i can see why you like anecdotes so much.
it was suspected after 1 case and confirmed after 15 more cases were found. it was also already known to exist in semen. and these cases are CONFIRMED cases, i.e., much interviewing and follow-up was done to vet that these are actual cases. but even if the confirmation is wrong, the CDCs mission is to swiftly investigate disease outbreaks. and they make recommendations inline with protecting the public good given the risk. so it's a no brainer to tell people to use condoms even if they are wrong.
of course it's not always ethical to conduct trial. people with terminal illnesses is a common example. but there are lot's of statistically sound studies you can do instead, even if they're not as good as a clinical trial. doesn't change the fact that trials are still the gold standard and anecdotes the worst.
but, as in your earlier zinc example, if condoms had a 1% chance of working, i highly doubt the CDC will encourage their use. would you use a condom with a 1% success rate? how about if i told you we had more anecdotal information that increase the chance to 1.01%? i wouldn't be buying stock in any condom companies just yet.
so, tell us how you get unbiased results with anecdotal data? given you worked as a statistician for years and years you do know that to mathematically show a statistic is unbiased you have to assume that the data used to calculate the statistic come from a random sample (among other things). biased samples lead to biased conclusions, whether you're a Bayesian or a Frequentist (user of classical statistics).
your zika anecdote is not a response to the fact that anecdotes are not random samples, have no control group, are unmasked, etc.. you have yet to respond to this (7th attempt).
Anecdotes, as we are discussing them, are unverified. If they were verified, they would have value as evidence.
But they aren't, so they don't.
Great sideshow you got going here, Jabba. Fine distraction from the utter failure of your Bayesian proof attempt.
Why do you keep asking me to respond to your questions after I've stated that I won't? You can ask 10, 20, 100 times. I don't care. I'm done with you on this subject for the reasons stated.
As I'll explain to you just once, the discussion has been transferred over from another thread where the discussion was more general. It should have been left there, but the moderators, unfortunately stuck it back here.
Here we go again with this nonsense about ‘only anecdotes that have been verified have any value as evidence.’
Where has this ever been established to be a fact and by whom and how?
If you review (just for example) the recordings of any 911 call center anywhere in the world (and there are thousands, if not tens of thousands)…every single one operates EXCLUSIVELY on the basis of the credibility of anecdotal evidence!!!!
…and what of the countless examples in jurisprudence where evidence presented by a witness is EXCLUSIVELY a function of the credibility of the witness. And if you doubt this INDISPUTABLE fact …just go and ask our residence lawyer how often the credibility of a witness is an issue in any kind of trial.
Why?....quite obviously…because the ANECDOTAL EVIDENCE that many witnesses report cannot be verified. Which is the whole POINT of witnesses. If the evidence could be verified without the witness…the witness wouldn’t bloody well be necessary!
IOW...what someone says has value (is evidence) for no other reason than that it is what someone says!!!!
People get convicted for no other reason than a single CREDIBLE witness established that the crime in question was committed by that individual. Exclusively anecdotal evidence in such cases is not just relevant…but relevant enough to send someone to jail!
Slowvehicle,
- I can't remember what I've presented so far, and it would take me awhile to look them (or it?) up, but the book I'm slowly reading (The Self Does Not Die) is only $10 by KIndle, and contains 100 anecdotes that I consider evidence of immateriality...
Argumemnon,
- That's exactly what I did.
Evidence is something that supports the logical inference or deduction of a given conclusion. Assertions with unknown truth values do not do this.
As anecdotes are unverified, they have an unknown truth value. Therefore, they are not evidence.
I could go into a long and pointless tangent about how the police are there as a protective measure and are required to respond to these calls regardless of any supporting evidence that does or does not exist.
I could also repeat the earlier point about the difference between taking the existence of a report as evidence of something happening and assuming that the contents of the report are necessarily an accurate description of what that something is.
I could raise the point that Garrette and JayUtah have already made regarding situations like this having, in fact, quite a lot of surrounding evidence regarding knowledge about the speaker and the context in which the thing is being said.
I could even, if I felt particularly feisty, repeat the point about people behaving irrationally on a consistent basis, even in the context of the police, not changing the fact that they are behaving irrationally.
In fact, I think I'll do all of the above.
Try harder.
And if the witness' claims cannot be corroborated with other evidence, they are thrown out. Because they are anecdotes, and anecdotes have no value as evidence.
You are only making yourself look sillier.

And I notice that you keep avoiding my questions.
Would you consider it methodologically sound, in the testing of a scientific hypothesis, to assume that nobody could or would lie when speaking to you?
How would you eliminate this possibility when conducting a scientific experiment?
How would you ensure that this wasn't the case when conducting a scientific experiment?
So you haven't a clue where any of your claims have been established or by who. Nothing but hand-waving. There now…that was easy.
Since your claim that unverified anecdotes have no truth value is itself an unverified anecdote…
…which still make’s them evidence because they logically infer or deduce a conclusion from nothing more than the call.
How do we know this?...They RESPOND…and the RESPONSE is an explicit reflection of the information contained in the anecdote.
“My house is on fire.” Do your best to identify all this ‘surrounding evidence regarding knowledge about the speaker and the context in which the thing is being said.”
...when you're done...also explain how all this 'surrounding evidence' (which isn't even there) in any way shape or form changes the anecdotal evidentiary legitimacy of "my house is on fire".
Besides the fact that this statement is utterly incoherent…actually…it is utterly incoherent so I have no idea what it means. Are you suggesting that the first response of a 911 operator upon receiving the call “my house is on fire” is to assume the caller is behaving irrationally and that the call can be ignored!
Tell me Loss Leader…in the judicial system…if the testimony of a credible witness cannot be corroborated with other evidence, is that testimony ‘thrown out’ as Nonpareil claims it is?

This question is ridiculous.
Presumably you are asking how I would eliminate the possibility of fraudulent answers.
Quite OBVIOUSLY….that is impossible. Usually anecdotes are collected under an assumption of integrity.
A question is asked…and an honest answer is provided.
I know that must sound like a truly mind-boggling concept. Strangely enough…it seems to work.
There’s a marked difference between “avoiding” and “couldn’t care less.”

You ask people to be honest. It’s an amazing idea. Been around for a little while. Couple thousand years last I checked!
….every heard of it????
Even if people were 100% honest 100% of the time they could still be mistaken or misremembering.

The real distraction are the numerous "skeptics" who haven't a clue what evidence is and how it's used to update beliefs. But this forum has been going downhill for awhile now, so I can't say I'm surprised.

You don't understand what any of those words mean, up to and including "claim".
That is the definition of "unverified", annnnoid. It means we don't know whether or not it is true.
Read before responding.
one word at a timeLL,.
I am saying that evidence is anything that is necessarily true or necessarily false if the hypothesis is true...
