# Disproving Murphy's Law

Murphy's Law - "Anything that can go wrong, will go wrong" with and addition of "at the worst possible time", in Sod's Law or Finagle's Law.

Obviously this can easily be disproven by continous experimentation. I could be killed by Kronos right now(which is pretty wrong according to me), but it hasn't happened to me for 15 years. But is there a theoretical way to disprove Murphy's Law?

This note is for discussion on the above stuff, so no inappropriate comments and stuff.

And obviously no chatting, latex testing, or game/movie/shit discussions(Nathan).

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

I have a theory that we typically only start thinking of "Murphy's Law" when things go against us. For example, if I go for a drive, I probably won't notice if I get 5 green lights in a row, but I will notice (and get annoyed) if I get 5 red lights in a row, even if the probabilities are the same. That means our dataset is flooded with the times we remember when things go against us, which helps promote the idea of "Murphy's Law" even more. (I guess my theory is more psychological than mathematical.)

That actually makes sense. Murphy's Law was also created on the basis of Murphy's thinking, when he said something like, "If there are two ways to do something and one ends in disaster, he'll(the technician) do it that way." when a technician hooked up the sensors in the wrong way. Though it can still be shown by multiple experiments that Murphy's law is wrong, which also shows that Murphy's Law depends more on psychology.

My math is not as good as you are, but I'd say for example there are 5 laneways, the probability of ONLY your lane is blocked is 1/32, so if you increase the number of laneways the probability decreases. And whenever you change the route the probability of that lane blocked should stay the same. That's all I know, maybe it consists of the multiplication of probabilities, and please don't laugh at me if I'm wrong.

You're right, the probability is very less, which also hints that Murphy's law is wrong. No one's gonna laugh if you're wrong though.

i can disporve this if murphys law is that the wrong thing could happen at the worst time. if this was true something bad would happen when ido a test bc that is the worst moment for something to happen but so far noting has happened

i know my spelling is wron but idc my fingerrs r lazy

- 8 months, 2 weeks ago

ok (some text)

- 8 months, 2 weeks ago

Yes, but as I stated that is an experiment. I am trying to disprove it by theory. Like by calculating probabilities, or stating a scientific property that doesn't allow Murphy's law to happen.

Schrödinger's cat can disprove it

A cat is penned up in a steel chamber, along with the following device (which must be secured against direct interference by the cat): in a Geiger counter, there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges and through a relay releases a hammer that shatters a small flask of hydrocyanic acid. If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The first atomic decay would have poisoned it. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts. (WIKIPEDIA)

The worst that can happen is that the cat dies, but quantum theory points otherwise. According to current studies, if there is no observer, the object is placed in a superposition between the two, therefore 100% not allowing the worst to happen

Whoa, whoa, whoa, my brain is about to explode...

--some time later, Percy rebuilds his brain from the blown up bits--

Hey that's actually pretty cool!

afaik Murphy's Law is more stated like this: if there is a chance that a thing will break, then it will break if you just use it long enough.
and like David said: we will not remember the 9999 times that we used the thing and it works perfect, but we will remember that one time when it breaks.
and we will remeber this malfunction even more intense if a thing breaks when we need it very urgent.
and in such a moment of hurry humans are even more likely to forget that the thing already did a good job for a long time.

in my experience most humans are more likely to remember bad happenings than positive events.
