In 1,930 individuals aged 25 to 85 years from the SOEP-G[ene] cohort, the magnitude ...

Eighty-five independent teams attempted numerical replication of results from an original study of policy preferences and immigration. Reproduction teams were randomly grouped into a ‘transparent group’ receiving original study and code or ‘opaque group’ receiving only a method ...
