User could follow someone else's made trail, such as reading this wiki, instead of researching everything themselves. Uncommon problems, and the exploration inherent in science, require custom data sources that have not been documented here. Greed motivates many companies to make fake and useless devices and interventions. Many of the issues described on this page, data access<ref>https://quantifiedself.com/about/access/</ref>, data quality (devices often cover up bad signal with guesswork), and price are all constraints which make finding a good enough device harder.

Uncommon problems, and the exploration inherent in science, require custom data sources that have not been documented here. Learning enough about health and statistics takes time too.

 

Greed motivates many companies to make fake and useless devices and interventions. Many of the issues described on this page, data quality (devices often cover up bad signal with guesswork), data oversimplification, data access<ref>https://quantifiedself.com/about/access/</ref>, and price are all constraints which make finding a good enough device harder. [[Commercial, Medical Device, or Open Source|Medical and Open Source]] devices have their own issues. Afterwards the explorer will have to aggregate data ([[Open Humans]]), parse new [[Data format structure variables|data format]] and clean the data.
