ValidationProven Pattern

True validation requires risking rejection—diluted validation avoids the moment someone must commit or say no

Most founders don't actually skip validation—they do a safe, diluted version that avoids real rejection. The barrier isn't lack of research methods but fear of hearing 'no'. Surveys, friend feedback, and passive research feel like validation but avoid the hard moment of asking for commitment.

When to use

When you've done validation activities but haven't yet asked anyone to commit (pre-order, pay, or explicitly say no)

Don't do this

Treating friendly interest, positive surveys, or passive research as demand validation without testing actual commitment
