Reaccredited as a GCologist and Reminded of What Really Matters
by John Lyle, Read time: 4-5 minutes
I renewed my GCologist accreditation this week. Two years since the last one. In that time I've used The GC Index with clients across hiring decisions, leadership development, team diagnostics and coaching programmes.
I always come away with something new. This time was no different.
Let's start with SOME numbers FOR CONTEXT. They're ugly.
Gallup just released their 2026 State of the Global Workplace report — published this week. Global employee engagement has fallen to 20% — its lowest level since 2020 — costing the world economy an estimated $10 trillion in lost productivity.
It’s worth stating that again.: twenty percent. Eight in every ten employees, globally, are not engaged in their work.
I wrote about this dynamic back in 2021 when everyone was calling worried about "The Great Resignation." My argument then was that it was we might be seeing something more positive and exciting — a Great Resolution. Millions of people finally taking control of their careers, moving toward something better, choosing engagement over inertia. And I believed it.
Four years on, the data says something uncomfortable. The mobility happened. The moves were made. And yet here we are, back at pre-pandemic lows on engagement. Which means a lot of people moved — but landed in a new demotivational mismatch.
The problem was never just the job. It was the fit. And it was decision making.
The conversation that stays with me
This morning, the reaccreditation session with Nathan Ott and a group of fellow GCologists involved four case studies — real examples from around the world of how they had used The GC Index with clients. Not polished success stories. Real ones: with nuance, with the moments where the data surfaced something uncomfortable and/or insightful, and with the decisions that followed.
That's the part most people don't see when they first encounter this tool. They see a report. What they don't see is what happens when a leader reads a profile that explains, in clinical detail, why they've been misfiring in their current role. Or what happens when a team looks at their collective data together and suddenly understands why they're stuck.
The GC Index gives you language for things people already know but haven't been able to say. Or their own knowledge hasn’t dawned on them yet because they’re not having productive, vulnerable conversations that open things up.
What it measures — and why that matters
The GC Index measures Energy for Impact. Not personality. Not competence. Not potential. The specific, natural ways in which someone is energised to contribute to a role, a team, or an organisation.
There are five proclivities: Game Changers who drive transformational possibility; Strategists who bring direction and clarity; Implementers who build and execute; Polishers who raise standards and drive excellence; and Play Makers who create the conditions for collective performance.
None of them is better than the others. The insight comes from understanding which ones are present in a team, which ones are absent, and whether the energy in the room is aligned with what the business actually needs to do right now.
The hiring mistake nobody wants to admit
I've written before about the expensive mistake of hiring someone who looks great on paper — the awards, the billing history, the interview — and watching them struggle. In most of those cases, the problem wasn't capability. It was a failure to understand the conditions that produced their previous success, and whether those conditions exist in the new environment.
Here's what the industry doesn't talk about enough: a President's Club winner who thrived inside a well-oiled machine — strong brand, mature process, a full desk handed to them — may have been the right energy in the right conditions. That doesn't make them a fraud. But it does mean their results were partly a product of where they were, not just who they are. Strip away those conditions and put them somewhere that requires building from scratch, selling an unknown proposition, operating without infrastructure — and the results can be unrecognisable.
The same is true in reverse. Someone who is genuinely brilliant at building something new — a Game Changer who thrives on figuring it out, who does their best work when there's no rulebook — can look average or worse in an environment that no longer needs that energy. The machine has been built. Now it needs running. That is not their natural territory and the role will drain them. Slowly at first, then completely.
Gallup's research shows that when the fit is right and people are genuinely engaged, productivity increases by 23%, turnover drops by 51%, and wellbeing improves by 68%. That's not a soft HR story. That's a commercial argument. The inverse — the disengaged employee who is burning energy on the wrong work in the wrong environment — is part of that $10 trillion problem.
Most companies measure experience and personality. Almost none of them measure whether this person's natural energy matches what this team, this context and this leader actually need. That's the gap.
The GC Index makes this visible before it costs you. It's not just about who someone is. It's about whether your environment will bring out their best — or suppress it entirely.
What's changed in two years
A lot has evolved in the GC Index platform since my last accreditation. There's now ChatGCT — an AI tool built specifically around GC Index data that allows individuals and teams to explore how their profiles apply in real situations, available 24/7. GC Translate has also developed into something genuinely powerful: run any piece of written content — a job description, a set of company values, a meeting agenda — through it, and it reveals the energy for impact that content is actually communicating, whether you intended it or not. Run your job ad through it before you post it. You might be surprised what you're accidentally asking for.
Dr John Mervyn-Smith, one of the architects of the GC Index, has also co-authored a new book — The Psychology and Dynamics of Human Energy — with fifteen other GCologists. It's the deepest articulation yet of the thinking behind the framework and worth reading if you want to understand why this approach is fundamentally different from the personality tools that preceded it.
Why I keep using it
Most assessment tools give you a description of who someone is. Useful, to a point.
The GC Index tells you something more valuable: how someone is wired to make an impact, and what conditions will either unleash or suppress that energy. In a hiring decision, that's the difference between a successful long-term placement and an expensive mistake. In a leadership conversation, it's often the difference between a session that confirms what everyone already suspects and one that actually changes something.
Eight in ten employees globally are not engaged. The world is not short of smart, capable people. It is short of smart, capable people in the right conditions.
Nathan Ott's closing line to the reaccreditation group stuck with me: "Do good and be great".
That's a standard we should all hold ourselves to. That includes not just knowing how to run the GC Index tool — but knowing how to use the data to have the kind of conversation that shifts something real.
If you want to understand what The GC Index could surface for you, your team, or your next hire, I'd welcome the conversation.
