Murphy’s Law, perhaps the most famous of all “life laws,” was coined in 1949 by Edward A. Murphy Jr., an aerospace engineer frustrated by a wrongly wired sensor during U.S. Air Force testing. His statement—“If there’s more than one way to do a job, and one of those ways will result in disaster, then somebody will do it that way”—quickly spread after Col. John Stapp mentioned it in a press conference.
But while Murphy’s phrasing was modern, the philosophy of misfortune has existed since ancient times. Roman playwright Plautus once wrote: “Things you don’t hope for happen more often than things you do hope for.”

What Murphy’s Law Really Means
Murphy’s Law isn’t science—it’s a folk adage. It teaches us three things:
- Human error is inevitable.
- Systems are fragile and prone to failure.
- Preparation reduces disaster.
Rather than pessimism, it’s a call for foresight.
