Second, what explains the attitudinal results? I argued that gift wrapping, through repeated pairing with joyous events in people's lives, has utility in cuing a happy mood which, in turn,…

Do we think people with beards are more trustworthy?
is research analyses the effects of endorsers' beardedness (i.e., the state of being bearded) on their perceived credibility and consumers' purchase intention for various categories of products.
