Meaning of "Einstein" by Kelly Clarkson

In "Einstein," Kelly Clarkson uses mathematical equations as metaphors to convey the emotional toll of being in a toxic relationship. The protagonist of the song reflects on their partner's lies, betrayal, and lack of respect, eventually reaching the realization that the other person is not worth their time or love. By referring to themselves as not being Einstein but still being able to understand that "dumb plus dumb equals you," the protagonist acknowledges that their partner's behavior is unacceptable and that they deserve better. The song captures the process of self-discovery and empowerment that occurs when someone comes to terms with the reality of a toxic relationship and chooses to end it, despite the pain it may cause.
