To highlight the persistence of the confusion compare the confusion matrix in two wikipedia articles: [1] and [2].

[1] https://en.wikipedia.org/wiki/Confusion_matrix

[2] https://en.wikipedia.org/wiki/Pre-_and_post-test_probability...

(In case edits are made one way or the other: both articles display similar confusion matrices but disagree on the names of the off-diagonal elements. In [1] false positives are called "type I errors" and false negatives are called "type II errors". In [2] false positives are called "type II errors" and false negatives are called "type I errors".)
