jzs said:Not at all. Anecdotes were never evidence, and they still aren't. Relating a story about a child is not evidence.
Yes, that's why I said it wasn't evidence.
Although there is an aspect to this that needs to be taken into account. How is it possible to show any non anecdotal evidence of what anyone believes? The only way a normal, non-omniscient mortal can determine what someone believes is to ask them. And the response, given that it is simply what that person relates about their own beliefs - is by some definitions purely anecdotal. Either you believe what people say about their beliefs or you don't. If you don't believe them you can never be satisfied as you set an impossible standard.
I, of course, see no reason why I shouldn't believe some people when they say they held such a belief at some time. It is rather to pointless to argue with someone about whether or not they ever believed a particular thing - unless you believe yourself to be omniscient and therefore capable of independently determining their thought processes.
Therefore the only possible evidence that can be offered is what people claim about their beliefs. My son claims he believed me. Other people claim they held such a belief in the past, for example:

When I was very young my Grandfather told me how the moon was made of Green Cheese. My evil older sister told me how the moon was important to life everywhere, and if it wasn't here we would all die. She also told me everytime I ate cheese from earth, I was taking it away from the moon, and if I ate too much cheese, the world would colapse. She was always mean.
or another unnamed person:

When I was about six, my best friend told me the moon was made of green cheese. I wouldn't eat cheese again for years.
I am far more inclined to believe my own son, and these people above that they once believed the moon was made of green cheese, than I am to believe that you are omniscient. Sorry.
jzs said:Children believe in all sorts of things. Should I include their pet rocks too? They don't have a fully adjusted brain that is capable of understanding how the world works. Adults only please. Got any examples yet?
Irrelevent. And that is simply intellectually dishonest. You are moving the goal posts to avoid responsibility for your claim. Your claim was not limited to adults, it was about all people, ever, in the history of the universe - which clearly includes children. It is your claim I contest, not the strawman you would rather I addressed. You have some examples above which directly address your claim.
Pragmatist said:Excuse me!!??? The "default position" is that we should unconditionally accept that you know the actions and beliefs of all people, ever, in the entire history of the universe?
jzs said:Yes.
Ohmigod. You said it. Don't blame me for the consequences.
jzs said:There is no evidence for anyone, ever, seriously thinking the moon is made out of green cheese. I've offered to be proved wrong. Evidence would do that. Got any?
Yes there is, above I have shown some of the only evidence that is possible for such - you are proved wrong.
jzs said:That's simply ad hominem. Got any evidence? Why not?
No, it's a joke, but there is precious little evidence that you have a sense of humor. Joking aside, I am seriously concerned about your mental health given that you believe yourself to be omniscient...

"They were found in the astrology books I have access to."
That wasn't what I asked for. I asked for evidence in support of your claim which was:
jzs said:"alleged" convenience sample? I'll take a sample from the 'books I have available'. That is a convenience sample.
Do I really need to spell it out for you? Sigh...guess I do.
"books I have available" <> "books I have access to"
For example, at this moment in time, speaking for myself I have about 20,000 books "available" - but I have access to books in a host of bookshops and public libraries, a couple of million of them at a rough guess.
Therefore I take your response as evidence that you are unable to provide evidence in support of your claim - again.
jzs said:He looked at the books he had access to. He didn't randomly sample from a larger population of charts.
He never stated whether or not he randomly chose some books from the larger population of those he had access to. So therefore how do you know what he did? Oh, I forgot, you're omniscient...
jzs said:Let's hear what you have to say about that. I'll wait.
Isn't it obvious? If he had access to an extremely large number of books is it likely that he read every single one of them? And if that is not likely, then isn't it more likely that he simply chose some of them more or less randomly?
jzs said:Irrelevant. He got 7 astrological charts via a convenience sample.
No, very relevant. If you don't know how many books he chose his sample from, or under what conditions, you are in no position to call it a "convenience sample". You merely assume it was a convenience sample - and I'm sorry but I don't believe your claim to be omniscient. I require objective evidence not your assumptions or your improbable claims. So please show evidence in respect of the number of books that Claus had access to, and explain why, out of that population, his specific choices constitute a "convenience sample".
By the way, on a related issue, elsewhere you said that a convenience sample of 7 could never be meaningfully extended to any population - or words to that effect - I disagree. I believe a convenience sample of 7 from a population of 8 would be meaningful. Am I wrong? And if so, why?
What is the population of astrologers who use those charts? You must know it to be able to say the sample is insignificant, mustn't you? Although the point is moot for other reasons explained below.
jzs said:Do you see the way your posts go? You try to cover every possibility, with every possibility being a negative outcome for me. ie. 'find evidence, I doubt you can', 'if you do find the evidence, your interpretation is wrong because of x y and z.' 'But if x y or z happen to be true, then your claim is still insignificant'.
I try to cover every possibility - I try to consider all the angles before commenting - it's called being thorough.
jzs said:You are simply biased and don't let the evidence lead you to a conclusion; you already have your conclusion prior to the evidence.
What evidence? You simply duck most questions, you answer questions with questions, you shift the goalposts, you answer questions that weren't asked, you evade, ignore, twist and turn. And above all you don't provide evidence, you provide speculation, assumption and improbable claims. I have asked you several times for evidence in support of your claim that you can know the actions and beliefs of all people, ever, in the history of the universe. Where is that evidence? Care to point it out to me?
Where is the evidence as to the population of books that Claus chose from? Care to point it out to me?
Where is the evidence as to how Claus chose the books and that it is non-random? Care to point it out to me?
Where is the evidence as to the population of astrologers who use those charts? Care to point it out to me?
Since you don't provide evidence I am entitled to draw a conclusion from the absence of evidence almost every time you start making claims. That conclusion is that you don't have any evidence to back your claims, that your claims are simply based on assumption or erroneous conclusions. Does that make me biased? I guess it does - if one defines "bias" as being influenced by the evidence or lack thereof...
jzs said:Claus says the inference was to the population of astrologers that uses such compatibility charts. Even so, making inferences to any population is not legit going by how he sampled. The evidence for this is found in many introductory stats. books that tell you when you can and cannot infer.
Yeah, he told you that several times - even back when you were posting as "T'ai Chi". So why were you hounding him recently to answer the question he had already answered a long time ago?
But let's address your latest claim. The validity of an inference to a population in respect of some commonly used item (such as these astrological charts) depends very much on the size of that population, the size of the population of charts, and the subset of charts (from the population of charts) that the larger population of people tends to use. Therefore in order to be able to say in general terms whether or not any given sample is significant or not, one needs to know these factors. I don't pretend to have any expertise in statistics, but that much is self-evident, regardless of what any introductory text book has to say on the matter. But, if one of the factors highly constrains the others - for example one infers to a specific sub set who do a particular thing - then, without prejudice one can reasonably state that said inference is valid because it is self-limiting in extent. In fact, one would be hard-pressed to show any way in which it is not valid, e.g.
Claus refers to a specific set of charts. The charts are shown clearly in his article. His inference is to any population of astrologers who use those specific charts. What is wrong with that? Nothing. Any astrologer that bases his/her advice on that set of charts should be statistically in error precisely to the extent that Claus shows. And even you agreed on the specific percentages.
Let me give another example. Let us suppose there is a gun. Every time that gun was fired, it was used to murder someone. Therefore is it reasonable to infer that every person who fired that gun is a murderer? Of course it is. How is any other conclusion possible? It doesn't matter how or why I chose that particular gun. If those are the facts in relation to that particular gun then the inference is valid for that particular gun and the population who used it. Elementary logic, no statistics required.
It makes no difference whether it is a convenience sample or not. It doesn't matter what the sample size is. Your criticisms are invalid. End of story.
jzs said:What exactly is my claim?
Do you have a short term memory problem? One could certainly be forgiven for believing so...
Here you are:
jzs said:On the other hand, it is somehow sincere to put forth that comparison even when no one ever in the history of the universe has seriously put forth the notion of the moon being made from green cheese.
jzs said:No one, ever, has seriously considered the moon to be made of green cheese.
Remember them now?
jzs said:When did I ever state I could "obtain a meaningful sample that is representative of all people, ever, in the history of the universe"? Please show me the exact quote.
You didn't. Nor did I say you did. I offered you that as an option to get yourself out of your apparently absurd claim to omniscience. You could have shown that you inferred the above improbable claims based on a fair sampling. Obviously you didn't. The point is of course moot with your admission above that you consider it reasonable that I should unconditionally accept that you are omniscient.
jzs said:Still waiting for someone who really believes the moon is made from green cheese. The matter of the evidence still eludes you.
No it doesn't. I've given you the only reasonably possible evidence of such above - the personal testimony of some people to that effect. Whether you accept it or not is irrelevant.
