Stimulus

A recent study proves that at least some people possess an independent “sixth sense” that allows them to detect whether someone is watching them. In the study, subjects were seated one at a time in the center of a room facing away from a large window. On average, whether or not they were being watched through the window.

    It's irrelevant whether subjects usually guessed they were being watched or not watched. In either case, their accuracy rate was 60%.

  2. No Impact3% picked this

    Since this is about what happens after the experiment, it has nothing to do with explaining what happened during the experiment.

    A similar result was found when the subjects were watched from another room on

    Why this is right

    This states that similar results occurred when individuals were watched from another room via video monitor. It strengthens the conclusion by providing additional data supporting the sixth sense hypothesis and ruling out alternative explanations based on physical presence clues (e.g., sounds, shadows).

  4. Weakens1% picked this

    The room in which the subjects were seated was

    If the room wasn't soundproof, it leaves space for an alternate explanation, such as participants hearing cues, diminishing the claim that a sixth sense is involved.

  5. No Impact0% picked this

    The subjects were mostly graduate students in psychology from a

    Discussing the origin of the subjects (e.g., where they are from) has no impact on the claim of having a sixth sense, as it doesn't relate to the experimental conditions or results.
