(Note: I work at System)

First, thanks! If you'd like to reach out and learn more or talk about your learnings from building something like this we'd be very interested (we have a Slack community and a direct contact form on the site).

As for your questions - we have tools for assessing the reproducibility (in the statistical sense) of models and relationships added to System, as well as tools for users (and built in to the platform itself) to assess the relative statistical strength between any two relationships that you find on the site.

And, yes, we're early on in the process of writing (peer-reviewed) evidence on various topics, and as you note, the value of seeing these systems will grow with how detailed the topics are covered and the overall number of the world's topics shown to be related. I hope you'll stay engaged to see!
