THE FALSE CONSENSUS EFFECT

Summary from the TLDR Founders newsletter

Marketers often assume customers think like they do – and pay for it. The “False Consensus Effect” explains why: we mistake our own tastes for the norm. Netflix proved the power of testing assumptions when it dropped House of Cards all at once and watched viewers binge six episodes in days. Amazon built its empire on A/B tests, not opinions. Sometimes you're not your customer, so stop building for yourself.
