  Lewis Goldberg is an America psychologist,  a Senior Scientist at Oregon Research Institute and an Emeritus Professor at the University of Oregon.

Goldberg is widely known for his Five Factory Model theory or The Big Five Personality traits.

The five factor model is a tool for studying personality. It is a personality test that consist of 5 main dimensions that broadly describe human personality. Depending on the score of one's test, a person may score high or low on each of the 5 dimensions. 

Those who score low on openness don't tend to want to explore, be creative, come up with new ideas, try new things, and the like familiarity. Those who score high are curious, imaginative, are open to new things and new ideas.

People who are low on conscientiousness  are lazy, disorganized and are negligent. People who score high are opposite. They are hard working and progressive.

Extroverted individuals are lively, talkative and social. Introverts are loners, quiet and passive.

Those who are low on agreeableness are ruthless, critical, and suspicious. Those who are high on agreeableness are trusting, light-hearted and good natured.

People low on neuroticism are calm and unemotional, and those who are high on neuroticism are emotional, worried and self-concious.

There is no grey area, and that is a flaw since people can be an open individual with, aspects from both the low and high end of the scale. It is also questionable as to whether a test can predict future behavior of individuals since peoples' attitudes and way of thinking can change over time from early adolescence to late adulthood.
