What we don't use

  • Glassdoor, Levels.fyi, salary.com, Payscale — self-report aggregators have selection bias toward users who post. We may reference these as a labeled secondary signal for tech-specific total comp where BLS top-coding obscures the upper tail, but never as primary.
  • LinkedIn salary insights — proprietary, opaque sample, can't be third-party-validated.
  • Survey panels — non-representative; opaque weighting.
