How do networks influence our decision-making?

As the Human Risk podcast approached its 100th episode, I thought I’d invite back two guests whose previous appearances have been amongst the most downloaded. And I’m glad I did. Because what Rory Sutherland and Gerald Ashley delivered, wasn’t worthy of a single episode - it was worthy of two!

So on this, the 99th episode of the podcast, I’m sharing Part I of their conversation. In it, they explore a subject they’ve 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’t included introductions. You can find those, if you need them, on their previous appearances on the show.

Gerald’s 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’ve included much more detailed show notes than usual. If you come across something you’re unfamiliar with, then the timestamps below will hopefully help.

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