Most people think they are open-minded and would like others to perceive them as such. But for the things that matter most—religious beliefs, for example, or the meaning of life—few of us are genuinely willing to consider that we might be wrong, let alone do the hard work of revising beliefs. At a fundamental level, we humans are somewhat closed-minded.

As a social psychologist, I research big questions, such as what makes life meaningful and the nature of humility. I've had a long-standing interest in why people are so resistant to changing their cherished core beliefs. After all, isn't it better to remain open-minded when you may be wrong or can't know for certain?

As decades of research have revealed, it turns out that our deepest convictions serve important psychological functions that make them hard to change. It's unsettling to admit that our core beliefs about how the world works may be wrong.

I call that openness "existential humility": a willingness to change our minds about our deepest convictions when presented with new evidence. And though holding beliefs in this way can be difficult, it can also be a bridge to creating stronger relationships and more inclusive communities.

Power of worldview
All of us hold myriad beliefs that range from the mundane to the magnificent. "Is pineapple a legitimate pizza topping?" is very different from "Is there life after death?" Yet these seemingly disparate beliefs are connected through an interlocking set of ideas and principles that help us make sense of ourselves and the world around us.

Psychologists call these sets of beliefs "worldviews," and they provide people with a sense of meaning in an otherwise confusing and chaotic world. They are a constellation of beliefs that shape what people value, view as important and perceive as morally right and wrong.

It's natural to take worldviews for granted, assuming that other intelligent people see the world the same way.

At the core of these worldviews are your most cherished beliefs: who you are, what the meaning of life is, what constitutes right and wrong. Ask yourself how willing you are to revise those beliefs. How sure are you that you are right? What would it take to alter those convictions?

Probably a lot.
