A surprising amount of leadership appointments are still made on gut feel.
Think about it: Someone interviews well. They've got the right experience. They seem like a good fit. So you promote them.
Then six months later, you're dealing with the consequences. They're technically brilliant but can't lead people. They either avoid difficult conversations or become controlling under pressure.
The problem isn't that these traits were hidden. They were always there. You just didn't have the data to see them.
That's what Hogan Assessments actually do. They show you how people really behave, not how they present in interviews or how they think they come across.
According to Hogan's research, based on profiling over five million leaders globally, between 40% and 50% of senior leaders fail to meet expectations within 18 months of appointment. Not because they're incompetent. Because their behaviour under pressure derails them.
The confident person becomes arrogant. The detail-focused one becomes a perfectionist who slows everything down. The decisive leader turns controlling.
These patterns are predictable. But most organisations don't look for them until it's too late.
Hogan removes the guesswork. It measures three dimensions that actually matter: how people behave day-to-day (the bright side), how they behave under pressure (the dark side), and what actually motivates them (the inside). That combination shows you the full picture, not just the polished version people present in interviews.
According to Hogan's research, most people have two or three high scores here. Even moderate scores can be meaningful. Everyone has derailers. The question is whether you know what yours are and whether you manage them.
When leadership teams have misaligned values, they make decisions differently and prioritise differently. That creates friction even when everyone's technically competent.
When you profile a leadership team with Hogan, patterns that were invisible before become obvious.
You see who thrives under pressure and who struggles. You identify where personality clashes are causing problems. You understand why some leaders can't seem to delegate or why others avoid accountability.
That clarity changes how you make decisions about succession, development, and team composition.
For example, you might have two potential successors for a role. On paper, they're equally qualified. But their Hogan profiles show completely different patterns. One scores high on Bold and Mischievous, comfortable with risk, willing to challenge convention. The other scores high on Diligent and Cautious, methodical, risk-aware, and focused on quality.
Neither is better nor worse. But they'll lead differently. And if you don't know which style the role actually needs, you're guessing.
Here's what makes Hogan different from most assessments: it measures reputation, not identity.
Identity is how you see yourself. Reputation is how others see you. And there's usually a gap.
Most people think they're more collaborative, more open to feedback, and better under pressure than they actually are. That's not arrogance, it's human nature. We're terrible judges of our own behaviour.
Reputation is what matters because it's what determines whether you get promoted, whether your team trusts you, and whether you can actually lead effectively.
Hogan is validated using observer descriptions of behaviour. It shows you how you're likely perceived by others, which is often very different from how you perceive yourself.
The most effective use of Hogan Assessments isn't just profiling individuals. It's profiling entire leadership teams to understand dynamics. You can see where roles are duplicated and identify where values clash.
That data creates a shared language for leadership. Instead of vague conversations about "communication styles" or "cultural fit," you're discussing specific patterns backed by evidence.
It also removes politics from succession planning. When you have objective data on how someone performs under pressure, development conversations become clearer and fairer.
Most importantly, you stop relying on gut feel and start using data that's been validated across millions of leaders over three decades.
