The study suggests shining a light on the best of human behaviour helps alleviates anguish caused by reports on tragedies.
The cross-continental investigation shows that balanced reporting has a positive impact on society and mental well-being.
Dr Kathryn Buchanan, from the Department of Psychology, led the study and is calling for journalistic reform.
鈥淲ith 1 in 3 people limiting or avoiding news coverage due to its disheartening content, restoring balance to the news with some kindness-focused news stories may offer the hope and mood boost people need, to continue engaging with all that鈥檚 happening in the world,鈥 said Dr Buchanan
In total 1,806 people in America and Britain were studied and shown real reports and footage from major disasters and crime stories.
They were also shown stories of kind acts 鈥 like a nine-year-old using her birthday money to buy food for the homeless 鈥 and funny items, such as an American tourist locked in a British bookstore being rescued after tweeting for help.
It was discovered those shown balanced bulletins enjoyed better moods, societal beliefs, and willingness to act for the benefit of society.
One of the participants said: 鈥淚 felt inspired to do better as a person and human being.鈥
In addition, it was discovered funny tales were not as effective in alleviating the aversive effects of exposure to negative news, leading the researchers to conclude that 鈥渢here is something uniquely powerful and restorative about seeing others鈥 kindness that is not simply attributable to it triggering pleasant feelings鈥
Dr Buchanan鈥檚 paper - Buffering the effects of bad news: Exposure to others鈥 kindness alleviates the aversive effects of viewing others鈥 acts of immorality - was published in PLOS-One.
Dr Buchanan said: 鈥淣ews stories featuring the best of humanity take the sting out of items exploring the worst of humanity.
鈥淭his allows people to maintain a core belief that is crucial for good mental health: that the world and the people in it are fundamentally good.鈥
