About Character Intelligence
A Movement Whose Time
Has Come.
For decades, organizations have relied on two pillars when evaluating talent: intelligence (IQ) and emotional intelligence (EQ). However, there is a critical third dimension that determines whether even the brightest leaders succeed or fail under pressure: Character Intelligence.
With the vast majority of hiring failures stemming from character and attitude issues, we can no longer afford to ignore this blind spot. In an era where generative AI has made it trivially easy to fake polished credentials and a perfect résumé, Work Character is the only reliable signal left.
This is not a philosophical discussion about virtue—it is a practical blueprint to stop measuring false signals and start building teams that thrive under pressure.
Our Story
Why We Started: We Ran Out of Patience for Brilliant Jerks
The idea for Character Intelligence didn’t begin in a research lab; it was forged through expensive mistakes and high-stakes crises.
We (Sean and Jen) arrived at this work from completely different worlds, but we kept seeing the exact same pattern. As a serial entrepreneur and tech founder, Sean watched a "perfect-on-paper" hire with flawless credentials quietly destroy a startup's culture, costing the company dearly in lost productivity and driving top talent out the door. As a Chief Medical Officer, Jen saw how a lack of Work Character—such as a toxic attending physician silencing a resident from speaking up—became a literal life-or-death patient safety issue.
We realized that regardless of the industry, organizations don’t fail for lack of talent; they fail because they tolerate toxic high performers who erode trust and psychological safety. We wrote the book and built this community because we wanted to create the operational blueprint we wished we had decades ago.
What We Believe
Principles That Guide Our Work
Work Character is a Force Multiplier.
True character is observable behavior under pressure. It is built on six non-negotiable traits that act as a developmental ladder: Integrity (the foundation), Respect (honoring others), Humility (welcoming growth), Accountability (owning outcomes), Confidence (lifting teams), and Grit (sustainable stamina).
We Must Stop Measuring False Signals.
Hiring based on résumés, "culture fit," and personality tests often rewards performative charm and polish over actual substance. We believe in structured, evidence-based systems that measure who a person really is when the stakes are high.
Character Can Be Developed.
Work Character is not an immutable personality trait; it is a practice. While everyone starts from a different place, these traits can be systematically developed through clear expectations, micro-behavior habits, and honest, direct feedback.
Character Must Be Financially Material.
What you tolerate becomes your standard. If an organization promotes or heavily bonuses a toxic high-performer, it teaches the entire company that character doesn't matter. We believe in evaluating and rewarding employees equally on what they achieve (results) and how they achieve it (character).

The Movement
The Line in the Sand
The Character Intelligence movement is not owned by one person or one book; it is a call to action. We believe it is time for leaders to stop staying quiet and draw a visible, unmistakable line in the sand regarding the behavior they will and will not tolerate.
Cultural change doesn't start with consensus—it begins when a small, brave group decides to raise the standard. Through our frameworks, toolkits, and the Character Intelligence Manifesto, we are giving organizations the infrastructure they need to build systems others can copy.
If you believe that it's time to let the good inherit the work, we’d love for you to join us.
