The failure of an interesting hypothesis is informative as long as you understand why it doesn’t work, and can better model how the thing you’re studying works. The difference between CS research and business is that business failures can sort of “come out of nowhere” (“Why isn’t anyone buying our product?” can’t really be answered), whereas, if you look closely enough at the models, you can always learn something from the failure of something that should’ve worked but didn’t.
