Most people who say they believe in luck didn’t arrive at that belief through careful thinking. They inherited it. It came as a package from other people, from culture. And along with the belief came ready-made explanations.

You can see this clearly when you question it.

Whenever someone argues in favor of luck, the first thing you should do is simple: ask them to define it.

When you ask clarifying questions, the inconsistencies start to appear. People contradict themselves. Their answers shift. That’s a sign they haven’t thought it through. The responses they give are not really their own. They are repeating what came bundled with the belief.

Luck as an External Force

Luck as ‘factors and events that you have no control over’ is the most held interpretation of luck. I will start with questioning it and showing the problem with it.

If luck means an external force, something completely disconnected from your actions that determines outcomes, then believing in it is immediately problematic. It creates a gap between effort and result. It tells you that no matter what you do, something outside your control ultimately decides your success or failure.

Here’s the problem: once you accept that, you’ve already reduced your agency.

People often say things like “my luck is bad” or “my time hasn’t come yet.” What they are really doing is explaining away a deficit in action. More often than not, they are not acting boldly enough. Their efforts are inadequate. Luck just becomes a convenient explanation.

Now, the common defense is this: belief in luck helps people stay optimistic. It helps them stay resilient after failure. It gives them hope.

Sounds reasonable. But look closely.

If luck is truly an external force, then it is, by definition, disconnected from your actions. And if outcomes are disconnected from your actions, then your actions have less impact.

That can only reduce your agency, not increase it.

But when someone says belief in luck makes them more optimistic or resilient, what are they really claiming? They are claiming it helps them act more, persist more, and take more responsibility. In other words, they are claiming it increases their agency.

That is the contradiction.

Something that is defined as being independent of your actions cannot simultaneously be the reason you take more action. It cannot increase the very thing it is disconnected from.

To see this more clearly, compare two situations.

In the gym, outcomes are directly tied to your actions. The harder you train, the more consistent you are, the better your form, and the more progressively you increase resistance, the better your results. That clear link between effort and outcome naturally increases motivation. Your agency is reinforced, so you act more.

Now compare that to a pure gamble, where the outcome is completely disconnected from your actions. Whether you win or lose has nothing to do with how hard you try. In that case, there is no real incentive to improve your effort, because effort doesn’t change the result. Your agency is irrelevant.

When outcomes depend on action, agency increases. When outcomes are independent of action, agency decreases.

So if someone claims that belief in luck motivates them, what’s actually happening? If you push them further with this, people will say something like, “Believing in luck makes me take action, and taking action gives me results.”

What they mean is this: taking action increases their chances of success. It increases their exposure to opportunities. Now they’re essentially acknowledging that there are opportunities out there, but unless they move, they won’t come across them.

At this point, they are no longer talking about luck as an external force. They have already shifted the definition.

The Shift to “Luck as Opportunity”

This is where the argument naturally lands.

Once the idea of luck as an external force breaks down, luck is redefined as opportunity. As exposure. As being in the right place at the right time because you took action.

But notice what this implies.

Luck is no longer independent of action. It is now directly tied to it.

The more you act, the more people you meet, the more places you go, the more you increase your exposure to opportunities. What you call “luck” is now a function of your behavior. It grows with your agency.

At this point, the original belief has already been abandoned.

Because if outcomes improve as your actions increase, then luck is not a separate force influencing your life. It is simply a label being applied to the results of your actions.

So why call it luck at all?

Calling it luck only creates confusion. It shifts credit away from action and toward something vague and external. It muddies a simple truth: outcomes come from what you do.

And here’s the important point: If your action is already at its maximum, belief in luck cannot increase it. You cannot go beyond full effort. But belief in luck can reduce action. It introduces doubt. It creates room for passivity.

Any amount of belief that outcomes come from anything other than your actions (even if that is technically how it is) can only reduce your agency, thereby hurting your chances.

So, believing in luck does nothing at best. At worst, it holds you back.
