That's it

I'm back in Red Rock for the summer. Cell phone and internet access is not available here so Journal updates will be sporadic at best. In fact if this summer's posts follow last years pattern, I won't be posting again until I head back out on the road in the fall. We'll see...

Genetic Determinism and Human Nature

The "implication" that seems to worry people the most is so-called genetic determinism - the notion that if human nature was shaped by evolution, then it's fixed and we're simply stuck with it; there's nothing we can do about it. We can never change the world to be the way we want; we can never institute fairer societies - policy-making and politics are pointless.

Now, that's a complete misunderstanding. It doesn't distinguish between human nature - our evolved psychology - and the behavior that results from it. Certainly, human nature is fixed. It's universal and unchanging, common to every baby that's born, down through the history of our species.But human behavior, which is generated by that nature, is endlessly variable and diverse. After all, fixed rules can give rise to an inexhaustible range of outcomes. Natural selection equipped us with the fixed rules - the rules that constitute our human nature. And it designed those rules to generate behavior that's sensitive to the environment. So the answer to genetic determinism is simple. If you want to change behavior, just change the environment.
