If I had to pick one idea that explains how the world actually works — in business, government, economics, and even personal life — it’s this:
Incentives drive behavior
It’s not about what people say, believe, or intend — it’s about what they’re actually rewarded or punished for.
If you want to understand a system — why it’s thriving, failing, or spinning in circles — the most powerful question you can ask is:
“What’s the incentive?”
That single lens helps decode individual decisions, market outcomes, political ideologies, even entire economies.
Why Do Incentives Work? Evolution
Incentives work because they’re baked into how life survives. All living organisms respond to reward and punishment.
- Bacteria move toward nutrients
- Animals avoid pain and chase food
- Humans optimize for resources, safety, and status
We’ve layered institutions, money, laws, and culture on top of this base wiring — but the engine underneath hasn’t changed.
We move toward what helps us survive and thrive.
How Money Made Incentives Scalable
What makes human incentives unique is that we created a universal medium of exchange: money.
- Money is a shared fiction — a symbol we’ve collectively agreed has value
- It allows us to coordinate effort, trade across time and distance, and specialize
- And because people want more of it, we can use it to shape behavior at scale
People do mutually beneficial work — not out of charity, but because it pays. When millions of people operate under that system, it becomes:
A self-reinforcing engine of productivity, innovation, and rising standards of living
Capital flows to its most productive use. Talent is allocated. Problems get solved — not because someone said “be good,” but because doing the right thing pays.
The Deep Political Divide: What Drives Human Behavior?
Zoom out far enough, and the political spectrum is really a disagreement over this one idea:
Do people respond to incentives? Or can behavior be reshaped by systems and values alone?
The “Incentives First” view (Right-leaning economics):
- People respond to rewards and consequences
- Policy should align incentives with productive behavior
- If you want more of something, reward it. If you want less, stop subsidizing it
The “Outcomes First” view (Left-leaning economics):
- People are shaped by unjust systems, not just incentives
- Government should correct outcomes through redistribution and control
- People will behave better if we fix the environment they’re in
The first assumes human nature is flawed but predictable.
The second assumes it’s malleable and good at heart — and that smart planners can build a better system from the top down.
But here’s the catch:
To centrally reshape outcomes, you need designers who are smarter, more moral, and less corruptible than everyone else.
History shows us that’s rarely the case.
How Incentives Shape Systems
Here’s the full chain:
- Incentives determine what’s rewarded or punished
- That creates norms
- Norms shape the environment
- Environment drives behavior
- Behavior produces outcomes
- Outcomes feed back into the system — reinforcing what works (or doesn’t)
You don’t get a high-performing company, a thriving economy, or a functional society by accident.
You get it by designing a system where doing the right thing is also the rewarded thing.
Why This Matters
Because without this lens:
- We mistake symptoms for root causes
- We build systems that sound good but don’t work
- We expect people to act against their own self-interest — and get surprised when they don’t
But with this lens:
- You can predict behavior more accurately
- You can build systems that align rewards with good outcomes
- You stop being surprised — and start asking: what signal is this person responding to?
A Real-World Example: Investment Banking
In investment banking, managing directors are typically compensated based on revenue they generate. That revenue is often tied to closing deals — IPOs, M&A, financings — regardless of whether the transaction creates long-term value for the client.
The system rewards:
- Activity, not outcomes
- First-year revenue, not multi-year relationship health
- Transaction volume, not strategic fit
So what happens?
- MDs push deals forward — even if the timing isn’t right
- Clients get marketed to aggressively — even when doing nothing might be smarter
- Firms optimize for short-term revenue — not trust or reputation
This isn’t greed. It’s incentives.
The behavior is completely rational given the system they’re in.
Unless the bank rewires the incentive structure, this will keep happening — no matter how often leadership talks about “client-first values.”
