Relating this back to techie-problems, perhaps we need the moderate Practically Secure Crypto Hypothesis:

"You are astoundingly unlikely to create something better and more-secure from seeing a blog-post, reading some Wikipedia articles, etc. than a team of PhDs who did nothing but study mathematical theory, cryptography, and code-breaking for the last few years, and accordingly are vanishingly unlikely to create a new scheme which is more secure than existing standards once you account for performance and maintenance."
