THE POWER OF READING PEOPLE

Exploring Behavior Through Established Models

The landscape of behavioral models is rich and ever-expanding,
with many frameworks drawing from the same foundational theo-
ries. Among these, TTI Style Insights assessment stands out for its
robust, time-tested approach to understanding human behavior.
This model traces its lineage back to the pioneering work of psy-
chologist Carl Gustav Jung, incorporating insights from Jolande
Jacobi and the innovations of American psychologist William
Moulton Marston. Jung’s categorization of “attitudes” and “func-

tions” remains a pivotal method for classifying diverse behavioral
styles. Frank M. Scheelen’s book Knowledge of Humanity at a Glance
states (Scheelen, 2018, p. 25):

“By attitudes, Jung means the obvious preferences of a person
for the ‘inner’ or the ‘outer’ world. If a person orients himself
toward the external world, his thoughts, feelings and actions
relate to the objective, material world. Extroverted people, as

they are also called, develop an idea because they see a flower
or a telecommunications tower, and that inspires them to do
something, gives them something to think about, or makes
them happy.

“Those who are oriented toward the inner world, i.e., who are in-
troverts, are more focused on their own inner life. He deals with
his feelings, values, and thoughts and draws inspiration from

them. For example, an introverted person is motivated to do a
job because they like their teammates or the task corresponds
to their values. An extroverted person is motivated because he
receives a company car or receives a lot of attention from those
around him through work. The terms ‘introversion’ and ‘extro-
version’ express the direction in which someone mainly directs

their energy: inwards or outwards.”
