“Use a platform like user interviews.com or respondent.io to recruit users who have used similar solutions in solving the job to be done... give them a load of bogus options in there that they don't know what's the right answer. Don't ask them hey have you struggled with this painpoint yes or no because everyone will just say yes.”

Recruit interview subjects from competitor user pools and bury the pain in decoys

Pre-launch apps can still do JTBD research by recruiting on UserInterviews.com or Respondent.io from people who use a competing solution. Critically, never ask leading yes/no pain questions — bury the real pain among plausible decoys so participants can't pattern-match to what you want, and the genuine priorities surface.
