Human Nature - Still the Same

In the current debates about the Episcopal Church's upcoming General Convention 2006, some traditionalists are asserting that human nature is still the same as it was in biblical times.  I don't disagree. In fact, one of the main premises of my cautiousness about the Bible is that humans in biblical times were just as prone as we are today to errors such as —

• wishful thinking
• jumping to conclusions
• creative memory
• story distortion

We have no reason to think these human faults didn't affect the scriptural authors and editors as much as anyone. 

(Traditionalists argue otherwise, that the Holy Spirit supposedly protected those authors and editors from error.  But they have never offered much in the way of real-world evidence in support of their claim, choosing instead to rely on ipse-dixit arguments and wishful thinking.  Such evidence as they have offered is not exactly probative; for example, while early Christians martyrs were willing to die for their faith,  so too are present-day Islamist suicide bombers.)
