Before we get to the juicy details of each personality, let’s take a quick stroll down memory lane. The 16 personalities aren’t just a trendy quiz result—they have a rich history grounded in psychology.

The Roots: Carl Jung’s Psychological Types

Back in 1921, Swiss psychiatrist Carl Jung published Psychological Types, proposing that people have innate preferences in how they perceive the world and make decisions. He introduced concepts like Introversion vs. Extraversion and Thinking vs. Feeling.

The MBTI: Briggs and Myers’ Legacy

During World War II, Katharine Cook Briggs and her daughter Isabel Briggs Myers expanded Jung’s ideas into a practical tool: the Myers-Briggs Type Indicator (MBTI). Their goal? Help people find careers that fit their personalities and improve interpersonal understanding.

The Modern 16 Personalities Framework

Fast forward to today, the MBTI has evolved with input from behavioral science and the Big Five personality traits. The popular website 16Personalities.com adds the Assertive/Turbulent dimension, making the model more nuanced.

Why It Matters

Despite some scientific debates about MBTI’s predictive power, millions worldwide swear by it for self-awareness, team building, and relationship insights. As Formpl.us notes, “Personality tests are a great way to discover your inner person.”
