Re: Introducing the cherry picking fallacy
The thread has obviously gone off the rails as people want to discuss my previous thread. What all of these disagreements have in common is faulty critical thinking known variously as "confirmation bias," "group-think," "tribalism" and "cherry-picking."
The different terms are related but used in different settings. "Confirmation bias" is discussed among scientists, "group-think" among sociologists and the fallacy of "cherry-picking" among logicians. But the terms are closely related.
Wikipedia has an interesting article on it Confirmation bias - Wikipedia
Basically, people look at evidence expecting to see confirmation of what they want to see. They tend to completely skip over information that is contrary to the position they hold. This is why it is recognized as very important to scientists not to go into research with pre-conceived ideas.
On a forum such as this, it is common to see group-think at work. You see a post from someone and you can immediately see that you disagree with him but perhaps you don't read closely enough to consider the evidence and logic he presents because you see other people from your "tribe" accusing of logical fallacies and stupidity.
It is important to try to avoid confirmation bias and tribalism. It is a serious flaw in good critical thinking skills.
I can think of another reason why everyone but you on this thread thinks that you're talking crap.
It's because you're talking crap.

Yup, lets say there's guy who wants the Big Bang to support the concept of a creator. He stumble's across this quote:
quote:
Many people do not like the idea that time has a beginning, probably because it smacks of divine intervention.
Through Confirmation Bias, he would think that the author was describing his own reason for disliking the idea, rather than the many people's reason.

Re: Reply to PaulK - #263
What I reject is the idea the singularity could have any period of existence without being in expansion. The singularity is a mathematical concept. Some people have this mistaken notion that the universe could exist in an infinitely dense and infinitely hot state without expanding. It's impossible.
I believe in the singularity but it existed for less than one millionth of a second. It immediately began to expand at the beginning of time.
Okay, yeah... we've got a lot to clear up here. Your conception of the Big Bang, the singularity, and time itself has a lot of improvement to be made. We really need to get another topic going where we can discuss just that. And hopefully we can do it without quoting other people...

I have read the book.
Really? Only in post #242 you wrote:
designtheorist, #242 writes:
I have already read the first chapter of Hawking's book.
That was posted at 8:26 a.m. And yet at 9:57 a.m. you claim to have "read the book".
May I suggest that if you got through it that fast, perhaps you didn't read it very carefully?

Re: Introducing the cherry picking fallacy
The thread has obviously gone off the rails as people want to discuss my previous thread. What all of these disagreements have in common is faulty critical thinking known variously as "confirmation bias," "group-think," "tribalism" and "cherry-picking."
I believe it has been mentioned a few times, but the entire problem with posting quotes from people is that there can be different interpretations of what people mean when they say certain things. Our intrinsic human biases can lead us to believing that experts are in agreement with us when they aren't, on all the important points in question.
Quote mining is of course, a subset of 'cherry-picking'. It is cherry picking select quotes that support a particular interpretation of the opinions of a proposed expert. It also falls under 'confirmation bias': a person finds quotes that agree with his position, and does not seek or discounts claims that call conclusion into question.
Cherry picking is often seen in the EvC debate as creationists like to cherry pick results and try to weave them together to suggest they are right. They will cherry pick dating evidence, quote mine the sources and try to weave a story of doubt over radiometric dating, for example.
It is important to try to avoid confirmation bias and tribalism. It is a serious flaw in good critical thinking skills.
Critical thinking avoids confirmation bias because it is critical and confirmation bias is a suspension of criticism. When you have a belief (such as Eddington was an atheist who converted to a religious view because of the big bang), it is important you seek out information that may contradict this view, before presenting it as any kind of evidence.
Thus, you would confirm the religious views of Eddington (specifically you would seek evidence that he was not an atheist, rather than just looking for evidence he was), when he accepted the big bang and when any supposed conversion is meant to have occurred, and preferably you wouldn't settle until you could find a causal link or evidence that a causal link existed between the acceptance of the theory and the subsequent conversion (so as not to fall foul of post hoc ergo propter hoc).
Another sign of confirmation bias is when people become very emotional when confronted with evidence which is contrary to their position. Emotionalism is recognized as inimical to sound rational thinking.
This emotional reaction is called 'cognitive dissonance'
quote:
Cognitive dissonance is a discomfort caused by holding conflicting ideas simultaneously.
(wiki)
Everybody has experienced it, the true test is in how a person handles the experience. Any belief that you have not been in this position, would be frankly delusional - I'm sure you'd agree.
It would be a suspension of critical thinking to reason like this: 'The Eddington being an atheist claim supports my hypothesis, my hypothesis is right, therefore Eddington was an atheist'. I'm sure you can see, since you have admitted you made a mistake, how you could have run afoul of your own stated standards of reasoning.

He was challenged to read Chapter 1. He responded that he had read Chapter 1. Since Chapter 1 is a subset of The Whole Book it would fallacious to assume that just because he HAD read Chapter 1 that also means he HAS NOT read The Whole Book. Indeed, anybody that has read The Whole Book could truthfully say 'I have already read Chapter 1' when challenged by someone to do so.

Message 236
I think in general you are making a number of commonsense assumptions which just don't apply to the things you are attempting to apply them to.
A lot of modern physics is counter-intuitive. And frankly you evdently don't understand why a lot of your implicit assumptions are rather nonsensical in this context.
I don't know what fallacy that amounts to.....?

It would be a strange way to put it. But let's wait 'til he speaks for himself.

Re: Reply to PaulK - #223
I'm not sure if the website is correct or not.
Then why not do some actual research in an actual library?
Websites are rubbish for research because they rarely have any accademic rigour.

The above ontological example models the zero premise to BB theory. It does so by applying the relative uniformity assumption that the alleged zero event eventually ontologically progressed from the compressed alleged sub-microscopic chaos to bloom/expand into all of the present observable order, more than it models the Biblical record evidence for the existence of Jehovah, the maximal Biblical god designer.
-Attributed to Buzsaw Message 53
Moreover that view is a blatantly anti-relativistic one. I'm rather inclined to think that space being relative to time and time relative to location should make such a naive hankering to pin-point an ultimate origin of anything, an aspiration that is not even wrong.
Well, Larni, let's say I much better know what I don't want to say than how exactly say what I do.

Re: Introducing the cherry picking fallacy
Modulous,
I can agree with much of what you have written.
However, your comment below is too high a standard:
When you have a belief (such as Eddington was an atheist who converted to a religious view because of the big bang), it is important you seek out information that may contradict this view, before presenting it as any kind of evidence.
I do my best to present my case error free. But it is impossible for anyone to avoid all errors. Mistakes are going to happy. Obviously, the right thing to do is correct the error when it is pointed out. This forum is about "Understanding through discussion." I want people to point out my errors, but it is unreasonable to expect me or anyone to never make errors.

He accepts that it does and this apparently causes Hawking to look for another explanation which would not smack of divine intervention.

It's not like the rest of us have access to a Secret Vault Of Facts that is kept from you. When you're wrong so many times, one does come to suspect that if you are not actually a deliberate liar, you are not taking much trouble to tell the truth.
