For example in one story Sherlock deduces that the person sending a ransom note is an educated man attempting to appear stupid, because although the note is grammatically incorrect the newspaper the letters are cut out from was The Times. And only educated men read The Times. Except....what if that's just coincidence? I mean The Times costs the same amount at a news stand as any paper right? So what if the kidnapper, who is so barely literate he doesn't read any daily paper at all, went to a news stand to buy something to cut the letters from and happened to pick The Times?
