Strange thing happens when you write about something going right. People take notice. They read to the end. They share it with their friends. They write to thank you. Eighteen months ago, the Guardian launched a pilot project to see how readers would respond if we deliberately sought out the good things happening in the world. More than 150 pieces of journalism later - in which we have examined the relative merits of everything from dog turds to ketamine, the blockchain to microhouses, and gardening to exoskeletons - we have proof of concept. Reader numbers for this kind of journalism have proven remarkably robust throughout the project. While audiences have always been riveted by bad news (it serves as both an early warning system and a reassurance about the comfort of their own lives), they are tired of the avalanche of awfulness. They are switching off. If people just shrug at news because they feel there is little they can do, nothing will change. Journalists in the US, Europe and the UK are waking up to this by publishing what is variously described as constructive journalism, solutions journalism or, somewhat misleadingly, positive news. Now the Guardian is deepening its commitment to this type of work. Our new series, The Upside, launched this week with [a] determination to show readers all of humanity, not just the bad bits. As our editor-in-chief, Katharine Viner, promised in a speech ... recently, "we will develop ideas that help improve the world, not just critique it."
