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!
