I write Lisp/Scheme for living, but I'm not sure I can make such a bold statement (esp. how Lisp compares to other functional/logical languages---they do require different paradigm). But I can tell one thing from my experience: All competent Lisp programmers I know are also pretty good at C, C++, Java, or even Assembly. Even if they don't initially, they quickly become good. So, in empirical sense, using Lisp as one filtering factor can work. (But be aware: The fact that they can write good Java code doesn't mean they want to do so).
