The Trolley Problem in Real Life
Vsauce
34 min, 38 sec
A detailed exploration of the trolley problem conducted in a real-world experiment with a self-driving car scenario.
Summary
- The experiment tests human responses to a real-life version of the trolley problem, where subjects must decide to take action or not in a simulated train track crisis.
- Subjects were prescreened for psychological robustness and unaware of the experiment's true nature, believing they were participating in a focus group for high-speed rail.
- Out of seven participants, only two took decisive action to switch the train track, preferring to save more lives at the expense of few.
- The experiment emphasized the difference between theoretical responses and actual behavior under stress, and the importance of debriefing and ethical considerations in psychological testing.
Chapter 1
The video begins with a sneeze to illustrate the danger of closing your eyes while driving, leading to an introduction of self-driving cars.
- A sneeze while driving at 70 mph results in driving blind for approximately 103 feet.
- The concept of self-driving cars is introduced, highlighting their ability to keep drivers and pedestrians safe.
- A hypothetical ethical dilemma is presented involving an autonomous vehicle needing to choose between hitting multiple people or swerving to hit one person.
Chapter 2
The segment introduces the trolley problem, a famous ethical thought experiment.
- Philosophical thought experiment where a person must choose to divert a runaway train to save five people by killing one or do nothing and let the train kill five.
- Most surveyed people say they would pull the lever to save the greater number of lives.
- The difference between how people say they would act and how they actually might act in real life is discussed.
Chapter 3
The setup for conducting the trolley problem experiment is explained.
- The hypothetical experiment setup involves subjects watching trains on monitors and believing they control a lever that switches tracks.
- Ethical implications of potentially risking psychological harm to participants are considered.
- Consultations with a behavioral neuroscientist and an ethics board are conducted to ensure the experiment's ethical integrity.
Chapter 4
Historical psychological experiments and the development of ethics review boards are discussed.
- Controversial psychological experiments like Stanley Milgram's obedience study showed the need for ethical oversight.
- Ethics review boards were developed to weigh the risks and benefits of psychological research.
- The potential social good of the experiment is weighed against the psychological risk to participants.
Chapter 5
Final preparations for the trolley problem experiment are detailed, including staging and safety precautions.
- An abandoned railroad line and a freight train are used for staging the experiment.
- Actors are hired and filmed safely to create the illusion of imminent danger.
- Subjects are screened using psychological surveys to minimize potential harm.
Chapter 6
The trolley problem experiment is conducted with various subjects, who are unaware of its true nature.
- Subjects are introduced to the train switching station and the operator, who is actually an actor.
- They are shown how to operate the track switching lever, believing it to be a live control system.
- A staged crisis occurs, forcing subjects to decide whether to switch the tracks.
Chapter 7
The reactions and decision-making processes of the subjects during the experiment are analyzed.
- Different subjects exhibit various reactions, ranging from freezing to actively switching the tracks.
- The experiment demonstrates the gap between anticipated and actual behavior in stressful situations.
- Debriefing and counseling are provided to ensure the well-being of the subjects post-experiment.
