Three-decades-old risk assessment used decide prison release
Briefly

In Spain, a risk assessment formula developed three decades ago continues to influence prisoner release decisions, despite being based on a limited dataset from the 1990s. Civio highlights the downsides of this method, notably that current scores disproportionately penalize foreign prisoners—more than even attempted escape. An interactive graphic illustrates how various factors impact risk scores, raising ethical concerns about reliance on such an outdated system that inadequately reflects present realities and risks perpetuating discriminatory practices in the criminal justice system.
The formula devised 30 years ago was intended to reduce repeat offenses and guide decisions on temporary prisoner releases, relying on a limited sample from the 1990s.
Despite its original intentions, current applications of the formula raise significant concerns, particularly in how foreign status unduly inflates the risk score compared to other serious offenses.
An interactive graphic further illuminates how the scoring system works, revealing that even variables like attempting to escape can have less impact on the score than foreign status.
Civio emphasizes the troubling implications of using an outdated risk assessment tool, consisting of methods developed from a small, decades-old dataset without consideration for evolving societal contexts.
