I've done small surveys in college nothing big, but I had to follow the methodology that the professor specified, but just because I never went to France doesn't mean France doesn't exist. In other words, you don't have to actually do something for it to work. As far as the word of god comment, that sound like some dogmatic bullshit, which is the opposite of pragmatic knowledge, so perhaps this is where the disconnect lies.
Science stands on the shoulders with no requirements to actually reinvent shit from scratch just to prove that it actually works, for example, if I were to build a car, I would study schematics of current vehicles not go back to how the first engine was made.
Plus all that worshiping has nothing to do with science at all, every theory and law can be challenged and torn down, and if you are smart enough to do so then perhaps there is a noble prize in your future, but I must warn you ahead of time, debunking a tested scientific theory takes more than arm waving and nuh-uhing shit that doesn't coincide with your narrative!
Which leads to my next question, where do you get your information from, and how do you discern information that is presented to you, maybe you have a technique that supersedes the scientific technique, if so list it in detail, so folks don't think you are pulling shit out of your ass and guessing.
The floor is yours please answer this simple question.
