Past Experience Can Lead Us Astray

"The illusion that we understand the past fosters overconfidence in our ability to predict the future."

-Daniel Kahneman

Imagine I organize a coin-flipping contest. In this contest, 1,000 people square off in a March Madness-like bracket, with 500 first-round matches. The winner of each match is the one who flips the most heads in a row. After about 10 rounds we find ourselves watching the championship between the best two head-flippers.


We know this is a competition that doesn't rely on skill. Yet, the final two out of 1,000 will feel a sense of control over the outcome. We know, because we are outside of the situation, that no matter what happens there has to be two final people, and then a winner. That's just math.


A funny thing happens when you are the one experiencing the random math. Imagine you did "win" two matches, then three, and four, and so on. Our experience is that we flipped seven heads in a row, several times.


The outcome of our experience had to happen to someone, but the fact that it was us is random. Though we feel like we have some control, we're missing the bigger point.


Let me tell you something you already know; this phenomenon doesn't just happen with flipping coins.



Recognizing Patterns


We are very good at spotting patterns. Random things happen all the time and we're been wired to think there's meaning behind it. We might call these coincidences.


The ability to spot patterns may have helped out ancestors; after all, if you noticed that it only rains when there are clouds in the sky it gave you an advantage over those who didn't know. It's easier for us to believe there's a pattern or a reason behind something than to have to admit to ourselves that probability and randomness are all around us.


We spot patterns in stock prices. We see patterns in politics. We think there are patterns in others' behaviors. Some even think patterns exist between which socks they wear and the outcome of sporting events.



Pattern Recognition is Easy


It's easy for us to recognize patterns. But raining only when there are clouds isn't the same thing as it raining any time there are clouds.

True, there are patterns that we detect that make sense. However, there are more that are mere random, have no base in reality and aren't able to predict the future.



Small Sample Sizes


It's quite intuitive to think experience is the best teacher. Every job interview I've ever had featured a discussion about my experience. They wanted to know if I had enough experience. They wanted to know if I had the right kind of experience.


To understand the problem with experience and our view of the world I have to use a little bit of jargon - I apologize ahead of time. If we want to make sure something is a fact and not just an outlier we need to know about the whole universe. Since that's impossible, we have to get what statisticians call a sample. If our sample is not biased, meaning the sample represents the whole universe, then our sample can give us good information - if it's sufficiently large. The smaller our sample is, the more likely it is that our observations are extreme.


Jaron over...Let me try again with an example and plain English.


I'm going to use an example of a common belief, that the rich are bad people. You may hold this belief or one like it - the only way to get rich is to take advantage of people, rich people only care about money, rich people are greedy, and so on. For our purposes, let's assume a person named Kim believes rich people are bad.


It's completely possible that Kim's experience is accurate. That is, every time Kim met someone "rich," that person was a real jerk.



If every person who was "rich" turned out to be a bad person, it's very easy to jump to the conclusion that every rich person is bad. That's what Kim observed.


But we don't observe everything. We only see a sample and our observations are small. The truth is that there are many bad people, and there are many rich people, but there are fewer who are both bad and rich.



Confirmation Bias


It gets even trickier. We can assume Kim's whole experience with rich people ended with each rich person being a bad person, but that wouldn't be the whole truth. This is because of a bias we all have called confirmation bias. I should point out that most of the time we have no idea that we're doing this. Once we have a belief our ego wants us to be right. We will now notice things that confirm our beliefs. When we come across something that doesn't fit with our existing beliefs we dismiss it as being a fluke, find a reason to not believe it, or we don't even notice it.


You've no doubt come across this if you watch the news. CNN fans are being fed what they want to hear and Fox News fans are being fed what they want to hear. For our friend Kim, every time there was a news story about a rich greedy person ripping someone off it was recognized and remembered. Whenever there was a story about a rich person who started a foundation to help underprivileged kids get educated or to bring necessary medical aid to those in need, it doesn't get recognized.



Kids Are Highly Susceptible


If real-world experiences and mislead us as adults, then children have no chance. Kids' brains won't fully develop for a couple more decades. As they go about their life, they try to make sense of the world through careful observation. They, pick up on patterns they think they see, and they internalize them as beliefs.



Money Script Development


For example, if the only time they hear money being talked about is when mom and dad are fighting, they'll create a belief around that. If the only time they hear about "rich" people is when their parents talk about those greedy "rich" neighbors, they'll create a belief around that. Remember, children don't know about small sample sizes, confirmation bias, outliers, or random events. Heck, most of us don't.


When these beliefs that we develop are about money and how money works, they are called money scripts. Money scripts are beliefs about money that we carry with us into adulthood, and they drive our financial behaviors. Think about how our old friend Kim might behave around money. Having a belief that rich people are bad might make it hard for Kim to accept raises or promotions at work, or save and build up a nest egg. Kim is a good person, and to him, having money is the same as being a bad person. These two beliefs aren't compatible, so Kim chooses to underearn and undersave. Someone else holding onto these same beliefs may save and earn money, but will be afraid to tell anyone for fear of being treated differently. Money scripts can limit us if we don't explore them further.



I used a common example throughout this article about rich people being bad. This is just one of many beliefs that people have picked up about money.


Challenge: what beliefs do you have about money and money's role in the world that might be negatively impacting you? Is that belief challengeable? Do these beliefs cause trouble for you (after reflecting on it) as you try to make smart decisions with your money?


What is one small thing you can do to check the validity of your beliefs?


You only have one life. Live intentionally.
