33. Working memory limits
A person can only focus on a few things at a time. Will A attack B? Maybe yes, or maybe no, but even that framing alone leaves out important details, a sort of attention shade. One human or even an organization cannot capture all aspects of world problems and perfectly arrange them by order of their degree of danger and priority. This is why computer models can be helpful, because they process more simultaneous details than a human can. Of course, computer models can fail, and need to augment human reasoning, not replace it.
