What’s going on when we scroll through our social feeds finding momentary happiness in the mishaps of celebrities or politicians whose views we dislike? Or delight in the stupidity of everyday people on 'epic fail' sites? Aleks Krotoski explores whether our digital habits, alongside increasingly polarised attitudes, have ushered in a new age of schadenfreude... and asks if this is always a bad thing?

Aleks hears from author Tiffany Watt Smith who suggests that, whilst schadenfreude is not a new emotion, online platorms may create the perfect conditions for it to flourish; Dr Lea Boecker suggests schadenfreude may have an important role in boosting self-esteem and encouraging group cohesion; fail video aficionado Olly Browning confesses the particular frisson of schadenfreude he feels when justice is served; whilst researcher Emily Cross shares the results of her recent experiments measuring levels of schadenfreude felt towards robots; and Dr Sa-Kiera Hudson invites us to consider whether schadenfreude is always a passive emotion or whether its addictive qualities might sometimes lead to harmful behaviours towards marginalised groups.
