In risk assessment, how does time since the last incident typically affect weight?

• A. The longer the time since the incident, the more weight it carries.
• B. The longer the time since the incident, the less weight it carries, with more weight on recent behavior.
• C. Time since incident has no effect on risk assessment.
• D. Time since incident determines eligibility regardless of behavior.

Answer: (B)

The main idea is that risk assessments weigh behavior that happened recently more heavily because it’s more predictive of near-term risk; the influence of past incidents tends to decay over time. As time passes since an incident, its informational value decreases, so it contributes less to the risk estimate while more recent behavior receives greater emphasis. This time-decay approach helps ensure the risk score reflects current risk levels rather than just historical history. If an incident occurred long ago, it matters less; if it happened recently, it matters more. The other options don’t fit because an older incident shouldn’t carry more weight than a recent one, time can inform risk through decay rather than having no effect, and using time to determine eligibility ignores how behavior relates to current risk.
