Everyone in Joseph Andrews seems to want something from our poor hero, and few of them have any qualms about resorting to shady tactics. Parson Adams and Fanny Goodwill may be on the up and up, but basically all of the minor characters justify messing with Joseph's head in order to get at their baser desires: sex for Lady Booby, Mrs. Slipslop, and Betty, and money for just about everyone else.
So, is Joseph really as gullible as he seems? We'd say that he's at least a little wise to the ways of the road. It's better to be underestimated than totally predictable, after all.
Still, he's pretty gullible.
