Isn’t this exactly the right approach? Create a public laboratory. The people inclined to attack us aren’t generically stupid, they are certainly brainstorming on their own. I say have contests, give people prizes for the best ideas, publish all of it. If we haven’t had the idea how can we guard against it? Of course there’s a risk that we’ll give an effective idea to someone. The converse risk, that someone will have an effective idea that we haven’t prepared for seems far graver.
