> You can't have less/more reliable knowledge. Science can't be half-wrong and half-right. You're either right or you're wrong.
No, you're either confident enough the theory holds - at least in some circumstances, confident enough the theory doesn't hold, or you can be not confident enough to say, but you can't ever say your theory is "right". See for example Newton's universal gravitation; it is "mostly right" for most use cases, but it is wrong when general relativity kicks in. And even general relativity is "wrong" when you go into particle physics. It's not as simple as "right or wrong".
