When boards evaluate CEO candidates or companies assess leadership potential, they often gravitate toward the most ambitious.
The logic seems sound: driven, competitive individuals who relentlessly pursue goals should naturally excel at the top. But data from the Hogan Personality Inventory (HPI), used by Fortune 500 companies worldwide, reveals something unexpected.
Extremely high ambition scores don't consistently predict executive success. In fact, they can sometimes signal future derailment.
Consider the CEO who prioritized personal legacy projects over market needs, or the executive whose political maneuvering fractured the leadership team.
These aren't failures of drive, they're failures of balance. Understanding what truly predicts leadership effectiveness requires looking beyond a single trait.
The HPI's Ambition scale measures drive, competitiveness, and goal-orientation, qualities that seem tailor-made for leadership. Boards and search firms naturally assume higher scores indicate stronger executive potential. After all, you need ambition to climb the corporate ladder, lead transformations, and deliver results under pressure.
But here's the paradox: At extreme levels, ambition creates predictable problems at the executive level.
Leaders with exceptionally high ambition scores often exhibit:
This is precisely why sophisticated organizations don't rely on the HPI alone. They pair it with the Hogan Development Survey (HDS), which identifies how personality traits can become derailers under stress. The combination reveals not just what drives someone, but what might derail them when the stakes are highest.
Here are some tips to get you started:
✔️Understand what’s being measured
The HPI tests seven traits linked to leadership. Study each one, focus on Adjustment, Interpersonal Sensitivity, Prudence, and Inquisitiveness, and practice relevant test questions.
✔️Avoid extreme responses
Moderate scores across traits are better than extremes. They show maturity and adaptability, key to senior roles.
✔️Answer authentically and consistently
Be honest and consistent. The HPI flags contradictions, so don’t try to game it.
✔️Focus on your complete leadership profile
Show how your traits form a strong leadership profile. Match your strengths to the company’s values using the Hogan scales.
✔️Prepare for the full Hogan suite

Effective C-suite leadership requires a constellation of integrated capabilities. Here's what the research shows matters most:
Adjustment: Composure Under Extreme Pressure
Adjustment measures emotional stability, confidence, and stress tolerance. For executives, this trait determines how you handle board presentations during crises, navigate activist investor challenges, or lead organizational transformations without losing your composure.
Leaders with strong Adjustment scores remain steady when others panic. They make clear decisions under ambiguity, inspire confidence during uncertainty, and recover quickly from setbacks. This stability creates the psychological safety that high-performing executive teams require.
Interpersonal Sensitivity: Stakeholder Management and Influence
Interpersonal Sensitivity reflects your ability to read others, build relationships, and exercise influence without formal authority. At the C-suite level, this translates to managing board relations, fostering executive team cohesion, and leading cultural transformation.
The most effective executives excel at building consensus among stakeholders with competing interests. They understand political dynamics without being political. They create alignment not through mandate, but through genuine connection and strategic influence.
Prudence: Strategic Foresight and Enterprise Risk
Prudence measures conscientiousness, planning ability, and attention to detail. For executives, this becomes strategic foresight, regulatory compliance awareness, and fiduciary responsibility.
Leaders strong in Prudence balance innovation with governance. They identify risks before they materialize, establish systems that scale, and make decisions with long-term value creation in mind. They're not risk-averse, they're strategically calculated.
Inquisitiveness: Vision and Market Foresight
Inquisitiveness reflects intellectual curiosity, strategic thinking, and openness to new ideas. This trait fuels the ability to anticipate disruption, reposition competitively, and lead transformations that others don't yet see coming.
Executives high in Inquisitiveness identify emerging trends that reshape industries. They ask the difficult questions that challenge conventional wisdom. They create space for innovation while maintaining strategic focus.
The key insight: Ambition provides the drive to pursue leadership roles, but Adjustment, Interpersonal Sensitivity, Prudence, and Inquisitiveness determine whether you'll be effective once you get there. C-suite success requires integrated capabilities across all these dimensions, not just relentless drive.
Not all leadership positions demand the same personality profile. A turnaround CEO facing an existential crisis may need higher ambition and risk tolerance to make bold moves quickly.
A stewardship-focused executive in a mature, regulated industry may need higher prudence and lower risk appetite. Innovation leaders driving new ventures require elevated inquisitiveness and comfort with ambiguity.
Even if the distinction between founder-CEOs and professional managers matters, founders often succeed with higher ambition and boldness, while professional managers in established enterprises typically need higher interpersonal sensitivity and prudence. Smart succession planning accounts for these nuances.
So what's the optimal ambition level? Research suggests moderate to moderately high ambition works best for most executive roles. Leaders in this range are driven enough to pursue challenging goals and overcome obstacles, yet grounded enough to prioritize organizational success over personal advancement.
They demonstrate healthy competitive drive without the restlessness that leads to frequent role changes, pursuing results while building collaborative relationships. They're ambitious for the organization, not just themselves.
This balance is exactly what employers using the HPI look for, executives who will push the organization forward without destabilizing it in the process. But ambition is just one piece of the puzzle.
Leadership effectiveness emerges from the interplay of multiple personality dimensions.
When evaluating executive talent, resist the temptation to prioritize any single trait. Instead, look for integrated capabilities across judgment, influence, strategic thinking, and composure under pressure.
The Hogan Assessment suite, combining the HPI's bright-side traits, the HDS's potential derailers, and the MVPI's values and motivations, provides this complete picture that organizations need for high-stakes leadership decisions.
Whether you're a C-suite leader evaluating talent, an aspiring executive developing your capabilities, or an HR professional planning succession, understanding these dynamics gives you a significant advantage.
And if you're taking the assessment yourself? Answer authentically. Sophisticated tools like the HPI include validity scales that flag inconsistent patterns. Authenticity serves you better than attempting to project an idealized image.
