In the wake of many recent mass shootings, gun control has taken center stage in public debate in the United States. Those who advocate much stricter gun control point to the bad effects of the continued availability of so many guns in the U.S. Opponents of gun control often appeal to the right to self-defense to argue for their position. How should a society balance the individual rights of its members to protect themselves with its responsibility to promote public safety, more generally?

Carol is a terminally ill woman on life support, whose health has rapidly declined over the past week. Her children argue about her future loudly, and a nurse must decide whether to kick them out or not. On the one hand, their arguing is clearly disruptive to the other patients and their families as well as to the hospital staff. Yet, on the other hand, what Carol’s children are faced with is understandably extremely difficult and emotional.

The World Wide Fund for Nature estimates that poachers kill 100,000 elephants each year for their tusks. Some countried have chosen to burn their ivory stockpiles to send a message to poachers. However, destroying so much ivory only makes it scarcer, which threatens to increase both its value and the motivation for further poaching.

Some software developers and commentators have claimed that complaints about data violence are overhyped. However, others find this response to be little more than an attempt to avoid responsibility for the way in which their own actions help to reinforce and reproduce biases and injustices. What does it mean for something to be sexist or racist? Can we consider software sexist or racist, even though it doesn’t itself have intentions or attitudes?

A month ago, Jessica heard a rumor that Amit cheated on her with one of her friends. Devastated, she confronted him and he admitted that it was true. Determined to make it work, Jessica stayed. But then, out of nowhere, Amit sat Jessica down and told her that he was ending the relationship. Is there anything morally praiseworthy about someone who attempts to mitigate the harms caused by their future bad behavior, when they are not willing to do what they can to not behave badly in the first place?

A longstanding complaint about gerrymandering is that the politicians in office during the redistricting process frequently engage in drawing maps that help themselves and their political allies retain seats or gain additional power. Some argue that critics underestimate the force of larger cultural and demographic trends in driving politically lopsided districts and thus gerrymandering isn’t a problem. What interests do citizens have in fair electoral maps? Are there any interests that all citizens have in maintaining fair electoral maps?

Some neighborhood kids are crowded around Lisa, age seven, who is easily beating one second-grader after another in chess. Immediately, Randy sees that Lisa is cheating, subtly moving pieces when the others aren’t looking, and making up rules that suit her as the games progress.

Proponents of de-extinction argue that humans have an obligation to bring back species that were driven to extinction by human activities, such as the dodo bird. Opponents of de-extinction point out that de-extinction will draw away resources and attention from other scientific efforts to preserve biodiversity.

In the United States, approximately 40% to 50% of marriages end in divorce. With new scientific interventions, we may be able to reduce this number by increasing or prolonging feelings of love. What, if anything, makes loving relationships (including romantic relationships) valuable or important? How, if at all, would “love drugs” add to or detract from that value or importance?

Think of some of the athletes, musicians, actors, political figures, or businesses you most admire. Chances are, at least some of them have paid companies to generate followers, “likes,” and comments for their social media accounts. Some influencers admit that buying followers is wrong, while others regard it as merely a tool of the trade. Is it wrong to buy followers and likes on social media?

One weekend, when Genevieve was house-sitting for Nico and Tomas, she noticed a notebook in an open drawer in Nico’s desk. She couldn’t resist pulling it out and opening to a random page, though she could tell it was a diary. Is reading someone’s diary without their knowledge morally wrong? Why or why not?

On June 14, 2014, China’s State Council announced a plan to establish a social credit system, which would assign “social credit scores” to citizens based on their behavior. Chinese State Council say being rewarded for good behavior will make citizens want to be better, but critics view this as an invasion of privacy and personal freedom. How can a community balance its interest in encouraging its members to engage in socially desirable behaviors with community members’ interests in individual privacy and liberty?

Given that donated organs have a limited time frame for their viability, the U.S. is divided into 11 geographic areas for liver-donation purposes. A new policy change will work to mitigate this geographic disparity. Is it fair to distribute organs by geographic availability? What should we use as the primary criteria for determining how to distribute livers and other vital organs?

Universities are increasingly accepting private money to fund academic centers, programs, and faculty. Often, this money comes from sources that have clear political agendas. Proponents of private funding in academia argue that as long as the supported research and teaching meet the standards of acceptable scholarship, it doesn’t matter how it is funded.

Ravi and Amaia work as data analysts for a large tech company. Given his dissatisfaction with the job, Ravi has decided to quit and go back to school but asks Amaia not to tell. Has Ravi acted unethically? Was Amaia right to tell Ed of Ravi’s decision to go back to school?
