Blame your inclination towards chocolates and hybrid cars to your genes, says a new study, which found that clues to consumer behaviour may be lurking our genes.
"We examine a wide range of consumer judgment and decision-making phenomenon and discover that many-though not all of them-are in fact heritable or influenced by genetic factors," said authors Itamar Simonson (Stanford University) and Aner Sela (University of Florida, Gainesville).
The authors studied twins' consumer preferences to determine whether or not certain behaviours or traits have a genetic basis.
The authors discovered that people seem to inherit the following tendencies: to choose a compromise option and avoid extremes; select sure gains over gambles; prefer an easy but non-rewarding task over an enjoyable challenging one; look for the best option available; and prefer utilitarian, clearly needed options (like batteries) over more indulgent ones (gourmet chocolate).
They also found that likings for specific products seemed to be genetically related: chocolate, mustard, hybrid cars, science fiction movies, and jazz.
The researchers also found that some tendencies did not seem to be heritable-for example, a preference for a smaller versus larger product variety or likings for ketchup and tattoos.
"The current research suggests that heritable and other hard-wired inherent preference components play a key role in behavior and deserve much more attention in marketing and decision-making research," the authors write.
The authors believe their work may reveal some important information on the genetics of "prudence."
"Some people may be born with a tendency to 'be in the mainstream' whereas others tend to 'live on the edge," concluded the authors.
The study has been published in the Journal of Consumer Research.
