychokinesis, and life after death. Then participants read 16 short scenarios describing various situations - some involving paranormal events, others involving everyday occurrences. For each scenario, they had to estimate the probability of individual events happening and the probability of those events occurring together. The researchers specifically looked at whether people made more errors when the scenarios supported their existing beliefs versus when they challenged them.
207 UK participants read 16 hypothetical scenarios and judged the likelihood of paranormal and non-paranormal events occurring alone versus together.
Paranormal believers made more logical errors (conjunction fallacies) overall, especially when the scenarios confirmed their beliefs about ESP and psychokinesis.
How Good Is the Evidence?
207 participants from the UK general public were tested - a medium-sized sample typical for psychological studies examining individual differences in reasoning patterns.
Skeptics argue this shows paranormal believers are prone to wishful thinking and poor reasoning that could explain their beliefs. Believers counter that the study only tests abstract scenarios, not real experiences, and that being hopeful about positive outcomes doesn't invalidate genuine paranormal encounters. Both sides agree that understanding how belief affects reasoning is important for evaluating any extraordinary claims.
Mainstream: This demonstrates cognitive biases that likely contribute to paranormal beliefs and shows why critical thinking education is important. Moderate: The study reveals interesting patterns in how belief affects reasoning, though it doesn't address whether some paranormal experiences might still be genuine. Frontier: While believers may show reasoning biases in abstract scenarios, this doesn't invalidate their real-world experiences or the possibility of genuine paranormal phenomena.
This study doesn't prove paranormal beliefs are wrong - it examines how belief affects logical reasoning about probability, not whether paranormal phenomena actually exist.
To settle questions about reasoning differences, we'd need larger studies across different cultures, pre-registered analysis plans, and replication of the core findings. This study provides initial evidence but represents just one data point in understanding how belief affects logical reasoning.
This study examines paranormal believers' susceptibility to the conjunction fallacy for confirmatory versus non‐confirmatory conjunctive events.

What Does It Mean?
The most fascinating aspect is that our beliefs might literally rewire how we think about probability—paranormal believers weren't just biased, they were making systematic logical errors that followed predictable patterns. It's like discovering that what we believe changes the very architecture of our reasoning.
This is like when someone who believes in lucky numbers thinks it's more likely that both their lucky number will come up AND they'll win the lottery, even though mathematically this combination is actually less probable than just their number coming up alone.
If these patterns hold up in larger studies, they could suggest that belief in the paranormal fundamentally alters how we process probability and evidence. This might mean that simply presenting logical arguments to paranormal believers could be less effective than expected, since the very cognitive mechanisms for evaluating evidence appear to be influenced by existing beliefs. It raises profound questions about the relationship between belief, reasoning, and reality.
This study shows how our existing beliefs can unconsciously influence our logical reasoning, even on seemingly objective probability judgments.

Findings
Paranormal belief was associated with more conjunction errors regardless of event type
moderateMore errors were made for confirmatory over disconfirmatory conjunctions
moderateThese trends existed for extrasensory perception and psychokinesis believers with those for life after death believers approaching significance
