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.

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.
