I am not so sure it is a "myth". There is this old programmer.reddit post (http://programming.reddit.com/info/1kth0/comments http://programming.reddit.com/info/1kth0/comments) about an XP/TDD "guru" who does "exploration" with unit tests and another developer (a real guru this time, no quotes around the word) who doesn't. TDD is a valid technique when it fits. What's annoying is this tendency on the part of some of its practitioners to make it out into some kind of panacea.
