Occam's Razor
A simple cough hides a deadly secret—only the simplest explanation can save a young man's life.
"Occam's Razor" is the third episode of House M.D.'s first season, introducing the diagnostic team's signature method of prioritizing the simplest explanation. The story centers on a young man named Ethan, who presents with a persistent cough and fever. As the team investigates, they uncover a penicillin allergy and ultimately diagnose subacute bacterial endocarditis. While House's characteristic cynicism and unorthodox methods are on display, the episode focuses on the medical puzzle rather than a personal crisis for the doctor.

Lore & Background
The episode highlights the diagnostic team's early dynamic as they learn to navigate House's abrasive style. The medical mystery revolves around a seemingly simple case that defies easy answers, ultimately revealing a hidden allergy and a serious heart infection. Unlike later arcs, House's leg pain and addiction are not central; instead, the focus is on the team's first major collaborative challenge and the application of logical deduction to medicine.
In Their Own Story
The fluorescent lights of the diagnostic room hummed with an oppressive intensity, casting long shadows against the whiteboards covered in frantic scribbles. House leaned heavily on his cane, sweat beading on his forehead as a fresh wave of agony shot up his leg. He stared at the patient's chart, but the words blurred behind a haze of chemical fog. 'It's not the infection,' he muttered to himself, his voice raspy. 'It's never just one thing.' Yet, as he reached for another pill from his pocket, the realization struck him with the force of a physical blow: he was no longer solving puzzles; he was becoming the mystery everyone else was trying to solve.
Reader's Guide
The patient presents with seizures and confusion while pregnant, leading the team to suspect eclampsia or rare infections. Initial treatments fail as symptoms worsen, causing House to obsess over complex, unlikely causes like mitochondrial disorders. Red herrings abound as the team tests for everything from heavy metal poisoning to genetic anomalies, but none explain the rapid decline. The breakthrough comes when House realizes the patient's condition mirrors his own hidden struggle with pain and addiction, forcing him to look past the obvious medical data. The final diagnosis reveals a rare autoimmune reaction triggered by the pregnancy itself, which was masked by standard prenatal care. However, the true resolution involves House collapsing from an overdose attempt, exposing his addiction to Cuddy and Wilson, marking a catastrophic low point in his journey.
Did You Know?

- The principle is often paraphrased as 'of two competing theories, the simpler explanation of an entity is to be preferred'.
- William of Ockham himself never used the exact phrase 'Entia non sunt multiplicanda praeter necessitatem'; that wording came from John Punch in 1639.
- The term 'razor' refers to distinguishing between two hypotheses by 'shaving away' unnecessary assumptions.
- Occam's razor is used as an abductive heuristic in science, not as a rigorous arbiter between candidate models.
