Where are my smart genes? Searching for intelligence in our DNA

Where are my smart genes? Searching for intelligence in our DNA

Reproductive technologies such as in-vitro fertilization (IVF) and preimplantation genetic diagnosis (PGD) mean it is currently possible for parents to create a range of embryos and make decisions about which to implant on the basis of their genetic makeup.  One interesting possibility is that we will soon be able to use such technologies to influence the intelligence of our future children. It is known that intelligence has at least a moderately important genetic component. Identical twins are significantly more similar in intelligence than dizygotic twins, who are in turn significantly more similar than adopted siblings raised together. In fact, a range of studies indicate that the heritability of intelligence is approximately 0.7, which is only slightly lower than the heritability of height. This means that 70% of the variation we observe in intelligence is due to genetic factors. Once we can identify the genes which explain this variation it will be relatively simple to test embryos for them, meaning it will be technically possible for parents to select embryos on the basis of their likely intelligence.

However scientists are finding it surprisingly difficult to locate the specific genes which affect intelligence. Read More »Where are my smart genes? Searching for intelligence in our DNA

Back to the Future: The Ethics of Cloning Neanderthals and Creating Genetically Modified Animals

“George Church, a genetics professor of Harvard School of Medicine, said that the process was possible and that far from being brutal and primitive, Neanderthals were intelligent beings.

They are believed to be one of the ancestors of modern man and became extinct 33,000 years ago. He added that altering the human genome could also provide the answers to curing diseases such as cancer and HIV, and hold the key to living to 120.

He told Der Spiegel, the German magazine: “I have already managed to attract enough DNA from fossil bones to reconstruct the DNA of the human species largely extinct. Now I need an adventurous female human.”

The professor claims that he could introduce parts of the Neanderthal genome to human stem cells and clone them to create a foetus that could then be implanted in a woman.”

From The Telegraph 

This would be illegal in the UK and many other parts of the world. But is it morally wrong?

Pedophilia, Preemptive Imprisonment, and the Ethics of Predisposition

The first two weeks of 2013 were marked by a flurry of news articles considering “the new science” of pedophilia. Alan Zarembo’s article for the Los Angeles Times focused on the increasing consensus among researchers that pedophilia is a biological predisposition similar to heterosexuality or homosexuality. Rachel Aviv’s piece for The New Yorker shed light upon the practice of ‘civil commitment’ in the US, a process by which inmates may be kept in jail past their release date if a panel decides that they are at risk of molesting a child (even if there is no evidence that they have in the past). The Guardian’s Jon Henley quoted sources suggesting that perhaps some pedophilic relationships aren’t all that harmful after all. And Rush Limbaugh chimed in comparing the ‘normalization’ of pedophilia to the historical increase in the acceptance of homosexuality, suggesting that recognizing pedophilia as a sexual orientation would be tantamount to condoning child molestation.

So what does it all mean? While most people I talked to in the wake of these stories (I include myself) were fascinated by the novel scientific evidence and the compelling profiles of self-described pedophiles presented in these articles, we all seemed to have a difficult time wrapping our minds around the ethical considerations at play. Why does it matter for our moral appraisal of pedophiles whether pedophilia is innate or acquired? Is it wrong to imprison someone for a terrible crime that they have not yet committed but are at a “high risk” of committing in the future? And if we say that we can’t “blame” pedophiles for their attraction to children because it is not their “fault” – they were “born this way” – is it problematic to condemn individuals for acting upon these (and other harmful) desires if it can be shown that poor impulse control is similarly genetically predisposed? While I don’t get around to fully answering most of these questions in the following post, my aim is to tease out the highly interrelated issues underlying these questions with the goal of working towards a framework by which the moral landscape of pedophilia can be understood. Read More »Pedophilia, Preemptive Imprisonment, and the Ethics of Predisposition

Enlightened surveillance?

New York City contemplates using aerial drones for surveillance purposes, while North Korea buys thousands of cameras to spy on its impoverished population. Britain has so many cameras they cease being newsworthy. The stories multiply – it is trivial to note we are moving towards a surveillance society.

In an earlier post, I suggested surrendering on surveillance might be the least bad option – of all likely civil liberty encroachments,  this seemed the less damaging and hardest to resist. But that’s an overly defensive way of phrasing it – if ubiquitous surveillance and lack of privacy are the trends of the future, we shouldn’t just begrudgingly accept them, but demand that society gets the most possible out of them. In this post, I’m not going to suggest how to achieve enlightened surveillance (a 360 degree surveillance would be a small start, for instance), but just outline some of the positive good we could get from it. We all know the negatives; but what good could come from corporations, governments and neighbours being able to peer continually into your bedroom (and efficiently process that data)? In the ideal case, how could we make it work for us?Read More »Enlightened surveillance?

Amnesia and remorse: how much should we expect?

Photograph: Filip Klimaszewski / Agencja Gazeta

When people do bad things – especially when they cause a lot of harm to others – we usually hope that they will experience something like remorse: that they will feel horror at the thought of what they did to the person harmed, that they will resolve to avoid causing similar harm in the future, and that they will be motivated to apologise and offer reparation, where possible. Penal systems in some jurisdictions deem remorse so important that it is considered a valid reason to mitigate the amount of punishment the offender receives. But, what happens to our expectations for emotion if the person cannot remember committing the offence; if he feels so detached from it that it is as if he did not commit it? An interesting case from Poland raises this question.

Maciej Zientarski was a celebrity driver on a TV programme similar to our Top Gear. On the 27th February 2008, accompanied by his motor journalist friend, he was given a Ferrari to test drive. The test drive didn’t end well. CCTV cameras captured footage of the car being driven at speeds of between 140-150kph along a 50kph road, serial over-taking, and the eventual head-on smash into the pillar of a bridge above. The motor journalist died at the scene but the driver, remarkably, just about survived. Read More »Amnesia and remorse: how much should we expect?

Invoking and banishing the dread demon “Lead”

Some researchers have fingered a surprising culprit for the crime wave that ended in the 1990s: lead, mainly from leaded fuel. We know that lead leads to development difficulties in children, and in country after country, lead emissions closely mirror the crime rate 23 years later – after those children have grown up into mature, irresponsible… Read More »Invoking and banishing the dread demon “Lead”

More theory needed: why things work

We have a lot of good theories as to why government policies don’t work. Regulatory capture explains why regulating agencies cosy up to the industries they’re suppose to reign in. Politicians’ relentless focus on short term economic growth and desperate chasing of positive headlines causes them to embrace ill-advised short-term measures (and forget about action on things like climate change!). Meanwhile, the civil service’s tenure and lack of accountability allows it to indulge in exuberant nest-feathering wastes of taxpayers’ money. Issues of status and pride saturate the decisions of all ranks of government officials.

These theories are not only intuitive, they are also backed up by research and evidence. And yet…

Armstrong Confesses: What Now?

On the eve of his confession, Armstrong is apparently ruined. The International Cycling Union (UCI) has stripped Lance Armstrong of his titles. Sponsors and Tour organisers want millions of dollars returned. UCI president Pat McQuaid said, “Lance Armstrong has no place in cycling. He deserves to be forgotten.” But doping will always be present in… Read More »Armstrong Confesses: What Now?

Abortion and the cognitively impaired mother

It will be interesting to watch the reception of a recent Court of Protection case, as yet unreported, in which a woman with profound learning difficulties was found to have capacity to decide not to terminate her pregnancy.

As so often, the case decided nothing new. But it is a timely reminder of the trite but often overlooked principle that capacity is not an all or nothing thing. The question: ‘Does she have capacity?’ is always dangerously incomplete. The correct question is always ‘Does she have capacity to decide X?’

There was no doubt that she did not have capacity to manage many aspects of her affairs. She was in the bottom 1% of the population so far as intellectual function was concerned. Deputies were appropriately appointed. But, so far as the continuation of her pregnancy was concerned, so what?

It was decided as a matter of fact that she had capacity to decide whether or not to continue with, or to terminate, the pregnancy. And that meant that the Court of Protection had no jurisdiction to decide the matter. No best interests determination could lawfully be made.Read More »Abortion and the cognitively impaired mother
