I love to debate. But there is a handful of people in the world I wouldn't want to mix it up with. Steven Pinker is one. He hardly stutters or stammers. His words come out like an essay already edited. And I dare say he's good on his feet. In this discussion of nature and nurture, he argues not only that evolutionary forces are at work in human beings, but that it is possible to test associated hypotheses.
Some may be surprised to learn that Pinker is classical liberal in orientation. Many classical liberals rely on a tabula rasa or "blank slate" concept of the person. Under such a conception culture and experience 'write themselves' upon the person, who is -- for the most part -- malleable. But this is wrong. And if we think of culture and evolution working in tandem, we'll get a lot further -- not only in our thinking, but in our communication strategies.
For example, as we've discussed before, people have evolved political predilections. To deny these predilections is to suggest we can simply erase the slate and start over with better ideas. But this is a terrible approach to social change. Instead, we have to practice more audience segmentation, then start by appealing to what may be the predilections of that audince. Then we can leverage said predilections to make the classical liberal case. That's our best hope. Otherwise, we're awkwardly presenting what - to us - seem like rational arguments, but to others is hopelessly misguided from the start.
Ironically, Pinker may not have convinced the others in that clip of his evolutionary approach. Maybe he didn't practice what he preaches in terms of evolutionary theory as it intersects with a communications strategy. Hard to say from this clip. In any case, he's a blisteringly logical debater. And in his books he has the uncanny ability to employ metaphor and emotion in service of his arguments. That's where the the most effective communication happens. That's where Greeks had it right.
