U.S. adults were among those most likely to condemn extramarital affairs as immoral in a study of 25 countries.
A Pew Research Center study found Americans are more likely than people in other countries to question the morality of their fellow citizens.
The report, “In 25-Country Survey, Americans Especially Likely To View Fellow Citizens as Morally Bad,” explores how adults in 25 countries rate the morality of others in their nation. It also examines if people consider different behaviors to be morally wrong including drinking alcohol, gambling, having extramarital affairs, using marijuana, viewing pornography, having abortions, homosexuality, getting divorces, and using contraceptives.
The research was based on data from participants in Argentina, Australia, Brazil, Canada, France, Germany, Greece, Hungary, India, Indonesia, Israel, Italy, Japan, Kenya, Mexico, Netherlands, Nigeria, Poland, South Africa, South Korea, Spain, Sweden, Turkey, the United Kingdom, and the United States.
Surveys conducted outside the U.S. were based on nationally representative surveys of 28,333 adults conducted from Jan. 8 to April 26, 2025. In the U.S., Pew surveyed 3,605 adults who are members of the Center’s American Trends Panel (ATP) from March 24–30, 2025.

The report also includes some findings from a separate ATP survey of 8,937 U.S. adults conducted from May 5–11, 2025. The margin of sampling error for the full sample of 3,605 respondents is plus or minus 1.9 percentage points.
According to the research, 47% of U.S. adults reported Americans have “very good” or “somewhat good” morals and ethics, which was the lowest of all countries. The majority of adults in Canada and Indonesia (92%) said the same of the people in their countries.
Most and least accepted behaviors across the globe
Getting a divorce and the use of contraception were found to be the most widely accepted of the nine behaviors.
Only 12% of adults overall said getting a divorce is morally wrong, and 8% said using contraceptives is. The only countries with a slight majority that believe getting a divorce is morally unacceptable are India with 65% holding this view and Nigeria with 55%.
Of the nine behaviors Pew asked participants about, married people having affairs had the strongest overall disapproval. Across the 25 countries, a median of 77% of adults said married people having affairs is morally unacceptable, with at least half of adults in every country holding this view.
U.S. adults were among those to be most likely to condemn extramarital affairs as immoral. Nine in 10 Americans said having an affair is morally wrong, similar to the share of people in Indonesia and in Turkey (92%) who believe the same.

Adults in Germany (55%) and France (53%) are among the least likely to believe having an affair is morally unacceptable.
Behaviors with least international consensus
The report found that for most behaviors asked about, there is not an international consensus if they are morally acceptable or not.
In the Latin American and African countries surveyed, half or more of adults said they believe abortions are morally unacceptable, but in most European countries, the vast majority of adults view abortions as either morally acceptable or not a moral issue at all. In the U.S., the group was fairly split with 47% reporting it is morally unacceptable to have an abortion.
In the U.S., adults are the most accepting of using marijuana and gambling. Only 23% of Americans said using marijuana is morally unacceptable, and 29% said the same in regard to gambling. In most other countries surveyed, more than 40% of adults said they consider gambling and marijuana use to be morally wrong.
In 10 countries, a majority said gambling is morally wrong, including 89% in Indonesia and 71% in Italy. In Australia, 25% said gambling is morally acceptable, and 43% do not see gambling as a moral issue.
In the U.S., 39% of adults reported homosexuality is morally wrong, which was found to be much more than those who hold the same belief in Germany (5%) or Sweden (5%). In other nations including Indonesia (93%) and Nigeria (96%), the majority reported it is morally wrong.
In regard to drinking alcohol, the majority of adults in Indonesia (83%) reported it is a morally unacceptable act. In contrast, only 7% of adults in Australia and Sweden reported the same. In the U.S., a small share of 16% said it is morally unacceptable.
What factors affect views of behaviors?
According to the report, a number of factors seem to affect how adults view the morality of behaviors including political party, religion, and gender.
Democrats and independents who lean toward the Democratic Party are more likely than Republicans and Republican leaners to rate fellow Americans as morally and ethically bad (60% vs. 46%).
Pew examined citizens’ stances based on religious belief and found those who said religion is very important in their lives were more likely to view the behaviors as morally wrong.
In 13 of the 25 countries surveyed, the research looked specifically at the differences between Protestants and Catholics. The report detailed that Protestants are typically more likely than Catholics in the same country to believe homosexuality is wrong. In the U.S., 59% of Protestants reported homosexuality is morally wrong, while 34% of Catholics did.
There is a large variation between Christians in different countries. The majority of Christians surveyed in Africa, Latin America, and the U.S. said having an abortion is morally wrong, but across Europe, the share of Christians who hold this view ranges from 40% in Spain to 7% in Sweden.
Gender is also a factor in how people view moral behaviors. Women tend to be more likely than men to believe some behaviors are morally unacceptable. In nearly every country surveyed, women were more likely than men to say that viewing pornography is wrong. In contrast, men were more likely than women to report homosexuality is morally unacceptable.
Overall, older adults were more likely than younger adults to report the behaviors are morally unacceptable. This is the case with using marijuana in 19 of the 25 surveyed countries. In Germany, adults ages 40 and older are twice as likely as younger adults to believe marijuana use is morally wrong, with 30% of older adults holding this belief and 15% of younger adults.
