I wasn't trolling, but I think you might be?
Of course science can be more/less reliable or half-wrong/half-right. The truth isn't binary, it's closer to fuzzy logic sets.
And as much as you would like to call the "soft" sciences pseudosceince, you are doing yourself a disservice. In reality, your attitude suggests that you are closer to a pseudoscientist than the "soft" scientists you are so eager to dismiss. Narrow-mindedness like you are epsousing is the reason why science is in the dumps.
To take a very simple example, let's take "intelligence." Almost immediately we can start arguing about what intelligence is, how to measure it, and so on. Notably, all the participants won't come to any meaningful conclusion because it's a poorly created human construct.
In contrast, the "hard" sciences like physics often deal with something much more clear cut: can you predict the future? If the starting conditions are X, what are the conditions at some time Y?
Can this be applied to the social sciences? We don't remotely know enough about things like the mind to be able to do this. Hell, even in biology the systems are so complex that we are still at the point of mostly guessing.
It's just not the same. Not by any fault of the people trying to study these extremely complex systems of course. Still, at the end of the day we should be honest with ourselves and recognize the differences.
Just like Newton's laws eh? Newton's laws of motion are Right. They are also inaccurate compared to Einstein's theories of relativity, which must mean Newton's rules are Wrong and Einstein is Right. But wait! There's quantum mechanics which proves that Einstein's work can only be Wrong because there's no way his science could be Right while contradicting quantum mechanics, which is Right.
You have asserted that science (now inexplicably a noun) cannot be Half-Right or Less Reliable so are Newton's laws Right or Wrong? Is Relativility Right or Wrong?
Or perhaps Newton was merely "less precise" - maybe another way of putting it is "less reliable"? - then Einstein.
I think you may be firmly in the "wrong" camp, since you insist so in binary classifications.
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".
Should a physicist be making approximations? Probably not, but a biomedical researcher probably should.
This sound a lot like trolling, but I'll bite for this once.
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. Your theory can't be vague and non-falsifiable. And you have to get a lot more than what you put into your theory. Regardless of how much you want to call it science, that is just pseudoscience.
I personally really don't want to be associated with such "scientists". Which is why I think twice using the word science/scientist and tend to use the word physics/physicists. All thanks to scientists who are able to think out-of-the-box, unlike the narrow-minded stupid physicists who don't know anything but scientific method!
