b. Sensing or Intuitive (S or N).
c. Thinking or Feeling (T or F).
d. Perceiving or Judging (P or J).
3. These classifications are then combined into sixteen personality types. For example:
a. INTJs are visionaries. They usually have original minds and great drive. They are
characterized as skeptical, critical, independent, determined, and often stubborn.
b. ESTJs are organizers. They are realistic, logical, analytical, decisive, and have a
natural head for business or mechanics.
c. The ENTP type is a conceptualizer. He or she is innovative, individualistic,
versatile, and attracted to entrepreneurial ideas. This person tends to be
resourceful in solving challenging problems but may neglect routine assignments.
4. MBTI is widely used in practice. Some organizations using it include Apple
Computer, AT&T, Citigroup, GE, 3M Company, and others.
C. The Big Five Personality Model
1. An impressive body of research supports that five basic dimensions underlie all other
personality dimensions. The five basic dimensions are:
a. Extraversion. Comfort level with relationships. Extroverts tend to be gregarious,
assertive, and sociable. Introverts tend to be reserved, timid, and quiet.
b. Agreeableness. Individual’s propensity to defer to others. High agreeableness
people—cooperative, warm, and trusting. Low agreeableness people—cold,
disagreeable, and antagonistic.
c. Conscientiousness. A measure of reliability. A high conscientious person is
responsible, organized, dependable, and persistent. Those who score low on this
dimension are easily distracted, disorganized, and unreliable.
d. Emotional stability. A person’s ability to withstand stress. People with positive
emotional stability tend to be calm, self-confident, and secure. Those with high
negative scores tend to be nervous, anxious, depressed, and insecure.
e. Openness to experience. The range of interests and fascination with novelty.
Extremely open people are creative, curious, and artistically sensitive. Those at
the other end of the openness category are conventional and find comfort in the
familiar.
2. How do the Big Five traits predict behavior at work?
a. Research has shown relationships between these personality dimensions and job
performance.
b. Employees who score higher, for example, in conscientiousness develop higher
levels of job knowledge.
c. Conscientiousness is as important for managers as for front-line employees.
(Exhibit 5-1)
i. The study found conscientiousness—in the form of persistence, attention to
detail, and setting of high standards—was more important than other traits.
ii. These results attest to the importance of conscientiousness to organizational
success.
d. Although conscientiousness is the best predictor of job performance, there are
other traits that are related to aspects of performance in some situations.
3. All five traits also have other implications for work and for life. Let’s look at these
one at a time. (Exhibit 5-2)
