3 Cognitive Biases Ruining Your Decisions

You think you are rational, but you are not. Your brain is evolved for survival, not for truth. It uses shortcuts called "heuristics" to save energy, but these shortcuts often lead to logical errors known as Cognitive Biases.

Understanding these three biases is the first step to thinking clearly and making smarter financial and life choices.

1. The Sunk Cost Fallacy

This is the tendency to continue doing something just because you've already invested time or money into it. "I've already watched 4 seasons of this boring show, I have to finish it."

The Fix: Ask yourself, "If I started today with zero investment, would I choose this?" If the answer is no, quit immediately.

2. Confirmation Bias

We only look for information that confirms what we already believe. If you think a diet works, you will only read success stories and ignore the failures.

The Fix: Actively search for evidence that proves you wrong. This is how scientists think.

3. Survivorship Bias

We look at successful people (Steve Jobs, Bill Gates) and try to copy them, ignoring the thousands of people who did the exact same things but failed. We focus on the "survivors" and ignore the "graveyard."
