What is the effect of adding multiple search objects on conditional POS?

• A. POS increases
• B. POS decreases
• C. No effect on POS
• D. POS becomes unstable

Answer: (C)

The key idea is that conditional POS is about the chance to detect a specific object given that object exists and is being searched. That probability depends on the search effort, coverage, and detection conditions applied to that object, not on how many other objects are present. If you keep the search effort for each object the same and assume independent searches, adding more search objects doesn’t change the chance of finding any particular one.

What does change with more objects is the overall chance of finding at least one target, since more opportunities exist. The question’s scenario assumes fixed per-object search parameters, so the conditional POS for each object remains the same.
