The big idea: are we really so polarised? | Dominic Packer and Jay Van Bavel

In many democracies the political chasm seems wider than ever. But emotion, not policies, may be what actually divides us

In 2020, the match-making website OkCupid asked 5 million hopeful daters around the world: Could you date someone who has strong political opinions that are the opposite of yours?" Sixty per cent said no, up from 53% a year before.

Scholars used to worry that societies might not be polarised enough. Without clear differences between political parties, they thought, citizens lack choices, and important issues don't get deeply debated. Now this notion seems rather quaint as countries have fractured along political lines, reflected in everything from dating preferences to where people choose to live.
