I do believe that there are some universal cognitive tasks that are deep and profound - indeed, so deep and profound that it is worthwhile to understand them in order to design our displays in accord with those tasks.

The speculative part of my work is that these particular cognitive tasks - ways of thinking analytically - are tied to nature's laws.

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.

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

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

Design cannot rescue failed content.
