Blinded By Certainty

Have you ever looked back on a situation and thought, how did I believe that so completely? Where did that story even come from? Most of us have had moments where we were convinced we were seeing things clearly, only to realize later that our view missed the mark. When we’re immersed in an experience, we tend to assume our thoughts, feelings and conclusions are accurate and reliable. We believe we’re seeing clearly, thinking logically and responding to reality.

But often, we’re responding to our version of reality because the human mind isn’t a neutral recording device. We don’t just take in facts; we filter them through our history, beliefs, fears, and emotional habits, editing the information as we go.

This is a cognitive bias, a pattern of thinking that shapes how we interpret information, often without our realizing it. These biases can be useful at times because they help us make quick decisions and create a sense of order. But they can also distort reality and keep us stuck.

There are many biases that show up in coaching conversations: negativity bias, in which we give more weight to what’s wrong than to what’s working; extrapolation, in which we assume one event predicts the whole future; and choice-supportive bias, in which we defend decisions simply because we made them.

The one I want to explore today is the conservatism bias.

Conservatism bias is the tendency to keep believing something because we believed it first. It’s a resistance to new or updated information, even when that information may be more accurate or useful. It’s the mind’s preference for the familiar conclusion, the old identity, the known story.

In simple terms, conservatism bias says: “I already decided what this means, and I don’t want to update the file.”

And the cost can be high. Because what if the belief we’re protecting is no longer true? What if the story we’re loyal to is outdated? What if the bias itself is getting in the way of a happier, more fulfilled life?

The Old Story Still Running the Show

Conservatism bias often shows up in coaching when a client says they want change but continues to defend the old belief system that makes change feel impossible.

For example, a client may come to coaching with the belief, “I'm just not a confident person.” This may have been true at one point. Maybe they were shy as a child. Maybe they were often criticized. Maybe they had experiences that made them doubt themselves. So the belief formed: I’m not confident.

But over time, that client may begin to behave differently. They may start speaking up in meetings. They may set a boundary, have a difficult conversation they used to avoid, or receive positive feedback at work.

Still, when asked to acknowledge these new choices, they might say, “That doesn’t really count,” “I was just lucky,” or “I still felt nervous, so it doesn’t mean I'm confident.”

That is conservatism bias. The client is receiving new evidence, but the old identity still feels more believable.

Another example may come from relationships. A client might believe, “People always let me down.” This belief may have roots in real disappointment. It may stem from past betrayal. The belief may once have been protective. It helped the client stay alert and avoid being blindsided. But now, perhaps they’re in a relationship with someone steady and consistent. This person follows through. They communicate. They try. Yet the client keeps scanning for proof that disappointment is coming. One missed text carries more emotional weight than twenty examples of reliability.

Again, the old belief wins.

This is where conservatism bias can be especially damaging. It prevents people from grasping the full truth of what's happening. The client isn't intentionally lying to themselves. They're simply giving more weight to old information than to new information.

The Power of Rewriting the Story

Challenging conservatism bias can be uncomfortable because it asks us to loosen our grip on familiar conclusions. A person may not want to believe they're becoming more confident because confidence feels unfamiliar. They may not want to trust a healthy relationship because trust feels vulnerable. They may not want to see early signs of progress because hope feels risky.

The goal isn't to force positive thinking. It's not to deny difficulty or pretend everything is better than it is. The goal is to become more curious about what's true and to look for evidence. Begin by asking yourself:

• What information am I ignoring?

• What new information deserves to be included?

• What belief might need to be revised?

• What evidence exists that supports this new belief?

Breakthroughs often begin when a person can say, "That may have been true before, but it may not be the whole truth now." This creates enough space to consider a new response, a new choice, a new identity, or a new possibility. This matters because many people are stuck because their old story or way of seeing themselves or the world has become outdated. They're still organizing their lives around an old conclusion that no longer works.

Challenging conservatism bias means learning to notice when we're defending a belief simply because it's familiar. It means being willing to examine whether our current interpretation is still serving us. Because once a person can rewrite the story, they can improve the strategy. And once they update the strategy, new possibilities and outcomes emerge.

This is the kind of work we do in coaching. We look at the stories and patterns that may be keeping you stuck, and explore what else could be true.

This can be hard to do on your own, especially when you feel discouraged, defensive, or unsure of what to do next. But with support, new insight and change are possible.
