 Emanuel,

 Excellent post, I like the relevance of the concepts around misinformation.  These visualization concepts parallel familiar Information Operations and Information Warfare concepts.  I recall taking a machine learning course (over 15 years ago) by Professor Michalski at GMU's Machine Learning and Inference laboratory.  He mentioned that information could be evaluated over three axes: specificity, relevance, and accuracy/truthfulness.  I've used this rapid assessment tool for information in nearly every domain in my career since that course.  

  From what I have learned so far in this course, information assessment tools are equally useful in the visualization domain.  From a defensive stance, if we have 'gold copy' source data, we can evaluate the truthfulness of a visualization using the lie factor.  Evaluate specificity using assessment of scale, as you referenced Wainer's Rule #2.  Relevance is a bit harder, but likely the most important in online information sharing, since we see how seamlessly fake news can highjack major social issues for alternative intents.
