SUPPLEMENTAL LECTURETTE 2: THE RISE OF THE BIG FIVE2
This lecturette can be used to supplement the chapter’s coverage of the Big Five
personality dimensions (i.e., extraversion, agreeableness, conscientiousness,
emotional stability, and openness to experience). It describes the importance of
taxonomies (such as the Big Five) and then assesses the advantages and
disadvantages of using the Big Five as the dominant personality taxonomy.

Before 1965, research on personality and personality inventories was a popular
topic for industrial/organizational psychologists. However, an influential review
by Guion and Gottier in 1965 greatly influenced researchers away from
personality as a topic of study. Guion and Gottier concluded that personality
measures should not be used as a basis of decisions regarding employees.
Although their critique was largely based on the faulty research methods used to
study personality, their review was interpreted by others in the field as calling for
a moratorium on personality research. By the late 1980’s, researchers once
again picked up the banner of personality research. Partly responsible for this
change in status was the advent of suitable taxonomies by which to classify the
multitude of potential personality traits. This allowed researchers to explore the
relationship between personality and job performance within (rather than across)
personality constructs, resulting in significant relationships that were unknown
previously.
Taxonomies provide a classification scheme and as such facilitate the
organization and accumulation of information. An appropriate taxonomy is a
significant milestone in the gathering of knowledge. Useful personality
taxonomies must consist of traits that have been replicated. That is, traits within
the personality taxonomy should be replicated across different samples,
subgroups of people, time, cultures (if one wishes to generalize across cultures),
languages, measurement strategies (e.g., self-reported versus peer-reported
information), and data-analytic techniques. Second, the taxonomy should be
comprehensive in that it provides for the classification of all known personality
traits. Third, it should include traits having outside correlates. In other words, the
personality traits should be related to real-world outcomes such as job
performance.
So, how does the Big Five taxonomy stand up to these criteria? One of the
