Emotion in Political Judgment

It’s been obvious to everyone who’s written about politics since Aristotle that emotion plays an important role in political rhetoric and political judgment. With an increased focus on emotion in cognitive scientists, there has been a flourish of empirical work attempting to elucidate this role. I thought it might be interesting to say a little about this given the recent resurfacing of the Westen et al. study on motivated reasoning in politics. While the recent posts on the study have (unfortunately) described it in terms of confirmation bias, it would be more accurate to describe the study, and motivated reasoning in general, as emotion-driven or emotion-influenced reasoning. What the Westen et al. study showed, for example, is that brain areas associated with emotion were activated when partisans were faced with information that threatened to undermine the conclusion they wanted to reach.

When the study first surfaced (before it had even been submitted for publication! it was that sexy), much of the discussion centered on how irrational the partisans in the study looked, because they relied on emotion instead of (or in addition to) reason. This perceived opposition between emotion and reason is certainly not new, and some empirical results bare it out. For example, people tend to attach emotional reactions to entire groups, and that emotion then influences their judgments about individual members of that group. When people who have a strong dislike for Democrats hear a Democratic politician speak, their negative emotions associated with the Democratic party are likely to lead to negative evaluations of the politician, her speech, and any positions she takes in the speech1. Furthermore, some emotions (e.g., anger) may even make people use less effort, and thus simpler processes, to arrive at a political judgment2. I probably don’t need to tell you how much anger opposition parties can elicit in partisans (if I do need to tell you, then go read a political blog). So emotion can decrease the efficiency with which we make political judgments.

But the relationship between emotion and reasoning, and therefore emotion and political judgment, is much more complex than the common view that emotion is detrimental to reasoning. As neuroscientists like Antonio Damasio have shown, individuals with damage in the emotional centers of their brains have a very difficult time making rational choices3, largely because they don’t have emotions to make sure they make choices that aren’t harmful. In addition, we can sometimes account for our emotional reactions to information while making decisions. For example, our goals influence the role that emotion plays in our decision making. Research on motivated reasoning (upon which the Westen et al. study was based), for example, has repeatedly shown that if we’re motivated to reach a true conclusion, as opposed to being motivated to reach a specific conclusion, we are able to overcome our emotional reactions to particular pieces of information a large extent.

As a further example of this complex relationship in politics specifically, I thought I’d describe a study on emotion and political judgment by Isbell and Wyer4, which serves as an excellent example, and should help rehabilitate the reputation of partisans a bit. Isbell and Wyer note that emotions can affect judgments, even when the emotions are unrelated to the judgments. So, for example, being in a bad mood because of, say, the weather, can lead to negative judgments about things unrelated to the weather, while positive moods can lead to positive judgments about unrelated things. In their study, participants were first told to write a story about a personal experience that either made them happy or sad. Immediately afterwards, they were presented with a newspaper article the described a political candidate and his or her political positions. Half of the participants were told either to evaluate the candidate as they read the article, in order determine whether they would vote for him/her (candidate-evaluation condition). In this condition, participants were thus motivated to evaluate the candidate. The other half of the participants were told to evaluate the article itself to determine whether it was well-written (article-evaluation condition. These participants had no “extrinsic” motivation to evaluate the candidates. Finally, half of the participants rated how favorable they found the candidate, and whether they would vote for him, immediately after finishing the article, and the other half did so after 24 hours.

There are several interesting comparisons in this design. Participants were either happy or sad, either “extrinsically” motivated (candidate-evaluation condition) or unmotivated (article-evaluation condition), and made their evaluation of the candidate either immediately or 24 hours after reading the article. Furthermore, participants were divided into partisans or nonpartisans based on the strength of their identification with a specific political party. Partisans tend to be more interested in politics, and thus should be more “intrinsically” motivated to evaluate the candidates, regardless of whether they were in the candidate or article-evaluation conditions. Based on the motivated reasoning literature, we would expect that since the emotions participants are experiencing (happiness or sadness) are unrelated to the information they read about the candidates, motivated (extrinsically or intrinsically) should attempt to discount the emotions when evaluating the candidates.

Their results were consistent with this prediction. In fact, motivated participants actually overcompensated for their irrelevant emotions. Both partisans and nonpartisans in the candidate-evaluation condition, and partisans in both evaluation conditions, gave the candidates more positive evaluations when they were sad, and less positive evaluations when they were happy. Nonpartisans in the article-evaluation condition, however, were influenced by the irrelevant emotions, and thus rated candidates as more negative when they were sad and more positive when they were happy. There were no differences between the evaluations made immediately and those made 24 hours later, indicating that participants’ initial judgments, whether they were born of the irrelevant emotions or from overcompensating for those emotions, stuck. The data in the figure below is compiled from both the immediate and delayed evaluations (p. 245).

There you have it: motivated participants recognized that their emotions could influence their judgments, and because those emotions were irrelevant, compensated for them. Granted, they overcompensated, but they didn’t let irrelevant emotions get in the way. Partisans in particular were able to avoid being misguided by irrelevant emotions, regardless of whether they completed a task that motivated them to do so. So, in a way, partisans were less irrational than nonpartisans. Does this mean that partisans always make more rational political decisions than nonpartisans? Obviously not, as the Westen et al. data shows, but it does show that the relationships between rationality, partisanship, and emotion are far from straightforward, and we can’t make a judgment about any of them based on one study. From these two studies combined, a better conclusion might be that partisans are too beholding to their biases and prejudices, while nonpartisans are too fickle and open to irrelevant situational influences. Which is better?

    Wait, I’m confused (and let me acknowledge that I’m speaking from a rank amateur’s perspective, though I love reading this blog and find these kinds of topics fascinating). Did partisans “consciously” recognize their emotions and overcompensate or “unconciously” (sorry for the lack of precise terminology)? Is it not possible that partisans are semi-deliberately ignoring their emotions-as-signals (perhaps they assume that listening to one’s emotions makes one less rational)and that the effort to ignore those emotions makes their thinking more rigid and partisan rather than truly rational?

    In other words, if we allow ourselves to be aware of the signals our emotions are sending to our “conscious” mind (again, apologies for not knowing more precise terminology) and only then choose to exert control, “consciously” rather than “unconsciously,” wouldn’t that be the best way to achieve rational decision making? As opposed to either simply acting on our emotional impulses *or* suppressing our emotional impulses and acting on pre-scripted beliefs (in which case you are not using your rational powers, you are simply disciplining your emotions without adding the step of thinking your way through the position).

    In other words, emotion, if unchecked by rational thought, can decrease the efficiency of our judgement, political or otherwise, but if emotion is only “checked” unconsciously or dogmatically, this also prevents true rational thought. Wouldn’t true rational thought be allowing oneself to be aware of one’s emotions, and then using the “rational” part of the brain to assess the accuracy of those emotions-as-signals and decide whether to act in accordance with those emotions or not in accordance?

    Does that make any sense?

    Ada,

    Well, it’s unlikely that partisans are consciously accounting for their emotional state, though it’s not impossible. What’s important to remember, though, is that in the experiment I described, the emotional state they were experience was irrelevant to the political judgment. So it wouldn’t be more rational not to ignore it, and there’s no a priori reason to think that ignoring it consciously is better than ignorining it unconsciously.

    Instead, the picture the Westen et al. study combined with the study described in this post paint is one in which everyone’s political judgments are likely to be influenced by emotions. Partisans are likely to be influenced by emotions that result from the desire to reach a specific conclusion, while partisans can be influenced by situationally-induced emotions that have nothing to do with politics.

    ada: If you’re fascinated by this topic, I’d recommend How We Know What Isn’t So by Gilovich (http://www.amazon.com/gp/product/0029117062).

    I’m realizing now that I was lumping the two studies (the Westen and the Isbell/Wyer) together in my head as I was writing my comment—sorry about that! I suppose what I was thinking about was that I don’t see overcompensating for emotions to be truly unemotional thinking—-in other words, perhaps it is not only the partisan’s pre-conceived judgement that is emotional; perhaps his reacting so strongly “against” the emotion is emotional as well. At the same time, I wonder, theoretically, if one made oneself aware of the fact that the sadness was likely to affect one’s judgement, one might then be able to compensate rather than overcompensate. Or, um, something like that.

    Thanks for the book recommendation!
