SalesFit vs Myers-Briggs (MBTI)

Myers-Briggs classifies people into 16 personality types based on four dichotomies: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, Judging/Perceiving. SalesFit measures the competitive wiring that predicts whether someone will close deals — a fundamentally different question.

The Core Difference

MBTI is a self-insight tool. It helps people understand how they prefer to think and communicate. SalesFit is a predictive hiring tool. It answers: will this person hit quota?

Why MBTI Falls Short for Sales Hiring

MBTI has no predictive validity for sales performance. The academic consensus since the 1990s is that personality type does not reliably predict job performance. ENTJs do not outsell INTPs in controlled studies. Drive, economic motivation, and resilience — the dimensions SalesFit measures — do predict performance. Personality type does not.
