Is there a single word in English (or borrowed) that describes someone or some action as being clever or smart on the surface, but is actually quite foolish or unproductive?
I used to think "disingenuous" meant this (which of course it doesn't). The closest word I'd use would be something like "dis-ingenious".

If somebody says things that seem sensible, but are actually foolish or wrong, you can call their words specious.
