You’re standing on the edge. Not a literal cliff, usually. It’s more like a job offer that pays less but feels right, or telling someone you love them when you aren’t 100% sure they’ll say it back. We talk about it all the time, but when you actually try to define leap of faith, you realize it’s not just about being brave. It’s about the terrifying gap between what you can prove and what you need to be true.
It’s scary.
Honestly, most people spend their whole lives trying to avoid that gap. We want data. We want guarantees. We want a 5-star review before we even try a new taco spot, let alone change our entire career. But life doesn't always give you a spreadsheet. Sometimes, the only way forward is to jump into the dark and hope the ground shows up to meet your feet.
Where Does This Phrase Actually Come From?
If you want to define leap of faith properly, you have to go back to a 19th-century Danish philosopher named Søren Kierkegaard. He didn't actually use the exact phrase "leap of faith" in the way we do—he wrote about a "leap to faith"—but he’s the guy who gave the idea its teeth.
Kierkegaard was obsessed with the fact that you can't prove God exists through logic alone. He thought that if you could prove it, you wouldn't need faith at all. Faith, to him, required a level of "objective uncertainty." You have to choose to believe despite the lack of evidence. It's a conscious, messy, deeply personal decision. It’s not a blind stumble; it’s a deliberate act of the will.
Think about that for a second. If you have all the facts, it’s just a calculated risk. If you have zero facts and no skin in the game, it’s just a whim. A true leap of faith happens right in the middle, where you know enough to be interested but not enough to be safe.
The Science of the "Jump"
Neuroscience actually has some thoughts on this. When we face a choice with an unknown outcome, our amygdala starts screaming. That’s the "fear center" of the brain. It hates uncertainty more than it hates a known negative outcome.
A study published in the journal Psychological Science found that people would rather receive a definite electric shock now than wait for a possible shock later. We are hardwired to prefer certainty, even if that certainty sucks. When you define leap of faith in a biological sense, you’re talking about the prefrontal cortex—the logical, "human" part of your brain—overriding that primal lizard-brain fear of the unknown.

What a Leap of Faith Is NOT
People get this wrong all the time. They think jumping into a pool without checking if there’s water is a leap of faith.
It isn't. That’s just being reckless.
- It’s not ignorance. You should do your homework.
- It’s not a guarantee. You might actually fail. That's the whole point of the "leap" part.
- It’s not a one-time thing. Most big leaps are actually a series of small hops that eventually lead to a point of no return.
Imagine a startup founder. They don’t just wake up and quit their job on a coin flip. They research the market, they build a prototype, they talk to customers. But eventually, there comes a day where they have to quit their stable 9-to-5 to go all in. No amount of market research can tell them for sure if they’ll be bankrupt in six months. That moment? That’s the leap.
Real-World Examples: When Jumping Worked (and When It Didn't)
We love the success stories. Look at Sara Blakely. She was selling fax machines door-to-door. She had $5,000 in savings and an idea for footless pantyhose. She didn't have a fashion degree. She didn't have retail experience. She just believed in the product so much that she took the leap, cut the feet off her tights, and eventually created Spanx.
But for every Sara Blakely, there are thousands of people who took a leap and landed face-first in the dirt.
Acknowledging that risk is vital. If there was no chance of falling, we’d just call it "walking." The nuance here is that even the "failed" leaps usually teach you more than staying on the edge ever could. In the tech world, they call this "failing fast." You jump, you realize the idea didn't work, and you use that momentum to pivot to something that does.
Why We Struggle to Define Leap of Faith in Our Own Lives
It’s easy to define it for a movie character. When Peter Parker jumps off a building in Into the Spider-Verse, we get it. It’s cinematic. It’s heroic.

When it’s your mortgage, though? It’s a lot harder to see the heroism.
We live in a culture that worships "optimization." We have apps to track our sleep, our steps, our macros, and our productivity. We’ve been conditioned to think that if we just have enough data, we can eliminate risk. But the most important things in life—love, creativity, purpose—cannot be optimized.
You can’t A/B test a marriage. You can’t run a simulation on whether moving to a new city will make you happy. At some point, the data runs out.
The Psychological Payoff
There is a weird kind of peace that comes after you jump.
Psychologists often talk about "cognitive dissonance." When you’re standing on the edge, your brain is in a state of high tension. You’re torn between the safety of the "now" and the potential of the "next." Once you make the decision—once you commit to the leap—that tension often evaporates.
Even if the outcome is still uncertain, the decision is made. You've reclaimed your agency. You’re no longer a victim of circumstances; you’re an actor in your own story.
How to Take a "Smart" Leap of Faith
If you’re feeling the itch to change something big, don’t just close your eyes and hop. You can actually prepare for a leap of faith without stripping it of its meaning.

1. Define your "Floor"
What’s the absolute worst-case scenario? If you quit your job and the business fails, do you move back in with your parents? Do you take a temp job? Usually, the "floor" isn't as low as we imagine. Once you know you won't literally die, the jump feels a bit more manageable.
2. Audit your intuition
Is this a leap of faith or a leap of ego? Sometimes we want to jump because we're bored or looking for attention. A true leap of faith usually feels like something you must do, even if you’d rather not. It’s a calling, not a craving.
3. Check your "Why"
If you're jumping away from something you hate, you're just running. If you're jumping toward something you believe in, that's a leap. Make sure your motivation is based on the destination, not just an escape from the current reality.
4. Accept the lack of closure
You won't know if it was the right move for a long time. Maybe years. You have to be okay with living in the "maybe" for a while.
Actionable Steps for the Uncertain
Stop waiting for a sign. Honestly, the "sign" is usually just the fact that you can't stop thinking about the jump.
Start by identifying one area where you are over-analyzing. Maybe it's a conversation you've been putting off or a project you haven't started because you're waiting for the "perfect" time.
Here is how to move forward:
- Write down the "Unknowables": Make a list of things you simply cannot prove or predict about this choice.
- Set a Deadline: Give yourself a week to gather facts. After that, no more research. You either jump or you step back from the edge.
- Small Scale Testing: Can you take a "mini-leap"? If you want to change careers, can you do one freelance project first? It won't give you all the answers, but it builds the muscle.
- Acknowledge the Fear: Don't try to be "fearless." That's a myth. Just be "brave," which is doing the thing while your hands are shaking.
A leap of faith isn't about the landing. It's about the moment your feet leave the ground and you realize that you are finally, truly, in charge of your own life. Whether you soar or stumble, you’re no longer standing still, and in a world that’s constantly moving, standing still is the biggest risk of all.
