Recent Paper Decent Puzzle is hosted by Dan Riskin, and produced by Meagan Perry. It’s a podcast with two parts: First, Dan breaks down a recent scientific journal article for the curious non-expert. Then Dan presents a fun puzzle.
On average, how many rolls does it take to roll a six?
Evan Brock has cracked the case. His solution is here. Thanks, Evan!
Seeing poor people makes subjects less supportive of laws to help poor people.
What the hell is wrong with humanity?
Depressing? Maybe. But if you’re someone who tries to build support for social programs, there’s some important stuff here.
The paper is:
Sands, M. L. 2017. Exposure to inequality affects support for redistribution. Proceedings of the National Academy of Sciences of the USA. DOI: 10.1073/pnas.1615010113.
Big thanks to Evan Brock for his work on the Nails and String Puzzle Solution!
Man that guy can make graphics, eh?
Nice job, Evan. Thanks again.
If you ask a large group of people a question, to which only some of them know the right answer, how can you use their responses to find the truth? A new paper in Nature describes a method that the authors show works really well.
The paper is called:
Prelec, D., H. S. Seung, and J. McCoy. 2017. A solution to the single-question crowd wisdom problem. Nature. DOI: 10.1038/nature21054.
Puzzle 29 is called “Rolling a Six.”
Episode 28 is up. It’s about group decisions in schools of fish. There’s also a marvelous puzzle about Saskatchewan. And who doesn’t love a little Saskatchewan now and then?
Here’s the paper:
Couzin, I. D., J. Krause, N. R. Franks, and S. A. Levin. 2005. Effective leadership and decision-making in animal groups on the move. Nature. DOI: 10.1038/nature03236.
Episode 27 is up, and it’s a dandy. Cockroach groups are showing these smart behaviours. How can that be? We all know cockroaches are dumb, right? …or are they??? Decide for yourself.
The paper is:
Amé, J.-M., J. Halloy, C. Rivault, C. Detrain, and J. L. Deneubourg. 2006. Collegial decision making based on social amplification leads to optimal group formation. Proceedings of the National Academy of Sciences of the USA. DOI: 10.1073/pnas.0507877103.

Get your mind out of the gutter. This is about fluid dynamics! (Get your mind out of the gutter, again.)
