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.
I hope that I am generous and tolerant, but certainly on the intellectual side I think that there are discoverable truths, and some things that are closer approximations to the truth than others.
I was writing a chapter of Beautiful Evidence on the subject of the sculptural pedestal, which led to my thinking about what's up on the pedestal - the great leader.
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.
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.
