Podcast: Crypto-Gram 15 July 2007: Data Reuse

* Correspondent Inference Theory and Terrorism

People tend to infer the motives -- and also the disposition -- of someone who performs an action based on the effects of his actions, and not on external or situational factors.

Terrorism is more likely to work if:
1) the terrorists attack military targets more often than civilian ones.
2) if they have minimalist goals like evicting a foreign power from their country or winning control of a piece of territory, rather than maximalist objectives like establishing a new political system in the country or annihilating another nation. But even so, terrorism is a pretty ineffective means of influencing policy.

* Risks of Data Reuse

Data reuse: Data collected for one purpose and then used for another.

2 bothersome issues about data reuse:

1) we lose control of our data.
2) error rate
