This thread isn't about "putting up or shutting up".
Agreed. This thread is, at least nominally, about "critical thinking in ufology."
Unfortunately, the ufologists posting in the thread have consistently demonstrated a lack of understanding of several basic concepts of critical thinking, and have engaged in a number of blatant logical fallacies.
Perhaps we don't have the same views on what constitutes "anecdotal evidence". Please let me know. We might be talking about the same thing and not realize it.
Well up to this point, it appeared we had been in full agreement about the definition of anecdotal evidence, to wit: "a solely verbally-related account absent of any additional corroborating evidence."
However, I have a feeling that's about to change...
Also, by all means see if you can find something scientific to discuss. I'm open to discussing scientific findings.
This invitation is arrogant and disingenuous. Several of the posters in this thread have repeatedly raised some very basic questions about flaws in your methodology regarding the subject, but you have consistently brushed them off with weaselly allegations that "this thread is about critical thinking, and science is not critical thinking."
Firsthand knowledge is not anecdotal evidence.
OK, I'll concede that this is technically correct. "Firsthand knowledge" alone is definitely not anecdotal, until the person with that knowledge relates it to another; at that point it fits the very definition of anecdotal.
Technically anecdotal eveidence is "secondhand or hearsay". A report from a firsthand witness is not anecdotal evidence.
This is wrong. Hearsay is a subset of anecdotal evidence. To put it plainly, hearsay is anecdotal evidence once-removed, or a story repeated by a third party.
For example: "I saw the defendant pull out a pistol and shoot the cashier three times in the chest," is anecdotal evidence told from the first person point of view by an alleged eyewitness, whereas "My cousin Bill told me he saw the defendant pull out a pistol and shoot the cashier three times in the chest," would be hearsay.
Typically what most people mean, and what I presume you and most other people presume to be anecdotal is a "verbal account", which is in actual fact not anecdotal unless it relays an account. For example, "I heard so and so say they saw a UFO" is anecdotal. The phrase "I saw a UFO", is not anecdotal.
This is wrong. You keep trying to redefine the definitions of words to bolster your argument, and that is a dishonest argument tactic. It's also a logical fallacy called (not surprisingly) "redefinition." Using it one-sidedly as you did to bolster your argument in the middle of a debate already in progress, is also an example of "moving the goalposts."
Also, if you missed it earlier, consider anecdotal medical case reporting:
http://en.wikipedia.org/wiki/Case_report
Medical case reporting is irrelevant to this discussion. Real medical doctors do not use anecdotal evidence as the sole criteria for making a diagnosis. At most, it's used as a jumping-off point for narrowing down the patient's condition to a number of possible ailments already known to exist through scientific process.
Furthermore, modern scientific medicine has a specific methodology for assessing the validity of paranormal claims.
Here's an example:
Reiki is a form of religious-based "spiritual healing" developed by a 20th Century Buddhist monk from Japan. The practice of Reiki involves a trained practitioner meditating or praying to spirits while moving his hands around above the body of the patient. There is no known physical mechanism whereby this form of treatment can possibly work, therefore there's no scientific basis to expect it will have any effect whatsoever on any real, physical ailments.
Yet, Reiki practitioners and some of their patients claim the practice has effectively cured them of physical ailments. These claims constitute anecdotal evidence.
Is it good critical thinking practice to just accept these anecdotes at face value? Of course not. Human beings are highly prone to cognitive biases. They tend to allow their hopes and dreams to cloud their judgment of reality. They sometimes lie and deceive others for any number of reasons, sometimes for no reason at all. They sometimes even imagine things that aren't real.
Because both subjects and researchers are human beings prone to bias, we need to find some method to eliminate that bias and ensure objectivity. Proper critical thinking would entail looking for some objective way to find falsifiable evidence to evaluate these claims.
The accepted practice in medicine for establishing this kind of evidence is the double-blind test, with control and test groups, and neither the subject nor the researcher knows which group is the control and which is the test.
Our first hypothesis: "Reiki is more effective than placebo at curing or diminishing the progression of the illness."
Our second hypothesis: "Reiki is not more effective than placebo at curing or diminishing the progression the illness, but patients report its effectiveness in reducing suffering associated with the illness."
Our null hypothesis: "Reiki is less effective than placebo reducing the illness and diminishing related suffering."
So we set up our study. Our test set consists of a randomized group of patients suffering from a real illness, receiving treatment according to traditional Reiki methodology by a trained and experienced Reiki practitioner. The control set is a randomized group of patients suffering from the same illness, but receiving fake treatment by a professional janitor with no formal knowledge of Reiki practice, who has been instructed to mimic the actions of Reiki practice: slowly moving his hands around above the patient while pretending to concentrate.
The test is designed in such a way that neither the patients nor the researchers can possibly know which patients received the real treatment and which received the fake.
After the tests have been done, we gather our data. First, we ask all the patients how they feel afterward. Then we run a series of medical tests on all the patients to see which, if any, actually exhibited an improvement after the treatment. We plot all the results on a graph, and that would constitute our objective evidence.
So we look at our evidence, and see whether there's conclusive proof that Reiki is more effective than placebo (fake treatment) at curing the ailment or having the more subjective effect of relieving suffering.
This is the methodology by which science is done. It's a methodical process, designed to control as many variables as possible, except the ones we want to test.
Critical thinking acknowledges that the methodology of science represents the very best practices to date for discovering the objective nature of our Universe, thus critical thinking and the practice of science go hand-in-hand.
There. I said it. OK?
You wanna talk critical thinking, you have to accept scientific methods. Otherwise, you're not being critical, and I propose using a different term for your kind of thinking.
Say, "credulous thinking," "pseudoscience," or "woo."
