The Science Behind DISC Influence

The DISC model's Influence dimension draws from William Moulton Marston's research on how individuals interact with their environment and other people. The Influence factor specifically measures how people approach social situations and attempt to shape others' perceptions.

Research Foundation

Marston identified that high-I individuals demonstrate:

• Confidence in their ability to influence others' opinions and behaviors
• Natural tendency to seek social interaction and approval
• Optimistic view of people and social situations
• Comfort with being the center of attention in group settings
• Preference for collaborative rather than competitive approaches

Contemporary DISC assessments build on this psychological foundation with extensive validation across different industries, cultures, and role types. Our DISC test incorporates modern research while maintaining the scientific rigor that makes behavioral assessment valuable for workplace applications.

I Personality Variations

High-I personalities express Influence differently based on their secondary DISC dimensions. These combinations create more nuanced behavioral patterns that provide deeper insights into individual working styles and preferences.

Common I Combinations

• ID (Influence + Dominance): Charismatic leaders who inspire action and drive results
• IS (Influence + Steadiness): Warm team players who build consensus and maintain harmony
• IC (Influence + Conscientiousness): Thoughtful communicators who blend enthusiasm with analysis

Understanding these combinations helps predict how individuals will perform in specific roles and what management approaches will maximize their effectiveness and job satisfaction.
