Future of CoDa

Vision for the future of CoDa

 

Entry of newly published studies

We aim to keep CoDa up-to-date with the published literature. We have two strategies to achieve this goal. First, our team can train PhD students to annotate studies. This is a valuable learning exercise for students and their work directly benefits the field. Contact the CoDa team if you would like to collaborate. Second, we will offer a tool for authors who publish studies on cooperation to annotate their own study. Authors can provide a machine-readable translation of their published PDF paper and dataset that can be directly added to CoDa.

Entry of file drawer studies

Researchers are less likely to publish null findings. We plan to implement a method for researchers to annotate and report their own null results with the field, especially in a time and cost efficient way. Researchers can complete a brief form about their study methods and results, and this information will be reviewed by an editorial board and subsequently added to CoDa. Researchers can cite these machine-readable reports and authors can be recognized for their contribution.

Include other paradigms and languages

We intend to expand the databank to include studies using different paradigms to study cooperation (e.g., the trust game, dictator game, ultimatum bargaining game, stag hunt and other coordination games). Our goal is to also annotate papers that have been published in additional languages, besides English, Japanese and Chinese.

Quality control

During the development of CoDa, we did our best to reduce human error in our annotation of the literature. Indeed, we found substantial inter-rater agreement on most variables. Visit our Codebook to check the agreement scores. That said, CoDa does contain errors and we can crowd source identifying and correcting these errors. Please notify us when you spot an error in the annotation of a study.

Collaborate

We are open to collaborations to maintain and further develop CoDa. Contact the CoDa team if you have an interest in collaborating on some aspect of CoDa.
