Why does the source where the reply is taken from matters?
I only see a few ways this works.
The answer is correct. In this case, the source doesn't matter.
The answer is incorrect. In this case, the source doesn't matter, there is a flaw in the entire concept.
The answer's correctness depends upon the source. In this case, we have a deeper problem with the entire meaning of what a fact is.
Personally, I actually go with option three, but I think the deeper discussion needs to happen before we begin to even consider if something like featured snippets is worth doing. The best way for me to sum up on feelings on this is that while facts are absolute, any piece of information is either true or false (at least within the realm of normal human interactions), it is impossible to separate any fact from a human's perception of the fact which will automatically introduce biases.
An example: A few weeks ago I read online that did . (I'll leave out the details because it only detracts from the point.) This is a factual statement, I did read it online, as did many others. But if many people who read it online states they read about it online, it creates a perception of truth to it, when the original post and the original replies were all showing how easy it is to create a false character assassination story. Regardless of how factual the statement is (it is true that I did read it online), my stating of such would still be an attempt to mislead even though I was using 100% factual statements.
I do not see any automatic truth determiner being possible until our society realizes the biased nature of human known facts.
