From the Penalty Spot to Your Portfolio
What penalty kicks, emergency landings, and sports bets have in common: we all think we'd be fine.
The final whistle blows, and your heart sinks a little as you realize the game will be decided by penalty kicks. You’ve just watched two hours of a back-and-forth match come down to a handful of well-placed shots.
The kicker spots the ball, twelve yards from a professional goalkeeper who has spent their entire adult life doing exactly one job. Last week, we talked about where a kicker should aim if they only had one shot and wanted to maximize their odds of scoring.
Today’s question is simpler: do you think you’d score in that situation?
Of course, we could have flipped the question and asked about the other side of the kick. If we put you in the net as the goalkeeper, could you stop a penalty kick against a professional striker? The numbers come back similarly bold on both sides. A lot of people, watching from their couches, are convinced they’d be fine out there.
A recent YouGov America survey found that roughly 1 in 4 Americans believe they could score a penalty kick against a professional goalkeeper. It stood out because penalty kicks are uniquely high-pressure moments in sports with intense individual scrutiny and a high-stakes outcome. And yet a lot of people don’t seem fazed by any of that.
We’ll see how our own reader poll stacks up against that. For now, here are the results of that survey:
But I’m different…
I told myself I wouldn’t write another soccer story, but it was hard to pass on these findings. That was a representative survey of U.S. adults. We’re talking about people with no special training in the sport and who have likely never done anything in front of 80,000 people. And still, they’re sure they could do it.
Of course, this isn’t really a story about soccer. It’s a story about economics.
This hubris can be found in a variety of scenarios. Nearly half of all men say that in an emergency, they could land a commercial airplane with an air traffic controller talking them through it on the radio. A notable share of people say they could win a fight against a gorilla. And a majority of people say they could perform CPR on an adult whose heart has stopped, even though only one in six actually know the recommended technique for bystander CPR is chest compressions alone, no rescue breaths.
Notice how wide the contexts are? We’ve got airplane cockpits, wildlife enclosures, cardiac emergencies, and penalty kicks. The stakes are wildly different, yet a suspicious number of people believe they’d clear a hard, objective bar even without knowing what the bar actually requires.
There’s a name for this in behavioral economics: overconfidence bias. It’s the tendency to overestimate our own abilities, our odds of success, and our control over outcomes. It’s one of the most replicated findings in all of behavioral economics, tested across education, dating, investing, health, parenting, you name it. It holds up nearly everywhere researchers look.
Okay, so what?
These are fun surveys, but they’re also all things most of us will never actually be tested on. You’re probably never taking a World Cup penalty kick or landing a commercial plane, and you’re (hopefully) not fighting a gorilla. So why should any of this matter to you?
Stop looking at the examples and start looking at the behavior underneath them. The specific scenario isn’t the point. It’s the belief that you could handle something hard, with no real basis for thinking so. That reflex doesn’t stay contained to hypothetical emergencies you’ll never face. It shows up in decisions you’re actually making, with actual money, right now.
Take investors. Overconfident traders are convinced their read on a stock is sharper than everyone else’s, so they trade more often than cautious ones do. That seems reasonable enough since people who are right more often should act more often. Except the data runs the other way. Studies find that the more actively individual investors trade, the worse their returns tend to be.
Or look at the explosion of sports betting and prediction markets, especially among young men. Over half of American men ages 18 to 49 now have an active sportsbook account, and bettors overwhelmingly say they believe they can make money doing it. And yet only 3 in 10 say they’ve actually come out ahead. The participants in these markets skew younger, more educated, and male. It’s the same group that tends to be more overconfident in plenty of other contexts, too.
There’s nothing inherently wrong with believing in yourself. The issue is that we’re misjudging ourselves in ways that can actually cost us financially (or physically in a fight against a gorilla). These findings aren’t just random noise with some people guessing high and some guessing low until it all washes out. It’s a systematic bias, and one that entire industries are built to profit from.
Final Thoughts
If you didn’t already know it, you now have a name for the flicker of confidence you felt when you read the opening of this article. The real question was never really “would you score?” It’s why you think you would.
That flicker is the same one sitting inside the investor placing one more trade, and the bettor certain this is the pick that finally pays off. It’s not stupidity or even arrogance. It’s something closer to a factory setting in the human mind, running in the background while you’re watching the penalty-kick shootout or logging into your brokerage account.
We could write an entire separate article on prediction markets alone given how fast they’re growing, but that’s a story of its own that we’ll come back to another day. For now, the takeaway is simpler than that. The next time you feel completely sure about something, it might be worth pausing for half a second to ask what that certainty could cost you.

That "41% of men under 30..." stat made me laugh out loud! Also, I love your description of a cognitive bias like overconfidence as a "factory setting in the human mind." Thanks, Jadrian! This one led to a lot of discussion at Econiful :)
Sure. In psychology, you are precisely describing the Dunning-Krueger Effect (DKE). As in this article, there is usually no hesitation in saying that the effect is "universal". Since the original 1999 paper, there has been a lot of further investigation. DKE is not an overconfidence problem -- to a great extent it is a metacognition problem -- the person who does not have a skill is not surprisingly bad at assessing how difficult the skill is and whether they are capable of doing it. The most effective way of mitigating the mis-assessment of skill level is to teach the person the skill. There is also a cultural aspect: people in Far Eastern cultures (Japan, China) exhibit DKE at a lower level. Here is what I think (disclaimer: I am an Economist, not a Psychologist, so my assessment skill may be poor) is a pretty good overview:
