"Argument from authority" is when you claim someone's else's authority and use it for your argument.
"Joe Shmoe likes this product, therefore is must be good."
No, argument from authority also applies to one claiming to be an expert on the subject matter and thus their opinion should be taken as factually correct.
From Wiki definition:
The argument from authority can take several forms. As a syllogism, the argument has the following basic structure:
A says P about subject matter S.
A should be trusted about subject matter S.
Therefore, P is correct.
Artists says that N-trig sucks.
Artists should be trusted on subject matter related to digital art.
Therefore, Artists are correct to say N-trig sucks.
This is classic argument from authority.
The fact is that people who do something for a living will generally know more about the needs of that job than people who don't.
This is completely false. Again see my musician example regarding music compression or human biology of hearing. Even a person using tools of trade everyday may not know how their tools work. A digital artist may be using their Wacom digitizers everyday, but damn if they know how the actual electronics is calculating the cursor position or the pressure applied is communicated via the driver and API level better than the engineers who made and programmed it, in fact I would bet they won't know anything about it.
Or do you think that there is no knowledge gained from experience?
Only of subject matter of actual relevance. Just like I wouldn't put much trust a musician to tell me about how human ear evolution works or how signal processing works, I also don't automatically put faith in the artists telling me that they can "feel" the difference in 256 levels vs 1024 levels of very small pressure exerted on a tiny pixel because I know humans are actually very much prone to bias and errors and our senses are easily fooled by all sorts of tricks or even emotional state of mind.
Matters which I would automatically have more trust an artist on? Things such as colour coordination, how to draw anatomically correct human prosture, that sort of thing. But hell I would automatically listen to artists tell me about how they can feel the "wrongs" of electronics (I'm an engineer BTW, but then I would be arguing from authority too)
Wait... so it's okay for you to call BS on professional artists, but there's somehow something wrong with artists being skeptical about claims of commercial product?
I don't mind if they are actually skeptical, but that is not what's happening. Go to this forum and look for the thread titled "N-triq over Wacom kills the Pro 3 for me. " Is that someone expressing skepticism? NO. He made the conclusion before having hands-on experience. And there are many of these people in EVERY SINGLE Surface thread all over the internet. We are calling out these people for being unreasonable.
But it's somehow okay to be totally sold on the marketing and not be skeptical of the product.
Again, they are not being skeptical when they flat out declare it DOA simply because it is N-trig.
Should I lump you guys in with other people "all over the internet" too? Are you all one homogenous group?
And what group would we be in?
So, if a few artists take a hard stance, it's suddenly "the artists" or "so called artists" that get called out as a general group instead of specifically calling out individuals?
Good job there...
Again, the few but also extremely vocal ones are giving the reasonable ones a bad image. You can't fault people for thinking artists are being unreasonable when the reasonable ones refuse to speak out and let the vocal ones speak so loudly and so unreasonably about something they haven't even tried by already pronounced DOA.
