Confusion and clutter are failures of design, not attributes of information. And so the point is to find design strategies that reveal detail and complexity - rather than to fault the data for an excess of complication. Or, worse, to fault viewers for a lack of understanding.

Good design is a lot like clear thinking made visual.

That is to say, nature's laws are causal; they reveal themselves by comparison and difference, and they operate at every multivariate space, time point.

It is not how much empty space there is, but rather how it is used. It is not how much information there is, but rather how effectively it is arranged.

A curious consequence is that I have become a minor celebrity.

There is no such thing as information overload, just bad design. If something is cluttered and/or confusing, fix your design.

I think it is important for software to avoiding imposing a cognitive style on workers and their work.
