Why Do We Do That?

Are you drawn to the endless news cycle? Do you keep going back for more? Do you feel a strange compulsion to absorb negative news that is weirdly soothing but makes you more stressed? These are signs you may be doomscrolling. But fear not, you’re not the only one. Stuart Soroka is a professor at UCLA who’s been looking at our draw towards negative information and found that people all over the world do it, regardless of culture. In 2020, our year of misery, the Oxford English Dictionary added doomscrolling and named it a word of the year. With the help of Stuart and Radio and TV presenter Clara Amfo, Ella gets to the bottom of whether we humans really are more biased towards negative information, and what we can do to resist it.

It’s a familiar problem with any shared household - there’s always someone who doesn’t do their fair share. Studies have shown that when people with different thresholds live together, the person with the lower tolerance for mess cleans up more, quickly leading to resentment and conflict. So why do some people clean up more than others? What needs to happen for everyone to pull their weight? Evolutionary science has some answers. Ella Al-Shamahi speaks to Dr Nichola Raihani, Professor of Evolution and Behaviour from University College London, to find out about free riders, cheaters and public goods, and how evolutionary scientists view cooperation challenges. Great British Bake Off star Michael Chakraverty shares his own anecdotes of untidy flatmates and failed attempts to enhance cooperation.

Joined by Journalist and BBC Radio 1 presenter Katie Thistleton, and psychologist Professor Richard Russell, Ella discovers fascinating research on how make-up can change the way we perceive faces and ponders on a slightly strange theory about make-up and orgasm.

You might think sitting is a recent technological advancement, but both squat and sit-down toilets have been around for millennia. Today Westerners have embraced the sit-down toilet, whereas billions in Asia, the Middle East, Africa, and even parts of Europe use toilets that are designed specifically for squatting. But which is better for us - sitting or squatting? Ella Al-Shamahi speaks to gastroenterologist Dr Rohan Modi who has been investigating the best way to do your business, and gets personal with comedian Eshaan Akba.
