While there are - no doubt - many counter-examples (or what appear to be counter-examples) I have never been able to shake the conviction that a goatee beard is phony. This does not mean that the person with a goatee is a complete phony - but that insofar as he sports a goatee, to that extent at least he is a phony.
Why would this be? I think because a goatee requires that a man shaves every day, just as if he were clean-shaven - yet leaves this little tuft, which must indeed be rather carefully shaped and trimmed. It seems like none of the benefits of allowing a beard to grow, and all the disadvantages of shaving with added ones.
As to whether it looks good?... Well, let us just say that it may sometimes improve the appearance of some people.
But there is always that danger that anyone who has a goatee for any significant length of time will develop the habit of stroking it. And that simply adds to the problem.
The problem? In a word: smugness.
A goatee looks smug - leading to the question: "What does he have to be so smug about?"
Which prompts the thought that if he really had cause to be smug - then why is the goatee necessary?
