Investing Psychology Chapter 8: Debunking the Money Myths
We’re nearing the end of Tim Richards’ “Investing Psychology.” In Chapter 8, he tackles the myths that keep us trapped in bad financial habits.
Here’s a weird fact to start: if you want a favorable decision from a judge, make sure your hearing is right after lunch. When people get hungry or tired, they suffer from ego depletion. Their self-control vanishes, and they fall back on lazy biases. Don’t make big financial decisions on an empty stomach.
Myth: Money Makes You Happy
It doesn’t. Or at least, not the way you think. We suffer from the focusing illusion. When we think about having more money, we only think about the fun stuff (vacations, new cars). We ignore the negatives (longer hours, more stress).
Money is a means to an end, not the end itself. If you’re investing just to see a bigger number on a screen, you’re missing the point.
Myth: Everyone Can Be a Good Investor
Self-control is the “secret sauce” of investing. If you can’t resist buying things on impulse or if you like to gamble, you will probably be a terrible investor.
Richards mentions fruit sellers in India who would rather borrow money at high interest rates than give up two cups of tea a day to save up capital. We all have “temptation goods.” If you can’t control yours, let someone else manage your money.
Myth: Debt Doesn’t Matter
Warren Buffett compared debt to driving a car with a dagger mounted on the steering wheel. You’ll drive very carefully, but one tiny bump will be fatal.
Never borrow money to buy stocks. It turns you into a “forced seller.” When the market crashes, the bank will force you to sell your stocks at the bottom to pay back the loan. It’s the easiest way to turn a temporary market dip into a permanent financial disaster.
Myth: The 7% Return
Everyone tells you to expect 7% returns from the stock market. Richards says this is overoptimistic.
Once you account for inflation and fees, the real “equity premium” is probably closer to 3.5%. If you’re planning your retirement based on a “guaranteed” 7%, you’re probably not saving enough.
The Dunning-Kruger Effect
Some people are “too stupid to know they’re stupid.” This is the Dunning-Kruger effect.
In the market, these are the people who are 60% overconfident in their abilities. They don’t have a track record, but they talk like they’ve solved the market. If someone sounds 100% certain about a stock pick, they’re probably sitting in the “stupid corner.”
7 Key Takeaways from Chapter 8
- Don’t confuse money with happiness. Invest for security and time, not just numbers.
- Self-control is everything. If you don’t have it, HAND OFF the keys.
- Learn basic math. You can’t analyze a company if you don’t understand interest.
- Markets crash often. It’s a feature, not a bug. Be ready.
- Debt is a dagger. Avoid it at all costs.
- Adjust for inflation. 5% gains mean nothing if inflation is 6%.
- Track your results. Your brain is hard-wired to ignore your own failures.
In the final chapter, we’ll wrap everything up and look at the “big picture” of the investment industry.
