Most people think they’re above average in intelligence, relationship status and professional achievement. Social scientists call this “illusory superiority.” My business partner Scott Puritz, has found the one area[1] where even above-average people, objectively smart, rich, successful professionals, seem to wave the white flag and admit to not understanding — money and investing.

“One of the most shocking things is the low-level financial literacy throughout our culture,” Puritz told the Washington Post. “It’s independent of education. Doctors, MBAs, corporate executives are incredibly competent in everything they do. But when it comes to investing, you run into this cauldron of mostly negative emotions, embarrassment, frustration, guilt. It leads to paralysis.”

Sound like you? If so, don’t worry. You’re not alone. Two-thirds of Americans can’t pass a five-question financial literacy test, according to FINRA[2], the industry-run regulator that oversees stockbrokers.

And that’s because the fundamentals of finance are boring, and aggressively so. To understand it you need to grasp the interplay of money and time, and that’s just hard for humans to do. Both money and time are abstractions. Figuring out how they relate is a real challenge.

As Scott explains, the outcome is that even people with advanced degrees and professional success can fail at building a nest egg[3]. And they fail, interestingly, in two distinct ways.

Street education

One group tells themselves that they don’t understand money and delegates the responsibility to a professional. They get “a money guy” who seems to be capable of investing their savings and just forget about it for a few decades.

A second group does get a bit more educated, but it’s largely a street education. They open a trading account, plunk down a few thousand bucks and start hunting for stock tips.

Maybe the neophyte trader makes a bit of money or maybe he loses a bit, but he usually gets bit by the market bug and stays with it, buying and selling on his own with no help at all.

Both approaches are extremely risky, for different reasons.

The first group, by abdicating responsibility for their own money, can fall victim to scams. It happens all the time. Often, though, they get reasonably good investment help but pay tremendously high fees for what turns out to be average long-term returns.

The fees, of course, absolutely devour those returns. The typical investor pays 1% for investment advice and another 1% in fees for mutual funds bought in their name.

The result: One-third and up to one-half of investor gains is absorbed by fees. The “money guys” take zero risk (it’s not their money, it’s yours) but nevertheless get a huge reward.

The second group, the emboldened traders, also can fall victim to scams. Penny stocks, illiquid investments, and highly leveraged strategies are just a few examples.

Mostly, though, amateur traders fall victim to the...
