Even using facts, not biased opinions, vastly different models can arise. If the sampled facts that give rise to the models are random, then the models will tend to be similar. However, if the facts that make up the models are selectively placed in the models there can arise dramatically different models pulled from the same facts. Since all models are simplifications or subsets of all facts in reality they will always be prone to this fact selection bias.
