Harvard Professor: Never Say 'I Disagree' to Change Minds

Trying to change someone's mind by telling them they're wrong is like trying to open a door by pushing harder when it says "pull."

Dr. Alison Wood Brooks, a Harvard Business School professor who studies conversation and emotion, has spent years researching why persuasion fails. She's discovered something surprising: the moment we say "I disagree," we've already lost.

The problem lies in how our brains work. When someone challenges our beliefs, even with undeniable facts, we don't reconsider our position. We double down on it harder than before, a phenomenon psychologists call the backfire effect.

Dr. Brooks shared her solution on the Diary of a CEO podcast with Steven Bartlett. The key is simple: don't invalidate people, even when they're completely wrong.

"The only way that we change our beliefs is usually across many conversations and we're around someone we like talking to and respect and have admiration for," Dr. Brooks explained. "And then over time, we sort of bend to the gentle pressure of their differing viewpoint."

Her approach comes from Harvard and University of British Columbia research called the "receptiveness recipe." Instead of stating disagreement upfront, she recommends three strategies that keep dialogue alive.

First, admit uncertainty. Even when you're certain you're right, acknowledge that the goal isn't winning the moment. It's keeping the conversation emotionally safe enough to continue.

Second, hedge your claims and validate their feelings. If someone says something you know is incorrect, respond with curiosity instead of correction. Try "That's interesting, I'd love to hear more" or "As someone who knows a bit about this topic, that's intriguing."

Third, save your disagreement for later. Dr. Brooks wrote a chapter in her book called "Do Not Disagree" specifically about this approach.

"It can come later, but first has to come like 'Oh, it's so intriguing that you said that. I'm so fascinated, and it makes sense that you might feel that way. I wonder if…' and then you can go on instead of 'I disagree,'" she explained.

Many people see this as weakness or avoiding the truth. But Dr. Brooks argues it's actually strategic. You're not abandoning your position, you're creating space where the other person might actually listen to you.

Why This Inspires: In a world where everyone seems entrenched in their views and shouting matches replace real conversation, this research offers genuine hope. It shows that changing minds is possible, we've just been going about it all wrong. By choosing connection over correction, we can have the kind of meaningful conversations that actually move people toward new understanding.

The approach works because it addresses a fundamental human need: we all want to feel heard and respected. When someone validates our perspective before sharing theirs, we naturally become more open to what they have to say.

Dr. Brooks reminds us that persuasion isn't a sprint, it's a marathon that happens across many conversations with people we trust and respect.
