The Foundations of DISC

DISC Profiling is grounded in the pioneering research of Dr William Moulton Marston, a psychologist who made significant contributions to understanding human emotions and behaviour. Marston introduced his DISC theory in his 1928 book, "Emotions of Normal People" (Marston, W.M., 1928). His research diverged from traditional psychological studies of the time by focusing on the behaviours of emotionally normal individuals rather than on mental illnesses.

The 4 Traits

Marston identified four primary behavioural traits: Dominance (D), Inducement/Influence (I), Steadiness/Submission (S), and Compliance/Conscientiousness (C). He proposed that these traits arose from people's interactions with their environment and their responses to external stimuli. Marston's theory was innovative in that it provided a framework for predicting behaviour based on these four dimensions.

DISC Came Later

Though Marston laid the theoretical groundwork, it wasn't until later that his ideas were developed into practical assessment tools. In the 1950s, Walter Vernon Clarke, an industrial psychologist, played a crucial role in operationalising Marston's theory. Clarke developed the Activity Vector Analysis, the first behavioural assessment based on DISC theory. His work translated Marston's conceptual model into a format that could be used to evaluate and predict workplace behaviours (source: "The DI(S)C Personality Profiler - Walter Clarke" on documents.pub).

Clarke's contributions were significant because they provided a method for applying Marston's theories in real-world settings, particularly in organisational contexts. His assessments helped employers with personnel selection, team-building, and understanding employee behaviours, making DISC Profiling a valuable tool for enhancing workplace dynamics.

As DISC Profiling evolved, further refinements and developments were made by other researchers and practitioners, which helped solidify its application in various professional settings. These efforts have ensured that DISC remains a relevant and widely used method for understanding and improving human behaviour within organisations.

In summary, the foundational research for DISC Profiling is primarily attributed to Dr William Moulton Marston’s theoretical work on human behaviour and emotions, with Walter Vernon Clarke's subsequent development of behavioural assessments transforming these theories into practical tools for the workplace. Their combined contributions have enabled DISC Profiling to become an essential framework for examining and optimising interpersonal relations in professional environments.
