Created 15 years ago, the subreddit is dedicated to examples of chaotic good actions, which have attracted over 217k members already. The instances cover everything from fighting hate groups in the most inventive ways possible to supporting others through tough times, reviving people’s faith in humanity one post at a time.

Such somewhat altruistic behavior encourages people to believe in the kindness of others; and the majority of them do. A survey of adults in the US revealed that as many as 83% of them believe that humans are inherently good. Another one reported that the number was as high as 81%, adding that nearly half of the surveyed, though, consider themselves “better” than everyone else they know. 

Some of the actions in the pictures shared by ‘Chaotic Good’ could be considered expressions of altruism, the level of which, according to some scholars, might vary depending on the individual’s brain.

Research suggests that people who express strong altruistic behavior have a more active—and sometimes even larger—right amygdala, which is responsible for the way we feel and perceive emotions in others; fear especially. That’s why it’s arguably safe to assume that the level of altruism is tied to people’s neurologically driven ability to perceive and empathize with others’ fears and vulnerabilities.

The research also suggests that altruism is ingrained in live beings at an evolutionary level. It is believed that in its basic form, altruism helped preserve species by members helping each other. 

It pointed out that it can be witnessed not only among people, but in the animal kingdom as well; for example, among worker bees that “choose feeding the hive’s young over reproducing” or ravens that alert others of their species of a food supply they all can share.

When it comes to people, their level of altruistic tendencies often depends on certain factors, such as age and social proximity of the other person, as well as the nature of what is being sacrificed in order to help others.

A 2017 study revealed that people feel less altruistic sentiment to those who are more socially distant; for instance, they might not help a stranger, but they would a relative in a similar situation. It also suggested that individuals tend to feel more health altruistic towards young kids and more wealth altruistic towards adults, showing that altruism can be somewhat situational.

It’s not only adults feeling altruistic towards kids, though; children as little as two years exhibit signs of seeking to help others as well. Studies suggest that toddlers feel greater happiness when sharing treats rather than getting them themselves. In addition to that, they feel more content giving up their resources rather than sharing something at no cost.
