Personality can be defined as “the combination of stable physical and mental characteristics that give the individual his or her identity” (Kinicki & Kreitner, 2006, p. 132 ). The dimensions that make up personality include thoughts, emotions, and behavior patterns (Robbins & Coulter, 2009). Personality has quantifiable aspects that remain stable throughout a person's life. The Myers-Brigg Type Indicator and the Big Five model are personality assessments that attempt to classify observable behavior. Some organizations use these assessments when hiring employees, placing them in an appropriate position, and promoting these individuals within the organization. Personality assessments can also be used effectively in groups within the workplace as a tool to maximize productivity by facilitating better communication and cohesion. The Myers-Brigg Type Indicator (MBTI) was developed by two non-psychologists, Myers and Brigg, who produced a personality analysis assessment based on the work of psychologist Carl Jung (Coe, 1992). Jung theorized that human behavior can be predicted by an individual's personality (Kinicki & Kreitner, 2006). This type theory suggests that we have an innate preference for “paired opposites” based on four dichotomies: energy, information gathering, decision making, and lifestyle (Daft & Marcic, 2009, p. 390). The MBTI assessment is used to determine where you get your energy in social situations (extroverted or introverted), how you prefer to gather information (sensitive or iNtuitive), how you tend to make decisions (feeling or thinking), and what your decision-making style is is (perceptive or judging). Extroverts tend to “talk to think” and derive energy from interacting with other people (Coe, 1992, p. 512). Intr......middle of paper......eopathy. Similar.
