Individuals more easily surprised by coincidences show higher paranormal belief. This suggests surprise thresholds influence belief in the unexplained, impacting how people interpret unusual events.
Area of Science:
- Cognitive Psychology
- Psychology of Belief
Background:
- Coincidences often lack natural explanations, leading some to favor paranormal interpretations.
- Understanding the psychological factors influencing paranormal belief is crucial.
Purpose of the Study:
- To investigate the relationship between surprise thresholds for coincidences and paranormal belief.
- To determine if individuals with a lower surprise threshold exhibit greater paranormal belief.
Main Methods:
- Participants rated the remarkability of artificial, formally defined probable and improbable coincidences.
- Paranormal belief was assessed using the Australian Sheep-Goat Scale.
- Statistical analysis examined the interaction between surprise thresholds and coincidence type.
Main Results:
- A significant interaction was found between Sheep-Goat scores and coincidence type.
- Individuals with lower surprise thresholds reported higher paranormal belief when experiencing coincidences.
Conclusions:
- Lower surprise thresholds are associated with a greater propensity for paranormal belief.
- The study provides insight into cognitive biases that may foster belief in the paranormal.
