Are facts enough to change someone’s mind? How to change someone’s mind?
At a dnner party, three people debate a puzzle – but beneath it lies a deeper question: are facts for changing someone’s mind? Understanding how logic, belief, and trust interact can reveal why even solid evidence often fails to persuade.
Take a moment to think about it. Most people say there’s not enough information to tell, but they’re wrong. Linda is either married or not, no other option. So in both cases, someone married is looking at someone single. When shown the explanation, most people accept it, even after answering confidently before.
A 2005 study by Brendan Nyhan and Jason Reifler looked at American views on the Iraq War. Researchers showed participants a news article proving no WMDs were found. Yet many still believed they were—and became even more convinced. Classic experiments found that factual corrections often fail to shift entrenched beliefs, see When Corrections Fail (Nyhan & Reifler, 2010) for details
If you want a practical framework to evaluate claims before reacting, here’s how to improve your critical thinking in five steps.
So why do arguments change people’s minds in some cases and backfire in others?
Arguments work better when they consider what people believe, who they trust, and what they value. Logic puzzles like the dinner example work because, even with different answers, people start from shared assumptions.
In 1931, a young mathematician named Kurt Gödel proved that a fully complete mathematical system was impossible. Though it overturned decades of work by Russell and Hilbert, the proof was accepted because it used axioms everyone agreed on.
When Beliefs and Trust Override Pure Logic
Of course, many disagreements involve beliefs that can’t be reconciled through logic. When they depend on outside information, it often comes down to which sources people trust.
One study asked people to estimate several statistics related to the scope of climate change. Participants were asked, “How many years between 1995 and 2006 were among the 12 hottest since 1850?” After providing their answers, they were presented with data from the Intergovernmental panel on Climate Change, in this case showing that answer was 11 of the 12 years. Receiving reliable statistics from a trusted source made people more likely to accept that the earth is warming.
How Values Shape the Way People Accept Facts
Finally, when facts can’t settle a disagreement, persuasion may rely on the audience’s values. For example, researchers have conducted a number of studies where they’ve asked people of different political backgrounds to rank their values. Building trust starts with listening; active listening improves persuasion by lowering defensiveness and opening people to new information.
Liberals in these studies, on average, rank fairness–here meaning whether everyone is treated in the same way–above loyalty. In later studies, researchers attempted to convince liberals to support military spending with a variety of arguments. Arguments based on fairness–like that the military provides employment and education to people from disadvantaged backgrounds–were more convincing than arguments based on loyalty–such as that the military unifies a nation.
These three elements–beliefs, trusted sources, and values – may seem like a simple formula for finding argument and consensus. Our instinct is to form arguments that reflect our own beliefs, sources, and values. Even when we try not to, it’s hard to see what matters to those who disagree with us.
The best way to find out to simply to talk to them. In the course of discussion, you’ll be exposed to counter-arguments and rebuttals. These can help you make your own arguments and reasoning more convincing and sometimes, you may even end up being the one changing your mind.
