Stimulus

Filmmaker: I use hidden cameras when filming documentaries, because people behave differently when they are aware of being filmed. Although my subjects have been told that a camera is present, they remain unaware of its location and act naturally. Hence, my documentaries for example, people speak directly to the camera.

What this question is testing

Principle-Strengthen

Evidence

Hidden cameras mean the subjects do not know where the camera is. They act naturally. Meanwhile, in other documentaries, people talk straight to the camera and clearly know they are being filmed.

Conclusion

Therefore the hidden-camera documentaries are more worthwhile.

Evaluate

The argument says "my subjects act naturally" and concludes "my documentaries are better." But why does natural behavior make a documentary better? Maybe the most worthwhile documentary is one about an important topic where people speak directly to the camera with prepared, thoughtful statements. The argument needs a principle that says natural = worthwhile.

Goal

Find the answer that bridges authentic behavior to documentary quality.

Which one of the following principles, if valid, most helps to justify

Answer choices, explained

  1. Bad Evidence Match2% picked this

    A documentary with no purpose other than authentically depicting the behavior of its human subjects

    This answer says a documentary with no purpose other than authentically depicting human behavior can be "legitimate." Two problems. First, the filmmaker's documentary is not described as having "no purpose other than" depicting behavior -- it might serve additional purposes. Second, the conclusion is about documentaries being "worthwhile," not "legitimate." Legitimacy and worthiness are different evaluative standards; a documentary can be legitimate without being worthwhile, and vice versa. This answer uses the wrong evaluative term and describes a narrower category of documentary than the filmmaker's.

  2. Weaker Evidence Match5% picked this

    A documentary can be authentic only if it does not include any subjects speaking directly

    This answer says a documentary can be authentic only if subjects do not speak directly to the camera. This addresses documentary authenticity, not documentary worthwhileness. Even if we established that the filmmaker's documentary is authentic and others are not, we still would not know that authenticity makes a documentary more worthwhile. The conclusion's key concept -- being "more worthwhile" -- is absent from this answer. Additionally, this answer addresses documentary-level authenticity, while the evidence discusses subject-level behavior (acting naturally). Being authentic as a documentary and having subjects who act naturally are related but distinct concepts.

  3. Out of Scope3% picked this

    Makers of documentaries do not have a moral obligation to reveal to their subjects the location of

    This answer addresses whether filmmakers have a moral obligation to reveal camera locations. The argument is not about the ethics of hidden cameras -- it is about the relative worthwhileness of documentaries. Whether the filmmaker's practice is morally permissible is a separate question from whether it produces better documentaries. This answer defends the filmmaker's method against an ethical critique that the argument never raises. The argument's gap is between natural behavior and documentary worth, not between hidden cameras and moral permissibility.

  4. Correct90% picked this

    The more authentically a documentary depicts its subjects, the more worthwhile

    Why this is right

    This answer states that the more authentically a documentary depicts its subjects, the more worthwhile it is. The filmmaker's evidence establishes that subjects act naturally when filmed with hidden cameras, meaning the documentary depicts them authentically. This principle bridges directly from authentic depiction to worthwhileness: more authentic depiction equals more worthwhile documentary. Since the filmmaker's subjects act more naturally than subjects who speak directly to the camera, the filmmaker's documentaries depict subjects more authentically, and therefore -- by this principle -- are more worthwhile. This is the precise bridge between the evidence (natural behavior / authentic depiction) and the conclusion (more worthwhile).

    Skill tested: Principle-Strengthen · how this choice captures the argument's function is the move to repeat next time.

  5. Out of Scope1% picked this

    Subjects of documentaries should not try to discover the locations of the

    This answer says documentary subjects should not try to discover hidden camera locations. The argument does not discuss what subjects should or should not do regarding camera locations. The argument is about the relative worthwhileness of documentaries based on how naturally subjects behave. Whether subjects should or should not search for cameras is an entirely different issue from whether documentaries featuring natural behavior are more worthwhile. This answer addresses subject behavior regarding camera discovery, not the relationship between natural behavior and documentary quality.
