Understanding, defining and measuring the trait of superstition Éva Delacroix, Professor Valérie GUILLARD PhD student
What is superstition? • Beliefs or behaviors that are contrary to rational norms within a specific society (Campbell, 1996) • Confusion around this concept: frontiers between superstition, the paranormal, witchcraft or religion are vague. • Superstitions are culturally anchored by members of a given society • In China, prices ending with the digit 8 are very common (local belief that number 8 brings luck, prosperity and happiness) (Simmons and Schindler, 2002). • Aim of this research: • clarify the definition and the dimensions of superstition • Propose the adequate measurement scale
What is superstition? (continued) • Superstition beliefs rely on a mistaken causal link between two phenomena that, from a rational standpoint have nothing to do with one another. • Primitive superstition is related to true beliefs: people in Middle Age truly and deeply believed that crows brought bad luck(Skinner, 1948 ; Staddon and Simmelhag, 1971 ; Devenport and Holloway, 1980)
What is superstition? (continued) • Modern superstition: • People says « It’s a very old ritual, I know it’s absurd, but… » (qualitative research) • People do not believe in the existence of a mistaken causal links between two events (cross the finger and to pass an exam). But they practice some rituals. • Half belief (Campbell, 1996): people adopt superstitious behaviors without deeply believing in them. • They are reluctant to say they really believe in the validity of superstition BUT they are reluctant to say the do not believe in it.
What is superstition? (continued) • Superstition gives the illusion of control(Langer, 1975, 1977) • Superstitions are used to fight anxiety by filling the psychological gap caused by uncertainty(Malinowski, 1948) • Superstitious thoughts or behaviours are used as a substitution to instrumental acts that people would have liked to achieve in order to influence the situation
Measure of superstition • Need for a reliable and valid measurement scale of supersistion • When you ask people if they are supertitious “No”. • People are reluctant to admit their irrational beliefs, even if they have such irrational thoughts or practices. • What are the variety of superstitions behaviours? • Lack of such measure in the literature • 2 dimensions measure superstition (Jahoda, 1969 ; Wiseman and Watt, 2004) • Definition of superstition • Superstition consists in unfounded half-beliefs that certain facts (external uncontrollable events or internal actions) or objects can • carry good or bad luck, or • be omens of futur positive or negative events.
Measure of superstition (continued) • Study 1 • Exploratory qualitative study (N=52 students, aged 23 years) • “Do you have some rituals which bring you good luck” • “Before a stressful event (competition, exams, etc), do you have some rituals to move the bad luck away?” • “Are you superstitious?” • List of superstitious beliefs and behaviours • Study 2 • Psychometric scale development procedures: Test of a large pool of items • Sample 1 : 150 french business students (45 items) • Sample 2 : 119 french business students (32 items) • Sample 3 : 215 french non student individuals (27 items)
Measure of superstition (continued) • Items of practice and beliefs are highly correlated (r > 0,8) • We only kept the belief formulated items • When I see a black cat I turn my way • Black cats carry bad luck • 24 items measure superstition with 5 dimensions • 60 % variance explained
Discussion Contributions • 5 dimensions conceptually interesting for a better understanding of superstition • Existing scales not relevant: they only measure popular belief superstitions Limitations • Fate and signs: dimension inside our definition? • Related to external locus of control whereas others dimensions related to internal locus of control (by respecting some mental rules, I can control the world) • Violation of normality, most people exhibit low scores • How can we take the distribution asymetry into account? • Scale developped in France and might not be applied in other cultures
Discussion(continued) • Relevance in literature • Superstition and marketing • In the USA, between 800 and 900 millions dollars are lost in business of each Friday the thirteenth because people do not want to go to work (Kramer and Bloke, 2008) • Beijing Summer Olympic games are scheduled to open on August 8, 2008 at 8 PM Thank you for your attention !!!
