In 1981 Robert Axelrod famously hypothesized that international cooperation might evolve through direct reciprocity. In our new article in Science Advances, we present new evidence for that hypothesis. Using a new method and dataset, we're able to detect direct reciprocity in a relatively large number of country pairs. Reciprocating country pairs exhibited higher levels of stable cooperation, and were more likely to punish (yet quickly forgive) instances of non-cooperation, in an effort to maintain cooperation. By contrast, countries without reciprocal strategies were more likely to exploit each other's cooperation and abandon mutual agreements. The results indicate that policymakers of powerful countries—who may be tempted to take sweeping, non-cooperative action in areas like trade or environment—should consider the long-term negative effect of non-reciprocal tactics.
There are over one million registered charities in the United States alone, and many more worldwide. How do you choose among them? MyGoodness is a simple game that helps you understand how you give. You make 10 giving decisions. Each decision is between two choices, and you tell us which you prefer. At the end of the game, we give you a summary of your ‘goodness’ and how it compares to others. You can share that feedback with whomever you would like.
This Halloween, we present Shelley: the world's first collaborative AI Horror Writer! Shelley is a deep-learning powered AI who was raised reading eerie stories collected from r/nosleep. Now as an adult, and not unlike Mary Shelley - her Victorian idol - she takes a bit of inspiration in the form of a random seed, or a short snippet of text, and starts creating stories emanating from her creepy creative mind. But what Shelley truly enjoys is to work collaboratively with humans, learning from their nightmarish ideas, creating the best scary tales ever. If you want to work with her, just respond to the stories she would start every hour on her Twitter account, and she will write with you the first AI-Human horror anthology ever put together!
