Essentials / Cognitive Biases / Proportionality Bias

Big Events Need Big Causes — Right? (Wrong.)

🔥 Hook

A famous celebrity dies. Within hours, conspiracy theories explode online. "There's no way it was just an accident." "Someone that powerful doesn't just die from something random." "There has to be more to the story."

Why? Because a big, important person dying from something small and ordinary feels wrong. It feels incomplete. Your brain screams: something this huge MUST have an equally huge explanation.

But sometimes a massive event really does have a small, random cause. And your brain's refusal to accept that is called proportionality bias.

🧠 What's Actually Happening?

Proportionality bias is your brain's insistence that big effects must have big causes. Important events need important explanations. Huge consequences require huge intentions.

It works the other way too. Small causes must produce small effects. A tiny mistake couldn't possibly lead to a catastrophe. One person couldn't change the world. One decision couldn't ruin everything.

Your brain wants the world to be proportional. It wants the size of the cause to match the size of the effect. When they don't match, your brain rejects reality and starts looking for a "real" explanation — usually a conspiracy, a hidden plan, or a secret powerful force.

This is one of the biggest engines driving conspiracy theories. JFK can't have been killed by one random guy. Princess Diana can't have died in a normal car crash. A global pandemic can't have started from one animal at one market. These events are too big for causes that small. So people invent bigger causes: secret organizations, government plots, deliberate plans.

The truth is, the world isn't proportional. Small things cause big events all the time. And big efforts sometimes produce nothing. That's reality. It's just not satisfying.

Celebrity drama. A famous couple breaks up. "There MUST be cheating or a scandal." Sometimes people just grow apart. But that explanation feels too small for people that famous, so fans demand a bigger story.

Viral moments. A random person's video gets 50 million views. "They must have connections." "It's definitely paid promotion." Sometimes the algorithm just picked it up. A small cause (posting at the right moment) produced a massive effect (going mega-viral). No conspiracy needed.

School rumors. A popular student suddenly switches schools. "Something huge must have happened." Maybe their parent got a new job. But a boring explanation for a surprising event doesn't feel right, so gossip fills the gap.

Gaming. "There's no way that player is legit. They must be hacking." Sometimes someone is just having a great game. An extraordinary performance (big effect) from regular skill plus luck (small cause) feels impossible, so you assume cheating.

World events. "One bat can't cause a global pandemic." "One person can't crash the economy." Actually, cascading systems mean that yes, one small trigger can cause enormous chain reactions. Your brain just doesn't want to believe it.

🔍 How to Spot It

You're experiencing proportionality bias when:

Ask yourself: Am I rejecting this explanation because it doesn't fit the evidence, or because it doesn't feel big enough?

💬 What You Can Do

Accept that the world is disproportionate. Small causes create big effects. Big efforts sometimes produce nothing. This isn't a flaw in reality — it's how complex systems actually work. A single spark can start a forest fire. That's not suspicious. That's physics.

Separate emotional satisfaction from evidence. A "big" explanation might feel more satisfying, but feelings aren't evidence. The true explanation is the one with the most evidence, not the one that feels the most dramatic.

Learn about cascading systems. Once you understand how chain reactions work — in nature, in social networks, in economies — small causes producing big effects stops feeling impossible and starts feeling normal.

Check your conspiracy radar. When you catch yourself thinking "there must be more to it," ask: is there actual evidence of "more"? Or does it just feel like there should be?

Remember: boring is usually true. The boring explanation is right more often than the exciting one. That's not fun. But it's accurate.

🎯 Your Challenge

Find a big event from this week — in the news, at school, online. Look at the explanations people are giving. Is anyone insisting the real cause must be something bigger, more dramatic, or more intentional? Now look at the simplest explanation. Does the evidence actually support the complex version, or does the simple version just feel too small?

Write down both explanations and the evidence for each. Let the evidence decide, not the feeling.
