Bringing big science to psychology

Chawla describes a new initiative dubbed the "Psychological Science Accelerator" (PSA) that:
...has so far forged alliances with more than 170 laboratories on six continents in a bid to enhance the ability of researchers to collect data at multiple sites on a massive enable researchers to expand their reach and collect “large-scale confirmatory data” at many sites.
A selection committee has evaluated eight proposals and selected one based on experiments already replicated in the US and the UK.
It aims to discover whether the research findings of Alexander Todorov, a psychologist at Princeton University, can be replicated on a global scale. Todorov has reported that people rank human faces on two components: valence and dominance. Valence is a measure of trustworthiness, whereas dominance is a measure of physical strength...More than 50 of PSA’s collaborating labs have already committed to collect data as part of the study.
PSA isn’t the only effort aiming to change how researchers conduct psychological studies, which have received extensive criticism for a lack of reproducibility. Others include the Many Labs Replication Project and the Pipeline Project. Earlier this year, Chartier also launched StudySwap, an online platform designed to help researchers find collaborators for replication studies and exchange resources.
