What is Myers-Briggs (MBTI)?

MBTI has been around a long time and is a common personality assessment tool in large companies. If you have worked at a large company, chances are that you have taken an MBTI assessment.

Katherine Briggs and her daughter Isabel Briggs Myers were the researchers who formalized the MBTI concepts starting with Katherine's work in 1917. Their work attracted others who helped formalize a methodology for psychometric testing along with statistical analysis for validation.

Wikipedia describes the Myers-Briggs Type Indicator assessment as " a psychometric questionnaire designed to measure psychological preferences in how people perceive the world and make decisions." It is based on 8 characteristics, 4 pairs of seemingly opposed traits. The opposing trait pairs are:

Extroversion (E) – (I) Introversion
Sensing (S) – (N) Intuition
Thinking (T) – (F) Feeling
Judging (J) – (P) Perception

The resulting personality score looks like a set of 4 letters from each pair. For example: ESTJ or ISFP or ENFP and so on. The definitions of each of the 8 traits are a little involved, so we will not cover them here.

What is DISC?

DISC is a human behavior model originally presented by Dr. William Marston in 1928. DISC has gained widespread popularity primarily due to the simplicity of the concept.
Marston's DISC model essentially had 2 sets of opposing traits instead of 8 as in the MBTI concept. While Marston used different terminology in his early writings to explain the traits, we have chosen explain those traits in more understandable intuitive terms as follows:

Outgoing or Reserved
Task-oriented or People-Oriented

The combination of traits results in 4 main possibilities that correspond to 4 letters: D, I, S and C. The diagram below shows the Outgoing trait on the top of the diagram, the Reserved trait at the bottom, the Task-Oriented trait on the left side of the diagram and the People-Oriented trait on the right. Each corner or quadrant represents two traits together - symbolized by a single letter (D, I, S or C).


Understanding human behaviour and personality is an essential element of communication and engagement.

Thing about the people, their behaviour and personality when planning communication and engagement.
