FAQ: Mastering Your Financial Mindset

How can I tell if I’m currently being influenced by a bias?

If you feel a strong emotional urge, either fear or greed, it’s a red flag. Rational decisions usually feel boring and calculated, whereas biased decisions often feel “urgent” or “exciting.”

Is it possible to completely eliminate these biases?

No. Biases are hard-wired into our biology. The goal isn’t to delete them, but to build guardrails like automation and rules that prevent those biases from dictating your actual bank balance.

Does being highly intelligent protect me from financial bias?

Surprisingly, no. Studies show that highly intelligent people are often better at “rationalizing” their biases, making them even more dangerous. System-based rules are more effective than raw IQ.

Why is recency bias so dangerous for long-term investors?

It makes you believe that what happened in the last six months will continue forever. This leads people to buy high after a bull run and sell low during a temporary market correction.
