Why "Everyone We Talk To Loves It" Is the Most Dangerous Sentence in Startups

I've heard this sentence more often than almost any other in early-stage founder conversations — and it almost always precedes a difficult discovery. Not because early enthusiasm is wrong, but because the cognitive state 'everyone loves it' creates is nearly impossible to exit voluntarily. Once a founder has heard enough enthusiasm, disconfirming data gets reframed as an implementation issue, a targeting problem, or a one-off exception. The sentence is also a selection artefact: you're talking to people who said yes to a meeting. The people who find your product uncompelling never get to the calendar invite. Your dataset is missing its most valuable respondents before a single question is asked.
