In This Episode:
Once you know something well, it’s almost impossible to remember what it was like not to know it. This episode uses the famous “tapper and listener” experiment to explain the curse of knowledge, how it quietly wrecks communication, teaching, delegation, decision making, and product design, and gives concrete ways to catch it before it costs you.
What You’ll Learn
- The tapper and listener experiment: why listeners correctly guessed a tapped-out song only 3 times out of 120, even though tappers expected a 50% success rate
- How the curse of knowledge shows up in jargon, abbreviations, and assumed background knowledge that leaves people lost
- Why it quietly wrecks delegation: you have the full picture in your head, but the person you’re delegating to doesn’t
- How it affects teaching, coaching, and feedback by making you skip the fundamentals that once mattered to you
- Why products and websites that feel intuitive to their designers can be completely unusable to everyone else
- Practical fixes: the “grandma test,” repeat-backs, over-communicating, and building psychological safety so people will actually say “I don’t understand”
