Research has recently begun to document just how common and ordinary such superstitious or magical thinking is among people. Superstitions are beliefs that run counter to rational thought or are inconsistent with known laws of nature. While many superstitions are culturally shared and socially transmitted from generation to generation, others consist of relatively more idiosyncratic beliefs or rituals, like the examples described previously. My colleague Tom Kramer and I study how peoples’ superstitious beliefs influence their behavior as consumers. For example, common superstitions among Taiwanese include beliefs about lucky colors (e.g., red) and lucky numbers (e.g., 8). In research Tom and I conducted in Taiwan, we found that Taiwanese consumers are more likely to purchase a product that is red than the same exact product in another color, and purchasers have higher expectations for the red product than for, say, a green product. In other words, consumers expect the red product to work better than the green one and would be more upset if the product failed or broke. Our research also demonstrated that Taiwanese consumers are willing to pay a higher price for a package with a “lucky” number of items inside (8 tennis balls) than the same package with a greater but neutral number of items (10 tennis balls). Taiwanese consumers were willing to spend over 50 percent more for 25 percent fewer tennis balls because of their positive superstitious beliefs regarding the number 8 (versus 10). Similarly, we found that Taiwanese consumers are willing to pay more to avoid unlucky numbers. They would rather pay TW$555 (5 is a neutral number) than TW$444 (4 is an unlucky number), foregoing a discount for the same product.
