YHPRUM's Law: Everything That Can Go Right, Will

Yhprum's Law is Murphy's Law read backwards, and it might be the more honest of the two.

YHPRUM's Law

Yhprum's Law says that everything that can go right, will go right. It's the mirror image of Murphy's Law, the optimist's rewrite of the same universe. Most of us never heard of it because optimism bias gets dismissed as naivety, while pessimistic thinking gets dressed up as realism. But flip the logic and something quietly powerful opens up.

The optimist sees opportunity in every difficulty. The coin is the same. It just depends which side you're watching.

The law you never knew you needed

Murphy's Law is everywhere. Coffee spills on white shirts. The lane you switch to slows down. The file corrupts the night before the deadline. We quote it like a prophecy.

Yhprum's Law never got the same press. But it deserves a seat at the table.

The claim is plain: everything that can go right, will go right. Read that and your first instinct is probably skepticism. It sounds like a poster in a dentist's waiting room. But stay with it.

Pessimism feels responsible. When you expect the worst, you look like a realist when things go badly, and pleasantly surprised when they don't. It's a bet with low social risk.

But here's what that framing costs you: action. If Murphy's Law is your operating system, every uncertain situation runs through a filter of anticipated failure. You delay, hedge, soften. You don't send the email. You don't start the project until conditions are better. Conditions never get better.

Yhprum's Law doesn't ask you to pretend failure doesn't exist. It asks you to weight the other side of the ledger. Planes land safely millions of times a year. Surgeries go as planned. People say yes. Trains run on time. The roof holds. Most of the time, an overwhelming amount of the time, the thing you were afraid of does not happen.

Everything that can go right, will go right. The question is whether you showed up to let it.

Yhprum's law optimism as a working posture

This isn't about magical thinking. It's closer to what Tali Sharot documented in her 2011 book The Optimism Bias: the human brain is naturally skewed toward expecting good outcomes, and that skew is often adaptive. It keeps us moving. It makes us start things. Optimism is not a flaw in the wiring. It might be the point of the wiring.

Apply Yhprum's Law as a posture and the math on action changes. You go to the audition. You write the first draft badly and finish it anyway. You book the trip. Because you're running on a different prior: things tend to work out for people who are there when they work out.

The coin, both sides

Murphy's Law and Yhprum's Law describe the same coin. Both are saying: in a world of uncertainty, outcomes multiply across all the things that could happen. One law focuses on the bad possibilities, one on the good. Neither is more scientifically accurate than the other.

So the choice isn't between truth and delusion. It's between two equally plausible readings of an uncertain world. One of them keeps you home. The other gets you out the door.

Pick the one that moves you.

Things go right all the time. We just don't write laws about those.

Yhprum is Murphy spelled backwards. Maybe that's the whole lesson. The same set of facts, read in a different direction.

Frequently asked questions

What is Yhprum's Law?
Yhprum's Law states that everything that can go right, will go right. It is the deliberate inverse of Murphy's Law, which holds the opposite. The name 'Yhprum' is simply 'Murphy' spelled backwards.
Who invented Yhprum's Law?
The origin is informal and not attributed to a single person. It emerged as a folk counterpoint to Murphy's Law, likely in engineering or productivity circles sometime in the late 20th century.
Is Yhprum's Law actually useful or just wishful thinking?
It's probably both, depending on how you use it. As a rigid prediction it fails often. As a working posture, a reason to act rather than hesitate, it has real practical value. Psychologists call the underlying mechanism 'positive expectation,' and it genuinely affects behavior.
What's the difference between Yhprum's Law and toxic positivity?
Toxic positivity denies problems. Yhprum's Law doesn't deny that things can go wrong. It just bets, consciously, on the possibility that they won't. The difference is that one is avoidance and the other is a choice about where to direct your attention.
