          Abstract

          The present study investigated the effects of communication styles, source expertise, and audiences’ preexisting attitudes in the contexts of the debate regarding genetically modified organisms. A between-subject experiment ( N = 416) was conducted manipulating communication styles (aggressive vs. polite) and the expertise of the communicator (scientist vs. nonscientist) in blog articles. The results showed significant effects of communicator expertise and individuals’ preexisting attitudes on writer likability and message quality, depending on the communication style used. Expectancy violation was found as a significant mediator that explains the differences. These findings provided a plausible explanation for the way in which communication styles work in science communication contexts and offered practical implications for science communicators to communicate more strategically.

            The case for motivated reasoning.

            Ziva Kunda (1990)
            It is proposed that motivation may affect reasoning through reliance on a biased set of cognitive processes--that is, strategies for accessing, constructing, and evaluating beliefs. The motivation to be accurate enhances use of those beliefs and strategies that are considered most appropriate, whereas the motivation to arrive at particular conclusions enhances use of those that are considered most likely to yield the desired conclusion. There is considerable evidence that people are more likely to arrive at conclusions that they want to arrive at, but their ability to do so is constrained by their ability to construct seemingly reasonable justifications for these conclusions. These ideas can account for a wide variety of research concerned with motivated reasoning.
