International Personality Item Pool is a public domain personality testing system. The Myers-Briggs Type Indicator test and other major personality testing systems are closed, proprietary systems – the scoring systems are opaque. They can’t be experimented with and modified or, most importantly, tested by those outside of the organizations who own them.
International Personality Item Pool is an open system for behavioral scientists, created by the Oregon Research Institute.
This IPIP Website is intended to provide rapid access to measures of individual differences, all in the public domain, to be developed conjointly among scientists worldwide. Later, the site may include raw data available for reanalysis; in addition, it should serve as a forum for the dissemination of psychometric ideas and research findings.

Is there a reason to call something open source instead of public domain? Or vice versa? Have those terms become interchangable?

1. Open “source” is technically a misnomer – only software or things with source code should be called “open source.” It’s become popular to call lots of other things open source, though.
2. Not everything that is open source is in the public domain. Usually it’s copyrighted but given a special license that allows people to modifify and redistribute the “source.”
3. The reason I think of this as “open source” is because it is released in the same spirit as open source software: to be examined and improved upon by the community, rather than simply sold to end users.
