It really isn't; what's reasonable is to always assume whatever you thought of in 10 seconds, has been deeply researched regardless of whether you're aware of it or not. What's reasonable is to assume researchers are vast leagues ahead of whatever shallow thoughts you have on a subject since you "know" you have a shallow understanding. The reasonable person simply asks for links to read deeper about a subject, they don't criticize something they have a shallow understanding of and ask why no one is doing X.
