Your Brain Has Bugs
Behavioral economics studies how real humans make decisions—often irrationally. Here are 12 biases affecting you daily.
1. Loss Aversion
What it is: Losses feel about twice as painful as equivalent gains feel good.
Example: Losing $100 hurts more than finding $100 feels good.
Real-world impact: People hold losing investments too long, hoping to break even.
Counter it: Ask "Would I buy this today?" If no, sell.
2. Anchoring
What it is: Over-relying on the first piece of information encountered.
Example: A shirt "marked down" from $100 to $50 feels like a deal—even if it was never worth $100.
Counter it: Research prices independently before shopping.
3. Confirmation Bias
What it is: Seeking information that confirms existing beliefs.
Example: Only reading news that aligns with your political views.
Counter it: Actively seek opposing viewpoints.
4. Sunk Cost Fallacy
What it is: Continuing something because of past investment, not future value.
Example: Finishing a bad movie because you paid for the ticket.
Counter it: Ask "Ignoring what I have spent, is this worth continuing?"
5. Present Bias
What it is: Overvaluing immediate rewards vs. future rewards.
Example: Spending now instead of saving for retirement.
Counter it: Automate savings; make the right choice the default.
6. Availability Heuristic
What it is: Judging probability by how easily examples come to mind.
Example: Fearing plane crashes (memorable) more than car crashes (common).
Counter it: Look up actual statistics before making decisions.
7. Status Quo Bias
What it is: Preferring the current state of affairs.
Example: Staying with a bad phone plan because switching is effortful.
Counter it: Schedule regular reviews of recurring decisions.
8. Herd Mentality
What it is: Following the crowd without independent analysis.
Example: Buying stocks because everyone else is (tulips, meme stocks).
Counter it: Ask "Would this make sense if nobody else were doing it?"
9. Overconfidence
What it is: Overestimating your own abilities and knowledge.
Example: Thinking you can beat the market when most professionals cannot.
Counter it: Track your predictions; reality is humbling.
10. The Endowment Effect
What it is: Valuing things more simply because you own them.
Example: Wanting $1,000 to sell a possession you would not pay $500 to buy.
Counter it: Imagine you do not own it. What would you pay?
11. Choice Overload
What it is: Too many options lead to decision paralysis.
Example: Fewer jam varieties = more purchases (famous study).
Counter it: Limit options; use "good enough" as a criterion.
12. Mental Accounting
What it is: Treating money differently based on source or intended use.
Example: Splurging a $1,000 bonus but pinching pennies on salary.
Counter it: Money is fungible. A dollar is a dollar.
How to Apply This Knowledge
- Recognize when biases might be at play
- Pause before making important decisions
- Use systems (automation, checklists) to override bad intuitions
- Seek outside perspectives from people who think differently
