I know it's hard to believe at first, but the more you think about it, the more it makes sense. He has a complete lack of social skills and was diagnosed with mental disability in the episode "Petarded" (which people on the lower functioning realm of the spectrum have frequently been misdiagnosed with) and while usually appearing to be an idiot, he has an incredibly large knowledge base regarding popular culture (particularly television and film), being able to reference the most obscure and esoteric episodes of TV series and make unusual insights about them. Had this knowledge existed in virtually any other field than popular culture, he would not be seen as an idiot but a savant.
Peter Griffin's just an idiot. Nothing more, nothing less. If I see an episode where he starts talking about quantum theory or philosophy than I might have to reconsider my stance, until than I have to conclude that Peter's social skills are a result of his stupidity.
