The Role of Empathy in Science

Jane Goodall's career was not just a watershed in ethology and primate psychology, but in the way science is done.

I vividly remember reading Jane Goodall's descriptions of the chimpanzees in her Gombe project. Here we had been looking for intelligent alien life with SETI, and wondering about life on Mars. But she revealed that intelligent, curious personalities exist right here, on Earth, in the African forest. Alien, but not so alien. Indeed, they loved their families, suffered heartbreaking losses, and fought vicious battles. They had cultures, and tools, deviousness and generosity. 

What was striking was not just the implications of all this for us as humans and as conservationists, but also what it overturned about scientific attitudes. Science had traditionally had a buttoned-up attitude- "hard science", as it were. This reached a crescendo with behaviorism, where nothing was imputed to the psychology of others, whether animals or children, other than machine-like input/output reflexes. Machines were the reigning model, as though we had learned nothing since Descartes. 

Ask a simple question, get a simple answer.

This was appalling enough on its own terms, but it really impoverished scientific progress as well. Goodall helped break open this box by showing in a particularly dramatic way the payoff possible from having deep empathy with one's scientific object. Scientists have always engaged with their questions out of interest and imagination. It is a process of feeling one's way through essentially a fantasy world, until one proves that the rules you have divined actually are provable via some concrete demonstration- doing an experiment, or observing the evidence of tool use by chimpanzees. It is intrinsically an empathetic process, even if the object of that empathy is a geological formation, or a sub-atomic particle. 

But discipline is needed too. Mathematics reigns supreme in physics, because, luckily, physics follows extremely regular rules. That is what is so irritating and uncomfortable about quantum mechanics. That is a field where empathy sort of fails- notoriously, no one really "understands" quantum mechanics, even though the math certainly works out. But in most fields, it is understanding we are after, led by empathy and followed by systematization of the rules at work, if any. This use of empathy has methodological implications. We become attached to the objects of our work, and to our ideas about them. So discipline involves doing things like double-blind trials to insulate a truth-finding process from bias. And transparency with open publication followed by open critique.

In the 20th century, science was being overwhelmed by the discipline and the adulation of physics, and losing the spark of inspiration. Jane Goodall helped to right that ship, reminding us that scientific methods and attitudes need to match the objects we are working with. Sure, math might be the right approach to electrons. But our fellow animals are an entirely different kettle of fish. For example, all animals follow their desires. The complexities of mating among animals means that they are all driven just as we are- by emotions, by desire, by pain, by love. The complexity may differ, but the intensity of these emotions can not possibly be anything but universal.

Renewable Power in Africa

Prospects for growth in electricity access and in clean energy.

Africa is an enormous continent, notoriously larger than China, the US, and Europe combined. Its population is also large- as large as that of India, at about 1.4 billion people. This population is growing rapidly, while its social and economic systems are developing more slowly. But as we know, the main ingredient of an advanced economy is power, which as traditionally been drawn from fossil fuels. Advanced economies are in the painful and reluctant process of transitioning away from fossil fuels. We can do a lot to help Africa to leapfrog this history by front-loading renewable energy.

There was a recent paper about the hydropower prospects in Africa. It notes that there are many projects on the drawing board, with many undammed rivers on the continent. But as we have learned in the US, the implications of river damming are quite destructive and wide-spread. For example fish ladders simply do not work- not at the scale needed to keep fish populations (and fisheries) healthy. Then there are problems of siltation, water temperature, erratic flows, and population displacement. There is a movement in the US to remove dams wherever possible, to free ecosystems back to a functional state. 

"More than 300 hydropower plants, corresponding to an additional 100-GW power capacity, are under consideration across the continent."

The article made the basic point that, given the state of other renewable power sources, and the prospect of lower water levels and droughts due to climate change, that roughly half of the planned hydropower projects they know of are economically inviable, even putting aside environmental considerations. 

This leads to the question of what to do instead? Maybe the answer is microgrids. In the developed world, it is increasingly common for people to take control of their own electricity production through the use of solar power. But at a single house level, power inputs and consumption are both erratic and require a lot of storage capacity to furnish a reliable system. The typical system is highly reliant on the larger grid to manage this intermittency. Microgrids occupy a middle range between grid-scale power, which is subject to problems of centralized political and social development, and the individual house, where the expense of managing fully independent electrical supply is highest.

These maps note that there are many underserved areas in Africa- some concentrated urban areas, and a great spread of rural areas. Electrification is well-advanced in South Africa and the heart of West Africa. But there are many rural areas that would be better served by microgrids of various scales. Microgrids can be altered over time and integrated into larger systems. Their production and storage capacities are both beneficial for larger grid stability and scalability. Africa is, naturally, positioned ideally for solar power, and the Sahara is a natural location for massive power installations, to serve both Europe, the Middle East, and Africa.

One of the main characteristics of renewable power is that it has high up-front costs. The fuel is free, and clean. But the mechanisms to capture and store it are expensive. Thus if we want to encourage a more rapid transition to sustainable power systems in Africa, we would help pay for the up front costs, sharing capital investment in the interests of everyone, both here and there. Africa is currently a big exporter of oil and gas. As other regions transition away from those fuels, it is imperative that this production not be redirected and propped up by further Western investment, but rather replaced with better energy sources.
