Why do Christians become Christians?

[Pat Mustard]

I don't have a very good memory.   And perhaps this makes me more attune and able to recognize what I do remember and do not. What is fuzzy, and what is clear.  I also think that it attributes to making me better in my occupation as a troubleshooter of machine controls, because I don't follow a memorized script, but figure it out each time.  However I don't think that I have ever simply inserted an entire story into memory, as you are attempting to describe.  So, I cant relate.  

If this is more common than I thought in others though, perhaps it explains a lot of what I see here.

Confirmation bias doesn't make your memory better roadrunner, it makes it worse. And that is exactly what you describe here to "help" improve your memory, taking the bits you are prejudiced into feeling are right as true and discarding the ones that conflict your worldview. We "remember" episodes which agree with our worldview much better and with more frequency than we remember episodes which conflicts with it, and from you post you've fallen right into that trap.

Oh and if you've never inserted a whole false memory into your life, then you are abolutely unique in human history and should submit yourself for testing. However I'm going to say that this statement is another case of you fooling yourself due to a lack of understanding of your brain's fallibility.
