How can we bridge the widening ideological chasm in modern democracies without resorting to echo chambers?

I'm increasingly concerned by the polarization I see in political discussions, both online and offline. It feels like everyone is retreating into their own ideological bubbles, and constructive dialogue is becoming impossible. What practical strategies or approaches have you seen work to foster genuine understanding and compromise across deeply entrenched political divides? I'm really looking for actionable ideas beyond just 'be nice'.
