Researchers at the University of California Santa Barbara set out to test this possibility. They hypothesized that there is a deep-seated perception of science as a moral pursuit — its emphasis on truth-seeking, impartiality and rationality privileges collective well-being above all else. Their new study, published in the journal PLOSOne, argues that the association between science and morality is so ingrained that merely thinking about it can trigger more moral behavior.
The researchers conducted four separate studies to test this. The first sought to establish a simple correlation between the degree to which individuals believed in science and their likelihood of enforcing moral norms when presented with a hypothetical violation. Participants read a vignette of a date-rape and were asked to rate the “wrongness” of the offense before answering a questionnaire measuring their belief in science. Indeed, those reporting greater belief in science condemned the act more harshly.
Of course, a simple correlation is susceptible to multiple alternative explanations. To rule out these possibilities, Studies 2-4 used experimental manipulations to test whether inducing thoughts about science could influence both reported, as well as actual, moral behavior. All made use of a technique called “priming” in which participants are exposed to words relevant to a particular category in order to increase its cognitive accessibility. In other words, showing you words like “logical,” “hypothesis,” “laboratory” and “theory” should make you think about science and any effect the presentation of these words has on subsequent behavior can be attributed to the associations you have with that category.
