Argumentum ad populum

And the fallacy is appealing to a non-legitimate authority. Appealing legitimate authority is not a fallacy.

You don't prove your claim is true by merely asserting and repeating it.
That would be the logical fallacy and argument by assertion and repetition.

The wikipedia definition is evidence that your definition is not the definition that people have always understood it to mean when they say something is an "appeal to authority".

Even in your quote, it is noted that many believe an appeal to a qualified authority is NOT a fallacy.

You misread what it says. Look very carefully again and take note of the differences between what they say and what you claim.

"Some consider that it is a valid inductive argument if all parties of a discussion agree on the reliability of the authority in the given context,[2][3] while others consider that it is always a fallacy to cite an authority on the debated topic as the primary means of supporting an argument.[4]"


You have only two options according to their definition:
1. It can be valid IF all parties in the debate agree that the authority is something that should be assumed to be true. Therefore it is valid to reference them as a source of truth in the context of that debate only.
2. It's never a valid argument, even if all parties agree, because the inherent problems with appealing to human authority (ie. The possibility of them being in error) don't change just because all parties agree to regard that authority as true.

Your definition isn't there.

There is nothing in their definition about it being valid to appeal to an authority as a source of truth if they meet certain professional qualifications.
The only caveat given for allowing such an action is based on both parties agreeing to regard that person as an authority. There is no mention of any other qualification.

There is also nothing in the definition about one party being forced to accept that a person is an authority for determining truth simply because the other party has decided that authority meets their definition of being qualified to become something they can appeal to in order to prove what is true.


I note that you did not comment on their being multiple versions of logic.

As I already said; There is no need for me to get lost in the weeds of irrelevant arguments when I can simply take you back to the definition of "appeal to authority" in order to prove your original claim is wrong.

It could certainly be an interesting topic to debate on it's own (the nature of logic) - but that is something you should go start it's own thread for if you want to debate that. Because it has no relevance to resolving the issue actually being debated here. So to engage in it here would be a red herring distraction unless you could demonstrate some logical need why it must be addressed.

I find it interesting that to bolster your argument, you use Wikipedia as an authority.

You are misrepresenting what I have said and don't understand what I actually argued.

I don't claim wikipedia proves the definition is true because wikipedia is the determiner of what is true. Because that would imply that wikipedia can't be refuted. Which I never claimed.

I'm not saying that wikipedia's conclusion is beyond disputing. So I'm not making an appeal to authority.
You could try to dispute what wikipedia says - but you'd need to provide counter evidence to back up your counter claims.

I cited the definition on wikipedia as evidence for my claim about what the commonly accepted definition of appeal to authority is.
Dictionaries and encylopedias don't create definitions, usually - they merely explain how people are using terms.

I could cite innumerable other similar websites as evidence to my claim that this is, in fact, how people have defined the usage of that term because we see that definition reflected everywhere. Which we wouldn't expect to happen unless it was an accurate reflection of how people were using the term. If there was dispute about what the definition of the term was then you'd logically expect to find evidence of that dispute sown all throughout dictionaries and encylopedias on a wide scale. But you don't. So you have no reason to conclude such a thing has happened.

You, in turn, could provide evidence as a counter argument to that conclusion - if you could find it.

But merely giving us your own personal definition of what you want that term to be defined as doesn't constitute evidence that it represents what has always commonly been held to be the definition of that term.

Dear nPeace

Scientific consensus it not about scientists agreeing with each other’s opinions.

Scientific consensus
means that the research and experiments carried out regarding x y z, confirm the same results and thereby strengthen the likelihood that there’s something to the hypothesis presented.

Dear Hermit
I am sorry, but what you are saying is incorrect.
If you believe it is correct, please provide a written consensus on your statement being true, so that I can look at it.

Confirmation of something, never carries disagreement among the experts in that field.
If something is confirmed, it means the evidence alone bears that out so plainly that everyone in the field of study sees that evidence for what it is.
Do you disagree? Then please, I want to hear your reasons.

An example is light. There is no scientist that debates whether there is a color spectrum of light.
Now that you made that point though, I have wondered this, and I don't believe I heard anyone address it. Perhaps I can hear your 'voice' on it.
When something is "confirmed", and later overturned, and thrown out, what was it before, and is the current "confirmation" truly confirmed?

Are you of the opinion that this statement in the Wiki article is incorrect, and needs to be corrected, or perhaps refined?
Scientific consensus is the collective judgment, position, and opinion of the community of scientists in a particular field of study.

Thank you.

Yes, you cited information. Why did you cite information from Wikipedia? Was it because you thought Wikipedia was an authoritative source? Yes, you did. You were making an argumentum ab auctoritate.




BTW, you also sneakily only quoted parts of the article that agreed with your position. You omitted those parts that disagreed with your position.

Once again, I wasn't disputing your position. @polymath did that quite well.

My argument was that you, while arguing that using authoritative sources was fallacious, used a source that you believe to be authoritative.

By your standards, anyone using any authoritative source to support their argument is guilty of argumentum ab auctoritate. That definitely includes you.

You ask for my “reasons” (?) but the definition of a scientific consensus is not “mine” I’m afraid and its “reasons” (whatever you mean by that …the reasons for why the term means what is does…?) are nothing to do with me.

Regarding Wikipedia or wiki-anything really; personally, I don’t use them and don’t think I’d recommend that you do either, unless they define scientific consensus as accumulated confirming results of a scientifically tested and retested hypothesis.

You are misusing that term. I did not commit the logical fallacy of moving the goalposts.

You have given no logical reasons why we should conclude anything I did falls under the fallacy of "moving the goalposts".

Which makes you guilty of the fallacy of argument by assertion.

Merely asserting that I committed a fallacy doesn't make it true just because you assert I did.
You need to prove your claim is true by giving logical reasons why anything I said qualifies as a fallacy.

I wasn't talking about refutation.

...

I wasn't talking disputing what the Wikipedia article says.

What you were or weren't taking about is not relevant to refuting any of the points I made.

Because I was making reference to what I was talking about.
Ie. I was pointing out why my citation of wikipedia doesn't constitute the definition of an appeal to authority fallacy.

You haven't even attempted to refute the reasons I gave you. So my conclusion stands as logically proven.

Once again, I wasn't disputing your position. @polymath did that quite well.

You have an odd definition of "well", then.
I refuted his attempt to dispute my position.
As of yet he has no response, and you have offered no counter argument against what I said with regards to that.

So you would be engaging in the logical fallacy of argument by assertion.
You don't prove he disputed my position well merely by asserting he did. You need reasons and evidence to show why you think he did.


BTW, you also sneakily only quoted parts of the article that agreed with your position. You omitted those parts that disagreed with your position.
Logical fallacy, argument by assertion.
Merely asserting that the article disagrees with my conclusion doesn't make it so just because you assert it is so.

You would need to prove why you think your claim could be true by quoting anything from the article and then giving logical reasons why you think it disagrees with what I have concluded is true.


Yes, you cited information. Why did you cite information from Wikipedia? Was it because you thought Wikipedia was an authoritative source? Yes, you did. You were making an argumentum ab auctoritate.

...

My argument was that you, while arguing that using authoritative sources was fallacious, used a source that you believe to be authoritative.

By your standards, anyone using any authoritative source to support their argument is guilty of argumentum ab auctoritate. That definitely includes you.


I can sum up why you are wrong succinctly like this:
I am making an argument from common use and using wikipedia as merely one piece of evidence for common use.
I am not making an argument from authority and appealing to wikipedia as the authority.

There's a very clear distinction you're not recognizing there.

I am saying that common use of a word is the way in which the definition of words is determined. Wikipedia just becomes one piece of evidence out of many potential pieces of evidence that demonstrate we have reason to believe this represents the common use and understanding of that word. I could just as easily cite any other website that would give a similar answer and my argument is exactly the same. Which disproves your claim that you think I am making wikipedia some kind of authority on the matter.

Citing wikipedia's definition would only become an appeal to authority in this case if I tried to claim that wikipedia's definition must be regarded as the right one just because it's wikipedia. But I don't make that argument nor do I need to in order to prove my conclusion is true about the definition of appeal to authority.

Therefore, if you want to dispute my conclusion about what the common use and meaning of a term is, you are capable of trying to providing counter evidence such as other websites that say something different.

Likewise, I could respond by citing even more websites that agree with wikipedia's definition to establish that my definition has more common acceptance than yours.

So you see there is nothing special about wikipedia to my argument. I am not appealing to them as the final authority on the matter that settles the debate just because wikipedia said it.


You don't think definitions are defined by common use and meaning? I can logically show otherwise:

First off: You can't accuse me of committing a fallacy of appeal to authority unless you can first establish what a fallacy of appeal to authority is.

So first need to establish what the definition is.

How are you going to do that?

Well, how do you establish the definition of any word or concept?
You look at how it is commonly used.

Why do we do that? Because that's the only way any definition for anything is determined: Common agreement amongst the users of a language about what a term means.
There is no other way by which definitions are determined or can be determined.
Because commonly agreed upon use is a required feature of something before it can by definition be a word in a language.
Otherwise it ceases to be language because by definition language must enable the communication of a concept from one person to another by representing a concept with an abstract symbol/sound/etc.

I am going to preempt what you will try to argue here. You may try to argue that this sounds like an appeal to popularity.
But that is a misapplication and fallacious use of the concept. I will explain why:

We can agree that it is wrong to assert it is true that the earth is flat just because the majority of people believe it is. That would be the definition of an appeal to popularity.

But what if I asked you to prove what the majority of people's favorite color is?

You cannot, by definition, establish the truth of this claim without taking a poll of people to determine what the popularity of the colors are.

Are you making an appeal to popularity in this case? No, of course not, because the very question involves asking a question that concerns the issue of what is popular.

It would, therefore, be logically contradictory to claim we can't establish what the popularity of something is because citing what the popularity of something is a fallacious act.

In light of that, how then do we separate the difference between the two scenarios? It's simple.

The former example involves appealing to popularity when popularity is not actually relevant to the issue in question. That is what makes it fallacious - irrelevance. Because the features of the earth can only be established using observation and math, and the logic applied to that. People's opinions about the shape of the earth are not directly relevant to the process of determining what the shape of the earth actually is.

That is not the case with the later example. In fact, not only can we say that finding the popularity of a color is relevant to the issue of establishing which color is most popular but we can say it is vitally necessary to answer the question - because there is, in fact, no other way the answer to the question could be established other than to do that. So it is then logically impossible to even try to accuse the question of being irrelevant to the issue.

What does that have to do with finding the definitions of words in a language you ask?
It is the same principle of necessity. Because language, by definition, only works based on what the collectively agreed upon meanings of words are. If there is no agreement then it's not language because it can't be used to communicate - which is the definition of what makes it a language.

Therefore, the only way you can answer the question of what a definition of a word is is by surveying or studying the users of a language to ascertain what a given word means to them.

So that process cannot be called a fallacy of appeal to popularity because it is not only relevant to the question being asked but it's actually intrinsically necessary to do in order to answer the question of what the definition of a word is. So you could never be accused of appealing to an irrelevant fact by engaging in that process of trying to survey what people think the definition of a word is in order to figure out what the common agreed upon definition must be - because that is by definition the only way you could answer the question of what the meaning of a word is.

Having established that, how would one logically go about gathering evidence of what the common meaning of a word is?

There may be many ways, but one easy way would be by surveying a collection of website articles, dictionaries, and encyclopedias online to see if they all agree on what the definition of the word is.

If they are all in agreement then that is conclusive evidence in favor of that being the commonly used definition of that word. And if there is no evidence to the contrary then we have no reason to believe the contrary is true.

Logically, if there were significant disagreement out there about what the proper definition of a term is then we would expect to see that reflected in the literature people generate about it's definition.
If we don't see evidence of that then we have no reason to conclude the people collectively do have any significant level of disagreement about what a word is suppose to mean.

Thanks.
A general agreement of opinion. That is the definition.
Do you think that agrees with how you defined it?
It's not very meaty, as to convey so much of what you expressed.
To me, it ...at least that very very brief 'definition' agrees with the Wiki article, which was more specific, and explanatory, imo.
"the collective judgment, position, and opinion of the community of scientists in a particular field of study."

It adds, "but the scientific method steers us away from this [a general agreement of opinion] to an objective framework.

In other words, the way it should be, but is not... in some cases, according to Michael Crichton.
"...the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

There is no such thing as consensus science. If it's consensus, it isn't science. If it's science, it isn't consensus. Period.

No my friend. That’s the definition of “consensus”, not of scientific consensus.

This will be my last attempt to shortly try to explain what is meant by scientific consensus to you, but please bear in mind: at the end of the day, if you do not wish to understand something, I guarantee you, you won’t - and that is no fault of the scientific community; it is your own.

Scientists will form different hypothesis for what may be causing or contributing to a specific tendency that they’ve observed in research. Based on their hypothesis, different variables to test will be chosen and the researchers will analyse and clarify how it impacted on their study.
This whole process (choice of topic and data, observed tendencies and hypothesis, choice of variables, tests, analysis, results and conclusions) is documented in a very organised fashion, as to form a “recipe” for other researchers to follow and when using that “recipe” in enough different studies, leads to the same results enough times, this is called scientific consensus.

Boy oh boy, you must think you are really good at trying to duck, dodge and twist.

Logical fallacies, argument by assertion and ad hominem.

Merely asserting that anything I have said or done constitutes "dodging or twisting" doesn't make your claim true just because you assert it is true.
You are required to quote any specific thing I have said, or explain any specific thing I have done, and give specific reasons why you think that constitutes "dodging or twisting", in order to prove why your claim would supposedly be true.

You won't be able to do that because it never actually happened.

Which also makes you guilty of the ad hominem fallacy. Because you are unable to offer a valid counter argument to my arguments, you can only resort to attacking character by accusations of trying to engage in behavior that involves dodging or twisting.

I never said you were guilty of the 'fallacy of "moving the goalposts"'. There is no such thing as the 'fallacy of "moving the goalposts"'.

Yes, there is:
Moving the Goalposts

You also are still guilty of the fallacy of argument by assertion regardless of whether or not you tried to accuse me of a logical fallacy of "moving the goalposts" or if you meant something else by accusing me of "moving the goalposts".

Either way, the burden of proof is still on you to explain what exactly you mean by that and then to provide any evidence or logical arguments to demonstrate why anything I said or did would supposedly fall under what you claim happened.

You won't be able to demonstrate your accusations have any validity to them because the fact is I have done no such thing.

Logical fallacies, argument by repetition and failure of the burden of rejoinder.

Given that I provided arguments against your claims, and you have provided no counter arguments to them, merely repeating your original claims constitutes the fallacy of argument by repetition.

Your refuted arguments don't stop being refuted just because you repeat them.

It is also a failure of the burden of rejoinder on your part. When someone presents an argument against your claim you have the burden of rejoinder to present a counter argument if you want to claim their conclusion is false. Otherwise you concede the debate by failing to meet your logical burden of rejoinder.

No need to try to educate me... again.
I did not and do not have a problem understanding what scientific consensus is.
I had a problem with the way you tried to define it, which was incorrect, but maybe you will not admit that, and I will not try to make you admit it.
As humans, the majority of us tend to have difficulty doing so at times.

I hope you keep in mind that during this conversation, you did not answer my questions.
I'm sure friends communicate, and answer questions, don't they. Perhaps you were trying to keep things the way you like them though. :)
Take care.

Edit:
@Hermit Philosopher on correction, the wiki definition was not defining the general term consensus. They are different.

In my years of professional experience, groups I have worked in and led have reached "scientific consensus" on a number of issues, and they almost always fell into one of two categories: 1) solid and universal agreement on a conclusion/answer/position, or 2) general agreement on a conclusion/answer/position.

#1 was reached when we had lots of valid data that all pointed to the same thing, had no anomalous data, and there were no valid alternatives.

#2 was reached when the data was less certain or was more sparse, there were notable anomalies or outliers, some colleagues held to alternatives, or more often....we all agreed on the bigger picture but still had disagreements on details.

Examples of #1 included things like what time of year a species bred or the location where they did so; the types of food the species ate; the type of habitats they frequent; and yes...their evolutionary relatedness to other taxa.

Examples of #2 included things like what factors led to the species' decline; what actions are necessary to recover the species; how the species behaved prior to human settlement.

So my point is, "scientific consensus" in my experience simply means that a group of relevant (and that's key) scientists in a field generally agree on something. That "something" can be a big-picture question, or it can be a smaller detail, but when we say "we have consensus" all we mean is that we all agree.

Without this consensus it would be impossible to move forward and make progress on some issues. If we never made an effort to take stock, see where we're all at, and memorialize our consensus, we'd just go in endless loops, constantly revisiting things we should have settled long ago.

I hope that helps @nPeace

That's all Wikipedia is saying. :shrug: How does that help? What's wrong with science that does not have to be agreed on?
For example, I mix two chemicals and a poisonous gas kills all in the room. Do we need a consensus on what we just saw? That's all Michael is saying.
Why does science need the collective judgment, position, and opinion of the community of scientists?
