Well, it is better than anonymous sources, isn't it?
That doesn't really have anything to do with the point theprestige made. He's pointing out that you have implicit faith in some sources simply because of who they appear or claim to be, and reject other sources who are similarly qualified, but your rejection is on entirely different grounds. The criteria by which you evaluate testimony seems more closely connected with whether it agrees with what you want to believe than whether the contributors are appropriately qualified or have made salient points.
There are so many different interested parties in this case, of course, one has to explain their role and viewpoint.
And theprestige's point was that you implicitly accept testimony that agrees with you regardless of its critical value, and you implicitly reject testimony that disagrees with you, on a variety of
ad hoc grounds. You simply assume testimony that agrees with you must be objective, well-informed, and accurate. You assume testimony that disagrees with you must be biased and ill-informed.
Pointing this out is to help evaluate opinion from fact.
You have no problem accepting opinion from someone whom you believe to be well-qualified, so long as that opinion coincides with your beliefs. You categorically dismiss equally qualified opinion when it disagrees with you, often with comically acute prejudice. You aren't actually competent to evaluate expert opinion, so you dismiss those who are, and their opinions.
The opinion of someone who was actually there helps indicate what information is valuable from that of someone who knows nothing about the case...
Agreed. Similarly, the opinion of people who actually know the sciences, conventions, skills, and practices of the endeavors in question are more likely to be correct than those who merely state their beliefs as if they were fact, or who simply take on faith what someone else has said without examining the content critically.
...and deciding 'the JAIC must be right because after all they are the establishment'.
Straw man. I don't see any of your critics claiming that the JAIC report must be correct. I certainly don't see any of them claiming further that it's correct because it was produced by the Establishment. As it stands the JAIC simply seems to do a better job of answering all the evidence than any of the competing theories such as disappearing explosives and submarines and wild political conspiracies.
That's not to say a better job cannot be done, which is why I do not oppose a further investigation using new techniques and incorporating additional evidence. But these conspiracy theories just don't fit the evidence, taken as a whole. You seem to say the competing theories must be taken as objective, complete, and truthful. I'm just not seeing how the evidence leads to such a conclusion.
The views of experts on marine collisions and explosions are surely worth more than Fred and Freda Bloggs who get all of their views from the news on tv or the internet.
I am professionally qualified to evaluate the engineering claims made in this thread. So are others. You are not. There are plenty of people in this thread with applicable professional seafaring experience. You are not one of them. You are the one who doesn't belong. You are the one getting their views from the TV or the Internet, and often getting the facts and underlying fundamentals comically wrong. Simply because you mindlessly quote what others have said does not mean that your critics are similarly hobbled and can't make valuable informed contributions to the discussion that are better than yours. It certainly doesn't make your ignorant, biased interpretations of others' work somehow any more worthy of consideration.
People want to hear the experts, not Fred and Freda.
Or Vixens.
