It has long been known that cognitive diversity is important to collective performance. Diverse groups are more productive, more innovative and better at solving complex problems than less diverse groups. And recent research suggests that cognitive diversity also drives scientific progress.
Such research has direct implications for how we regulate reproductive technologies. Late last year, the London Sperm Bank was criticised for its decision to ban sperm donors who suffer from minor neurological disorders, including dyslexia and Asperger’s syndrome. Continue reading
Associate Professor and Consultant Neonatologist Dominic Wilkinson (Oxford Uehiro Centre for Practical Ethics) argues that medical doctors should not always listen to their own conscience and that often they should do what the patient requests, even when this conflicts with their own values.
A trial to see if it is possible to regenerate brains in patients that have been declared clinically dead has been approved. Reanima Advanced Biosciences aims at using stem cells, injections of peptides, and nerve stimulation to cause regeneration in brain dead patients. The primary outcome measure is “reversal of brain death as noted in clinical examination or EEG”, which at least scores high on ambition. The study accepts healthy volunteers, but they need to be brain dead due to traumatic brain injury, which might discourage most people.
Is there any problem with this? Continue reading

How can we study the pathogens that will be responsible for future global pandemics before they have happened? One way is to find likely candidates currently in the wild and genetically engineer them so that they gain the traits that will be necessary for them to cause a global pandemic.
Such ‘Gain of Function’ research that produces ‘Potential Pandemic Pathogens’ (GOF-PPP for short) is highly controversial. Following some initial trails looking at what kinds of mutations were needed to make avian influenza transmissible in ferrets, a moratorium has been imposed on further research whilst the risks and benefits associated with it are investigated.

Asbestos kills more people per year than excessive sun exposure, yet it receives much less attention. Tom Douglas (Oxford Uehiro Centre for Practical Ethics) explains why asbestos is still a serious public health threat and what steps should be undertaken to reduce this threat. And yes, the snow in The Wizard of Oz was asbestos!
“Cognitive Enhancement: Defending the Parity Principle”, St Cross Special Ethics Seminar by Neil Levy
Last Thursday Professor Neil Levy has defended his Parity Principle for analysing the ethics of cognitive enhancement at the St Cross Special Ethics Seminar. Such principle would oppose a common form of objection against enhancement which claims that there is a worrying asymmetry between enhancement and traditional means to human improvement. Conversely, Neil contends that the function is all that matters morally when comparing enhancement with traditional means and that comparing isofunctional modifications reveals that there are little unique problems with enhancement. The Parity Principle leads to a useful analysis of several proposed critiques of cognitive enhancement. Continue reading
Everyone I know thinks it’s obscene, and that the suffering of the dogs cannot possibly be outweighed by the sensual satisfaction of the diners, the desirability of not interfering, colonially, with practices acceptable in another culture, or by any other consideration. It’s just wrong.
‘It’s just wrong’ is the observation that moral philosophers exist to denounce. They draw their salaries for interrogating this observation, exploding its naivety, and showing that the unexamined observation is the observation not worth making.
But what can the moral philosophers bring to the discussion about the Chinese dogs? Alone, and unaided by science, not much. The philosophy turns out to be either (a) reheated science or (b) a description of our intuitions, together with more or less bare assertions that those intuitions are either good or bad.

Science and medicine have done a lot for the world. Diseases have been eradicated, rockets have been sent to the moon, and convincing, causal explanations have been given for a whole range of formerly inscrutable phenomena. Notwithstanding recent concerns about sloppy research, small sample sizes, and challenges in replicating major findings—concerns I share and which I have written about at length — I still believe that the scientific method is the best available tool for getting at empirical truth. Or to put it a slightly different way (if I may paraphrase Winston Churchill’s famous remark about democracy): it is perhaps the worst tool, except for all the rest.
Scientists are people too
In other words, science is flawed. And scientists are people too. While it is true that most scientists — at least the ones I know and work with — are hell-bent on getting things right, they are not therefore immune from human foibles. If they want to keep their jobs, at least, they must contend with a perverse “publish or perish” incentive structure that tends to reward flashy findings and high-volume “productivity” over painstaking, reliable research. On top of that, they have reputations to defend, egos to protect, and grants to pursue. They get tired. They get overwhelmed. They don’t always check their references, or even read what they cite. They have cognitive and emotional limitations, not to mention biases, like everyone else.
At the same time, as the psychologist Gary Marcus has recently put it, “it is facile to dismiss science itself. The most careful scientists, and the best science journalists, realize that all science is provisional. There will always be things that we haven’t figured out yet, and even some that we get wrong.” But science is not just about conclusions, he argues, which are occasionally (or even frequently) incorrect. Instead, “It’s about a methodology for investigation, which includes, at its core, a relentless drive towards questioning that which came before.” You can both “love science,” he concludes, “and question it.”
I agree with Marcus. In fact, I agree with him so much that I would like to go a step further: if you love science, you had better question it, and question it well, so it can live up to its potential.
And it is with that in mind that I bring up the subject of bullshit.
Every day, for about thirty-five minutes, I sit cross-legged on a cushion with my eyes shut. I regulate my breath, titrating its speed against numbers in my head; I watch my breath surging and trickling in and out of my chest; I feel the air at the point of entry and exit; I export my mind to a point just beyond my nose and pour the breath into that point. When my mind wanders off, I tug it back.
The practice is systematic and arduous. In some ways it is complex: it involves 16 distinct stages. When I am tired, and the errant mind won’t come quietly back on track, I find it helpful to summarise the injunctions to myself as:
- I am here
- This is it
I alternate the emphases: ‘I am here’: ‘I am here’; ‘I am here’; ‘This is it’; ‘This is it’; ‘This is it.’
I note (although not usually, and not ideally, when I’m in the middle of the practice) that each of these connotations presumes something about the existence of an ‘I’. This is less obvious with the second proposition, but clearly there: ‘This’ is something that requires a subject. Continue reading
