LessonsAnalogy: Original and New Cases, Common Cause, Co-variation and EliminationQuiz

The positive direction is observed when the shared feature and the judgment are both present.

Imagine a particular electrical circuit where closing the switch lights a bulb. Repeating the procedure provides positive observations. But the result also depends on power, wiring, and a working bulb.

Thus seeing the closed switch and illuminated bulb together reveals an association under specified conditions; it does not on its own establish a complete causal explanation.
