Can you judge a person by the looks ?

I feel looks are quite deceptive. A person loking so smart and handsome may not be kind from his heart or helpful which otherwise his appearance gives an imression! On the otherhand the person whom we think, as a wicked one , comes out to help you by going out of his way ! Have you experienced any thing like this? Have you every time found that your predictions about a stranger's behavious coinsided with your presumptions? Please let me know the ways , how you make out an out line about any one's personality from his looks? Thanks!
