Hearing about these rules got me thinking about what I would do to maximize terror if I were a terrorist with limited resources. I’d start by thinking about what really inspires fear. One thing that scares people is the thought that they could be a victim of an attack. With that in mind, I’d want to do something that everybody thinks might be directed at them, even if the individual probability of harm is very low. Humans tend to overestimate small probabilities, so the fear generated by an act of terrorism is greatly disproportionate to the actual risk.
500+ replies, 1/3 in the "you're a freaking idiot" camp. I don't believe the assumption that terrorists already know this so there's no harm in discussing it- they lack the cultural perspective on what would be effective in hitting our psyche - offering this consultation for free is foolhardy.
