cognitive bias

  • Optimism Bias

    You’re going to be fine. That’s what you tell yourself, you’re less likely to get lung cancer even though you smoke. You’re less likely to have a car accident even though you text while driving. You’re less likely to fail even though you haven’t prepared, you’re going to be the exception to the rule. That’s…

  • The Pygmalion Effect

    You perform at the level expected of you. Not at the level you’re capable of, not at the level you want to reach, at the level others expect from you, and more importantly, at the level you expect from yourself. That’s the Pygmalion Effect in action, and it’s either working for you or against you…

  • The False Consensus

    Nobody likes being wrong. That’s not a character flaw. It’s human, but some people take it further. They don’t just dislike being wrong, they can’t tolerate it. They’ll move heaven and earth to avoid being proven wrong, to reframe the evidence, to find anyone who agrees with them. Then they make a critical error, they…

  • Survivor Bias

    You only see the winners. That’s the problem. You see Bill Gates, Mark Zuckerberg, Steve Jobs. All dropped out of university, all became billionaires. So you conclude that dropping out leads to success. You don’t see the thousands who dropped out and failed. That’s survivor bias. You’re only seeing the survivors, only seeing the winners,…

  • Social Proof Tendency

    You’re doing what everyone else is doing. Even when it’s wrong. Perhaps you look around before you act. Maybe you check what others think before you speak. You follow the crowd because the crowd must know something you don’t. That’s social proof tendency, and it’s running your life more than you realise. It’s not always…

  • Bottlenecks

    You can get stuck because what’s going on inside your head doesn’t match what’s actually happening in the real world. Let me show you what I mean. You believe you’re terrible at your job. The evidence? Your boss gave you some feedback that you didn’t really think was fair. Meanwhile, in reality, you’ve been promoted…

  • Doubt Avoidance Bias

    Your brain wants you to make decisions fast. Not good decisions. Not thoughtful decisions. Just fast ones. This made perfect sense when you were running from predators on the savannah. It makes considerably less sense when you’re choosing a career, ending a relationship, or deciding whether to send that angry email. This is called Doubt…

  • Self Enhancing Transmission Bias

    Everyone’s a winner on LinkedIn. Every post is about crushing goals, smashing targets, and achieving incredible success. You’d think nobody ever failed at anything. You’d think every business decision was a stroke of genius, every investment returned 300%, and every career move was perfectly timed. You’d think failure didn’t exist, that the road to success…
