The Independent Investor Type Explained - Behavioral Finance Chapter 10
Chapter 10 of Behavioral Finance and Investor Types by Michael M. Pompian introduces the Independent. If the Follower from the last chapter was the passenger, the Independent is the person who insists on driving. And reading the map. And ignoring the GPS because they “know a shortcut.”
Independents are the do-it-yourself investors. They have their own ideas about the market, they do their own research, and they are not afraid to go against the crowd. Pompian describes them as analytical, critical thinkers who act on logic and gut instinct. They are willing to take risks and they make decisions fast. On paper, this sounds great. In practice, it can blow up.
The Good Side of Being Independent
Here’s the thing. Being an Independent actually has real advantages. These people think for themselves. They don’t follow the herd. While everyone else panic-sells or buys into hype, the Independent can stay contrarian and that can be very profitable.
They tend to understand financial language. They are not scared of reading into fees, costs, and the boring details of investments. They can find low-cost service providers because they actually bother to compare. They are thinkers and doers, not dreamers and followers.
Pompian says Independents have above-average risk tolerance and a realistic understanding that risky assets can go down. They get it. At least in theory.
But Here’s the Problem
The downside is that Independents can be their own worst enemy. They sometimes act too fast without doing enough homework. Reading one article in a business magazine and calling it “research” is not the same as actually understanding an investment. Half-ready, full-on pursuit of profits, as Pompian puts it.
And when their picks go bad? They don’t like to admit they were wrong. Sound familiar?
Independents also have a habit of letting the “tax tail wag the investment dog.” They get so focused on tax efficiency that they forget to pick a good investment strategy in the first place.
The Two Big Biases: Confirmation and Availability
The dominant biases for Independents are both cognitive, meaning they come from faulty thinking patterns rather than emotions.
Confirmation Bias
This one is classic. You make a decision, and then you only pay attention to information that tells you it was a good decision. Everything that says you were wrong? Ignored.
Pompian gives a great example. Jack, a 43-year-old guy, was heavy into real estate in the 2000s. He saw condos and strip malls popping up everywhere. Prices kept going up. Banks kept lending. His confirmation bias got reinforced year after year. He put most of his portfolio into real estate. He could have noticed that bad loans were piling up and new inventory was outstripping demand. But he told himself those problems were only in certain cities. He was in New York, LA, Miami. Those would never lose value, right?
Then the market crashed and his portfolio went with it. If he had been willing to look at information that contradicted his belief, he might have diversified and protected himself.
Availability Bias
This one is about how we judge information based on how easy it is to remember or access. If something is fresh in your mind, it feels more true and more important.
Pompian breaks availability bias into four flavors:
Retrievability. The stuff you can recall easily feels more credible. Ask someone what the best mutual fund company is and they will name Fidelity or Schwab because those companies advertise a lot. Doesn’t mean they are actually the best performers.
Categorization. We put things in mental boxes. Ask Americans where the best investment opportunities are and most say the United States. Meanwhile, over 50% of global equity market cap is outside the US. That’s home country bias and it costs people money.
Narrow range of experience. Bob works in tech. Bob thinks tech is the best industry to invest in. Bob doesn’t know anyone in other industries. Bob has a very lopsided portfolio.
Resonance. You invest in things that match your personality. A bargain hunter goes all-in on value stocks and misses growth opportunities. You see the world through your own lens and forget there are other lenses.
Three More Biases Worth Knowing
Beyond the big two, Pompian identifies three additional biases that show up regularly in Independents.
Self-attribution bias. When your picks go up, it was your brilliant analysis. When they go down, it was bad luck or the market being unfair. This inflates your confidence and leads to excessive trading. A little knowledge is a dangerous thing, Pompian warns.
Conservatism bias. Clinging to old information when new data says you should change course. James gets bad earnings news about a company but sticks to the old positive estimate because that’s what he based his original decision on. The stock tanks. James loses money because he refused to update his thinking.
Representativeness bias. Forcing new information into familiar patterns. This includes base-rate neglect, where you assume a hot IPO is a great long-term investment because it looks like other successful companies, when statistically most IPOs underperform over time. It also includes sample-size neglect, where three good stock picks from a broker make him a genius, even though his track record over a longer period is mediocre.
How to Help an Independent
Pompian’s advice for working with Independents is straightforward. They can be tough to advise because they are stubborn. But they are usually grounded enough to listen if you respect their independence and back up your recommendations with data.
Education is the key. Since their biases are mostly cognitive (thinking errors, not emotional ones), you can actually fix them with information. Regular discussions about portfolio diversification and the benefits of sticking to a long-term plan work well. The trick is not to point out their specific failures but to educate consistently so they absorb the concepts over time.
For those of us who see ourselves in this description, the takeaway is simple. Do your research, but be honest about whether you are really researching or just looking for reasons to believe what you already believe. Challenge your own assumptions. Look at the data that makes you uncomfortable. That’s where the real edge is.
