Psych in Sum: Low information voter or cognitive miser?

With the presidential election less than a month away, the pressure is on for Hillary Clinton and Donald Trump to pick up as many undecided voters as they can before November 8th. But how do voters decide who they are voting for and what kinds of information do they consider? David Redlawsk sheds some light on the process.

The ideal way to make this important decision is through a thorough information search that considers all attributes of all possible candidates. However, most people don’t do this, because, well, our brains are lazy. Instead, we develop various information search strategies in deciding who to cast a ballot for. Behavioral Decision Theory suggests that people tend to settle for “good enough” choices once they feel like they have acquired enough information about the decision. We are “cognitive misers,” in the way that we don’t expend cognitive energy when we don’t have to. There tend to be two sets of conditions under which people make decisions between alternatives; compensatory rules, where alternatives are compared on all attributes such that a low score on one attribute may be redeemed with a high score on another attribute, and non-compensatory rules, where people consider each alternative on one attribute in serial and discard inadequate options immediately.

In situations where decisions can be made easily, people are more likely to employ compensatory decision rules, but in situations that are more complex, people tend to go with a single-elimination non-compensatory system. Further, he found that voters who used compensatory rules had more realistic views of the candidates, including lower evaluations of their preferred candidate and high evaluations of rejected candidates than people who use non-compensatory rules. Single issue voters, like people who vote based only on a politician’s stance on gun rights or abortion, are using non-compensatory rules, and the narrowness of their decision-making process leads to worse decisions. It’s always better to have more information than less!

Self-Control and Eating: Which counts more, health or taste?

Could the time it takes you to process taste- and health-related characteristics of food predict the final food decision you’ll make? A study recently published in the journal Psychological Science1 would suggest so. The study examined the hypothetical food decisions of 28 male and female undergraduates using a mouse tracking task, which captured both the time and trajectory of participants’ decisions. See image below of the task and sample trajectory results.

The researchers suggest that the earlier a factor like taste is processed while making a decision, the more heavily weighted that factor will be in someone’s final decision. Health-related attributes (e.g. calories), on the other hand, are delayed in the decision-making process and won’t be as strongly considered in the decision-making process. For example, someone low in dietary self-control who has a weak spot for gooey fudge brownies will immediately think about how delicious and sweet the brownies will be rather than their relative unhealthiness, and this deliciousness factor will be the strongest and loudest factor when that person decides whether to eat the brownies. Knowing this, no one is surprised when the brownies win the majority of the time.

In contrast, participants high in self-control processed tastiness and healthiness at approximately the same time, making both attributes relatively balanced when making a food decision, which may explain why those high in dietary self-control are more often successful when trying to exert self-control in a food situation.

Based on these findings, the researchers suggest the following implications:

  1. Delaying a food decision, even by a small waiting period, may be enough time to allow health factors to influence a final decision more strongly
  2. Interventions that can increase speed with which health information is processed may improve dietary self-control.
  3. Marketing strategies that display health attributes more prominently may promote faster processing of health attributes
