For instance, when they see their mothers in pain, month-old toddlers show comforting behaviors such as hugging, patting, and sharing toys. As infants develop and become more able to analyze what is going on around them, they even have the ability to recognize when a person in their environment is treating another person badly. At a young age, infants are quickly able to figure out whether the consequence of a behavior is good or bad, suggesting that their genes are involved and that experience and learning are not the only causes of moral development.
By 12 months of age, infants begin to understand the concept of fairness. When these infants witness cookies being shared, they expect an equal number of cookies to be given to all of the people involved. Taken together, evidence from these laboratory studies tells us that children under the age of 2 have a very good understanding of which actions will benefit others.
However, as children get older, the expression of their morality changes. For example, while infants seem to see fairness as equality everyone should get the same number of cookies, for example , teenagers tend to prefer giving more resources to those who do not have any already or to those who worked harder.
Thus, these early tendencies in infancy are considered to be the foundation for, but not the exact same as, adult morality. Our concepts of morality are built from the combination of emotions, motivations, and our increasing level of mental understanding as we develop.
Our understanding of the role of the brain in morality is largely based on the three different methods. The first is the study of people with brain lesions, meaning individuals who have had an area of the brain removed in surgery or have experienced an injury to a certain area in an accident [ 4 ]. Neuroscientists scientists who study the brain and nervous system examine how moral behaviors change in these people. Another way to understand the role the brain plays in morality is to use MRI scanners or electrophysiology EEG to image the brain as it functions.
In these experiments, neuroscientists presented children and adults with moral tasks or activities and looked at which regions of the brain were activated while the participants performed these activities. Finally, chemicals in the brain can also be explored to see if they might play a role in moral behaviors see Box 1.
Several chemicals produced in the brain, called neuromodulators, influence morality. The hormone, oxytocin, though wrongly called the moral molecule, has received a lot of attention and hype.
In humans, oxytocin does increase trust and generosity in some situations but can increase envy and bias in others. What is really interesting from an evolutionary perspective is that this is a very ancient molecule that, across mammalian species, plays a critical role in the mother—child relationship by increasing bonding and reducing fear and anxiety.
Another neuromodulator, serotonin, is involved in social behaviors, particularly aggression, and is manufactured in the brain and the intestines. Serotonin has been shown to influence moral judgment by enhancing the negative feelings we have in response to see others experience harm.
To determine which parts of the brain are involved in moral decisions, neuroscientists designed an experiment in which people have their brains imaged as they are performing tasks related to morality.
For example, they were shown pictures or asked to read stories about situations that would usually be considered right or wrong, such as a story in which someone is hurt for no reason, or they were asked to make a difficult decision, such as whether they would steal a drug at a pharmacy to save the life of a sick child.
These studies show that specific regions of the brain are responsible for morality and moral decision-making Figure 1 ; Box 2. Other studies with children have also taught us about the parts of the brain that play a role in morality. These children were shown videos of cartoon characters either pushing and shoving others bad or comforting and sharing with others good. However, most moral judgments require both a rapid, automatic reaction guided by an emotional response, and a more slower reasoning capacity.
The importance of respecting authority has fallen since the beginning of the 20th century, while judging right and wrong based on loyalty to country and family has steadily risen.
Our analysis, using the Google Books database and published in Plos One , showed distinctive trends in our moral priorities between to How we should understand these changes in moral sensibility is a fascinating problem.
Morality is not rigid or monolithic. Moral Foundations Theory , for instance, puts forward five moral grammars, each with its own set of associated virtues and vices. When standards of purity are violated, the reaction is disgust, and violators are seen as unclean and tarnished.
It abhors those who show disrespect and disobedience. It judges right and wrong using values of equality, impartiality and tolerance, and disdains bias and prejudice. People of different ages, genders, personalities, and political beliefs employ these moralities to different degrees. People on the political right, for instance, are more likely to endorse the moralities of purity, authority and ingroup loyalty.
Those on the left rely more on the morality of harm and fairness. Women tend to endorse harm-based morality more than men. We used these five moral foundations in our analysis. Put simply, our culture, at least as revealed through moral language in the books we read and write, is increasing the emphasis it places on some moral foundations and decreasing its emphasis on others.

Moral psychologists know a lot about how people today vary in their moral thinking, but they have largely ignored how moral thinking has changed historically. The nature of that transformation is a matter of speculation. One narrative suggests our recent history is one of de-moralisation. I may actually be very critical of equality but when we search for words without unpacking the context , it will appear as if my use of equality makes me a proponent of equality.
Frankly, I find it quite meaningless to correlate the amount of words used in a text and the belief systems of a society. Language does not work this way. Such arguments about finding social reality in the use of words in texts are a fatal flaw in understanding texts. For example, scientific texts rarely, if ever, use the word reality but to think that the discourse of science is not about the real would be a serious mistake since they are only about the nature of the real.
Finally, there is another fundamental problem related to language in this exercise. Patterns search for similar words used across time. However, this argument is flawed because of the way meaning changes over time.
Words do not have the same meaning over time. There are countless examples of how the meaning of the same word radically changes over time. Meaning accrues through its uses and contexts. So to conclude anything — especially something as important as moral beliefs of a society — from such exercises is problematic.

Most Typists in this situation took the larger share of the pie, consistent with self-interest. But it wasn't only the Typists' choices that were self-interested.
Participants also rated the morality and fairness of each division rule: equality equal payoffs or equity payoffs proportional to work. These moral judgments, too, were self-interested. Participants assigned to be Typists thought equity was more fair and moral, whereas participants assigned to be Checkers thought equality was more fair and moral.
Moreover, when the researchers measured moral values before and after participants were assigned to roles, people were caught in the act: Their moral values changed in a few minutes to favor the rule that gave them a larger share of the money. DeScioli points out that the finding translates to many situations in which people need to divvy up resources such as family members dividing an estate, business partners dividing profits, citizens deciding how tax dollars will be spent, or nations dividing territory.
In the last experiment, the researchers removed the justification for an unequal division by asking both partners to transcribe one paragraph. And, Typists no longer shifted their moral judgments in the self-interested direction. The researchers conclude that the "Pursuit of self-interest is tempered, however, by the constraints of coordination.
