Mission Brief 010 – Spotting Cognitive Biases

Don’t Believe Everything You Think

We like to think we’re rational, but our brains often rely on shortcuts — called cognitive biases — that can distort reality. These biases evolved as survival mechanisms, but in today’s complex world, they can mislead us.

• Confirmation bias makes us seek only information that supports what we already believe.
• Anchoring bias makes us cling to the first number or idea we hear.
• Availability bias makes us overestimate risks or likelihoods based on vivid, recent examples.

By learning to spot these patterns, you sharpen your thinking and make stronger decisions. Awareness is the first step.

Fun Factoid

Research shows people are more likely to believe an incorrect statement if it’s repeated often — a quirk of confirmation bias known as the illusory truth effect

Why It Matters

Unchecked biases can lead to poor decisions, reinforce stereotypes, and close off opportunities for growth. Spotting bias helps us make choices based on reality, not comfort. This self-awareness is a cornerstone of true critical thinking..

Field Notes

I traveled to France about 10 years ago during my first trip to Europe, I kept hearing the stereotype that French people were rude. Before going, I did some reading and learned that in France, it’s customary to greet people with “Bonjour” before making a request, something that some tourists skip. I made a point of doing this everywhere I went. To my surprise, all the people I met in Paris and Normandy were warm, helpful, and kind.

It struck me how easy it would have been to fall into confirmation bias — noticing only moments that confirmed the stereotype while ignoring the many times people were pleasant. By approaching the situation with awareness and a small adjustment in behavior, I was able to see past the bias and experience the culture more authentically.

Bias at play:

• Availability bias: The stereotype was vivid and repeated, so it felt true.
• Confirmation bias: If I hadn’t read about the greeting custom, I might’ve interpreted neutral behavior as rude, reinforcing the stereotype.

This experience reminded me that expectations shape perception—and that challenging them opens the door to more accurate, empathetic understanding.

Actionable Item

Pick one bias (confirmation, anchoring, availability). Watch for it in your own thinking today.

“The ultimate goal of critical thinking is to be able to make reasoned judgments, not simply to be right.” — Dr. Peter Facione

Reflection

What’s a decision you’ve made that might have been influenced by a cognitive bias? How might you have approached it differently?
