History Lesson
Carl Jung published his theory of Psychological Types in 1921
He proposed that each person has a preferred Orientation for directing mental energy, either outward, toward people and things – (E) Extraversion, or inward, toward ideas and concepts – (I) Introversion.
He also proposed two methods of gathering information and two ways of making decisions about that information:

Information gathering by means of the five senses (S) Sensing
Information gathering by means of insight (N) Intuiting
Making decisions about that information objectively (T) Thinking
Making decisions about that information subjectively (F) Feeling
Jung believed that we use all of these mental mechanisms, with a relative preference for one of each pair.
In the 1940s, Katharine Briggs and Isabel Briggs Myers recognized another pair of mental mechanisms in Jung’s work.
This pair of mental mechanisms describes how people operate in the world, either by evaluating information against stored preconceptions preferring to have things decided – Judging (J) or by taking information as it comes in preferring to leave decisions open – Perceiving (P).
The Myers-Briggs Type Indicator (MBTI) identifies 16 psychological types which are referred to by an abbreviation of four letters – one letter selected for each preference between the pairs of opposites.
The MBTI is widely used to help individuals make informed decisions on a career choice.

In the 1970s, David Keirsey applied his knowledge of Jung’s Mental Mechanisms and the MBTI letter-code designations to associate human behavior with four fundamental temperaments.
He published his theory of four fundamental temperaments and sixteen role variants in the book, co-authored with Marilyn Bates, titled Please Understand Me. Keirsey related his own observations of human behavior with historical, philosophical, and literary comparisons of character.

Artisan (SP): free-spirit, impulsive
Idealist (NF): search for self, helpful
Rational (NT): abilities, self-judging
Guardian (SJ): duty, useful
Keirsey’s Temperaments correspond to a subset of the letter-code combinations of the MBTI system.
Later in the 1970’s, Don Lowry simplified much of the complicated psychological language by assigning each temperament an easy to remember color.
Educator and playwright, Don Lowry studied under David Keirsey. He called his system True Colors and ingeniously introduced the four temperaments to the general public through interactive theater productions.

Orange (SP): positive, hands-on, entertaining
Blue (NF): spiritual, emotional, intuitive
Green (NT): inventive, analytical, determined
Gold (SJ): practical, dependable, consistent
Don felt that color expressed a feeling-tone which would make it easier to remember each style.
In 2001, Mary Miscisin published the book Showing Our True Colors, helping Don Lowry reach a larger audience and contributing her findings for how to apply personality concepts to improving communication and reducing stress.
Mary and Don share a passion for providing personality education as interactive entertainment.
In time, it became clear that there was a need for a modern system using everyday language to help individuals comprehend and discuss the way they see the world and how they interact with others.
In 2014, Mary Miscisin, M.S. and Ed Redard, M.D. founded Personality Lingo.
Mary’s book Showing Our True Colors was revised and published under the title Personality Lingo.

Mover (SP-Orange): values freedom
Connector (NF-Blue): values relationships
Thinker (NT-Green): values competency
Planner (SJ-Gold): values responsibility
Personality Lingo’s modern terms used to describe the personality styles make the insights of Keirsey’s Temperaments more accessible to everyone.
Personality Academy builds upon the mission of Personality Lingo to use everyday language to help you comprehend and discuss the way you see the world and how you interact with others.
Personality Academy terms to describe the Jungian Mental Mechanisms:
- The “Feeling” function becomes “Making Decisions Subjectively”
- The “Thinking” function becomes “Making Decisions Objectively”
- The “Judging” function becomes “Planned Mode of Operation”
- The “Perceiving” function becomes “Spontaneous Mode of Operation”
- The “Sensing” function becomes “Hands-On Gathering of Information”
- The “Intuitive” function becomes “Theoretical Gathering of Information”
By modernizing the terms used to describe the mental mechanisms, Personality Academy aims to bring the powerful insights of Carl Jung’s psychological type theory to a wider audience. The goal is to help students, parents, and teachers communicate more effectively with each other.
