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.”

Episode 27: Cockroaches Divide Without Counting

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:

The puzzle this week is called “Nails and String.”
