• Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
  • All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
  • All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.


The first experiment already illustrates a truth of the theory, well confirmed by practice, what-ever can happen will happen if we make trials enough.
Augustus de Morgan, 1866

Murphy's Law is the most commonly used term for the infamously pessimistic maxim, "Anything that can go wrong, will go wrong.".[1] However, on this wiki, it references quite a few things, so we've made this page to help people figure out which one they really want.

If you want...

  • ...the trope as applied to fiction, it's under Finagle's Law.
  • ...the webcomic, it's under Murphy's Law (webcomic).
  • ...the trope about a bed that traps people, it's Murphy's Bed.
  • ...the UK drama series with James Nesbitt... you'll have to make a page for it.
  • ...the law as laid down by Alex Murphy, that's RoboCop.

The actual Murphy's Law is more nearly "If parts can be assembled a right way and a wrong way, they will be assembled the wrong way." Study, for instance, the loss of several F-111 (TFX) aircraft during the Vietnam War due to the backwards insertion of a graphite pin in the rudder assembly.

  1. The actual Murphy's Law is something different, although most people refer to it in this form, which is why we have Finagle's Law
