Right. And I’m arguing that’s more of a fiction than House.

In most cases, waiting for a definitive test can be more harmful than treating when the preponderance of evidence points one way. (In some cases, the test is riskier than the treatment.)

Broadening out of medicine, it’s absolutely okay in many circumstances to try a fix before you’re sure you know what the problem is.
