Seven Blindspots
Why C-Suite Candidates Fail and How to Help Them Break Through
Why do some executives reach the top while others—with equal intelligence, experience, and ambition—stall just short of it?
Drawing on twenty-five years assessing and developing more than 3,000 senior leaders, Nathan Jenner reveals seven recurring blindspots that determine who thrives at the top and who, despite visible strengths, stalls. These gaps are rarely detected in traditional interviews or performance reviews, yet they surface with force once a leader steps into the role.

The Seven Blindspots
Each chapter opens with a real executive whose blindspot surfaced under assessment—what their organization missed, what it cost, and the development work that closed the gap when it was closable.
Confusing Clarity with Persuasion
They fail to inspire stakeholders to action—even brilliant analysis gets brushed aside, and good ideas stay inert.
Getting Trapped in Execution
They struggle to release the behaviors that earned their advancement—their focus on executing and optimizing today's plan becomes insufficient. Without the ability to sense the future and position their organizations accordingly, even operationally brilliant leaders plateau and their enterprise stagnates.
Succeeding Through Heroics, Not High-Performing Teams
They cannot build high-performing teams and are forced to trade their role as strategic architect for that of referee. Their days are consumed by managing friction, confusion, and underperformance—while the enterprise bleeds talent and momentum.
Dismissing Organizational Power and Politics
They treat organizational power and politics as an alternative to merit, rather than an essential complement to it—and lose the ability to mobilize the organization.
Mistaking Debate for Sound Decision-Making
They cannot facilitate high-stakes group decisions—leaving collective intelligence on the table, allowing obvious options to crowd out creative alternatives, and mistaking polite silence for commitment.
Preaching Change, Not Rewiring Behavior
They approach change as a communication and project management challenge rather than a human and structural one—winning intellectual agreement while failing to rewire behavior, leaving the organization stalled as the market moves on.
Rubber-Stamping CEO Succession
The board and the CEO treat executive succession as a rubber-stamp exercise, rather than a rigorous alignment of mandate and capability. This leads to selecting the wrong leader entirely or suffocating a new CEO under hidden friction and misaligned expectations.
