Description

This dataset contains the data and replication code for the paper "Homo cooperans: Understanding the nature of human cooperation", published in Science. Summary: Using globally representative data from an incentivized two-player cooperation experiment conducted in 125 countries (N = 101,123), we assess the extent of human cooperation and study its individual determinants. Across the globe, about two-thirds of people choose to cooperate. The decision to cooperate is significantly shaped by cooperation beliefs, injunctive norms, and preferences. Effect sizes of these determinants vary across countries, a variation that is systematically associated with historical and cultural markers. Globally, people underestimate others’ willingness to cooperate — humans are more cooperative than they believe. A simple information treatment reduces misperceptions and causally increases cooperation.

Expected crawler behaviour

Use a stable, truthful User-Agent with product/version and a working contact URL. Across all IP addresses and HTTP connections used by one crawler identity, allow no more than 5 requests in flight and wait at least 20 seconds between request starts. Crawl URLs listed in the catalog sitemap, including file pages and download URLs when they are published, use conditional requests, honor Retry-After, and apply exponential backoff after errors.

The welcome page may link to the interactive repository for human navigation. Automated clients must not treat that human link as a catalog crawl target.

Read the live machine-readable crawler policy before and during a crawl. Stop crawling when it reports CPU or memory utilization at or above 80% and 80% respectively.
