Thomas Erikson is the author of Surrounded by Idiots, a book that simplifies four basic personality types using a coloring system and a two-by-two matrix.

In this conversation, we address:

• the difference between the four letters in DISC and the colors
• the purpose and role of personality assessments in the workplace
• the validity and reliability of such assessments
• the three parts of the human mind

Some people believe personality assessments are bogus. Others live and swear by them. Regardless of where you are on this spectrum, we address the questions you have about any type of personality assessment.
