Terms like "Gen Z", "Boomer" and "Millennial" are popular, but they have no basis in science. Demographers and social scientists are now pushing back.

Generational labelling, they argue, is akin to Astrology and while politicians, journalists and media influencers find them irresistible, they actually promote pseudo-science, sew social division and can reinforce prejudicial stereotypes.

So why are generational labels so popular?

Pew Research Center's response

It certainly feels like a very shouty world. But have we really reached a new low point in civility? And, if so, where to from here? We examine what civility really entails and how it can help foster cooperation but also lead to the submission of minorities. And did you know that even the design of our urban spaces can shape and limit acts of civility? So, how can we make our cities more sociable?

Rana Sylvatica is an unassuming wood frog with an extraordinary gift. In the depths of winter, it can slow down its metabolism, flood its cells with ice and remain in a state of suspended animation for months. But it's what it might be able to teach us about preserving human organs for transplant that has scientists really excited. Also, the menagerie in an icy test tube — San Diego's Frozen Zoo and the fight to preserve biodiversity.

There’s a growing public sense that the current model of the social contract is broken, due in large part to rising inequality and the pursuit of profit over social progress. The “social contract” defines the relationship between citizens, their government and business. Its modern form emerged after WWII and, in western democracies, was largely structured around the principles of the welfare state. It’s about equity, order and trust. So, does the essence of the social contract still have value? And if so, how can it make fit for purpose in the 21st century?

Sometimes, despite the hype, despite extensive funding, and despite clever and ingenious thinking, good ideas fail. Or at least don’t live up to their initial promise. There are lessons to be learnt and interesting anecdotes to be told.

The global Covid 19 lockdown may seem like an eternity ago, but the threat of another full-scale pandemic has never resided.  Scientists warn that as the Arctic permafrost continues to melt ancient viruses and bacteria are gradually being freed from the ice. The risks are significant, but researchers are working to identify potential threats and better prepare the world for future pandemics. Uppermost in many minds is the need to ensure future global cooperation in the event of another zoonotic outbreak.
