In addition to having data on their own, both psychology and neuroscience are influential in how we process and interpret data. Humans will often read data in a specific way that often opens up room for misinformation. These disciplines can help us understand how we read data and develop sufficient data literacy skills to combat manipulated understandings of data. For more on this, check out this article on how these two disciplines can better help us navigate understanding data.
Psychology data is often interlinked with a variety of other disciplines. For example, psychology data often overlaps with data in the social sciences and health sciences. Depending on the project, it may be worth checking out data resources from other disciplines, but here are some general psychology databases as a starting point:
