This series focuses on the foundations of risk assessment—what risk scores represent, how they are constructed, and how they should (and should not) be interpreted.
Before getting into tools, applications, or policy decisions, the goal here is to establish a clear understanding of the core concepts that everything else depends on.
An introduction to a basic but often overlooked issue: not all risk scores mean the same thing, even when they appear similar.
What risk scores actually mean—and how to interpret them in practice.
How risk assessment tools are constructed.
What common metrics like AUC measure—and what they can obscure.
How risk assessment tools are used in real decision contexts, including pretrial and corrections.
