Naughty and Nice

A small Christmas blog on the ethics of being overheard . . . he’s making a list, he’s checking it twice . . .

Amazon have put all five seasons of Person of Interest on Prime. Person of Interest is an amazing exploration of what it might cost humanity to create artificial intelligence, and its beautifully prescient given Amazon’s recent Alexa data breach where a user was able to access another user’s recordings.

In my book (which if you’re looking for a last minute Christmas gift, do check it out) I talk about how we might end up studying personality through artificial intelligence, and the ethics of how we might consider this data use.

I’m delighted with my Christmas present of Person of Interest. I cry the whole way through this show. It is amazing. But I also have an Alexa sitting in my house, and a Google phone. Occasionally my phone flashes its screen, saying “I didn’t recognise your voice”, much like Athena’s ears prick when she’s snoozing and hears me get to my feet. Do I need to listen for you right now?

On the other hand, in 2018 I’ve also had to balance the issue of not having ethics committee permission to share sensitive data and the challenges that has caused for making my research open and reproducible. I am proud particularly of this repository which will be elaborated on in a publication next year – how we can be reproducible when we’re dealing with data that should be confidential. But yes, privacy is a challenge.

And it’s a very strange conversation to have in December. He sees you when you’re sleeping, he knows when you’re awake . . .

Recently, I was asked how old I was when I understood about Santa. It actually ties in to my first experience with religion. I was raised without any religion whatsoever, and when I got to school I was introduced to this whole new concept. That my own mind and actions were not my own private space, that someone or something might be watching. I made a deal with this ‘God’ (who I pictured as Danny Devito in a toga, I do not know why). If I was very good, he would reward me with a hotdog on Friday at lunch time. As one of the Mac kids, I was always at the middle of the lunch queue and the hot dogs were always gone. So I was very, very good for a whole week. I did the praying. I was kind. And on Friday  . . . there was no hot dog.

The only other experience I had with religion was one of my grandfathers who had cryptically said “Any God who doesn’t want me isn’t a God I want to believe in”, and at the age of 5 I sanguinely accepted this logic, and decided the lack of hot dog meant God had no interest in my soul. That Christmas I tried this logic again, and created my perfect toy (a My Little Pony toy of my favourite character – except there would be movable bits). Santa did not come through.

We teach morality to children with the idea of oversight. Perhaps not entirely, but ‘being watched’ is a large component of how we learn our own moral frameworks. The Good Place has made an excellent TV show exploring the concept of being constantly observed (and measured). It’s probably not a coincidence that we’re interested in these stories right now. But it’s also not a coincidence that I got thinking about this after realising I knew more than I wanted to about my new neighbours.

Ultimately I think data collection and analysis is an organic process, and it’s very hard to draw a line over ‘good data collection and analysis’ and ‘bad data collection and analysis’. Amazon absolutely should not be sending clips of audio to a random stranger. But should I hear random snippets from my neighbours’ lives? How often should we accept being ‘overheard’ as a price of being digital neighbours?

I don’t have an answer for this – or even a reason to blog about it on Christmas eve. I just think it’s a very interesting question.

Ritual Slaughter and Animal Welfare

Quite a few people thought I should talk about the Independent’s story: Denmark banning kosher and halal meat. 

One of the people who thought I should talk about it was my cousin who’s currently doing a PhD in philosophy. Understanding somebody else’s PhD topic is always tricky, but to my knowledge, she’s investigating the rights of minority groups, e.g. religions, in liberal societies. There’s a fundamental conflict in a society which likes to believe everyone has the right to practice their beliefs when those beliefs might compromise the rights of others in the society. Whose rights should be most protected?

Now I am neither Muslim nor Jewish, I’m a staunch atheist. I’ll talk about this as objectively I can, and it’s not my intent to insult anyone.

Firstly – Halal meat is meat killed in accordance with Islamic laws. The animal is slaughtered in the Dhabīḥah  method which involved the animal’s carotid artery being slit and the aim of this is to kill the animal as quickly as possible to reduce suffering. It’s important to note this – for years halal was considered good welfare. The law is there to promote good welfare as traditionally, Allah wants us to look after the animals.

Jewish dietary law is called kashrut, and foods which obey these laws are kosher. Only clean animals may be eaten and clean animals are cloven hoofed cud-chewers (ruminants), but not animals which digest in the hind gut or do not have a cloven hoof. There’s a list of flying animals that it is not okay to eat, such as birds of prey, bats, fish-eating birds, and you can only eat sea-dwelling animals that have both fins and scales. Incidentally, and in the light of my last post, I do have a Jewish friend who likes to point out that giraffes are kosher. Poor Marius never stood a chance in Denmark. The ritual slaughter of kosher animals is similar to halal, a precise cut to the throat severing the carotid, jugulars, vagus nerves, trachea and oesophagus. The shochet, the man who kills the animals, traditionally should be a good Jewish man with great respect for the religion, and therefore a respect for the suffering of the animals.

Both of these methods promote good care of the animals, respect for the animal being slaughtered, and – and I think this is really important – traceability of meat. They both tick a lot of my boxes. They protect human interest by showing due care and attention to the food chain and food hygiene, and they protect the animal’s interest by showing them respect and killing them in what is perceived to be the best way of avoiding suffering.

So why do Denmark have concerns over halal and kosher meat?

I expect it’s to do with the lack of stunning. Gregory et al (2009) compared three forms of killing beef cattle by investigating the blood found in the trachea. They compared shechita (no bolt stunning beforehand), halal (no bolt stunning beforehand) and bolt stunning plus ‘sticking’ (the method of slaughter is mechanically the same but because it is stunned beforehand and there’s no prayer it the religious terms are not accurate). Now note first off that this study does have a flaw in that it’s not the same person killing all these animals, because then it would not be true shechita/halal, so some of the variation here cannot be attributed to the method but the slaughterer. All three methods found animals which had blood in the trachea (the shechita slaughtered animals had the least amount of blood in the trachea with only 19% of animals showing blood there, with the 21% of the stuck animals showing blood and 58% of the halal animals). The blood reached down as far as the upper bronchi (indicating quite a lot of aspiration of the blood, e.g. the animal was sucking down a breath of blood) in 36% of the shechita animals, 69% of the halal and 31% of the stuck animals. There was a bright bloody foam in the in the trachea of some of the animals (indicating air being forced through the blood) in 10% of the shechita, 19% of the halal and 0% of the stunned animals. The authors concluded that the animals killed without stunning could suffer a welfare challenge from the inhalation of blood before they lose consciousness.

In 2010, Gregory et al looked at how quickly halal slaughtered cattle collapsed after the cut was made. 14% of the animals studied stood again after collapsing. This demonstrates that consciousness is not lost, and so the method, wonderful though its intent may be, does not work as it should.

Another interesting religious dietary law is that Sikhs cannot eat either halal or kosher meat. Sikhs believe that ritual slaughter which involves prayer and a protracted death is an unnecessary level of ritualism and isn’t appropriate. Instead they slaughter their meat animals using the jhatka method which should completely sever the head from the body of the animal in one blow, minimising suffering. (Incidentally, I haven’t been able to find out if Denmark still allows jhakta meat, please let me know if you have info on this).

The EU has a directive on animal slaughter which requires stunning unless the member state wants to exempt a religious group from the directives rules. Denmark has decided no longer to allow this exemption for religious groups. Some papers have looked at what it would take to have Islam accept stunning as part of halal slaughter (Nakyinsige et al, 2013, spoilers – there are ways to have halal meat with stunning)

But! I just want to point out one last thing. When we’re assessing welfare in slaughterhouses, we use ‘success of stunning’ as a welfare measure (Grandin, 2001, Grandin, 2010). Stunning is not the end to all slaughter related welfare problems. Who has the right to tell religious groups what they can and cannot do? Well I have a personal opinion about that, but I think that science’s role in this debate is to investigate welfare indicators, to find reliable and safe methods of slaughter, and not to forget that many of these dietary rules come from a desire to protect welfare. And it is my job as a member of my society to say I’m worried about animal welfare at slaughter.

One last thing. While I’m concerned about halal, kosher and even jhakta meat, I have eaten the first two and would eat the third. I’m considering making a goat curry and the local butcher who does goat is a halal butcher. But I rarely ever buy Danish bacon. In part because I want to support the British pork industry, but in part because I have welfare concerns about the farming of Danish bacon. Rightly or wrongly, I have more concern over the policy differences between my country and Denmark, than I do over ritually slaughtered meat. I wonder how right I am about that.

Edited to Add – An acquaintance of mine with more experience on the slaughter side of animal welfare had a few good points to make about this article, which I will share here.

  • There’s a difference between small ruminants and large ruminants in using cut-throat slaughter. Smaller animals tend to lose consciousness within 8 seconds and so the worries about consciousness and suffering that Gregory et al raise are less of a concern for my goat curry (I am making that goat curry soon – I can taste it already . . .)
  • And two – the animal’s life before slaughter is such an important component of animal welfare that my last point may be misleading for the layperson. We need lots of research on slaughter, all forms of it, but how we care for food-production animals in their lives is one of the biggest welfare challenges facing our society.
