Straighten up and fly right: Making dialogue work

Does dialogue work to harmonise conflicting views, or does it simply entrench differences? According to extensive research in the psychology of polarised opinion, the answer is discouraging: when people of any ideological stripe encounter opposing views and evidence, their beliefs grow even more divergent.1 Hearing from the other side seems to make people double down on their original positions. The Oatmeal’s compelling comic You’re Not Going to Believe What I’m About to Tell You explains the friction involved in changing beliefs:

Why do we not only ignore evidence counter to our beliefs, but dig our heels in deeper and believe more strongly in the opposing argument? Why would providing more evidence make someone less likely to believe in an idea? It’s called the backfire effect, and it’s a well-documented psychological behaviour. It makes us biologically wired to react to threatening information the same way we’d react to being attacked by a predator. It’s a biological way of protecting a worldview.

The backfire effect is a source of frustration for those of us dedicated to fostering understanding in an ideologically divided world. If coming face to face with contrasting positions makes people simply hunker down, it’s a dead-end strategy. But the alternative is equally unpromising: if people remain in their respective echo chambers, cut off from opposing points of view, they’ll develop a sense of ‘false consensus’ –– an assumption that everyone shares their own views –– and they’ll never recognise (much less admit to) the possibility of being wrong.

We’re in quite a predicament, caught between the Scylla of defensive self-justification, and the Charybdis of blind mutual reinforcement.

It’s hazardous –– but it’s not hopeless. We can open ourselves to different points of view, and help others do the same; we just need to cultivate the right dispositions. We need to want to escape our echo chambers, and we need to want to engage constructively with people who may appear to be our adversaries. Here are some avenues for motivating these powerful desires –– and for overcoming the indifference, stubbornness, credulity and complacency that might otherwise stymie our attempts:

    1. Cherish rigorous thinking, and recognise that learning to reason and communicate better are valuable pursuits that are worthy of sustained effort.
    2. Be curious about other points of view. No matter whether your ultimate goal is to interrogate your own views or to persuade someone else, sincere enquiry is one of the most effective strategies. Kal Turnbull, founder of the Change My View subreddit, observes that success begins with “asking questions in a really productive way… genuinely trying to understand, first and foremost, what’s being said… [Y]ou should always start with the questioning, because either you learn enough to change your [own] view, or you learn enough to change [the other person’s] view.”
    3. Be open-minded, that is, be critically receptive to alternative possibilities, ready to consider them with fairness and impartiality, and inclined to follow arguments where they lead. Equally, be open to criticism, take new evidence into account, continually reassess the balance of evidence, and be willing to concede your claims or even your entire position.
    4. Be sceptical and discerning: habitually seek evidence, examine warrants and test arguments. Similarly, be vigilant about the assumptions and biases that might distort your own and others’ thinking. Bear in mind William James’ observation: “A great many people think they are thinking when they are merely rearranging their prejudices.”
    5. As the above points suggest, be self-correcting: humble enough to recognise your own fallibility, and courageous enough to act on it. Peter Ellerton puts it like this: “Embrace when you are wrong, explain why you might have come to the wrong conclusion and celebrate the fact that you are in a better position than before.”
    6. Make opportunities to think collaboratively in a group setting, in which each participant is responsible for making their thinking accountable to the others, and each stands to benefit from the others’ insights. To quote Peter Ellerton again, we need “a range of dispositions which make us want to not just make our position clear to others, but to make our reasons clear to others. If we don’t take the trouble to try and make the reasoning that is sensible to us also accessible and meaningful to other people, then that’s not public reasoning, it’s just a different kind of assertion.”
    7. De-escalate confrontation. Barry Lam points out that there’s a stronger tendency for dialogue to increase polarisation of opinion if the encounter is hostile or combative. If we hope to find common ground, we need to find ways of defusing aggression and promoting civility and respect.
    8. Take charge of your learning by understanding the purpose of enquiry and argument, and reflecting metacognitively on how you use these methods. Deanna Kuhn makes clear just how high the stakes are here:

    People who know how they know all that they know to be true are in control of their own knowing. They understand what support must be in place to justify a claim and what kinds of counterevidence disprove it. They are thus open to change of belief in the face of new evidence and argument, but their beliefs do not fluctuate in reaction to every new influence. To be in control of their own knowing and thinking may be the most important way in which people, individually and collectively, take control of their lives.


    Postscript, 12/12/2018

    Thanks to Andrew Withy for drawing my attention to a number of studies indicating that the validity of the backfire effect has been called into question.

    One replication study suggests that it may occur only under certain conditions, and that its effect size may not be as great as was initially supposed.

    Another experimental study found that “that backfire is stubbornly difficult to induce, and is thus unlikely to be a characteristic of the public’s relationship to factual information. Overwhelmingly, when presented with [corrective] factual information … the average [person] accedes to the correction and distances himself from the inaccurate claim.”

    A third paper, reporting on further empirical research, notes that prior studies “have reached conflicting conclusions about people’s willingness to update their factual beliefs in response to counter-attitudinal information” and that while some research supports the backfire effect in finding people “highly resistant to unwelcome information… other studies find that fact-checks or other forms of corrective information can partly overcome directionally motivated reasoning and reduce misperceptions”. For example, during the 2016 US presidential campaign, when misleading claims made by Donald Trump were corrected, this reduced belief in those claims even among Trump supporters. (Interestingly, attitudes toward Trump were not affected, suggesting that “corrective information can reduce misperceptions, but will often have minimal effects on candidate evaluations or vote choice”, and more generally, that “people may be willing to update their factual beliefs while interpreting the facts in a belief-consistent manner”.)
