BOOK REVIEW : A Hunter-Gatherer's Guide to the 21st Century : Evolution and the Challenges of Modern Life by Heather Heying and Bret Weinstein


 
The challenges which face us as a species are legion. What should we do?

First we have to know who we are and where we are. We need to understand our programming and the ways in which it interfaces with the world around us, both its natural elements and those we have constructed.

The central challenge is one of hyper-novelty. Our instincts change extremely slowly and so are still adjusted to the way we were living many thousands of years ago. Culture changes more quickly, but still requires much time to test its innovations. A technological advance can spread throughout the world almost instantaneously, but a culture of social habits which allow it to be used for our net benefit rather than net deficit might take decades. Social media gives a case in point. It has brung us great benefits, but we are struggling to know how to manage downsides such as addiction and toxic forms of social interaction.

Heather Heying and Bret Weinstein set out in this book to provide us with tools which we can use to orientate ourselves and begin to improvise strategies for a liveable future.

I sometimes become annoyed with people who interpret human psychology with an evolutionary lens. Clearly our psychology exists within the process of evolution, but it sometimes seems as if people will use evolution as an excuse to reduce everything to the question of what does or does not lead to the prospering of the genes. So we are told that people wear ostentatious clothes for the same reason that some species of bird have bright feathers, i.e. it helps to attract a mate. That is all very well as far as it goes, but it doesn’t acknowledge that a post-menopausal woman may wear fancy clothes because it feeds her ego to get attention. The authors talk about rape as a product of evolution - a reprehensible form of reproductive strategy. This makes sense, but the rape of non-impregnable individuals is very common. Men rape other men and they rape prepubescent children. Rape can be an expression of a distortion of the ego which does not confer any benefit on the individual's genes.

So it seems to me that, just as culture is nested within and interacts with the system which is the genetic evolution of the species, so the psychology of the individual is nested within genetic evolution and culture, and it would be foolish, in trying to understand it, to reduce it to a role of servant to that larger system. Very often we are not even servants, but rather saboteurs, to ourselves.

This is just to give some idea of my own biases. I was not disappointed in the way this book approached the topic of evolutionary psychology. It emphasises the importance of viewing cultural evolution as being in service of genetic evolution. Just as mutations in genes lead to variations which either persist or don’t depending on fitness for life in the environment, culture is a series of experiments (conscious in this case) which lead to changes in society which either prove adaptive or not.

If an aspect of culture is costly in effort or resources and persists for a long time, then we can assume that it is adaptive in some way. The authors call this “The Omega Principle”. This doesn’t mean that the content of this cultural form is necessary true. It may be a myth which encourages socially beneficial behaviour. If a tribe believe that anyone who steals will go to Hell, it will probably lead to them being more cohesive and prosperous even if it isn’t true.

One of the key influences on this book is G. K. Chesterton. You may get a little sick of just how many times the author’s refer to “Chesterton’s fence,” but it is understandable given what a useful analogy it is. Chesterton pointed out that, if you are walking across a field and you see a fence and you don’t know what the fence is for, it is a really good idea to find out before you tear it down. This is Conservatism 101. Tradition is the wisdom we have inherited. Be careful that any change is going to be in your own best interest.

There is an interesting balance between this caution and the authors’ acknowledgement that, at this crisis point of hyper-novelty, we need to prioritise consciousness over culture. Culture is the repository of old solutions and consciousness is what we use to find a new path. I suppose the idea is that we need to learn the lessons from culture in the process of finding a new way.

There is plenty of practical advice in the book, grouped in bullet points at the end of each chapter. A lot of it centres around limiting hyper-novelty - processed foods, pharmaceuticals, unnatural light, etc. There is much parenting advice. And a lot about getting out into nature and being more sociable in person. Their argument against watching pornography seems like very sound advice for others, though I won’t be following it myself. I’ll also give spending time in potentially dangerous wild environments a miss for the time being.

One part of the book I found very interesting was their comment on the growth in diagnoses of autism and the way they link it to young children being “babysat” by screens. This fits well with what I have read from some other writers and it makes complete sense. I’m curious how it will be received though. In the past, explanations posited for psychological disorders which centred around the behaviour of parents have been very strongly resisted.

It’s a book which is very easy to read and full of fascinating information. I never knew that we humans can be usefully thought of as a kind of fish.

The final chapter deals with the question of where do we go from here - how do we secure ourselves a future. The key insight is that we need to find a psychologically satisfying alternative to material growth. We need to be exploring and utilising a new frontier - “The Fourth Frontier” - because it won’t satisfy us to stagnate without adventure. It has to be something other than maximising our exploitation of the Earth’s resources in the service of an increasing population and its indulgence. It’s a fuzzy picture, but I suppose it has to be. It can’t be someone’s planned utopia. It has to be something emergent from the interactions of us all. Thus it can’t be knowable in advance.

I also highly recommend the authors' Dark Horse podcast.
