Q & A

What is the trolley problem?

The trolley problem is an ethical dilemma devised by philosopher Philippa Foot in 1967. It presents a scenario where a runaway trolley is heading towards five workers, and you have the option to divert it onto a second track where it would hit one worker instead, forcing a decision between sacrificing one life to save five.

What philosophical principle does the trolley problem often invoke?

The trolley problem often invokes the principle of utilitarianism, which argues for the morally correct decision being the one that maximizes well-being for the greatest number of people.

According to the script, what percentage of respondents in one survey agreed with flipping the switch to save five workers at the cost of one?

In one survey mentioned in the script, about 90% of respondents agreed that it's okay to flip the switch, letting one worker die to save five.

How does the script describe the variation of the trolley problem involving a man on a bridge?

In the bridge variation of the trolley problem, you are on a bridge with a large man next to you, and the only way to stop the trolley is to push the man onto the tracks, sacrificing his life to save the five workers below.

What percentage of people, according to the script, believe it's okay to push the man onto the tracks in the bridge variation?

In the bridge variation, only about 10% of people believe it's okay to push the man onto the tracks, according to the script.

Why do some people find it difficult to accept the utilitarian view in the bridge variation of the trolley problem?

People find it difficult to accept the utilitarian view in the bridge variation because deliberately causing someone's death feels more personal and wrong, even though it's still the logical choice from a utilitarian perspective.

What does the script suggest about the factors influencing our moral judgment in the trolley problem?

The script suggests that factors such as gender, mood (e.g., watching a comedy clip), and the type of action (e.g., pushing vs. flipping a switch) can influence our moral judgment in the trolley problem.

What does the script indicate about the brain's response to the classic and bridge versions of the trolley problem?

The script indicates that both scenarios activate areas of the brain involved in conscious decision-making and emotional responses, but the emotional response and internal conflict are much stronger in the bridge version.

What criticisms does the script mention about the trolley problem?

The script mentions that some philosophers and psychologists criticize the trolley problem for being unrealistic, arguing that its premise may not be taken seriously by study participants.

🚂 The Trolley Problem: Ethical Dilemma

The Trolley Problem is introduced as a classic ethical dilemma, devised by philosopher Philippa Foot in 1967. It presents a scenario where a trolley is speeding towards five workers, and the observer has the option to divert it onto a track with one worker. This dilemma forces us to weigh the moral code against the best outcome, which in utilitarian terms, is to save the greater number of lives. The dilemma is further complicated by variations that involve pushing a man off a bridge to stop the trolley, which reveals a deeper psychological and ethical conflict between allowing death as collateral and actively causing it. The paragraph explores the philosophical principle of utilitarianism and the emotional responses it elicits, as well as the implications of such moral decisions in modern autonomous systems like driver-less cars and military drones.

Keywords

💡Trolley Problem

The Trolley Problem is a thought experiment in ethics, devised by philosopher Philippa Foot in 1967, which presents a moral dilemma where a person must decide between sacrificing one life to save five. It is central to the video's theme of ethical decision-making. The script uses this problem to illustrate the conflict between utilitarianism and deontological ethics.

💡Ethical Dilemma

An ethical dilemma refers to a situation where a difficult choice must be made between two or more alternatives, both of which may involve making a moral sacrifice. The video uses the Trolley Problem as an example of such a dilemma, emphasizing the complexity of moral decision-making.

💡Utilitarianism

Utilitarianism is an ethical theory that suggests the morally right action is the one that maximizes overall well-being for the greatest number of people.

Highlights

The trolley problem is an ethical dilemma devised by philosopher Philippa Foot in 1967.

It challenges us to decide between sacrificing one person to save five when no good choices are available.

90% of respondents in a survey agreed to flip the switch, reflecting utilitarianism's principle of maximizing well-being for the greatest number.

Utilitarianism argues that the morally correct decision is the one that maximizes happiness for the most people, even at the cost of one life.

A modified version of the trolley problem, where pushing a man to stop the trolley, reveals a different response, with only 10% agreeing to the action.

People's instincts suggest a difference between causing death directly and allowing it as a side effect.

Ethics and psychology intersect in the trolley problem, showing that moral judgments depend on more than logical pros and cons.

Gender and mood influences, such as watching a comedy clip, can affect responses to the trolley problem.

Brain activity studies show that the emotional response and internal conflict processing are stronger in the bridge version of the dilemma.

Pushing someone to their death feels more personal, evoking an emotional aversion to killing, despite it being the logical choice.

Critics argue that 'Trolleyology' lacks real-world applicability due to its unrealistic premise.

Ethical analysis is becoming increasingly important with the advent of autonomous technologies like driver-less cars.

Governments are researching autonomous military drones that may need to make decisions involving civilian casualties.

To program ethics into machines, researchers and philosophers are collaborating on the complex problem of valuing human life and judging the greater good.

Hypothetical dilemmas like the trolley problem have real-world implications, especially with the development of autonomous systems.

Transcripts

Imagine you're watching a runaway trolley barreling down the tracks

straight towards five workers who can't escape.

You happen to be standing next to a switch

that will divert the trolley onto a second track.

Here's the problem.

That track has a worker on it, too, but just one.

What do you do?

Do you sacrifice one person to save five?

This is the trolley problem,

a version of an ethical dilemma that philosopher Philippa Foot devised in 1967.

It's popular because it forces us to think about how to choose

when there are no good choices.

Do we pick the action with the best outcome

or stick to a moral code that prohibits causing someone's death?

In one survey, about 90% of respondents said that it's okay to flip the switch,

letting one worker die to save five,

and other studies, including a virtual reality simulation of the dilemma,

have found similar results.

These judgments are consistent with the philosophical principle of utilitarianism

which argues that the morally correct decision

is the one that maximizes well-being for the greatest number of people.

The five lives outweigh one,

even if achieving that outcome requires condemning someone to death.

But people don't always take the utilitarian view,

which we can see by changing the trolley problem a bit.

This time, you're standing on a bridge over the track

as the runaway trolley approaches.

Now there's no second track,

but there is a very large man on the bridge next to you.

If you push him over, his body will stop the trolley,

saving the five workers,

but he'll die.

To utilitarians, the decision is exactly the same,

lose one life to save five.

But in this case, only about 10% of people

say that it's OK to throw the man onto the tracks.

Our instincts tell us that deliberately causing someone's death

is different than allowing them to die as collateral damage.

It just feels wrong for reasons that are hard to explain.

This intersection between ethics and psychology

is what's so interesting about the trolley problem.

The dilemma in its many variations reveal that what we think is right or wrong

depends on factors other than a logical weighing of the pros and cons.

For example, men are more likely than women

to say it's okay to push the man over the bridge.

So are people who watch a comedy clip before doing the thought experiment.

And in one virtual reality study,

people were more willing to sacrifice men than women.

Researchers have studied the brain activity

of people thinking through the classic and bridge versions.

Both scenarios activate areas of the brain involved in conscious decision-making

and emotional responses.

But in the bridge version, the emotional response is much stronger.

So is activity in an area of the brain

associated with processing internal conflict.

Why the difference?

One explanation is that pushing someone to their death feels more personal,

activating an emotional aversion to killing another person,

but we feel conflicted because we know it's still the logical choice.

"Trolleyology" has been criticized by some philosophers and psychologists.

They argue that it doesn't reveal anything because its premise is so unrealistic

that study participants don't take it seriously.

But new technology is making this kind of ethical analysis

more important than ever.

For example, driver-less cars may have to handle choices

like causing a small accident to prevent a larger one.

Meanwhile, governments are researching autonomous military drones

that could wind up making decisions of whether they'll risk civilian casualties

to attack a high-value target.

If we want these actions to be ethical,

we have to decide in advance how to value human life

and judge the greater good.

So researchers who study autonomous systems

are collaborating with philosophers

to address the complex problem of programming ethics into machines,

which goes to show that even hypothetical dilemmas

can wind up on a collision course with the real world.
