Episode 31: Madagascar’s Most Mysterious Bat

Madagascar’s Eastern Sucker-footed Bat

This bat has adhesive organs on its wrists and ankles that it uses to hold on to the smooth surfaces of leaves. It can even hang upside down from a horizontal pane of glass! But that’s not what makes it Madagascar’s most mysterious microbat. Have a listen.

The paper is:

Episode 30: Does seeing the poor make people more generous?

Nope.

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.

Episode 29: How to Crowd-source Correct Answers

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.”
