A posteriori, Latin for "from the latter", is a term from logic, which usually refers to reasoning that works backward from an effect to its causes. This kind of reasoning can sometimes lead to false conclusions. The fact that sunrise follows the crowing of a rooster, for example, doesn't necessarily mean that the rooster's crowing caused the sun to rise.
