#small groups

‘Crowd wisdom’ refers to the surprising accuracy that can be attained by averaging judgments from independent individuals. However, independence is unusual; people often discuss and collaborate in groups. When does group interaction improve vs. degrade judgment accuracy relative to averaging the group's initial, independent answers? Two large laboratory studies explored the effects of 969 face-to-face discussions on the judgment accuracy of 211 teams facing a range of numeric estimation problems from geographic distances to historical dates to stock prices. Although participants nearly always expected discussions to make their answers more accurate, the actual effects of group interaction on judgment accuracy were decidedly mixed. Importantly, a novel, group-level measure of collective confidence calibration robustly predicted when discussion helped or hurt accuracy relative to the group's initial independent estimates. 

When groups were collectively calibrated prior to discussion, with more accurate members being more confident in their own judgment and less accurate members less confident, subsequent group interactions were likelier to yield increased accuracy. 

We argue that collective calibration predicts improvement because groups typically listen to their most confident members. 

With all the covid-19 shutdown, I’m wondering if anyone out is looking for a virtual group that is studying scripture. My local church groups are going virtual, and I’m happy to facilitate one for some tumblr folks if anyone is interested. 

Message daily-invites if you’re interested along with what book of the Bible you’d like to look at - OT or NT - doesn’t matter to me, but as a protestant, I have no experience with any of the Catholic Bible only books.

Book Review: Activate - New Approach to Small Groups

I have always been frustrated by my lack of ability to really help all these small groups succeed, even if just by putting a little extra money in their pockets to pay off debt. Since international fans can’t easily stream on Melon or Naver, Spotify is one of the best ways we can support these small groups if we can’t afford to buy their music physically or on iTunes. This isn’t an exhaustive list, so if you want to do your own searches and add to it with reblogs, that would be awesome!
