The Commercial Evidence
Jonathan Griffiths is an award-winning, UK-based keynote speaker on celebrating brilliant humans and workplaces. This page is for the people asking the most important question any decision-maker can ask before booking him: what's the business impact?
Why it matters
It's a fair question. And the honest answer is that the qualities Jonathan's research identifies as defining brilliance — kindness, empathy, and inspiration — are not in tension with business performance. They are, by some margin, the most reliable drivers of it.
The evidence below is drawn from some of the largest workplace studies ever conducted: Gallup's Q12 meta-analysis of 2.7 million employees, Google's Project Aristotle, Amy Edmondson's twenty-five years of research at Harvard Business School, and — most recently — the Global Workplace Happiness Report 2026 and the IC Index 2026.
None of it is Jonathan's opinion. All of it points in the same direction.
Five research pillars
Gallup Q12
2.7 million employees, 96 countries, 54 industries. The largest workplace study ever conducted.
Google Project Aristotle
180 Google teams studied over two years. The world's most data-driven company studying itself.
Amy Edmondson, Harvard
Twenty-five years of research on psychological safety. The academic standard on high-performing teams.
Global Workplace Happiness Report 2026
Over 80,000 working people across 115 countries. 1.9 million data points on what actually drives happiness, productivity, and retention.
IC Index 2026
5,000 UK workers. The UK's most comprehensive annual research into trust, communication, and leadership — published May 2026.
Gallup Q12 meta-analysis — 2.7 million employees
Gallup has run its meta-analysis on employee engagement ten times. It remains the largest workplace study ever conducted. The pattern is consistent across industries, geographies, and two decades of data.
Business units in the top quartile of employee engagement — the teams where people feel genuinely seen, heard, and valued — outperform bottom-quartile business units on every commercial measure that matters.
These are not wellness outcomes. They are P&L outcomes.
The cost of getting it wrong
The cost of disengagement is now quantified with considerable precision. Gallup's 2026 report found that global employee engagement has fallen to just 20% — its lowest level since 2020 — and estimates that low engagement cost the world economy approximately $10 trillion in lost productivity last year, roughly 9% of global GDP.
At the organisational level, the estimated cost of a single disengaged employee is 34% of their salary per year.
For a 100-person business with a median salary of £75,000, that is over £430,000 lost annually — not to resignations, but to people who remain at their desks while quietly disengaging from the work.
The absence of kindness, empathy, and inspiration in a workplace is not a cultural inconvenience. It is among the most expensive operational failures a business can tolerate.
And the problem is accelerating. The 2026 Gallup data reveals a manager crisis at the heart of the decline: manager engagement has fallen from 27% to just 22% — a five-point drop in a single year, while individual contributor engagement barely moved. The people who set the weather for everyone else are running out of energy themselves.
180 teams. Two years. One finding.
In 2012, Google launched Project Aristotle, a two-year internal study of 180 of its own teams. The aim was to identify what separated the highest-performing teams from the rest. Google expected the answer to be about talent density, individual brilliance, or team composition.
It wasn't.
The single strongest predictor of high-performing teams was psychological safety — the shared belief that team members can speak up, admit mistakes, ask questions, or raise concerns without fear of humiliation or punishment.
The commercial outcomes for those teams were unambiguous. Teams with high psychological safety had lower turnover, harnessed more diverse ideas, brought in more revenue, and were rated as effective twice as often by management.
Psychological safety is not a personality trait. It is a climate, built from the same qualities Jonathan's research identifies as defining brilliance: kindness in how mistakes are handled, empathy in how dissenting views are received, and inspiration in the form of leaders who model curiosity rather than certainty.
The world's most data-driven company studied itself for two years and concluded that the single biggest differentiator between its best and average teams was how it felt to work on them.
2023 meta-analysis — psychological safety and output
For leaders whose objection is that innovation, not kindness, is what they need — this is where the evidence is most difficult to argue with.
A 2023 meta-analysis in the Journal of Applied Psychology found that teams with psychological safety exhibit 27% higher innovation output, driven by increased idea-sharing and experimentation. Employees in psychologically safe environments are seven times more likely to experiment with novel solutions.
The qualities many executives dismiss as soft are the operating system for the creativity and innovation they say they want. You do not get one without the other.
The silence problem
One further finding deserves attention from every executive team.
Research by Amy Edmondson and James Detert found that 85% of employees have withheld important information from their manager because they feared the consequences of speaking up.
Eighty-five percent. The overwhelming majority of people in any given organisation are, at any given moment, sitting on something their leader needs to know. A risk. An idea. A customer signal. A concern about a colleague.
The cost of that silence rarely appears as a line on a P&L. It surfaces instead as failed projects, missed opportunities, preventable errors, and the slow, quiet disengagement of people who decided, at some point, that speaking up was not worth it.
80,000 workers. 115 countries. 1.9 million data points.
The Global Workplace Happiness Report 2026 surveyed over 80,000 working people across 115 countries. Its most important finding may also be the most damning indictment of how organisations currently operate.
Organisations are investing most in what matters least.
The analysis found that the strongest predictors of happiness at work are inspiration and belonging — the emotional, cultural dimensions that depend on how people feel about their organisation and their place within it. The weakest predictors are workload management, role clarity, and job requirements: the rational, operational dimensions that tend to receive the most organisational attention.
In other words, the things that score highest in the survey matter least to happiness and engagement. The things that score lowest matter most. The same pattern holds for productivity, advocacy, and retention.
Acknowledgement and Personal Growth — the dimensions most dependent on leaders who notice, recognise, and invest in their people — sit at the bottom of global rankings in virtually every country. Yet they are the strongest correlates of whether someone will stay, perform, and recommend their employer.
The report also carries a striking financial finding. An investment fund that ranks public companies by the quality of their employee relationships has beaten the S&P 500 in 16 of the 19 years since its inception, posting a 12.5% annualised return against the benchmark. JP Morgan's independent research confirms the finding holds across time, market cap, and industry. The intrinsic factors — trust, inspiration, connection, belonging — are not just good ethics. They are a measurable, investable commercial edge.
The IC Index 2026 — the UK's most comprehensive annual research into internal communication — reinforces the picture. Less than half of UK employees feel able to share their opinions without fear of negative consequence. Fewer than half understand why the changes happening around them are happening. The qualities that rebuild both — clarity, candour, and the human willingness to listen and respond — are precisely what Jonathan's research identifies as the foundation of brilliance.
The connection to Jonathan's work
Jonathan's 2026 research asked 105 people what they most associate with brilliance in others. The top three answers — kindness, empathy, inspiration — were not chosen because they sound virtuous. They were chosen because they are the qualities people recognise in the humans who have genuinely shaped their lives.
Five independent research bodies — Gallup, Google, Edmondson at Harvard, the Global Workplace Happiness Report, and the IC Index — tell the same story from the commercial side. Engagement, psychological safety, inspiration, belonging, and trust — the outcomes every organisation is trying to drive — are built on the same qualities Jonathan's research has already surfaced as the definition of brilliance.
This is the argument at the heart of every keynote Jonathan delivers. It is not a case for being softer. It is a case for taking seriously what decades of workplace research have been saying: the qualities that define brilliance in humans are the same qualities that define performance in organisations.
Brilliant Humans Research 2026
105 people asked what they most associate with brilliance in others
#1 answer: Kindness & empathy — chosen by 54% of respondents
86% said they were most shaped by people the world has never heard of
11% never told that person what they meant — because they ran out of time
These are the same qualities Gallup, Google, and Edmondson identify as the foundation of high-performing workplaces
Engaged teams are measurably more productive, more profitable, and more loyal. Psychologically safe teams innovate faster, catch mistakes earlier, and speak up before problems become crises. The Global Workplace Happiness Report confirms that inspiration and belonging — not workload tools or org charts — are what actually drive happiness, productivity, and retention. Only 37% of employees feel their company genuinely cares about them. Just half of UK employees trust their leaders. The qualities that close those gaps — kindness, empathy, inspiration — are the qualities Jonathan's research identifies as defining brilliance. The leaders who understand this will quietly outperform the ones who don't.
