Repetition Provides The Proof

One of the most persistent problems with identity change is that most people try to argue themselves into a new self-concept instead of consistently accumulating evidence that actively changes their neurobiological systems.

Changing our neurobiology takes time because the brain rewires itself through repetition. New neural pathways are created and strengthened not through insight alone, but through repeated experience. 

Change occurs through learning new skills, experiencing new understanding, and doing things differently. Lasting change requires repeated embodied experience not the mental gymnastics upon which most arguments thrive. 

Most of us think we must achieve a change of epic proportion in order for the change to be of benefit. But it is actually the small, repetitive, doable changesthat lead to successful neural rewiring. 

Our internal arguments are usually predicated on need. We think:

“I need to believe I’m confident. 

“I need to stop seeing myself as broken.”

“I need a better story.”

Identity rarely changes based upon declaration alone. 

It changes through accumulated lived evidence.

This is where small experiments are most effective. 

Instead of asking: 

“What do I need to believe?”


Ask yourself:

“What tiny experiment could produce evidence that my current story is incomplete. 


Identities are not replaced in one dramatic moment.

They evolve through repeated encounters with contradictory evidence.


For example, my client Kyle feels awkward around strangers. He’s done affirmations such as “I am confident. I am magnetic. People love me,” in hopes of changing his story. Predictably, none of these affirmations has worked. He still experiences himself as a socially awkward person. While affirmations are repetitious, they fail to create an embodied experience that is necessary for making lasting change. 

Kyle agreed to co-design a tiny experiment with me and test it out during the following week between our sessions. He agreed to ask one stranger a simple question each day for a week. 

Much to his surprise, everyone answered his question. He asked what time it was, he asked for directions, he asked a waiter to recommend his favorite dish at the restaurant. 

The goal wasn’t an immediate and total transformation of his personality. Instead, the goal was to gather data. He gathered seven days of data. In fact, before the end of the week, he actually questioned two strangers a day rather than just one. 

His lived, embodied experience is slowly starting to counteract his narrative that he’s awkward and doesn’t feel comfortable talking to strangers. Of course, one week of experimenting is not going to create lasting change. But it is planting a seed of curiosity in Kyle’s mind. What if talking to strangers is not as hard as I have always told myself it is? 

His experiment allowed Kyle to notice: 

“Some experiments go well.”

“People responded more warmly than I expected.”

“Maybe awkward isn’t my identity. Maybe it’s a state I enter when I’m nervous.”

Based upon his week of experiments, Kyle had an insight: “I learned my story wasn’t objectively true.” Equally important, he had embodied evidence. “I experienced myself differently.” 

Although he still felt awkward, he was intent on gathering data rather than focusing on his own discomfort. His lived experience changed and I imagine this also positively influenced his results. 

Over time, repeated experiments don’t just change behavior.

They change identity. 

Because eventually the nervous system begins to accept a new possibility:

Maybe the old story was never the whole story. 

Think of a story that is bothering you. What is one tiny experiment you can do that would allow you to collect data about your situation?
