Not really. Common sense is not enough by itself. You need to investigate and educate yourself quite a bit before you can determine that the Watchtower organization plagiarized and embellished their stories from other sources.
I think the Toto Illustration explains the process you are referring to. The primal sense is, in his case, his nose. He didn't have to act on his sense, but he did because he didn't have any reason not to since he was not afraid. The process of educating ourselves could be compared to Toto's act of pulling the curtain back. For us, it happens much slower than it did for Toto.
