How messages about behavioral genetics research can impact on genetic attribution beliefs

Science communication has the potential to reshape public understanding of science. Yet, some research findings are more difficult to explain and more likely to be misunderstood. The contribution of this paper is threefold. It opens with a review of fascinating interdisciplinary literature on how scientific research about human genetics is disseminated in the media, and how this type of information could influence public beliefs and world views. It then presents the theoretical framework for my research program, providing a logical basis for how messages about human genetics may influence people's beliefs about the role of genes in causing human traits. Based on this reasoning, I formulate the genetic interpolation hypothesis, which predicts that messages about specific research findings in behavioral genetics can lead members of the public to infer greater genetic causation for other social traits not mentioned in the content of the message. While this framework offers clear, testable predictions, some questions remain unaddressed. For instance, what kind of message formats are persuasive enough to alter people's views? The third contribution of this paper is to begin to address this question empirically. I present the results of a survey experiment that was designed to test whether a simple, short paragraph about behavioral genetics is a powerful enough stimulus to cause the genetic interpolation effect.
