I don't think so. Is the OP not asking for some kind of simple universal aphorism? On the contrary, I think that the OP is making a straw man out of the humanities.

The usefulness to tech of those trained in the humanities is not to apply a few "brilliant" insights but rather to apply their "ordinary" but trained insights every day to ordinary tasks. In a meeting, you might say, "That's a good idea, Chris", but it would be so specific to the task that you couldn't state it as a "brilliant humanities insight". What you want is someone who "thinks different", as the saying goes.
