Three types of thinking that make complexity less scary

Complexity is a given. Whether it’s the tangled web of office politics, the swings of the stock market, or just figuring out why your Wi-Fi is slow, we’re constantly navigating layers of ambiguity. But let’s be real—most of us weren’t exactly handed a manual on how to handle the messiness of life and work.

That’s where three powerful ways of thinking come in: lateral thinking, systemic thinking, and first-principles thinking. They’re not magic tricks, but they do help you make sense of the chaos, cut through noise, and make better decisions. Let’s break them down.

Lateral thinking: because straight lines aren’t always the fastest route

Most people approach problems the way they walk through a hallway—straight ahead, step by step. Lateral thinking is more like parkour. Instead of trudging through obstacles, you vault over them by looking at the problem from unexpected angles.

How does it work?

Edward de Bono, who coined the term, argued that traditional logical thinking (a.k.a. “vertical thinking”) limits us to what’s obvious. Lateral thinking, on the other hand, is about deliberately shifting perspective—kind of like tilting your head to see a 3D picture pop out.

Someone who has been a teacher for years might think, “I can only apply for teaching jobs.” That’s a linear, vertical way of thinking—assuming that the job title defines the career path. But a more lateral approach would be to break the role down into its core skills:

• Explaining complex ideas clearly → Great fit for corporate training, instructional design, or even sales (convincing people is a form of teaching).
• Managing student behaviour and expectations → Transferable to customer service, HR, or client relations.
• Organising school events like recitals or field trips → Project Management experience.
• Handling parent-teacher communication → Experience in stakeholder management, similar to account management roles.
• Ensuring compliance with education policies → Could transition into policy writing, regulatory roles, or even consulting for education-based companies.

By shifting from “I am a teacher” to “I have skills in communication, project management, and stakeholder engagement”, entirely new career paths open up—without having to start from scratch.

How to flex your lateral thinking muscles:

• Ask “What if” questions: what if we did the exact opposite of what’s expected? What if this wasn’t a problem but an opportunity?
• Force connections: how would a chef solve this? Or a five-year-old? Or a musician? Borrowing perspectives can reveal surprising insights.
• Challenge assumptions: we take a lot of things for granted. If you assume something is “just the way it is,” that’s usually a good sign to question it.

Lateral thinking is particularly useful when you feel stuck. If the obvious answer isn’t working, maybe it’s time to take a detour.

Systemic thinking: seeing the whole web, not just the spider

Ever heard someone say, “Everything is connected”? Well, they’re not wrong. But actually seeing those connections—that’s systemic thinking. It’s about recognising how different elements, actions, decisions interact, rather than treating things as isolated problems.

Why does this matter?

A linear-thinking Project Manager might focus on keeping tasks on schedule: Is everyone meeting deadlines? Are we on track? A systemic-thinking PM looks deeper: How do team dynamics, business goals, and external dependencies interact? Where are the hidden risks? Projects don’t exist in a vacuum—they depend on a larger system:

• Deadlines aren’t just dates—they’re connected to business strategy. If a feature is delayed, it might impact a product launch, which could affect marketing campaigns and revenue projections. A systemic PM communicates risks early and ensures alignment across teams.
• Teams aren’t just task-doers—they’re interconnected systems. Engineering, design, sales, and support all have different priorities. A systemic PM doesn’t just assign work; they ensure teams have what they need, resolve conflicts, and remove blockers before they cause delays.
• Bottlenecks aren’t always where they seem. A slow engineering sprint might not be due to slow developers—it could be caused by late design handoffs, unclear requirements, or shifting priorities from leadership. A systemic PM traces issues to their root cause instead of treating symptoms.

By thinking systemically, a PM doesn’t just track deadlines—they ensure all moving parts work together, anticipate problems before they happen, and keep the entire system running smoothly.

How to apply systemic thinking:

• Map the moving parts: draw out the relationships between different factors. If sales are down, don’t just look at marketing—think about customer experience, product quality, market shifts.
• Look for unintended consequences: quick fixes can create new problems. Raising salaries might attract talent, but does it create resentment among existing employees? Consider second- and third-order effects.
• Think in loops, not lines: feedback loops drive most systems. If you only treat symptoms, the core issue keeps coming back (think of companies that constantly “reorganise” without ever fixing internal dysfunction).

Systemic thinking forces you to zoom out and understand complexity instead of oversimplifying it. And honestly, most big problems don’t have simple answers.

First-principles thinking: stripping problems down to their core

If lateral thinking helps you break out of rigid patterns and systemic thinking helps you see the bigger picture, first-principles thinking gets to the root of the problem.

What does that mean?

Most people approach work the way it’s always been done—whether it’s handling meetings, structuring their day, or managing projects. A first-principles thinker, however, doesn’t just follow the script. They break work down to its core truths and rebuild their approach based on what actually makes sense. Imagine someone constantly feeling overwhelmed at work. A default response might be: I need better time management.

A first-principles thinker would break it down:

• What’s actually making me overwhelmed? Too many tasks, too many interruptions, unclear priorities.
• Why do I have too many tasks? Am I taking on unnecessary work? Is everything actually urgent, or just poorly communicated?
• What’s the real goal? Getting the most important work done without burning out.
• What’s a better solution? Instead of just trying to “manage time better,” they might challenge how work is structured—setting clearer priorities, automating repetitive tasks, or renegotiating deadlines instead of just working longer hours.

By questioning the way work is typically done, a first-principles thinker solves problems at the root instead of just reacting to symptoms.

How to use first-principles thinking:

• Break things down: ask, “What are the essential facts here?” If you’re launching a startup, don’t just copy competitors—analyze what really drives customer decisions.
• Challenge cost assumptions: if something is expensive, ask, “What makes it expensive?” Sometimes, the price tag is more about tradition than actual cost.
• Rebuild from scratch: once you’ve stripped an idea down, build up a solution based on what actually makes sense, not what’s been done before.

First-principles thinking is hard because it requires deep questioning. But if you want breakthrough ideas instead of small improvements, it’s the way to go.

The bottom line: think better, solve smarter

The world isn’t getting any simpler. But complexity doesn’t have to be intimidating. By combining lateral thinking (breaking patterns), systemic thinking (seeing connections), and first-principles thinking (getting to the core), you can approach challenges in a way that’s both creative and effective.

Next time you’re stuck on a problem, ask yourself—are you looking at it the right way? Or is it time to think differently?
