It temporarily gave people the feeling of being safe - but obviously could not be persevered with. He noted that nobody in the audience was wearing a bulletproof vest - even though that would been a good way of ensuring that they would arrive alive to attend his keynote. But traded off against the inconvenience of wearing such a heavy garment in summer and the lack of fashion sense it would convey, people had chosen not to wear one, he said to peals of laughter. People tended to over-estimate uncommon risks and play down common ones; they also tended to over-estimate involuntary risk and overplay voluntary risks, Schneier said. Most of the time this worked reasonably well. But the human brain was optimised to deal with security threats from an age long past and was not used to modern times and all the accompanying threats. Schneier pointed out that when feeling and reality got out of whack, then fear would influence behaviour. "If I sell you a lock that does not work, pretty soon you will notice. Until you do, you will have that feeling of security," he said. |
