Of course I’m not 100% certain, but I think that years ago I made a mistake — one that has only really hit me with full force in the past couple weeks.
It’s actually a very simple matter: What I once considered to be a dichotomy is probably more of a trichotomy… and this three-state approach used in information retrieval logic is of immense importance (I may be overusing the three-state logic metaphor somewhat, but I am confident enough that it is valid to say “I don’t think so”).
This new and more nuanced approach helps to explain why the web is perhaps not as “scientific” as traditional professional, research and science publishing media are. In particular: the repercussions of the failure to distinguish all three aspects of the trichotomy may lead to grave errors that affect the measurement of data, and the assessment of reliability and validity of the shared data.
