An Argument for Less Debate

In addition to sparking my passion for psychology, Seeds of Peace became an eventual research partner. In one recent paper, my coauthors and I explored the relationships that form at this camp. In general, we find that campers were more likely to form connections with those who shared their nationality. In other words, those who were part of their in-group rather than those in the out-group. This is consistent with lots of evidence showing the power of similarity, or what we call homophily: liking people who are like you.

But remarkably, when we specifically examined the relationships that formed among campers who shared a dialogue group, the pattern fully reversed. Campers were more likely to form relationships with out-group members in their dialogue group than in-group members.

Let that result sink in. This means that a Jewish Israeli camper was more likely to become close with a Palestinian camper in his dialogue group than with another Jewish Israeli in that group. And likewise, a Palestinian was more likely to become close to a Jewish Israeli in the group. I don’t know that there is another finding that I could share that would better highlight the remarkable power of dialogue.

Now, imagine instead that the Israeli and Palestinian campers engaged in two hours of debate every day for three weeks. I feel quite sure that we would not see those same relationships form.

We couldn’t test that hypothesis at camp, of course, but we could in the lab. There, we randomly assigned pairs of participants who disagreed about an issue to have a conversation in which they were instructed to focus on either demonstrating why they were right or sharing and learning about each other’s perspectives.

For a task with an objective right answer—choosing the best candidate on paper to hire—we find that pairs were more likely to get the correct answer when engaging in dialogue. When the interaction was an online chat, we find that participants were more satisfied and felt more included in dialogue than in debate. Those in the dialogue condition also had a more accurate understanding of their partner’s perspective.

What about persuasion? Did those in the debate condition manage to convince each other that they were right? No. If anything, participants seemed to change their opinion more after engaging in dialogue. Thus, these initial findings suggest that dialogue can improve objective decision-making, subjective experience, and understanding.

Given the apparent benefits from engaging in dialogue, we also wanted to understand what leads people to approach disagreement in a more debate-like or dialogue-like way. We find that when pairs more strongly disagreed about an issue and when individuals felt more certain of their own opinion, they were more likely to engage in debate and less likely to engage in dialogue. Participants were more likely to engage in dialogue, however, when they perceived that they shared goals and values with the other person.

With these findings in hand, I’d like to highlight three things we can all do to encourage more productive disagreement:

First, be humble. We need humility to recognize that we haven’t figured everything out yet. When we have humility rather than certainty, we can make space for other good ideas and perspectives.

Second, adopt and pursue learning goals in both our personal and professional lives. When we pursue learning goals, we can put winning aside—at least sometimes—and instead focus on growing and improving. With a learning and growth mindset, we are better prepared to learn from successes as well as failures. We are free to make mistakes and admit to them because we recognize that we are a work in progress just like everyone else is.

Finally, be intentional. There’s something powerful that comes from recognizing our default patterns. Once we know that people tend to connect more easily with those who are similar and that people are more likely to start a debate with those who seem different, we can intentionally disrupt our default patterns. If we’re intentional about learning, and especially if we’re intentional about learning from people who have different perspectives, we’ll be in the best position to capitalize on all of the best ideas and continue to grow.

To foster dialogue, then, we should embrace humility, prioritize learning, and intentionally look for opportunities to understand and appreciate those who are different. If we can all engage in a little more dialogue and a little less debate, I believe the marketplace of ideas will grow more vibrant—and more people will want to spend more time shopping there.
