Understanding DISC

Millions of professionals have used the DISC personality assessment to improve their relationships, build stronger teams, and communicate more effectively.

What is DISC?

DISC is a personality profiling and behavioral assessment tool created by Harvard graduate and PHD psychologist William Moulton Marston in 1928. It's evolved over the decades, and is now used by millions to better understand themselves and others.


Out of all the personality frameworks out there, why use DISC?

The advantage to DISC is that it's a behavioral assessment tool- it determines personality types using observable human behavior. Behavior is something we can obtain data on, and therefore study and use to make reliable predictions regarding future behavior.

DISC Types

DISC uses four primary behaviors to determine someone's personality type. A person might best be described as one type only, a combination of all four, and anything inbetween! The four types are:

D - Dominant

When someone has a D personality type, they are by nature outgoing and task-oriented. A D is direct, assertive, and decisive. They seek challenges and control, and are very comfortable with conflict.

I - Influential

Individuals with the I personality type are outgoing and people-oriented. They're confident, enjoy people, and get excited to explore fresh ideas and new projects. I's are sincerely interested in the feelings of others, and generally considered to be charming by those they interact with.

S - Steady

People with the S personality type are by nature reserved and people-oriented. They are innately supportive, sympathetic, and place high value on positive interactions. An S enjoys routine, consistency, and cooperation.

C - Calculating

Someone with the C personality type is by nature reserved and task-oriented. They are very analytical, detail-oriented, and logical, ignoring emotions and quickly changing their mind when presented with new information. C's naturally gravitate toward process, structure, and rules.

DISC doesn't try to determine someone's personality exactly. It's best to to think of DISC as describing someone's natural behavioral tendencies. It's completely possible that someone falls into a particular behavior style, but has overridden a natural "weakness" associated with that type.

It's also important to recognize that no type is better or worse than the others, they're just different!

When should I use DISC?

DISC is valuable for all sorts of reasons, but some of it's most valuable applications are:

  • Empowering individuals to discover their natural strengths and weaknesses, sources of stress, and motivators.
  • Quickly identifying the personality types of others, enabling you to better understand, communicate, and work with others.
  • Assisting with hiring, team formation, and management.
  • Educating a salesforce on different personality types and how to communicate with them, assisting with relationship building and business development.

If you're working with people on a regular basis, you're certain to find some value in DISC.
