From a tweet by Eli Dourado with the note: “Everything you need to know about cyberterrorism in one chart.”
It would be helpful to have a chart like this one for several topics. Terrorism, cyberterrorism, crime, etc.
This is one aspect of what is called “risk assessment.”
Risk assessment would say that a wandering planet crashing into the Earth is a very bad thing, the odds of that happening are very low and the likelihood of an effective response is nil.
Accurate risk assessments could reduce the waste of resources on improbable incidents or those for which there is no effective response.
