I see what you are saying here and understand now your meaning in the use of inconsistent vs contradictory. It is important to be aware, however, that the issue of being inconsistent is much different with Joseph Smith's accounts than with a witness to an accident. The obvious expectation of a witness to an accident would be to tell everything relevant to the accident. When telling a story of a personal experience the expectation is much different. It is more about what is relevent to the purpose for telling the story. In different settings I will leave many details out of a story that I don't feel are as important as the details I include. I may tell the same story a dozen times and each time this true story would be "inconsistent" per your definition, yet that inconsistency would not be a reason to doubt the truthfulness of the story. I can see two reasons for the difference in how different LDS respond to first leaning of the varying accounts. One is who they learn it from. If they read about it in the Improvement Era article in 1970, I can't imagine anyone having any cognitive dissonance over it. Where the doubt problems come in is where they hear it first from a critic where it is presented as a problem. The second reason is the state of that person's faith and desires toward the church. If the person discovering this information is looking for reasons for doubt, this will work as well as anything else they don't immediately completely understand. I think we would be wrong in assuming that since we don't have a documented account means it was not taught. There is good historical evidence that it was taught and told from the beginning. The most obvious evidence is the fact that you don't find any contemporary critics bringing this up as something suspicious. I have never heard of any leader or even member stating that the idea of their being multiple accounts of the fist vision is from anti sources. I guess it is possible, but I would guess too rare to be worthy of comment. I can imagine, however that if asked if Joseph told contradictory stories of his first vision the answer would often be that that is from anti sources, which would be a very accurate answer. It is all in the way the question is being asked.
