ANNOUNCEMENT: Journal of Medical Ethics now accepting longer papers

Please note: this blog is was first published at the Journal of Medical Ethics Blog.

The Journal of Medical Ethics is pleased to announce the addition of a new article type – Extended Essays – that will allow authors up to 7,000 words to provide an in-depth analysis of their chosen topic.

In an interview, Associate Editor Tom Douglas said the new category was created “in recognition of the fact that some topics warrant sustained and nuanced analysis of a sort that can’t be laid out in less than 3,500 words.”

He went on to say that at the Journal of Medical Ethics “we don’t want to miss out on the best papers in medical ethics, many of which currently get sent elsewhere simply because of our strict word limits.”

1 in 4 women: How the latest sexual assault statistics were turned into click bait by the New York Times

by Brian D. Earp / (@briandavidearp)

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


As someone who has worked on college campuses to educate men and women about sexual assault and consent, I have seen the barriers to raising awareness and changing attitudes. Chief among them, in my experience, is a sense of skepticism–especially among college-aged men–that sexual assault is even all that dire of a problem to begin with.

“1 in 4? 1 in 5? Come on, it can’t be that high. That’s just feminist propaganda!”

A lot of the statistics that get thrown around in this area (they seem to think) have more to do with politics and ideology than with careful, dispassionate science. So they often wave away the issue of sexual assault–and won’t engage on issues like affirmative consent.

In my view, these are the men we really need to reach.

A new statistic

So enter the headline from last week’s New York Times coverage of the latest college campus sexual assault survey:

1 in 4 Women Experience Sex Assault on Campus.”

But that’s not what the survey showed. And you don’t have to read all 288 pages of the published report to figure this out (although I did that today just to be sure). The executive summary is all you need.

“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:


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

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


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.

How can journal editors fight bias in polarized scientific communities?

By Brian D. Earp

In a recent issue of the Journal of Medical EthicsThomas Ploug and Søren Holm point out that scientific communities can sometimes get pretty polarized. This happens when two different groups of researchers consistently argue for (more or less) opposite positions on some hot-button empirical issue.

The examples they give are: debates over the merits of breast cancer screening and the advisability of prescribing statins to people at low risk of heart disease. Other examples come easily to mind. The one that pops into my head is the debate over the health benefits vs. risks of male circumcision—which I’ve covered in some detail herehereherehere, and here.

When I first starting writing about this issue, I was pretty “polarized” myself. But I’ve tried to step back over the years to look for middle ground. Once you realize that your arguments are getting too one-sided, it’s hard to go on producing them without making some adjustments. At least, it is without losing credibility — and no small measure of self-respect.

This point will become important later on.

Nota bene! According to Ploug and Holm, disagreement is not the same as polarization. Instead, polarization only happens when researchers:

(1) Begin to self-identify as proponents of a particular position that needs to be strongly defended beyond what is supported by the data, and

(2) Begin to discount arguments and data that would normally be taken as important in a scientific debate.

But wait a minute. Isn’t there something peculiar about point number (1)?

On the one hand, it’s framed in terms of self-identification, so: “I see myself as a proponent of a particular position that needs to be strongly defended.” Ok, that much makes sense. But then it makes it sound like this position-defending has to go “beyond what is supported by the data.”

But who would self-identify as someone who makes inadequately supported arguments?

We might chalk this up to ambiguous phrasing. Maybe the authors mean that (in order for polarization to be diagnosed) researchers have to self-identify as “proponents of a particular position,” while the part about “beyond the data” is what an objective third-party would say about the researchers (even if that’s not what they would say about themselves). It’s hard to know for sure.

But the issue of self-identification is going to come up again in a minute, because I think it poses a big problem for Ploug and Holm’s ultimate proposal for how to combat polarization. To see why, though, I have to say a little bit more about what their overall suggestion is in the first place.

Born this way? How high-tech conversion therapy could undermine gay rights

By Andrew Vierra, Georgia State University and Brian D Earp, University of Oxford

This article was originally published on The Conversation.
Read the 
original article.


Following the death of 17-year-old Leelah Alcorn, a transgender teen who committed suicide after forced “conversion therapy,” President Barack Obama called for a nationwide ban on psychotherapy aimed at changing sexual orientation or gender identity. The administration argued that because conversion therapy causes substantial psychological harm to minors, it is neither medically nor ethically appropriate.

We fully agree with the President and believe that this is a step in the right direction. Of course, in addition to being unsafe as well as ethically unsound, current conversion therapy approaches aren’t actually effective at doing what they claim to do – changing sexual orientation.

But we also worry that this may be a short-term legislative solution to what is really a conceptual problem.

The question we ought to be asking is “what will happen if and when scientists do end up developing safe and effective technologies that can alter sexual orientation?”

Nancy Cartwright on the Limits of RCTs

Guest Post by Bill Gardner @Bill_Gardner

Many researchers and physicians assert that randomized clinical trials (RCTs) are the “gold standard” for evidence about what works in medicine. But many others have pointed to both strengths and limitations in RCTs (see, for example, Austin Frakt’s comments on Angus Deaton here). Nancy Cartwright is a major philosopher of science. In this Lancet paper she provides insights into why RCTs are so highly valued and also why they are by themselves insufficient to answer the most important questions in medicine.

Does religion deserve a place in secular medicine?

By Brian D. Earp

The latest issue of the Journal of Medical Ethics is out, and in it, Professor Nigel Biggar—an Oxford theologian—argues that “religion” should have a place in secular medicine (click here for a link to the article).

Some people will feel a shiver go down their spines—and not only the non-religious. After all, different religions require different things, and sometimes they come to opposite conclusions. So whose religion, exactly, does Professor Biggar have in mind, and what kind of “place” is he trying to make a case for?

On the supposed distinction between culture and religion: A brief comment on Sir James Munby’s decision in the matter of B and G (children)

On the supposed distinction between culture and religion: A brief comment on Sir James Munby’s decision in the matter of B and G (children)

By Brian D. Earp (@briandavidearp)


What is the difference between ‘culture’ and ‘religion’ … ? From a legal standpoint, this question is important: practices which may be described as being ‘religious’ in nature are typically afforded much greater protection from interference by the state than those that are understood as being ‘merely’ cultural. One key area in which this distinction is commonly drawn is with respect to the non-therapeutic alterations of children’s genitals. When such alteration is done to female children, it is often said to be a ‘cultural’ practice that does not deserve legal protection; whereas, when it is done to male children, it is commonly said to be a ‘religious’ practice – at least for some groups – and must therefore not be restricted (much less forbidden) by law.

Is this a valid distinction?

What are the ethics of using brain stimulation technologies for ‘enhancement’ in children?

New open access publication: announcement:

In a recently published article, Hannah Maslen, Roi Cohen Kadosh, Julian Savulescu and I present an argument about the permissible (and not-so-permissible) uses of non-invasive brain stimulation technology in children. We consider both children who may be suffering from a specific neurological disorder, for whom the stimulation is intended as a ‘treatment’, and those who are otherwise healthy, for whom the stimulation is intended as ‘enhancement’. For the full article and citation, see here:
