Boston Consulting Group ran an unusual experiment for its 2026 behavioral research. Researchers asked executives and employees how they felt about a change — after telling both groups they had no information about it at all. No type, no size, no impact. About 70% of executives said they felt positive. Less than half of employees said the same.
The data that got my attention
That optimism gap helps explain a number that has barely moved in 30 years: only one in four growth transformations succeeds. The failure rate sits near 70% and has not improved since the 1980s, despite decades of new tools, frameworks, and consulting methods.
Why this matters now
The volume of change is accelerating exactly when employee capacity for it is lowest. BCG’s May 2026 CEO survey found 90% of CEOs are increasing AI investment, and nearly three-quarters now put themselves at the center of AI decision-making. Each investment arrives as new workflows, tools, and role definitions for everyone below them.
Deloitte’s 2026 human capital research measured what the current pace is already doing to the workforce. The steady cadence of change has decreased well-being for 68% of workers, increased workload for 60%, and made 58% feel less relevant or left behind. Leaders are planning the largest change wave in a generation for a workforce that already describes itself as depleted.
What the research actually shows
BCG’s diagnosis is blunt: change does not fail because people resist it. It fails because leaders misunderstand how people actually change. Executives feel excitement and urgency, then assume that disposition is universally shared. Employees more commonly feel anxious, overwhelmed, or frustrated — and they need more information, attention, and support than executives expect. BCG calls the compounding cost of that mismatch the mathematics of misalignment.
Gartner’s workplace research extends the picture. The average employee now faces roughly 10 planned enterprise changes a year, five times more than a decade ago. Meanwhile, 79% of employees express low trust in organizational change, and only 32% of mid-to-senior business leaders say the last change they led achieved healthy adoption.
The scale of the perception problem is visible in the numbers below.
| Metric | Figure | Source |
|---|---|---|
| Executives who feel positive about a change they know nothing about | 70% | BCG, 2026 |
| Employees who feel the same | Less than 50% | BCG, 2026 |
| Growth transformations that succeed | 1 in 4 | BCG, 30-year record |
| CEOs increasing AI investment | 90% | BCG, May 2026 |
| Workers whose well-being declined from constant change | 68% | Deloitte, 2026 |
| Employees with low trust in organizational change | 79% | Gartner, 2026 |
| Leaders whose last change achieved healthy adoption | 32% | Gartner, 2026 |
The pattern is consistent across every major study: the people who design change experience it as opportunity, while the people who absorb it experience it as load. Traditional change management treats this as a communication problem. The data suggest it is a distance problem.
A practical framework for leaders
Closing the optimism gap is a repeatable management discipline, not a personality trait. Five moves make the difference.
- Treat your enthusiasm as data, not a plan. Before announcing anything, sample how managers and frontline employees actually feel about the coming change. Assume your read of the room is wrong until measured.
- Replace announcements with involvement. Gartner finds organizations that involve employees throughout a change are 14 times more likely to succeed. McKinsey finds companies that give 21% to 30% of employees formal roles in a transformation see the highest shareholder returns; most involve about 2%.
- Routinize change instead of staging it. Gartner’s 2026 CHRO research shows organizations where change is an instinctive part of daily work see three times higher odds of healthy adoption.
- Equip the middle layer. In a Gartner survey of 473 HR leaders, 74% said managers are not equipped to lead change. Talking points do not fix this; managers need time to process the change and practice the conversations before having them.
- Measure adoption, not announcements. Publish weekly behavior metrics. Only 32% of leaders could call their last change adoption healthy, which usually means nobody measured it.
The bottom line
The 70% number is not a leadership flaw. It is a measurement of distance. The farther leaders sit from the daily reality of the work being changed, the better change feels — and the worse it lands. Companies that close that distance before launch do not need bigger programs or louder messaging. They need smaller gaps. Thirty years of flat failure rates say the current formula is not working, and behavioral science now explains why transformations fail at the moment they are announced, not the moment they stall.
Where to go from here
Perception gaps are measurable before they become expensive. A structured change readiness review shows how leaders, managers, and teams each experience an upcoming change — and where the misalignments will bite first.
