Ok, so debunking is the challenging of claims. Science is the investigation of these claims by evaluation of evidence. To debunk is to begin with a preconceived notion that what you are challenging is bunk.
Not necessarily.
Sure, a defense attorney begins with a preconceived notion that the defendant is innocent, and attempts to debunk the prosecution's case on that basis. But even then, it's the evidence that determines the outcome, not anyone's "notion" going in.
But debunking does not imply or require any preconceived notions. Any time scientists repeat another researcher's experiment (or their own) in an attempt to replicate their findings, there is the possibility that the result will debunk the original findings instead. If that were not the case, repeating an experiment would never be necessary or useful.
That debunking only results from preconceived notions is a common slander on science, scientists, and critical thinking, more usually expressed as "scientists only ever discover what they expect to find," "science is blinded by established paradigms," or simply, "scientists are closed-minded."
Pure opinion. The official explanations lack evidence and yet that doesn't seem to bother you in the least.
I'm waiting on the substantial evidence which supports the official story.
Then the truthers' debunking should be very easy, and very readily accepted by a majority among reporters, scientists, politicians, historians, executives in the affected businesses, and innocent participants in the event itself.
And yet, it is not.
Why do you think that is? I think it's because the official explanations do not lack an overwhelming preponderance of evidence and to conclude otherwise is wishful thinking. But perhaps you have a different explanation to offer.
On this there may be some agreement. Since the first responsibility is to prove the inital claim, Twoofie Truthers are challenging the official story, calling it bunk and attempting to debunk it. So perhaps the labels should be switched since you, TAM, and many others here feel they know the Twoof.
I'm perfectly okay with referring to people by the labels they've chosen for themselves. (And you'll note that I've rarely if ever used the words "twoof" or "twoofers." To me they're just misspellings.)
Those labels are "truthers" and "skeptics" respectively. For the most part skeptics get called "debunkers" primarily by those wishing to disparage them (though as with "twoofer" some have adapted the title out of prideful defiance of that disparagement), in the mistaken belief (which you yourself stated, as quoted above) that debunking is somehow fallacious reasoning.
But basically your point is valid. Skeptics don't actually get to do much debunking because truthers rarely state the claims that they're attempting to support with evidence, which makes the question of whether their evidence is sufficient to support the claims moot. But whenever a testable point is contested, such as whether demolition explosions make noire or whether a flight data recorder can lose data in a crash, the debunkers turn out to be right and the truthers wrong, so they do seem to have a firmer grasp on the truth. Meanwhile as I said, truthers (unwilling to make their own competing claims) want to debunk the official story but fail to do so.
Really? Like Column 79?
[...]
Maybe you don't get an answer to the question because it's somewhat ridiculous if you don't understand that if NIST cannot provide evidence for their hypothesis this changes our understanding of 9/11.
You mean that you do have an answer for the question, "if NIST is wrong about the behavior of Column 79 in the collapse of WTC7, how would that make any difference in our understanding of the events of 9/11?"
If so then by all means, please state it.
