How the Sans MBTI test operates

The test is designed for velocity. Every prompt is tagged with an axis, a direction, and a weight. Likert answers translate to -2…+2 impulses and flow into a scoring engine that prefers clarity but gracefully flags ambiguity.

Scoring stack

Weights & math

  • Likert inputs remap to -2…+2 waves and multiply by weight.
  • Each axis normalizes its total weight so you see consistent percentages even when questions expand beyond 64.
  • Borderline triggers at 0.25 confidence, producing the retake-shortlist button.
Pair intelligence

Consistency pings

  • Related prompts share a pairId. If you spike opposite answers, we log a contradiction.
  • Each contradiction chips away at overall confidence up to 0.2 to keep overconfident types in check.
  • You can always clear or re-run the sequence—progress lives in localStorage.
