How do networks influence our decision-making?

As the Human Risk podcast approached its 100th episode, I thought I\u2019d invite back two guests whose previous appearances have been amongst the most downloaded. And I\u2019m glad I did. Because what Rory Sutherland and Gerald Ashley delivered, wasn\u2019t worthy of a single episode - it was worthy of two!

So on this, the 99th episode of the podcast, I\u2019m sharing Part I of their conversation. In it, they explore a subject they\u2019ve both written about - networks. We all naturally like to make connections between things - sometimes that can be extremely useful, but it can also lead to flawed decision-making.

As many of my listeners will be familiar with Rory and Gerald, I haven\u2019t included introductions. You can find those, if you need them, on their previous appearances on the show.

Gerald\u2019s first appearance is here: https://www.podpage.com/the-human-risk-podcast/gerald-ashley-on-uncertainty/

Rory first appearance is here: https://www.podpage.com/the-human-risk-podcast/rory-sutherland-on-compliance/

What makes both such fantastic guests, is that they have lots of stories to tell; in doing so, they often make references that might not be as obvious to listeners not based in the UK.

For that reason, I\u2019ve included much more detailed show notes than usual. If you come across something you\u2019re unfamiliar with, then the timestamps below will hopefully help.

When you\u2019ve listened to this, look out for Part II of their discussion, available wherever you found this shortly after the initial release.
