Matt Trueman: “A few years ago, I learned how birds fly in flocks. It’s a complex science. When they murmur, seemingly so completely in sync, starlings are in fact steering themselves independently: each to its own. There’s no leader, no one follows, but the flock falls into line because each bird reacts to those around it. … If one flinches, those next to it follow suit; climb and the whole flock climbs with you. Every individual impulse ripples through the group and it grows as it goes. Audiences are the same.”
