In the 1980s, computer-guided robots let some factories, like a Yamazaki factory in Kentucky, run with only six human workers. When robots took over factory jobs, should companies have owed something — like paid retraining or help finding new work — to the workers who lost those jobs?
Under what conditions do we owe help or support to people who are harmed by a change that benefits everyone else?
The Judgment Lab asks: What do we think about that? When we work on the Judgment Lab, our ultimate goal is to articulate our own principles and values in a thoughtful and respectful way.
As you learned in the reading, the invention of the transistor in 1947 set off a chain of changes that transformed electronics. What started as a tiny replacement for the bulky vacuum tube eventually led to microprocessors: chips no bigger than a fingernail that could do the work of an entire computer. By the 1980s, those chips were powerful enough to control industrial robots in factories.
The reading describes how manufacturers brought computer-guided robots into factories during the 1980s to handle dangerous tasks like welding and spray-painting. Some factories operated with only a handful of human employees. One example, not named in the reading, was a Yamazaki factory in Kentucky that ran with just six human workers because robots did most of the jobs. The robots took over dangerous jobs — but that also meant that factories needed far fewer people for work that had once taken many.
The Judgment Lab asks you to consider workers whose factory jobs were taken over by robots. The robots benefited companies and their customers, but the people who lost their factory jobs faced real harm. Should companies have owed something to those workers, like paid retraining or help finding new work, because they chose to replace them with machines?
The general question asks about people who are "harmed by a change that benefits everyone else." This means a situation where a new development — like a technology, a policy, or an invention — makes life better for most people (through lower prices, safer products, or greater convenience) but causes real damage to a smaller group (like losing a job or a livelihood). The question is whether the people who gain from the change owe some kind of help or support to the people who lose out, and if so, under what circumstances.
Were companies right to replace workers with robots without owing those workers anything, or should they have been required to help them through retraining or finding new work?
Follow the steps below to complete this Judgment Lab. By the end of the lab, you will have decided whether you think companies should have owed something to workers whose jobs were taken over by robots. You will also articulate and test your principles about under what conditions we owe help or support to people who are harmed by a change that benefits everyone else.
Step one
Generating claims
In the 1980s, computer-guided robots let some factories, like a Yamazaki factory in Kentucky, run with only six human workers. When robots took over factory jobs, should companies have owed something — like paid retraining or help finding new work — to the workers who lost those jobs?
Yes
No
Step two
Articulating principles and values
Under what conditions do we owe help or support to people who are harmed by a change that benefits everyone else?
Always, never, or sometimes?
Principles

Values and beliefs
I think that because I believe that...
Step three
Testing principles on a new case
The GI Bill of 1944
During World War Two, more than sixteen million Americans served in the armed forces. Most of them were young men who left school, farms, and factory jobs to fight. While they were overseas, the country at home changed fast: factories expanded, new industries grew, and workers who stayed behind built up years of experience and seniority. Leaders in Washington worried about what would happen when millions of veterans came home all at once to a job market that had moved on without them.
In June 1944, President Franklin Roosevelt signed a law officially called the Servicemen's Readjustment Act. Almost everyone called it the GI Bill. It paid veterans' tuition and living costs if they went to college or trade school, guaranteed low-interest loans so they could buy houses or start small businesses, and gave them weekly unemployment payments for up to a year while they looked for work. The money came from taxes paid by the whole country, including people who had never served.
The results were enormous. By 1956, around 7.8 million veterans had used the education benefits, and millions more used the loan guarantees to buy homes. Economists later argued that the country got back far more in taxes and productivity than the program cost. But the GI Bill also left people out: Black veterans were often blocked from using the housing loans by segregated banks and neighborhoods, and women who had served received far less attention.
Apply your principle to the new case
According to your general principle, did the United States owe returning World War Two veterans the education, loans, and unemployment pay of the GI Bill? Why or why not?
