Have you ever played an old Nintendo game and found that blowing on the cartridge seemed to fix it when it went all glitchy? It felt like magic, right? Well, it turns out that our brains are really good at spotting patterns, even when they aren’t there. This skill helps us make sense of the world, like figuring out how to win at Mario Bros. or understanding the consequences of our actions.
Our ancestors relied on recognizing patterns to survive. They needed to know which berries were safe to eat and the best times to plant crops. This ability to find meaning in chaos was crucial for their survival. Even today, our brains are wired to detect patterns, but sometimes they can trick us into seeing things that aren’t real, like faces in shadows or connections between random events.
Our brains don’t like uncertainty, so they often try to make sense of things by sticking to what they already believe. This is called confirmation bias. It means we tend to notice information that supports our views and ignore anything that contradicts them. Another mistake we make is the post hoc fallacy, where we assume one event caused another just because it happened afterward. We might also think random events have special meanings, which is another way our brains can mislead us.
Remember blowing on those Nintendo cartridges? It didn’t actually fix anything; it was just a trick our brains played on us. We saw others doing it and thought it worked, so we did it too. This is an example of how we can see patterns where there are none. It’s like a thought virus that spreads, even without evidence to back it up.
Science helps us avoid these mental traps. Instead of starting with a conclusion and ignoring conflicting evidence, science begins with a question and tries to prove it wrong. This method is relatively new, and in the past, even smart people had misconceptions about the world. By challenging our ideas, science helps us understand the complex world around us.
The world is full of patterns, but not all of them are real. While patterns can guide us, they can also lead us astray. That’s why it’s important to keep questioning our beliefs and stay curious. If we don’t, we might end up lost in a world of misconceptions.

Explore the world around you and identify patterns in nature, art, or everyday objects. Take photos or draw sketches of these patterns and present them to the class. Discuss how these patterns might have been formed and what they tell us about the environment or culture.
Conduct a simple experiment to understand confirmation bias. Create a survey with a question that might have different answers based on personal beliefs. Analyze the results to see if people tend to choose answers that align with their existing beliefs. Discuss how this bias can affect decision-making.
In groups, create a short skit that demonstrates the post hoc fallacy. Choose a scenario where one event is mistakenly believed to cause another. Perform your skit for the class and explain why the conclusion was incorrect. Discuss how to avoid this fallacy in real life.
Research the myth of blowing on Nintendo cartridges. Find out why people believed it worked and what the actual solution to the problem was. Present your findings to the class and discuss how this myth is an example of seeing patterns where none exist.
Choose a simple question or hypothesis to test using the scientific method. Design an experiment, collect data, and analyze the results. Share your process and findings with the class, highlighting how the scientific method helps us avoid mental traps and misconceptions.
Sure! Here’s a sanitized version of the transcript:

If you played old-school Nintendo, then you might remember when your game went all crazy, and you blew on the cartridge, and it seemed to work. Beating a game like Mario Bros. is all about knowing the patterns, and our brains are excellent at that. They help us pick out meaning from chaos, allowing us to sense danger and see the consequences of our actions. For our ancestors, this ability could mean the difference between life and death—knowing which berries to eat or when to plant crops.
While our brains have evolved over time, they may not have kept pace with the rapidly changing world around us. We still operate with much of the same hardware we had thousands of years ago, which can lead to misunderstandings. Our brains are so adept at recognizing patterns that sometimes they see them even when they aren’t there. For example, we can perceive faces in shadows or find meaning in random events.
This tendency to be mistaken might stem from a flaw in our wiring. Our brains dislike uncertainty and strive to be right about our perceptions. This leads us to filter information in ways that support our conclusions while ignoring evidence that contradicts them. This is known as confirmation bias. We may also fall victim to the post hoc fallacy, assuming that one event caused another simply because it occurred afterward. Additionally, we might insist that random events have significance, which is another cognitive error.
Reflecting on the Nintendo experience, I realized that blowing on the cartridges didn’t actually help; it was just a trick our brains played on us. Interestingly, this behavior was widespread, spreading like a thought virus in a pre-digital world. In some cultures, there are still common beliefs that persist despite a lack of evidence, demonstrating the common belief fallacy.
When I saw my friends blowing on their Nintendo games, I did the same, thinking we were improving the connection. In reality, it was just a way to give ourselves a reason to try again. This illustrates how we can perceive patterns where there is only randomness.
Science was developed as a method to combat our tendency to assume that our perceptions are accurate. Rather than starting with a conclusion and filtering out conflicting data, science begins with an explanation and seeks to prove it wrong. This approach is relatively recent; not long ago, many intelligent people held misconceptions about the natural world.
The world is complex and doesn’t always make sense. While patterns can help us navigate through randomness, they can also lead us astray. Science requires a commitment to challenging our own ideas, using it as a tool to ensure our understanding is sound. If we don’t regularly question our beliefs, we may find ourselves lost.
Stay curious!
