Can you show that people have been "almost always" wrong on every issue?
Yeah, you can. It's not difficult. (see below) Of course, it doesn't matter as this is clearly a trap.
Yes. You failed to enumerate and list every issue
You can point to individual anecodatal points
This is why it's a trap. If the parent can't give a complete run-down from 500 BCE onward, you'll shout some nonsense about anecdotes. Let's see if I'm right.,,
Correct. I don't think it is possible to enumerate every issue, but your claim presumes otherwise.
On gravity, the laws of thermodynamics, on quantum mechanics, on the atom theory of nature, on evolution,
Quantum mechanics is a bit new -- including it in your absurd list is dishonest as it hasn't had time to fail spectacularly like history suggests it will. Gravity: obvious examples are obvious. If you're particularly thick, just google "history of gravity". Atomic theory: dramatically changed several times pre and post Einstein. The atom today is so dramatically different from the atom in, say, 1850 that I'd say the science of the time was "spectacularly wrong". Thermodynamics: phlogiston, caloric theory, need I go on?
Shoot, I took the bait! Did I spring the trap?
Science proceeds by falsification. In the example of gravity - the work of Copernicus / Kepler / Newton disproved the existing Heliocentric view.
Newtons theory was/is an extraordinarily effective theory: it matched observations and produced predictions that came true for the next
three hundred years. Yes, it was superceded by Einsteins work, but in practice Engineers and Scientists use Newtons theory to this day for
almost all work. Hence, no I wouldn't say Newton was "spectacularly wrong", especially given the evidence available.
, but "almost always" and "spectacularly wrong" on every issue is a very strong statement.
It's a strong statement, and you can object to "spectacularly" if you want to split hairs. Of course, that doesn't make the statement any less true. It's also an important part of what makes science work. See, you're operating under this superstitious delusion that science progresses toward "truth" through a process of refinement. It should be obvious to anyone with even a passive understanding of science, or even the history of science, that this simply isn't true, has never been true, and would be a complete disaster if science operated on that assumption!
Because you can (almost) never prove a theory true, it looks dangerously possible to be dismissive of any idea you don't like.
But this isn't the case. Consider anthropogenic climate change (ACC): while our existing theories of climate are provisional, the opposing idea that there is no ACC is wrong. There is no theory that explains the observations without ACC.
Also, "faith" has no place in science.
That depends on what you mean by "faith". Particle physics seemed to get on just fine with faith that the Higgs boson would be "found". While I understand there are some (less than ideal?) Higgs-free models on the ready, it seems that the consensus is that the Higgs will be found and that it would mean a big change for the field if they can't find it.
Ok, by "faith" I mean accepting /believing without evidence. (belief is another dangerous word: I don't think scientists and religious mean the same thing by it, and I try to avoid it). Particle physicists didn't have "faith" it would be found. They provisionally accepted the hypothesis in order to investigate and test it. Holding and testing hypotheses are not faith; the "belief" is provisional and explicitly not accepted yet.
I provisionally accept lots of things, based on the scientific consensus of my colleagues
Why don't I believe for an instant that you're any sort of scientist? Hell, my background is in the social sciences and even I have a better grasp of this than you do! This is pretty thin mix of basic science and popular science here. How can you possibly fail this so spectacularly?!
Contrary evidence trumps consensus, , but in the case of climate change, it isn't there.
You've looked at it all and found that every bit of available data points decisively to AGW? Yeah, you're definitely not a scientist of any sort.
Nope, I've not looked at all the evidence. Vast swathes of phenomenology for example (the changes in species extent / growing seasons, etc due to climate change) I've accepted from my biologist colleagues without examining in any detail.
But others: I have explicitly examined the evidence, and been involved in doing so, for example in precipitation and temperature change in Ireland.
I've read all the reviews I can (eg the IPCC reports) and made a deliberate point of examining all the contrary evidence and papers I can and found them wanting. There was a sufficiently small volume that yes, it is possible to read it all. And over the last decade or so, its just about all been disproven.
In the larger picture: there is no countervailing theory. There is no theory or hypothesis that explains the observations without human-induced climate change. Our theories do predict the evidence, within observational and measurement error to the point that they are, I think, effective theories: that is, you can use them for policy purposes. Yes, I'm painfully aware of the limitations of the theories and models (working on them on a daily basis) and they will be improved. But "spectacularly wrong", as in unfit for use, no.
