I answered your first question in my original comment. People can build reputations with good science. I’ll answer the other one now. I think humans operate on faith in others’ testimonies way more than actual science. As a follower of Jesus Christ, this doesn’t bother me since I believe we learn the truth in multiple ways. However, science is rooted in empiricism which says any belief must be proven, independently reviewed by skeptics, and we keep using it while it seems correct. Dissent is always allowed in real science since our models (beliefs) might be useful but incorrect on some level. Whatever survives the most review with the most utility is what we should keep using. What happens is often different. People believe something just because it was reported somewhere or had a name on it. That’s pure faith (or argument from authority). Many works aren’t just unreplicated: they can’t be replicated. Many institutions have political biases affecting their work. Many don’t allow dissent on some topics. People good at one thing often fail at another. I also see big jumps in extrapolating a small success to future, larger successes. While common (even on HN), none of that is the scientific method in action. It’s more like a mix of science, unproven dogma, speculation, political maneuvering, and a popularity contest. The ratios of these vary by field and institution. Don’t call anything science or “proof” unless it fully follows the scientific method. And builds on premises that did, too.
