In a Mirror, Darkly Does superstition reflect rationality? Konrad Talmont-Kaminski
The very model of irrationality • A superstitious person • Begins the day with a ritual • Avoids crossing the path of a weasel • Looks for meaning in dreams • Will not stand on a grave • Treats some days of the month as special • Spits to protect himself against evil spirits TheophrastusCharacters (370 - circa 285 B.C.)
What’s changed in 2300 years? • Richard Wiseman, Hertfordshire (2003) • Knocking on wood 74% • Crossing fingers 65% • Not walking under ladders 50% • Gallup, US (2001) • ESP 41% • Haunted houses 37% • Telepathy 31% • Any one of 10 listed beliefs 73%
More data • CBOS, Poland (2006) • Signs of the zodiac 30% • Lucky objects 26% • Unlucky days 24%
Ubiquitous superstition • Superstitious beliefs are highly resistant to • scientific advances • philosophical argumentation • cultural progress • Superstitiousness has not been eliminated by evolution • Superstitiousness is still (nearly) universal, both as • tendency to accept superstitious beliefs • actual holding of superstitious beliefs
The irrational animal • Aristotle • Man is a rational animal • Bertrand RussellUnpopular Essays • It has been said that man is a rational animal. All my life I have been searching for evidence which could support this.
Two problematic questions • Why is superstition so hard to get rid of? • Are human beings actually irrational? • The questions appear difficult because we’re viewing superstition in terms of the traditional opposition between rationality and superstition
The traditional opposition • Superstitions • Paradigm of irrationality • Ancient Greek philosophers • Enlightenment philosophers • Emblematic of backwardness and ignorance • Rationality • Regulative Ideal • Understood in non-physicalist terms • Consisting of universal principles • On this view tenacity of superstition facing rational criticism suggests humans profoundly irrational • Traditional view of rationality known to be problematic since David Hume
A natural phenomenon • Naturalising rationality • Placing reason in its evolutionary context (Konrad Lorenz) • Moving away from ignorance • Pragmatic considerations central • Bounded rationality (Herbert Simon) • Bounded epistemic/cognitive abilities • Rational methods applicable in limited epistemic contexts • Naturalising superstitions • Superstition understood as an evolved trait • Closely related to Dennett’s project of understanding religious beliefs as a natural phenomenon
Evolutionary explanation • Evolution gives a range of mechanisms for explaining the persistence of superstitions • Adaptive value • By-product • Lacking adaptive value • Linked to an adaptive trait • Superstitions do not have to be all explained using the same mechanisms • Thesis: (Some) superstitions are the by-product of our limited cognitive capabilities • To explain, necessary to discuss cognitive illusions
Perceptual / cognitive illusions • Perceptual illusions • Caused by applying general heuristics in inappropriate contexts • Evidence for how our perceptual processes work • A by-product of perceptual heuristics • Cognitive illusions • Caused by applying general heuristics in inappropriate contexts • Evidence for how our cognitive processes work • A by-product of cognitive heuristics • Possible explanation for (some) superstitions • Good excuse to present some interesting examples
Perceptual illusions - examples • http://www.lottolab.org/Illusions page.html
Cognitive illusions - examples • Think of a city in northern Europe that lies directly north of the tip of the Italian ‘boot’. • London has a population of (very roughly) 10 million people. Imagine there’s a disease which 10 thousand Londoners have. You’ve just had the test for it and it came back positive. What is the percentage chance you’re actually sick if the test has a 5 % false positive chance?
What do illusions tell us? • Kahnemann/Tversky • Cognitive illusions show humans irrational • View leads to exactly the same problems as with superstitious beliefs • Assumes deductive validity is the standard for rationality • Gigerenzer • Cognitive illusions show how humans reason • Understands rationality in pragmatic/ecological terms • Investigates the effectiveness of cognitive heuristics in the contexts in which they are usually applied
Example of heuristic use Krakow / Warsaw Torun / Zielona Gora Lublin / Lodz Warsaw / Kolobrzeg Zielona Gora / Krakow Torun / Kolobrzeg Warsaw Torun Lodz Warsaw Krakow Torun • Random guessing should give 3 correct answers on average • Recognition heuristic used: If I’ve heard of it, it is probably bigger • A very effective heuristic given the structure of the data (ecological rationality) • Studied by Gigerenzer • Counterintuitive effect – less knowledge leads to better results
Research project • Could (some) superstitions be due to cognitive illusions? • Explains the persistence of superstition • Superstition is caused by the misapplication of generally effective heuristics • Explains the ubiquity of superstition • Same basic set of heuristics used by all people • Need to identify the relationship between individual superstitions and individual cognitive illusions • One of the research aims for the fellowship at the Konrad Lorenz Institute
Conclusions • Superstition • May turn out to be a by-product of rational thinking • Can not be eliminated • Can be partially counteracted by making people aware of • The heuristics they use • The limitations of these heuristics • Alternative heuristics • The limitations of those heuristics • The sciences do some of this
