Susanna Hertrich has an art / thesis project to artificially stimulate people's threat perceptions (by giving them goosebumps, or making hairs stand on end) in response to actual threats, as opposed to perceived ones. It's a topic that I'm unnaturally preoccupied with, since the most egregious examples of the disparity between the two seem to intrude on my life every day. My opinions about whether any given threat is real or illusiory seem to differ from almost everyone, but I'm going to stubbornly cling to the idea that everyone else is crazy. Take the entry on 'terrorist attack' as an example (see diagram.) Public reactions to the topic remind me of nothing so much as a stirred-up ants nest, a psychotic, ineffectual frenzy.
