A02 coincidence and probability Flashcards
(37 cards)
What are the 4 sections for the evaluation of the role of coincidence
The illusion if causality may have an adaptive significance
Illusion of connection
Illusion of control
General cognitive ability
Talk about illusion if causality may have adaptive significance
Causal thinking can be adaptive for instance eating a mushroom could be harmful
But this can lead to type 1 errors (a false negative rejecting the null hypothesis when it’s true) (mushrooms are deadly)
Such type 1 errors are tolerated to avoid type 2 errors (mushrooms aren’t deadly)
Who tested illusion of connection
Brugger et al
What did brugger et al do and find
Argues that it’s an adaptive advantage aswell as illusion of causality to see things that aren’t there (seeing lion behind bushes that isn’t actually there is better than missing one)
This ability may cause creativity and creativity is found to be linked with paranormal beliefs thalbourne found
Who tested illusion of control
Whitson and galinsky
What did Whitson and galinsky do and find
Illusion of control was experimentally manipulated.
When Control levels decreased, Pps detected patterns where there were non and formed false correlations between unrelated events.
Conclusion for illusions of control
Supports explanations that illusion if control may increase chances if believing in psi phenomenon
Who tested general cognitive ability for role of coincidence
Jones et al
Evans
Wiseman and watt
What did Jones te al do and find
Findings went against the explanation that believers had worse cognitive abilities
What did evans find and do
Amongst scientists, belief can be high (67%) on esp
What did Wiseman and watt do and say
Believes and non believers only differ in syllogistic reasoning not general cognitive ability
What are the 4 sections for the role of probability judgments
Contrasting research evidence
Correlation is not cause
Cognitive ability
Not misjudgment, simply a different heuristic
Who tested contrasting research evidence?
Blackmore
What did Blackmore do and find
Didn’t find difference between believers and non believers in terms of their probability judgments
Conclusion for contrasting research evidence
Difference could be due to other studies using a general scale to judge whether Pps believed in esp. But Blackmore simply used one question
Talk a about Correlation isn’t cause
Link between probability and paranormal beliefs but this doesn’t prove causation that misjudgment of probability causes paranormal beliefs
Who tested cognitive ability may explain the link between probability misjudgment and paranormal beliefs
Musch and ehrenberg
What did musch and ehrenberg do and find
Found cognitive ability reduced the performance difference between believers and non believers on probability judgement tasks to zero
Conclusion for cognitive ability in terms cognitive ability for role of probability judgements
Poor probability judgements are due to low cognitive ability rather than directly causing a tendency to believe in psi phenomena
Who tested not misjudgment, simply a different heuristic in terms of role of probability
Kahneman and Tversky
What did kahneman and tversky do and find
Probability misjudgment can alternatively be explained in terms of failing to understand heuristics, such as representativeness
What are the 2 sections superstitious behaviour and magical thinking
Explanations for superstitious behaviour
Explanations for magical thinking
What are the 4 sections for explanations for superstitious behaviour
Type 1 and 2 errors
Behaviourist explanation
Illusion of control
What are superstitions
Beliefs tgat aren’t based on reason or knowledge such as believing that number 7 is lucky
