She was one in a million, so there’s five more just in New South Wales.

She was one in a million, so there’s five more just in New South Wales.

We’re not good at large numbers. Our brains are adapted to living in groups of perhaps 150 individuals. City living is a very recent innovation, and our psychological mechanisms struggle to cope with it. One way in which we may go astray is through the misapplication of heuristics that worked well for our ancestors, but which misfire in very large groups. Suppose you learn that there is a person in your group prone to violence without provocation. If you live in a group of 150 individuals, you need to be on high alert: your paths will cross. But if you live in a city of 5 million people, you really shouldn’t worry (unless you have some reason to think the violent individual lives in your street). In fact, on learning that there is such an individual you will probably feel more anxiety than you should – not as much as you would if you knew your paths would cross, but more than you rationally ought to.Read More »She was one in a million, so there’s five more just in New South Wales.

Free the trolls

You do not have a right not to be offended,  insulted or verbally abused. You do not have that right because it might be right to offend, insult or verbally abuse you. You might believe stupid things, or even sensible things, and take offence at any and all critiques, rebuttals and refutations. You might be a pompous prig, a sanctimonious sop, an officious orifice. Even if you are not these things, there would be very little wrong in telling you you are. After all, you are not a six-year old child: you’re an adult. You can take it.

What of someone expressing their detestation of you, their hatred of you, wishing you ill, wishing you dead?

Blessed are the wastrels, for their surplus could save the Earth

Reposted from an article in “the Conversation”. 

In a world where too many go to bed hungry, it comes as a shock to realise that more than half the world’s food production is left to rot, lost in transit, thrown out, or otherwise wasted. This loss is a humanitarian disaster. It’s a moral tragedy. It’s a blight on the conscience of the world.

It might ultimately be the salvation of the human species.

To understand why, consider that we live in a system that rewards efficiency. Just-in-time production, reduced inventories, providing the required service at just the right time with minimised wasted effort: those are the routes to profit (and hence survival) for today’s corporations. This type of lean manufacturing aims to squeeze costs as much as possible, pruning anything extraneous from the process. That’s the ideal, anyway; and many companies are furiously chasing after this ideal.Read More »Blessed are the wastrels, for their surplus could save the Earth

Epidemics or Extremists?

Following six months in the UK with no access to a television, I’ve had the opportunity to rediscover the delights of prime-time news media exposure since returning to Australia.

If I had to point to the (world) issue that is foremost in the media’s minds at the moment, I would probably gesture wildly at the current concerns over the conflict with ISIS (or ISIL) in the Middle East. Indeed, it seems so important to the public that it is one of the few causes that currently has complete bipartisan political support; and to such an extent that the current Treasurer has been (subtly) reprimanded by Prime Minister Tony Abbot for daring to question the Opposition’s commitment.Read More »Epidemics or Extremists?

The Isis Propaganda War and its Moral Consequences

Islamic State (Isis) is using a variety of social media tools to spread their jihadist message across the globe. While some are rather odd, such as the internet meme of #catsofjihad, which combines cats with weapons, others are highly sophisticated, as Steve Ross details in his comprehensive article on the media tools Isis is using. Isis is distributing documentary-style videos in several languages which come with their own Hollywood-like trailers, propaganda tweets that detail the supposedly good Isis is doing, and footage of gruesome combat actions which at times is intertwined with video game footage. But nothing attracted more media attention than the videos of hostage killings such as the latest of the beheading of Alan Henning. While all the other parts of the Isis propaganda make sense to me, I had a hard time understanding why publish such horrific videos: How could such appalling videos help recruitment?

To veil or not to veil?

As recent media coverage has documented, Muslim veils are a hot button issue at present.

Research suggests that “a major determinant of who is most vulnerable to anti-Islamic abuse may be the degree to which the individual is visibly identified as Muslim” (King & Ahmad, 2010, p. 886). For Muslim women, one such identifier is a veil. A veil can refer specifically to the hijab or head- scarf, covering just the head but leaving the face exposed, or the full-face veil, which covers the head and face. Hate crime and prejudice directed against Muslims seems to be strongly linked to such visible markers of “difference” (Dreher, 2006), and political discourse has used veils to represent “the problem of Islam” (Watson, 1994)

In recent work published in the Journal of Applied Social Psychology, I explored the way that such prejudice against Muslim women wearing veils may differ as a function of which particular veil is being worn. You can read the paper here for free (it’s open access), and so I won’t go into too much detail about how study and the psychological literature on prejudice and first impressions.Read More »To veil or not to veil?

Dehumanization and terrorism

Most people would agree that terrorism is no good. The word itself is rich with moralized connotations. It is true that some have argued that terrorism might sometimes be justified, but in popular discourse, terrorism is typically deemed obviously horrible.

What are the consequences of branding some action an act of terrorism, or of branding some group a terrorist group? Note, in connection with this question, the ratcheting up of rhetoric surrounding ‘cyberterrorism,’ with many government officials now listing it as a major ongoing threat (e.g., here and here).Read More »Dehumanization and terrorism

Supermarkets, Spending, and Influences on Choice

Something of a twitter storm erupted last week over a poster placed in a supermarket window. The poster, placed in a branch of Sainsbury’s, issued a “50p Challenge”, urging employees to encourage every customer to “spend an additional 50p during each shopping trip between now and the year’s-end”. After a passer-by named Chris Dodd took a photo of the poster and posted it on twitter, a Sainsbury’s representative confirmed that the poster was intended only for employees and that it was not intended for public display.

How Much Freedom Should We Give Up To Avoid the Spread of Infectious Diseases?

The first patient to be diagnosed with Ebola outside of West Africa has been reported. He is now in the US, receiving treatment. He arrived from Liberia via Brussels before reporting symptoms, which were initially mis-diagnosed and treated with antibiotics.

If I were in West Africa and I had reason to fear I had been exposed to Ebola, do you know what I would do, if I had the resources? I would not wait to see if symptoms appeared or to be diagnosed, I would fly to the US or Europe, where, if symptoms developed, I would receive the very best health care in the world, including experimental treatments, in front of the world’s media.

If I could afford it, even selling everything, I would get on that plane to freedom, or at least a chance. A better chance to live.

But of course along the way, I would expose others to the risk of infection, and I would risk introducing the infection to areas of the world that are currently Ebola-free. It is unlikely, even so, that it would reach the levels seen in West Africa, as these countries have the resources and infrastructure to implement more effective containment strategies. Nevertheless, there is a chance that some people would die.

So how much freedom should people have? Should our freedom to travel be balanced against the risks it might pose to others?

Iterated in vitro reproduction and genetic orphans

In an article soon to be published in the Journal of Medical Ethics, Rob Sparrow imagines a procedure via which multiple generations of human embryos might be created in the laboratory. Egg and sperm cells would first be generated from existing or new human pluripotent stem cell lines. The resulting eggs would be fertilised using the sperm to create zygotes and ultimately embryos. Embryonic stem cells would then be harvested from these embryos and used to create new egg and sperm cells, which would in turn be used to fertilise one another to create further embryos. This process could be iterated, in principle indefinitely.

Let’s call this procedure ‘iterated in vitro reproduction’ (Sparrow calls it ‘in vitro eugenics’). Iterated in vitro reproduction is not yet possible, but, citing recent developments in the science of stem cell-derived gametes, Sparrow argues that it may well become so, though he acknowledges are number of significant hurdles to its development. He also discusses a number of possible applications of the technology and calls for an ethical debate on these. The most controversial application would be in the creation of designer children. Consider the following case, which is a variant on one of the scenarios imagined by Sparrow:

Jack and Jill present to a fertility clinic. Jack provides a sperm sample, and fertility doctors harvest a number of eggs from Jill. These eggs are fertilized with Jack’s sperm to create embryos, from which embryonic stem cells are derived. These stem cells are then induced to develop into eggs or sperm which are used to fertilise one another, and so on. The process is iterated numerous times, and at each stage, the embryos are genetically screened via pre-implantation genetic diagnosis. This screening is used to inform a process of selective crossing, so that, over several generations, the population of embryos evolves towards certain genetic dispositions desired by Jack and Jill (a disposition towards longevity, say). This process is aided by adding small amounts of genetic material from stem cell lines derived from other individuals. Eventually, doctors identify an embryo with almost exactly the desired combination of genes, and this embryo is implanted into Jill’s womb and carried to term. A child, Jarvis, is born.

Cases like this raise numerous ethical issues, some of which are discussed by Sparrow and the seven commentators on his paper. However, they also raise an interesting conceptual question: would the users of such a technology be the genetic parents of the resulting offspring? Would Jack and Jill be the genetic parents of Jarvis?
