Enjoying a break in the Spanish sun and some very good books. Carruthers's just published book makes a good argument that philosophical treatments of action theory would benefit from taking better into account cognitive sciences, and, among other things, the role of habits.

The core causal question for criminology is what MOVES people to break rules of the law. What makes a person to see and choose crime as an action alternative as a response to a motivation in a particular circumstance.

PREDICTION is about forecasting (correlation and time ordering). CAUSATION is about establishing if a predictors) actually produces the effect, and EXPLANATION is about understanding how that works (identifying a plausible mechanism/s). Explanation is the prime goal of science.

One fundamental problem of asserting crime causation in terms of social categories such as, for example, sex, age, social class and ethnicity is the huge within-group variation. Typically, most people in any such category do not commit more crimes than people in general.

Dags att skrota brottstriangeln som grundval och ledstjärna för den lokala brottspreventionen och inse att det inte är 'tillfället som gör tjuven' utan snarare att det är ’tjuvar som tar tillfället i akt', năgot som med säkerhet gäller för brott av någon större allvarlighet.

I have described the criminology of place as a criminology without people. The criminology of place would benefit a lot from better considering the role of people (propensities) and the role of their differential reactions to various environmental conditions (incentives).
