The survey, called "Indicators of Mobilization to Violence," assigns points based on factors like religious observance, travel history, financial transactions, and physical appearance.

A copy of the survey in a classified FBI document was obtained by The Intercept.

The survey itself consists of 48 questions that agents are supposed to answer about terror suspects as part of an investigation. The document also includes a set of frequently asked questions about the scoring system aimed at agents working counterterrorism investigations.

According to the document, the program was rolled out in the fall of 2015.

Many of the questions in the survey have obvious relevance to whether someone is plotting a violent act, such as whether the person has access to weapons, has trained or fought overseas, or has tried to acquire bomb-making materials.
