I enjoyed listening to Bob Fischer the other day discussing animal welfare. I specifically liked his focus on how one should distribute a budget for charity between human welfare and animal welfare. Before he gets into the different philosophical or logical ways that people might approach the problem, he looks at a model for how we can assess animal suffering on the same scale as human suffering. He approaches this by assessing what he calls the relative Moral Weights of different species.

Thanks for reading Nick’s Substack! Subscribe for free to receive new posts and support my work.

In his research, as director of the The Society for the Study of Ethics and Animals, Fischer revisits experimental data and metastudies of different metrics both on what you might consider intuitive measurements (for example, should we consider how many neurons each animal has in its brain?) and harder evidence, (say, captive animals may exhibit distressed behaviours that we can measure without anthropomorphising their ‘emotions’) His results are well-argued and for the sake of this discussion I’m going to assume that they are justifiable and robust. He concludes that if we are comparing the suffering of a pig with that of a human, there might be a multiplier of something around say three. That means that the suffering of one distressed human might have the same moral weight as that of three pigs, but with a margin of uncertainty. An octopus might be a smaller differential (as we will understand if we have seen that Netflix documentary) and if we considered a shrimp we would see a bigger gap. 

Perhaps the most surprising conclusion from his research and the one he asked us to take away, was that if you are comparing human suffering and shrimp or insect suffering we should be considering factors of maybe tens or hundreds but not thousands or millions.  Interestingly with reference to that, when the discussion swung to saving people from malaria, it didn’t mention the plight of the mosquito at all.

The first thing we might wonder, is why this matters if we can never know what it feels like to be a shrimp. That’s why I think his metaphor of a charity budget was a good one. If we see that farmed shrimps suffer stress which causes physical damage or death, and let’s say I take a factor of 1/500 for the moral weight of a shrimp then yes, for every $500 I donate to human welfare why not donate one dollar to make shrimp farms more humane? Now put like that it even seems that perhaps 1/500 is being unfair to the shrimp. And of course we might look at how many humans my $500 helps and how much and how many shrimps my $1 affects and adjust my donations accordingly. Fischer also looks at how different people would assess these things and I won’t repeat that here, but he labels them as utility, risk aversion, futility, and ambiguity aversion, so we can note that there is a variety. It’s not an exact science.

It’s helpful to be able to use these logical analytical techniques to depersonalise these discussions. This helps us make good decisions about suffering, life and death which can easily become emotive and tribal, even political. So I would agree that this is a good starting point, and I am quite comfortable in using this kind of logic in choosing how to spend my money. 

But Fischer is also a professor of philosophy, so what about the famous ‘lever on a railway points’ dilemma? The runaway train is coming and I have to choose whether to push the lever on the junction one way to save the life of a human who is strapped to the rails of one siding, or to push it another way and save 500 shrimps, or three pigs, or an octopus. Which would I choose? Well, even on our worst day pretty well everyone would save the human. Wouldn’t we? Same maths same research, but for this thought experiment at least, an entirely different result.

So why is there such a discrepancy? I think it lies in the difference between consciousness and awareness, and that difference lies in what time means for different creatures.

Going back to my earlier essay on consciousness, I used consciousness and self-awareness fairly interchangeably. Perhaps I might better have suggested a spectrum going from intelligence through consciousness to awareness. Actually I think it’s more like three distinct steps rather than a continuum.

But firstly these words are woolly, so I have to define what I mean by them as I go. I was listening to a debate the other day between Steven Pinker and one Jagadish Vasudev (aka Sadhguru) about whether consciousness is a miracle. That interchange, I wouldn’t call it a discussion, didn’t resolve anything, because these two guys have absolutely different definitions of both the word ‘consciousness’ and the word ‘miracle.’ One was saying that if we remain deliberately unsophisticated, then we feel a sense of wonder when we observe nature, the other said that physical systems may still be logical even when they become so complex that they appear to transcend mechanism. Both of their points of view can live perfectly happily in the same universe, (Unlike for example a discussion on religion between Christopher Hitchens and Anne Widdecombe or one on truth between Donald Trump and any number of people who will never have the chance to debate it with him.) So when discussing stuff like this, it’s better if I define what I mean by these woolly words as I go along.  

Are all animals intelligent? Yes in my definition they are, and not just animals. The definition I am using here is different from what others may use, so I’m specifying it as the ability to take stimuli and then modify one’s own behaviour to optimise the result. All animals must be able to do that, because they have to carry out whatever actions they need to keep themselves alive. Some are hard-wired, some are explicit. I might say I am more intelligent than a bat even though the bat can catch a fly in mid air in the dark. Why is that? Well, it’s because I can consider abstract concepts of echolocation and triangulation and algebra and Newtonian physics. The bat could never grasp any of those concepts. So I am using some kind of active intelligence whereas the bat is just using muscle memory and intuition. Either way the calculation works, and actually much faster and more easily for the bat than for me.

None the less I’m ticking both our boxes for crossing the threshold of intelligence.  Japanese metro slime mould, any plant that turns to the sun, an abacus and my laptop all tick that box too, perhaps even a mousetrap, so it’s a pretty low threshold. It’s also easy to grade a scale up from the threshold and calibrate it experimentally.

I am tempted to feel that there are two kinds of intelligence here. One that we might call the hard-wired type of calculation, (and hard wired has an interesting etymology here because a computer does most smart stuff using the opposite of hard wiring) and the other being the explicit kind, where the knowledge is held outside of the organism and considered what we might call academically. But that distinction is actually what I am calling awareness and why I am making these distinctions at all, so bear with me.

Next up, consciousness. Perhaps generic consciousness or maybe the potential for cognition. Anyone who doesn’t think a dog or a horse or a cat has conscious has never looked one in the eye. But what does that mean? As a starting point, I’m calling consciousness the ability to differentiate self from environment and to reflect on that, even at a rudimentary level.

Perhaps the defining point then is humour? I googled – ‘do animals have a sense of humour?’ I got a couple of not very convincing results about rats laughing at hypersonic frequencies, abused bees becoming pessimistic, and gorillas finding double-meanings in sign language vocabulary. These animals are all showing something more than say our best AI models are doing at the moment. So I’ll give them a tick for cognition – meaning the ability to find meani…
