There is no shortage of leadership development in the world. The global market is valued at roughly $366 billion. Organisations are spending more on it than ever before. And yet, by nearly every measure that matters, the investment is not working.
DDI's 2025 Global Leadership Forecast found that 71% of leaders report increased stress from their roles, with 40% of those stressed leaders considering stepping away entirely. Meanwhile, 77% of CHROs lack confidence in their bench strength for critical leadership roles. Trust in managers has fallen from 46% to 29% in just two years. Only 18% of organisations report that their leaders are "very effective" at achieving business goals.
These are not marginal findings. They describe a structural failure: we are investing unprecedented sums in developing leaders and producing historically poor outcomes.
The wrong diagnosis
The conventional response to this gap is to invest in more training — more programmes, more competency frameworks, more off-site retreats with post-it notes and breakout sessions. The underlying assumption is that leaders underperform because they lack skills or knowledge, and that filling those gaps will improve effectiveness.
This assumption is mostly wrong.
The leaders we work with at Perigon House are rarely short on capability. They have the strategic thinking, the domain expertise, the commercial acumen. What they lack is accurate information about how their leadership is actually experienced by the people around them. They are operating with a distorted map of their own impact.
This is not a personal failing. It is a structural one. Research consistently shows that as leaders gain authority, the candour of the feedback they receive declines. People edit themselves. They tell their leader what they think the leader wants to hear, or what will preserve the relationship, or what is politically safe. The information environment around a senior leader is almost always compromised.
The self-awareness dividend
Cornell University research found that leaders with high self-awareness — specifically, those whose self-ratings closely matched how others rated them — were 36% more likely to achieve above-average organisational performance. This is not a correlation buried in a footnote. It is a substantial, measurable performance advantage, and it comes not from learning a new skill but from seeing yourself more clearly.
The implication is uncomfortable for the leadership development industry: the single most leveraged intervention for most senior leaders is not a programme. It is a mirror.
What a better approach looks like
If the core problem is informational rather than educational, the solution looks different from traditional development. It starts with structured, multi-source feedback that gives the leader an honest picture of how they are perceived — and it continues with coaching that is grounded in that evidence rather than in abstract frameworks.
This is not a new idea. What is new is the urgency. The research from Phipps Cameron's 2026 leadership analysis puts it well: leadership effectiveness is now shaped less by tenure, role history, or technical expertise alone, and more by how leaders behave in practice — how they interpret uncertainty, create clarity, shape culture, and manage their own impact. These are behaviours that cannot be inferred reliably from experience alone. They need to be surfaced deliberately.
Three principles follow:
Make leadership capability explicit. Stop assuming that years of experience produce self-awareness. Most of the time, they produce confidence without calibration. Use structured 360° feedback and psychometric profiling to create an evidence base that the leader and their coach can work from.
Treat development as a team-level phenomenon. Individual coaching matters, but leadership effectiveness is increasingly a collective property. The most common failure mode we see is not a single underperforming leader — it is a leadership team that is misaligned on priorities, inconsistent in messaging, and operating with unspoken tensions that everyone can feel but nobody names.
Measure behaviour, not satisfaction. Gartner reports that fewer than 20% of HR leaders believe they can effectively measure the business impact of leadership development. Most still rely on completion rates and satisfaction scores. If you cannot demonstrate that leadership behaviour has observably changed in ways that others can validate, you are measuring activity, not impact.
The gap between what organisations spend on leadership and what they get for it is not inevitable. It is the product of a misdiagnosis. Leaders do not primarily need more knowledge. They need better information about themselves — and a structured process for acting on it.
That is a solvable problem. It just requires the honesty to start there.
