About Us

It started with a challenge: how do psychology students collect more data for their research? We built the site originally as a side project but now our open source data has proved useful for researchers around the world.

The Personality Data Project

How started and why is the online evolution of The Personality Data Project. A team of graduate psychology students started the open source project in 2018 as an after-labs side-project. Whilst writing their research, they found it difficult to get accurate data on personality traits, and in particular they found it difficult to get enough research participants to take their questionnaire trials (we always need more data!). When they spoke to other students they found this was a common problem, so the the students built a platform where personality data could be collected, analyzed, and published. Since the project was setup in 2018, the network of contributors has grown and the importance of the website has become apparent; the best way to gather large volumes of self-report data on personality is to host the questionnaires on a website with high-traffic; was born.

The project's aim is simple: help psychology reserachers further what we know about personality.

Now university students, lecturers, and researchers from around the world all contribute to ensure is up-to-date and accurate. Psychology students from hundreds of different universities have now used the website to host their personality questionnaires and where the results are relevant, publish the findings online in a clear format.
