I think "stupidity" as a specific set of traits that people can express either occasionally or continuously. I don't think stupidity is the same as lack of intelligence or wisdom. Highly intelligent people can behave stupidly, too. I spent a lot of time thinking about this. I arrived that stupidity is lack of intelligence/wisdom AND/OR inability to make use of intelligence/wisdom. For example, one way you can be intelligent and yet stupid is if you lack self-reflection and/or are dishonest with yourself. This impairs ability to acquire wisdom -- honest observations about truth of yourself and the world around you, may make you repeat same mistakes without realizing what is causing them, etc. Being unable to learn from your mistakes (maybe because you are not honest enough to recognize them as mistakes or recognize true causes) basically prevents you from advancing as human being. If your level of advancement is below your age you might be labeled as "stupid".
