Of course. But that applies to ideas broadly, whatever you happen to be working on.
Whereas the OP apparently wants something like a top 10 list of brilliant humanities insights, which is a misunderstanding of what students are learning: skills, not atomistic facts.
Even in the sciences, students are learning skills, not just facts and equations. The key is the ability to use them, and that takes a lot of practice. The result is a skilled scientist, not a container of facts.
> > "here's a brilliant humanities insight which can be applied to tech"
You are making a strawman of what OP said.
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.
Hell, I can come up with one myself:
"The medium is the message." - Marshall McLuhan
On second thought, perhaps it's both after all :P
That's certainly a simple universal aphorism.
By itself, though, it's completely useless.
This is not intended as an insult to Marshall McLuhan. It would be an insult to reduce his work to a pithy quote. As I said, there's no substitute for doing the work. One has to study his work, not just grab excerpts.
