The key argument is that cognitive tasks should be turned into design principles.

The central claim of the book is that effective analytic designs entail turning thinking principles into seeing principles.

Design cannot rescue failed content.

What about confusing clutter? Information overload? Doesn't data have to be "boiled down" and "simplified"? These common questions miss the point, for the quantity of detail is an issue completely separate from the difficulty of reading. Clutter and confusion are failures of design, not attributes of information.

Beautiful Evidence is about the theory and practice of analytical design.

My idea here is that, inasmuch as certain cognitive tasks and principles are tied to nature's laws, these tasks and principles are indifferent to language, culture, gender, or the particular mode of information that is provided.
