I would have said "a combination of A and B" if that were available. It's well documented that some amount of systemic deception has occurred, but I doubt it accounts for the majority of this phenomenon.
I think the bulk of instances are most likely to be observational errors of various sorts.
Look forward to the follow up post.
Yep, I'll need to refine the question and provide some more context.
Now that I'm thinking about it, I would obviously be choosing "A, B, C, and D."
Trying to get the branches right on this decision tree.
