When attractive people are being rated by someone who does not know what they look like (e. g., over the phone), they are rated as being than unattractive people?

The answer is they are rated that beautiful is good. We seem to use the basic stereotype that what is beautiful is good; we accept that attractive people have desirable traits that complement their desirable appearances and we seem to make these judgments automatically, without any conscious thought; a beautiful face triggers an optimistic assessment the moment we see it.
