This is a comment on rcronk's post #16 in the moderated thread.
The normal rational reasoning process is:
1. Look at evidence
2. Find most likely and plausible way of interpreting it
3. Draw conclusion
After years of arguing with creationists, people who believe the moon landings were a hoax etc etc it has become clear to me that such people use an entirely different reasoning process:
1. Decide what you want to believe
2. Look at evidence
3. Find way of cherry-picking and interpreting it, no matter how unlikely or implausible, that will enable you to continue to believe (1)
For example whilst most people will
1. Look at the Grand Canyon
2. Interpret it as an example of how landscape gradually changes over immense periods of time
3. Conclude that the world is at least many tens of thousands of years old
a young earth creationist will
1. Decide to believe that the world is 6000 years old
2. Look at the Grand Canyon
3. Explain it away as the result of the Flood
It's not just religious beliefs, any belief in which the believer has invested emotionally is prone to provoking the same faulty reasoning when they are confronted with contradictory evidence.
Here's a non-religious example. Compare and contrast
1. Evidence: My husband beats me
2. Interpretation: men do not beat women they love
3. Conclusion: my husband does not love me
with
1. Belief: my husband loves me
2. Evidence: my husband beats me
3. Interpretation: I must be doing something very wrong if the husband who loves me has to beat me
People who work with battered women can get very frustrated when they continually go back to their abusers; understanding the faulty reasoning process they are using helps to understand such behaviour.
Anyone who uses the normal rational reasoning process to examine the validity of the Book of Mormon cannot avoid the conclusion that it is a clumsy fake, containing assertions that are demonstrably false. But to True Believers this conclusion is literally unthinkable, so they come up with the prime examples of this faulty reasoning process that rcronk links to in his post.
Here's a rather more useful link for rcronk:
