The Psychology of Security

The reality of security is mathematical, based on the probability of different risks and the effectiveness of different countermeasures. One can calculate how secure home is from burglary, based on such factors as the crime rate in the neighborhood one live in and doorlocking habits. One can calculate how likely it is for one to be murdered, either on the streets by a stranger or in home by a family member. Or how likely one is to be the victim of identity theft. Given a large enough set of statistics on criminal acts, it's not even hard; insurance companies do it all the time.
