Workplace personality tests turn complexity into corporate color codes
Surrounded By Idiots
The episode connects a flimsy personality framework to a longer history of employment screening, discrimination, and efforts to individualize structural workplace problems.
- 1DISC reduces multidimensional, situational personality into four fixed categories without strong scientific support.
- 2Personality testing has long helped employers judge workers, often through intrusive questions and discriminatory assumptions.
- 3Color-coded assessments may prompt conversation, but they can also excuse harmful conduct and obscure management or organizational failures.
Don't miss
The hosts recast color-coded team exercises as a way for companies to blame personality mismatches instead of examining management, incentives, or organizational design.
The brief
Peter and Michael Hobbes take apart Thomas Erikson’s Surrounded by Idiots, beginning with its four-color DISC model and its promise to make communication easier.
The framework traces back to William Moulton Marston’s speculative 1928 theory, then turns personality into red, yellow, green, and blue categories that flatten context and contradiction.
The hosts argue that DISC lacks strong scientific support: self-reporting, vague claims, inconsistent assessments, and body-language advice cannot establish fixed personality types.
The episode widens its lens from Erikson to workplace testing, tracing how employers used intrusive personality questions and how discrimination challenges pushed companies toward friendlier-looking assessments.
Its sharpest conclusion is that DISC can make structural problems look like personality mismatches, even if an arbitrary exercise occasionally gets coworkers talking.
