Climate Ought to Change Politics

Written by Stephen Rainey

In the midst of global climate change set to devastate entire ways of life, and ultimately on track to render the biosphere uninhabitable for all but the most adaptable organisms, it seems timely to question how political legitimacy relates to matters of scientific fact. While it seems mostly desirable that groups of people ought to be self-determining in terms of how they get along with the business of living, there appears to be a limit wherein this principle renders mutual self-determination among groups impossible.

Self-determination among different groups in some sense generates contradictory demands. Especially where limited resources are a factor, not everyone can successfully pursue their own ends, which generates tensions between groups. Among the limits that prompt such mutually challenging ways of life are the kinds of facts discovered in scientific research. We know from trends observable by climate scientists that patterns of living currently enjoyed by many are unsustainable and are causing damage to the possibility of continued living on Earth. Yet this is known in a rather strange way. Continue reading

Gene-Editing Mosquitoes at The European Youth Event 2018

By Jonathan Pugh

 

The below is a slightly extended version of my two 5min presentations at the European Youth Event 2018, at the European Parliament in Strasbourg. I was asked to present on the following questions:

 

  1. What are the ethical issues surrounding gene-editing, particularly with respect to eradicating mosquitoes?

 

  1. Should the EU legislate on gene-editing mosquitoes?

Guest Post: Consequentialism and Ethics? Bridging the Normative Gap.

Written by Simon Beard

University of Cambridge

After years of deliberation, a US moratorium on so-called ‘gain of function’ experiments, involving the production of novel pathogens with a high degree of pandemic potential, has been lifted [https://www.nih.gov/about-nih/who-we-are/nih-director/statements/nih-lifts-funding-pause-gain-function-research]. At the same time, a ground-breaking new set of guidelines about how and when such experiments can be funded has been published [https://thebulletin.org/new-pathogen-research-rules-gain-function-loss-clarity11540] by the National Institutes of Health. This is to be welcomed, and I hope that these guidelines stimulate broader discussions about the ethics and funding of duel use scientific research, both inside and outside of the life sciences. At the very least, it is essential that people learn from this experience and do not engage in the kind of intellectual head banging that has undermined important research, and disrupted the careers of talented researchers.

Yet, there is something in these guidelines that many philosophers may find troubling.

These new guidelines insist, for the first time it seems, that NIH funding will depend not only on the benefits of scientific research outweighing the potential risks, but also on whether or not the research is “ethically justified”. In defining what is ethically justifiable, the NIH make specific reference to standards of beneficence, non-maleficence, justice, scientific freedom, respect for persons and responsible stewardship.

Much has been made of this additional dimension of evaluation and whether or not review committees will be up to assessing it. Whereas before, it is said, they merely had to assess whether research would have good or bad outcomes, they now have to determine whether it is right or wrong as well! Continue reading

Neuroblame?

Written by Stephen Rainey

Brain-machine interfaces (BMIs), or brain-computer interfaces (BCIs), are technologies controlled directly by the brain. They are increasingly well known in terms of therapeutic contexts. We have probably all seen the remarkable advances in prosthetic limbs that can be controlled directly by the brain. Brain-controlled legs, arms, and hands allow natural-like mobility to be restored where limbs had been lost. Neuroprosthetic devices connected directly to the brain allow communication to be restored in cases where linguistic ability is impaired or missing.

It is often said that such devices are controlled ‘by thoughts’. This isn’t strictly true, as it is the brain that the devices read, not the mind. In a sense, unnatural patterns of neural activity must be realised to trigger and control devices. Producing the patterns is a learned behaviour – the brain is put to use by the device owner in order to operate it. This distinction between thought-reading and brain-reading might have important consequences for some conceivable scenarios. To think these through, we’ll indulge in a little bit of ‘science fiction prototyping’.

Guest Post: Crispr Craze and Crispr Cares

Written by Robert Ranisch, Institute for Ethics and History of Medicine, University of Tuebingen

@RobRanisch

Newly discovered tools for the targeted editing of the genome have been generating talk of a revolution in gene technology for the last five years. The CRISPR/Cas9-method draws most of the attention by enabling a more simple and precise, cheaper and quicker modification of genes in a hitherto unknown measure. Since these so-called molecular scissors can be set to work in just about all organisms, hardly a week goes by without headlines regarding the latest scientific research: Genome editing could keep vegetables looking fresh, eliminate malaria from disease-carrying mosquitoes, replace antibiotics or bring mammoths back to life.

Naturally, the greatest hopes are put into its potential for various medical applications. Despite the media hype, there are no ready-to-use CRISPR gene therapies. However, the first clinical studies are under way in China and have been approved in the USA. Future therapy methods might allow eradicating hereditary illnesses, conquering cancer, or even cure HIV/AIDS. Just this May, results from experiments on mice gave reason to hope for this. In a similar vein, germline intervention is being reconsidered as a realistic option now, although it had long been considered taboo because of how its (side)effects are passed down the generations.

Cross Post: What do sugar and climate change have in common? Misplaced scepticism of the science

Written by Professor Neil Levy, Senior Research Fellow, Uehiro Centre for Practical Ethics, University of Oxford

Why do we think that climate sceptics are irrational? A major reason is that almost none of them have any genuine expertise in climate science (most have no scientific expertise at all), yet they’re confident that they know better than the scientists. Science is hard. Seeing patterns in noisy data requires statistical expertise, for instance. Climate data is very noisy: we shouldn’t rely on common sense to analyse it. We are instead forced to use the assessment of experts. Continue reading

Guest Post: Scientists aren’t always the best people to evaluate the risks of scientific research

Written by Simon Beard, Research Associate at the Center for the Study of Existential Risk, University of Cambridge

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.

Guest Post: ENHANCING WISDOM

Written by Darlei Dall’Agnol[1]

Stephen Hawking has recently made two very strong declarations:

  • Philosophy is dead;
  • Artificial intelligence could spell the end of the human race.

I wonder whether there is a close connection between the two. In fact, I believe that the second will be true only if the first is. But philosophy is not dead and it may undoubtedly help us to prevent the catastrophic consequences of misusing science and technology. Thus, I will argue that it is through the enhancement of our wisdom that we can hope to avoid artificial intelligence (AI) causing the end of mankind.  Continue reading

“The medicalization of love” – podcast interview

Just out today is a podcast interview for Smart Drug Smarts between host Jesse Lawler and interviewee Brian D. Earp on “The Medicalization of Love” (title taken from a recent paper with Anders Sandberg and Julian Savulescu, available from the Cambridge Quarterly of Healthcare Ethics, here).

Below is the abstract and link to the interview:

Abstract

What is love? A loaded question with the potential to lead us down multiple rabbit holes (and, if you grew up in the 90s, evoke memories of the Haddaway song). In episode #95, Jesse welcomes Brian D. Earp on board for a thought-provoking conversation about the possibilities and ethics of making biochemical tweaks to this most celebrated of human emotions. With a topic like “manipulating love,” the discussion moves between the realms of neuroscience, psychology and transhumanist philosophy.

Psychology is not in crisis? Depends on what you mean by “crisis”

By Brian D. Earp
@briandavidearp

*Note that this article was originally published at the Huffington Post.

Introduction

In the New York Times yesterday, psychologist Lisa Feldman Barrett argues that “Psychology is Not in Crisis.” She is responding to the results of a large-scale initiative called the Reproducibility Project, published in Science magazine, which appeared to show that the findings from over 60 percent of a sample of 100 psychology studies did not hold up when independent labs attempted to replicate them.

She argues that “the failure to replicate is not a cause for alarm; in fact, it is a normal part of how science works.” To illustrate this point, she gives us the following scenario:

Suppose you have two well-designed, carefully run studies, A and B, that investigate the same phenomenon. They perform what appear to be identical experiments, and yet they reach opposite conclusions. Study A produces the predicted phenomenon, whereas Study B does not. We have a failure to replicate.

Does this mean that the phenomenon in question is necessarily illusory? Absolutely not. If the studies were well designed and executed, it is more likely that the phenomenon from Study A is true only under certain conditions. The scientist’s job now is to figure out what those conditions are, in order to form new and better hypotheses to test.

She’s making a pretty big assumption here, which is that the studies we’re interested in are “well-designed” and “carefully run.” But a major reason for the so-called “crisis” in psychology — and I’ll come back to the question of just what kind of crisis we’re really talking about (see my title) — is the fact that a very large number of not-well-designed, and not-carefully-run studies have been making it through peer review for decades.

Small sample sizes, sketchy statistical procedures, incomplete reporting of experiments, and so on, have been pretty convincingly shown to be widespread in the field of psychology (and in other fields as well), leading to the publication of a resource-wastingly large percentage of “false positives” (read: statistical noise that happens to look like a real result) in the literature.
