If you're not changing your mind, you're doing something wrong

Intellectual humility and willingness to change one's mind based on evidence are crucial for effectiveness. Leaders and organizations should expect to be wrong, proactively seek better approaches, and abandon failing initiatives even after significant investment.

THE IDEA

IF YOU’RE NOT CHANGING YOUR MIND, YOU’RE DOING SOMETHING WRONG

David Coman-Hidy is the head of the Humane League, an organization that’s been called one of America’s most important animal rights groups.11 One thing that makes the Humane League unusual is their commitment to the premise that they’re always at least a little bit wrong. Whenever a new employee joins the organization, Coman-Hidy tells them that the Humane League isn’t defined by any particular “type” of activism. They’re not committed to any particular battle or project or tactical approach. Their mandate is to follow the evidence and do whatever it suggests is most effective at helping animals. “If we’re not doing something totally different in five years than what we’re doing now, then we failed,” Coman-Hidy says. “There has to be something better than what we’re doing right now, and our goal is to find it.”

Sometimes that means switching from one type of strategy or cause to another. In its early years, the Humane League concentrated on flashy demonstrations like picketing the homes of scientists involved in animal testing. But they found that this strategy was too alienating to be effective, and the number of animals it could save even in a best-case scenario wasn’t very high. That’s why they ultimately shifted their focus from lab animals to farm animals, and persuaded Unilever, which supplies 95 percent of the United States’ eggs, to agree to stop killing male chicks. (The standard practice in the industry is to toss newborn male chicks into a grinder, since they won’t be able to lay eggs.) That’s billions of chickens saved from a painful death.

Sometimes the Humane League’s commitment to following the evidence means abandoning an initiative that isn’t working, even if they’ve already poured a lot of effort into it. In 2014, they saw some exciting preliminary results from a program called “Meatless Mondays,” in which large schools give up meat on their cafeteria menus one day per week. Based on those initial results, they spent four months pouring most of their organizational resources into convincing schools across the country to sign up for Meatless Mondays. Unfortunately, their follow-up research revealed that the program didn’t stick, at least not without a lot of ongoing support (hiring chefs, running training programs, and so on) that they weren’t equipped to provide. Realizing it wasn’t a cost-effective strategy for them after all, the Humane League had to say, “Okay, everyone, great job—but stop what you’re doing. We’re going back to what we were doing before.”

Knowing that you’re fallible doesn’t magically prevent you from being wrong. But it does allow you to set expectations early and often, which can make it easier to accept when you are wrong. Coman-Hidy says, “My intuition is that if you bring up these biases a lot—that we are always going to think that we’re right, that we’re always thinking what we’re doing is the best and most important thing to be doing . . . it makes it an easier pill to swallow when inevitably something better comes along. Because you’ve kind of inoculated yourself against the ‘horror’ of having been suboptimal for some period of time.”

Hopefully this chapter has helped inoculate you against the “horror” of being wrong, and left you with a new attitude toward error. Discovering you were wrong is an update, not a failure, and your worldview is a living document meant to be revised. In the next chapter we’ll explore another key facet of changing your mind. Now that you’ve gotten good at being wrong, it’s time to get good at being confused.

When to use it

  • Business strategy: Regularly reassess strategic decisions using new data and be willing to pivot away from unproductive initiatives.

  • Scientific research: Practice hypothesis updating when contradictory evidence emerges, rather than defending initial theories.

  • Personal development: Accept that past choices may have been suboptimal and adapt future behaviors accordingly.

  • Team leadership: Encourage team members to share mistakes and insights without fear, modeling intellectual humility.

FROM THEORY TO EVERYDAY LIFE

In practice

01

Humane League’s Strategic Shift from Lab to Farm Animals

Initially focused on flashy protests against animal testing labs, the Humane League realized that approach was alienating and not cost-effective. They shifted focus to farm animals, ultimately persuading Unilever to end the killing of male chicks, saving billions of chickens.

02

Meatless Mondays Program Pivot

After seeing promising preliminary results, the Humane League invested heavily in promoting Meatless Mondays in schools. Follow-up research showed the program required ongoing support beyond their capacity, so they abandoned the initiative despite sunk costs, returning to previous strategies.

A MOMENT TO REFLECT

Put it to work.

  1. When was the last time you changed your mind about a strongly held belief? What evidence prompted that change?

  2. In your organization, are failures or course corrections celebrated as learning opportunities? How could you foster a culture that embraces updating strategies based on data?

  3. How might you proactively ‘inoculate’ yourself against the discomfort of being wrong, as Coman-Hidy suggests?
