#513 The Half-Life of Knowledge and Experience: Why Modern Leadership Must Continuously Evolve
The Half-Life of Knowledge and Experience: Why Modern Leadership Must Continuously Evolve
In today’s business environment, knowledge is no longer a static asset. It is a rapidly depreciating resource. As Niels Brabandt highlights, the concept of the half-life of knowledge and experience has become one of the most critical leadership challenges of our time.
The half-life of knowledge describes the speed at which knowledge loses relevance. In industries such as technology, this cycle can be as short as 12 to 18 months. What was once considered cutting-edge can quickly become outdated. For decision-makers, this creates a fundamental shift in how leadership must be understood and practised.
Knowledge and experience remain essential. Knowledge provides the theoretical foundation, while experience enables practical application. However, experience alone is not sufficient. Without continuous renewal, it risks becoming obsolete or even counterproductive.
One of the central issues identified by Niels Brabandt is the illusion of timeless expertise. Many professionals, particularly those with long tenure, begin to believe that their accumulated knowledge remains valid indefinitely. This mindset often leads to resistance to change, undermining both individual effectiveness and organisational progress.
This resistance is particularly evident in leadership. Leaders frequently advocate for change, yet fail to embody it themselves. The gap between rhetoric and action erodes trust and prevents organisations from adapting to evolving market conditions.
At the same time, organisations face a structural shift. As experienced professionals retire, valuable tacit knowledge leaves the workforce. This knowledge cannot simply be replaced or replicated. It must be actively transferred, updated, and integrated into current practice.
The solution lies in a deliberate, science-driven approach to leadership. Niels Brabandt emphasises that evidence-based management must guide decision-making. Continuous education, professional development, and exposure to current research are no longer optional. They are strategic imperatives.
Organisations must institutionalise learning. This includes structured development programmes, access to high-quality training, and a culture that rewards intellectual curiosity. Importantly, education must be accessible within working hours, recognising that learning is part of the job, not an extracurricular activity.
Leaders who embrace this approach create organisations that remain adaptive, resilient, and competitive. They understand that knowledge must be constantly refreshed, and experience must be continuously reinterpreted in light of new realities.
The key message from Niels Brabandt is clear: leadership today is not about what you know, but about how quickly you can learn, unlearn, and relearn.

Niels Brabandt
We've always done it that way. You know, "I have the experience. I know how things go." Have you heard these phrases? Based on a huge amount of emails, I now have to pick up this topic. Often you see people saying, "I have the knowledge. I have the experience," and no question, knowledge and experience is great and extremely helpful. However, we have to know how to channel it properly, how to deal with it, and that's why today we're going to talk about the half-life of knowledge and experience.
Niels Brabandt
When we talk about the half-life of knowledge and experience, it's very obvious this is a massive reason of concern in many organizations because often people say, "Look, I really don't like to work with that colleague. He always wants to have it his way. He always says, 'I know how it goes.' He's not open for change. He will simply do it the way he always did it, and he simply doesn't want to change in any way." So we need to know how to do this better.
Niels Brabandt
First, of course, we have to talk about the situation in which we are. When we talk about half-life, people from physics and chemistry probably know what that is. Half-life, and I'm not getting into the physical-chemical aspect of this here, half-life basically means either the amount of knowledge doubled or your knowledge is worth half of what it was before. When you, for example, work in the tech industry, then the half-life usually is 12 to 18 months, and it's shortening by the minute. That means when you stay the same, your knowledge and your experience will be worth less because you didn't keep up with the pace of developments in your industry.
Niels Brabandt
And of course, we have two aspects of that: knowledge and experience. Knowledge is something you can read somewhere. Knowledge is something which can be acquired by, for example, formal education, professional education, executive education, university, vocational training, certificates, etc., etc. That is knowledge. The experience is what you get when you actually do the job. And here's the important use: you need both.
Niels Brabandt
When you only have the knowledge, you're an expert. However, you don't know how to put things in practice. I give you a very simple reason. When you ever heard of how to implement a software and you've never worked with users—users who probably do not have the affinity to tech as you have it—you can implement the software in theory as often as you like. As soon as you meet the real world, you will see that acceptance of software is a whole different ballgame, and that's where the experience comes in. Experience means you know not only how to have the knowledge but also how to apply the knowledge, especially with the human factor, with development, with everything that's external in an either complicated or even complex world. You know how to apply this properly in any situation.
Niels Brabandt
The question now is, why do we actually still face this situation with half-life of knowledge? What is the reasoning for that? And the reasoning for that has different aspects. So first, there is a very different perception of time. Let's say you work in the shipping industry or logistics, and you work in this industry for 30 years. You probably remember when you got into the industry and you learned lots and lots and lots of new stuff every single day, and then it somehow settled, and you thought, "Yeah, I think I know the most important aspect, and I actually know. I think it's going pretty well. I think I can handle it from here." So you suddenly think that what you know is timeless and what you do is timeless, and then you see change is happening.
Niels Brabandt
And here we come to a massive, massive issue. Way too often when we talk about change, especially the leaders who tell their people, "Hey, change is always an opportunity, always see the positive side of change," all of that is suddenly not applied by the leaders themselves. When you see that people say change is an opportunity, just remember when they talked about diversity back in the days. Suddenly, science found out diversity is beneficial for your organization, and then you suddenly didn't see boards changing. Executive boards remained the same. They say, "Oh yeah, we do the diversity bits, you know, somewhere on the operational level, somewhere there, but you know, on the executive level, we just keep hiring the same people from the same business clubs, right? We don't want to change that." They love to talk about change. They love others to change for them, for their favour, in their favour, but they do not change by themselves. And that's where the massive issue begins. People suddenly think, "I have the experience. I have the knowledge, so I know it all," and you simply have to step away from that aspect because society changes every single day.
Niels Brabandt
I give you a very simple aspect. Let's say 25 years ago, beginning 2000s or even in the 1990s, someone asked you about remote work. And of course, I know what's coming now. People say, "Well, back in the days, it wasn't possible because we didn't have the internet," right? Okay, look, here are the news. When we look into the development of the internet from DSL onward, as soon as we had DSL—I mean, with ISDN, I agree it was limited opportunities with remote work—but as soon as we had DSL lines, one or two MBIT back in the days, not even one MBIT, that was where you could do easy meetings. That's where Skybolts began. That's where you could meet. However, companies simply said, "No, no, you show up in the office every single day." Why? Because we always did it that way.
Niels Brabandt
Society, by the way, doesn't change the same way in every single country because some people might now say, "Wait, wait, wait, we adapted remote work way quickly, way quicker." And when you say that, you probably work either in the UK or in the US or in Canada, countries which adapted to remote work way quicker because, A, they are way larger, or B, they saw the opportunity, especially in the UK where they said, "We can't make people move to London anymore. It's getting more and more expensive." And by the way, it kept going ever since in that direction. These people then said, "Look, when we hire people from Scotland, they can work in Scotland, live in Scotland, and we can make them work for us in London without relocating." So they had the need for it.
Niels Brabandt
Society changes at different speeds. When you, for example, work in the German-speaking area, especially in Germany, remote work basically didn't happen before the pandemic. And after the pandemic, it was only there because now it was undeniably available, and employers couldn't pretend that they can't do it. So very important is society changes, and so do you, at least if you want to keep up the pace. So don't think anything you know is timeless. Don't think change goes past you, and don't think that societal changes can be ignored by you because as soon as you ignore one of these three, you will become the colleague where people say, "I'd rather not work with you because it's all a bit outdated and you're pretty stubborn, to be fair." So maybe just not you.
Niels Brabandt
The question now is, how can we do better? The implementation of that. As soon as we talk about implementation, the first thing is get awareness in. Get the awareness in that people actually know. And this is not about replaceability. It's not about telling people you're replaceable. It's about telling people everything we do, everything we know, meets an update from one day to the other. And the leading way is always by science. You need to tick the science bit, and this can be vocational training, certificates, ongoing training. Any kind of education brings you forward.
Niels Brabandt
If you think that your experience, your N equals one, your personal actions suddenly are facts, that is how nothing works. And by the way, I do not exclude my own industry here. When you see the amount of trainers, speakers, coaches, when you look on their LinkedIn profile, their last bit of updated education often is 20 years old. Do not get these people in your organization. They are not credible. They tell you outdated stuff. They tell you stuff that they read on internet blogs, and they say, "Oh, that's a catchy idea, so I'm going to pick that one up." The science bit needs to be done. I am undergoing ongoing education for one reason. I want my clients to receive the best knowledge they can ever get at every point in time possible. So be aware that this science aspect needs to be the leading aspect in addition to, of course, ongoing education.
Niels Brabandt
When you, for example, just a simple example here, AI, as soon as you talk about AI, you can't just tell people, "Well, let's go home," and just at home you could try Copilot or something. Yeah. And then you know how it goes. No, they don't because not every person has the same affinity to tech or progress or development. And some people simply with their families, children, whatnot, I'll simply have other things to do than doing their ongoing education outside of working hours.
Niels Brabandt
Professional education is an obligation for any modern organization. Bringing people forward, developing them properly, science-backed, by the way, which means someone needs the experience, the science-backing, and also the person delivering the education should be reasonably entertaining because otherwise you get boring really quickly. So it's important that the education is offered. It's also a massive reason for people to stay in your organization because they say, "Hey, mine still doesn't get outdated here," and that's why people love to stay. So be sure that you deliver on that promise as well because when you deliver on the promises that we just discussed about and you do it the way that we talked about here right now, then you will not have the issue with half-life of knowledge and experience. Then you will have a thriving organization where every single person works together. And I wish you all the best implementing this in your organization.
