Opinions, evidence, and anti-research agendas: A recap of a session at the American Society of Primatologists/International Primatological Society Meeting 2016

Research with nonhuman primates in laboratory settings is a tiny fraction of both laboratory research and nonhuman primate research. The topic is of disproportionate interest, however, for many reasons, and is reflected by a recent symposium at the joint meeting of The American Society of Primatologists and International Primatological Society. The session was titled “Use and care of captive non-human primates: Evaluating and improving ethical requirements.”  The session was notable for a number of reasons.

  • Despite its inclusion in the scientific program of scientific societies, the session presented little evidence and little balance.
  • The panelists were tied to organizations and/or campaigns opposed to laboratory research with nonhuman primates, yet did not disclose these ties upfront and failed to provide their basic starting assumptions or to acknowledge their positions.
  • The fact-less rhetoric did not provide a basis for productive discussion about captive primate care or changes to existing regulations, as would have been provided with evidence-based presentations.

Starting assumptions

We wrote yesterday about why providing basic starting assumptions is key when entering any dialogue, particularly when that dialogue involves conversations about the ethical and moral considerations related to the use of animals in biomedical research. If basic starting assumptions are not put forth at the start of a dialogue, then potential areas for agreement cannot be identified – if they in fact exist at all.

Unfortunately, this tenet was not practiced during the symposium. The organizers, anthropologists Drs. Barbara J. King and Marni M. LaFleur, wrote that the symposium was intended to“invite IPS and ASP members to come together and discuss how we may best manage the care and oversight of captive-living nonhuman primates.” At face value, this invitation seemed like a safe haven for “discussion and collaboration amongst researchers, veterinarians, technicians, and caregivers.” (In fact, data-driven sessions like these occur regularly at ASP meetings amongst the experts who care for and study captive primates.) However, the organizers and panelists failed to disclose their basic assumptions upfront, namely that they oppose the use of nonhuman primates in biomedical research.

Several speakers in the symposium have affiliated with campaigns by PETA, an organization that very clearly offers an absolutist position stating that animals should never be experimented on. The Vice President of Animal Research Issues at the Humane Society of the United States (HSUS), Kathleen Conlee, was also featured. HSUS’ position is less clear, though one of Conlee’s slides stated that the organization’s aim is to “Promote 3R’s but push for replacement of invasive research as quickly as possible.”

As many attendees of the session attested after it concluded, the panelists’ failure to establish positions upfront resulted in a session with a very narrow focus that did not actually result in constructive discussion. Although the speakers’ stances on biomedical research were not stated upfront, they became readily apparent in each presentation.

The symposium followed a roundtable format, with the 6 speakers each presenting for about 5 minutes and a Q&A session for about an hour and a half afterward. Notably, the speakers did not include information on the well-established regulations and processes that are in place to balance research objectives, animal welfare, and public interests in scientific advances. (In 2015, ASP held a roundtable that thoroughly addressed these topics with evidence-based material.) Some presenters did show historical timelines of a few pieces of legislation enacted to address and ensure animal welfare (e.g., the passage of and amendments to the Animal Welfare Act), though nearly all presentations were lacking in evidence-based arguments. Instead, they often relied on outdated and out-of-context photographs (some from undercover investigations, which Conlee proudly acknowledged to the audience that HSUS had undertaken). Granted, the 5-minute time-slot for each speaker precluded the ability to delve into details, but one has to wonder if this format was a means to deliberately exclude the evidence-based regulations and processes that exist for laboratory animals.

Who should evaluate primate research?

The first speaker, LaFleur, wrote in the abstract of her presentation: “Ethical standards and cost-benefit analyses of non-human primates in research must continually be evaluated and reevaluated, by a diverse range of experts (including those without vested interests).” By “vested interests,” LaFleur presumably meant those working in primate research. What wasn’t clear is whether the panelists believe that they themselves and organizations such as PETA and HSUS also have clearly vested interests. For example, PETA has an extremely vested interests in this issue, yet nowhere during the session was it disclosed that panelist King has worked actively on campaigns organized by PETA (for other panelists’ ties to PETA; see below).

Most important though, from the perspective of beginning with fact:  The analyses of non-human primates in research to which LaFleur refers already routinely occurs by experts in the field: the trained scientists, veterinarians, and colony managers, including many members of ASP, who work with primates in captive settings on a daily basis and dedicate much of their research programs toward understanding and improving their welfare (see, for one recent example, this special issue of the American Journal of Primatology, dedicated solely to the well-being of laboratory nonhuman primates).

LaFleur also wrote in her abstract, “I argue that experimental procedures which cause permanent and irreversible harm on individual non-human primates should not be deemed ethically permissible.”

Yet, LaFleur failed to make a clear case for exactly why her position is justified in a way that is more appropriate than the position held by others who were part of the multi-level review that weighs scientific objectives and animal welfare and grants approval for research projects.

Furthermore, the slides that LaFleur presented at the conference showed data-free descriptions not of experimental procedures broadly, but of a single research topic. Her focus was on studies of infant development in monkeys (work she termed “maternal deprivation”) at the NIH and the criticism that she, King, and others leveled at ASP in regards to the society’s open support for research at the NIH. For example, in one of her slides, LaFleur stated that 54 members of ASP had signed a letter she co-authored to ASP asking for a reconsideration of their support letter for an NIH research project. In fact, in reading through the list of signatories, it is not at all clear to long-time members of ASP whether many of the signatories had ever been members of the society. One must question why this misinformation was presented at such a large meeting and also why this single research topic was the focus.

Another slide asked the question, “Can we not have differing opinions from our friends and colleagues?” Of course differing opinions may exist. What we strive for, however, are regulations and policies that are based in scientific evidence in order to provide for animal health and well-being. In the context of dialogue and the supposed focus on the symposium, the larger question is whether focusing on differing opinions about one research project and one area of study is a good substitute for serious and thoughtful consideration to identify core principles that can guide continuing changes in practice and policy.

Dr. Stacy Lopresti-Goodman came closest to laying out her basic assumptions upfront in her abstract, in which she wrote, “the primate research community should consider whether retirement of all NHP from biomedical research to sanctuary is warranted.” Lopresti-Goodman provided a few slides that cited research studies to back her written statement that “many individuals who experience…adverse conditions exhibit abnormal and/or stereotypic behaviors, and develop symptoms of psychological distress that mirror those of psychopathology in humans,” though it is notable that she did not disclose at any time during the session that she has co-authored articles with PETA employees and others staunchly opposed to animal research.

Moreover, several in the audience questioned her direct knowledge, experience, and expertise on the topic given her training and publication record in human perception and cognition.


Evaluating a claim from HSUS:  What is the evidence on environmental enrichment for nonhuman primates in captive settings?

In the US, all facilities registered or licensed to house nonhuman primates by the federal agency charged with oversight and enforcement of the Animal Welfare Act (AWA) are required to have a plan for environmental enrichment for those animals. Evidence-based evaluation of practices aimed at meeting the goal of maintaining animals’ health and well-being, in balance with scientific objectives, is the subject of research by many ASP members and those scientific results are on display at most ASP meetings.  The findings inform practices across the range of settings in which nonhuman primates live in captivity.

Conlee’s symposium presentation took a very narrow view, focusing on an analysis that her organization (HSUS) completed of enrichment plans from 38 universities and 18 federal facilities. Those plans were obtained, in part, via use of open records laws. The analysis was aimed at evaluating whether the plans were compliant with federal law. The abstract made a startling claim:  “Plans were scored according to compliance with the minimum Animal Welfare Act standards … The analysis revealed a majority of plans (44) were not adequate.”  To be clear, what that claim suggests is that 44% of the facilities — facilities that are regularly inspected by a federal agency, the USDA– are failing to comply with federal law.

Serious claim – can it be evaluated?  Unfortunately, not well.  The analysis is unpublished and unavailable for public view or critique. Conlee provided no details about the methodology, including critical definitions of coding schemes for “plans [that] were scored according to compliance with the minimum Animal Welfare Act standards” and the subsequent data analysis.

The results Conlee presented were confined to bullet points on one slide rather than actual data with accompanying statistical analysis. Collectively, the “study” did not meet ASP’s (and other societies’) criteria for scientific presentations, but was nonetheless was presented as though it were an empirical study. While that is disappointing enough, the fact that the presentation and abstract made serious claims potentially misrepresenting a large number of dedicated research centers is even more reason to hold presenters to a standard of evidence.

Finally, Conlee presented a slide stating, “USDA requirements for all regulated facilities: no change in 30 years.” However, this statement is misleading. As Justin McNulty, IACUC & IBC Manager at The University of Texas at Austin, pointed out in the discussion following the presentations, “The Guide for the Care and Use of Laboratory Animals was just revised in 2011 and was reviewed by some of the people in this room. The recommendations contained in the Guide were based on published data, scientific principles, and expert opinion.” As described in the preface to the 8th Edition of The Guide, “The Guide is intended to assist investigators in fulfilling their obligation to plan and conduct animal experiments in accord with the highest scientific, humane, and ethical principle.”

Lack of evidence for the benefit-risk ratio in laboratory primate research?

LaFleur also gave King’s presentation in her absence. In her written abstract, King wrote, “I will discuss case studies that are lab-based and involve maternal-deprivation and other invasive experiments on cercopithecines; peer-reviewed scientific material from both the cercopithecine and also the comparative chimpanzee literature will provide context for discussing the benefit-harm ratio of such research on monkeys.” However, this presentation also lacked evidence-based claims and relied on references from the news media, as in one slide that touted the primate facilities that closed, or are in the process of phasing out, in 2015. In giving the presentation, LaFleur incorrectly stated that, with respect to the phasing out of the NICHD’s primate research, “those 300 monkeys [were] from the maternal deprivation work.”  This is false: only a small percentage of the colony at this facility each year has undergone nursery-rearing. Furthermore, as noted above, the actual process in place for evaluating balance of potential benefit and scientific objectives with animal welfare was not well addressed by the panelists.


Collectively, the session left much to be desired for those seeking data-driven suggestions for improving the captive care of non-human primates. As Dr. Karen Hambright, Professor of Psychology at the College of Coastal Georgia and long-time ASP member, stated during the discussion period, “As an educator who has worked with and is familiar with the conditions of animals in both zoos and labs, it my job to teach people to think critically and to base their views on evidence and not on emotional responses to polarizing rhetoric.”

King and LaFleur’s symposium abstract ended with the question, “How specifically can productive discussion about ethics be furthered among primatologists who work primarily on lab science and primatologists who work primarily on animal welfare, always acknowledging that these two groups may overlap?” A good start would be to enact practices that are foundational to any honest dialogue: namely, spelling out basic positions upfront and disclosing any potential conflicts of interest. Productive discussion could then ensue with evidence-based comments and suggestions.

Confusing public agendas: Is it animal welfare? Or an absolutist campaign disguised as a call for “dialogue”?

A recent symposium at the joint meeting of The American Society of Primatologists and International Society of Primatologists focused on questions about the oversight and regulation of the housing, care, and treatment of nonhuman primates in research. Presentations of scientific research that primatologists conduct in order to inform animal care practices are a regular occurrence at ASP. This session, however, was billed as a call for dialogue. The organizers and participants included affiliates of groups and campaigns, including HSUS and PETA, that are often opposed to many types of primate research. ASP and ISP members conduct primate research in field, laboratory, zoo, and other settings across the world. The focus of this conference session appeared to be largely on laboratory  research, and particularly, that work funded by the US federal agency—the National Institutes of Health—that is charged with scientific research relevant to advancing public health.

Such research is a popular target for PETA and other groups opposed to the use of nonhuman animals in research, yet it remains a fact that the great majority of US facilities that house nonhuman primates are not dedicated research facilities (see graphic; summary illustration of data from USDA). As shown here, of the just over 1,000 US facilities that are either USDA-registered for research or USDA-licensed to house nonhuman primates for other purposes,  roughly 1/5th hold research registration. The majority are exhibitors. That includes zoos and other facilities that display animals to the public or engage in public interaction with the animals. In the US, the number of primates housed within each facility is reported annually for research institutions and is published by the USDA (for example, see here); however, the number of primates housed in licensed facilities is not easily accessible. This is similar to other countries.

We’ve written previously about the standards of care, external oversight, and public transparency of federally-funded research within dedicated research facilities in comparison to zoos, sanctuaries, breeders, dealers, and private owners of nonhuman primates (Bennett & Panicker, 2016). In fact, some of these comparisons are central to discussions in recent months about decisions to ensure the best outcomes and long-term care of retired chimpanzees (1, 2, 3, 4, 5).

The limited focus of the recent ASP/ISP conference session to nonhuman primates used in research in the US (18% of facilities) could have many explanations. We will return to consideration of these points, and to a fuller discussion of the session, in subsequent posts. To begin, however, we return to excerpts from a post we made in 2013, with points that are foundational and key to a fair dialogue.

Fair partners in dialogue: Starting assumptions matter and they should be spelled out

The importance and need for civil, open dialogue about the complex set of issues involved in use of animals is among the points of agreement between members of the scientific community, the public, animal rights activists, and others. Speaking of Research, along with others, has consistently advocated for and engaged in such dialogue via a number of venues, including our blog, public events, conference presentations, and articles.

One of the important purposes of dialogue is to communicate diverse viewpoints and values on animal research and one key to understanding those viewpoints and values is consideration of the basic starting assumptions, or positions, from which they arise. However, such dialogue often takes place without clear specification of the starting positions held by the people engaged in the conversation. Speaking of Research has previously highlighted the problem with this approach– for example, see Prof. Dario Ringach’s posts on a series of public forums on ethics and animal research (here, here, here).

The basic position of those engaged in animal research is obvious in part by the nature of their work. Furthermore, the very structure of the current regulations and practices reflect– both implicitly and explicitly – a set of positions on the ethical and moral considerations relevant to the use of animals in research (*see below).

What are the positions of those who oppose laboratory animal research?

In some cases, these are clearly stated. In the case of absolutists, the position is that no matter what potential benefit the work may result in, no use of animals is morally justified. This extends across all animals – from fruit-fly to primate. Furthermore, all uses of animals, regardless of whether there are alternatives and regardless of the need, are treated identically. In other words, the use of a mouse in research aimed at new discoveries to treat childhood disease is considered morally equivalent to the use of a cow to produce hamburger, the use of an elephant in a circus, or a mink for a fur coat.

In this framework, the focus often excludes consideration of the harms that would accrue as a consequence of enacting the animal rights agenda. For example, the harm to both humans and other animals of foregoing research or intervening on behalf of animals. As a result, while the absolutist position is often represented as one that involves only benefits and no harms, this is a false representation. While some animal rights groups are clear about their absolutist position, others—to our knowledge—are not.

On the other hand are those who avoid identifying directly with an absolutist position, but instead focus on the need for development of alternatives to use of animals in invasive research. This is a goal that may be widely desired and shared. It does not, however, address the question of what should be done in absence of alternatives and in light of current needs that can only be addressed by animal studies. In turn then, this position is silent with respect to moral and ethical consideration of a broad swath of research and fails to offer a framework to guide current actions.

We believe that the goal of promoting better dialogue would be assisted by making these positions clear and we provide a starting place below. We welcome additions by individuals and groups, as well as clarification or correction if any are unintentionally misrepresented. (For additional groups see original post).

People for the Ethical Treatment of Animals: Offers clear statement of absolutist position. “PETA has always been known for uncompromising, unwavering views on animal rights. PETA was founded in 1980 and is dedicated to establishing and defending the rights of all animals. PETA operates under the simple principle that animals are not ours to eat, wear, experiment on, or use for entertainment.”

New England Anti-Vivisection Society: Offers clear statement of absolutist position. “Is NEAVS against all animal experiments? Yes. For ethical, economic and scientific reasons, NEAVS is unequivocally opposed to all experiments on animals and works to replace them with humane and scientifically superior alternatives that are more relevant and predictive for humans.”

Humane Society of the United States (HSUS): Does not, to our knowledge, offer a clear position on whether it is morally acceptable to use animals in research when there is no alternative. What they do say: “As do most scientists, The HSUS advocates an end to the use of animals in research and testing that is harmful to the animals. Accordingly, we strive to decrease and eventually eliminate harm to animals used for these purposes.”

Physicians Committee for Responsible Medicine (PCRM/Physicians Committee): Does not, to our knowledge, offer a clear position on whether it is morally acceptable to use animals in research when there is no alternative. What they do say: “We promote alternatives to animal research and animal testing.”

How is this relevant to building productive dialogue?

For those engaged in dialogue about the ethical and moral considerations related to the use of non-human animals in research, even this brief list makes clear that it is important to ask participants to begin by putting their basic starting assumption forward. Why? For one reason, because those assumptions are key to identifying whether there are potential areas of agreement or none at all.

For example, discussing refinement of laboratory animal care with an absolutist—someone fundamentally opposed to animals in laboratories—misses the point. No amount of refinement would make the work acceptable to them. In this case, the more critical questions for discussion would include consideration of the relative risks and potential benefits of failing to perform research for which there are currently no alternatives to animal-based studies. Consideration of species’ capacities and criteria for differential status– if any– would also be a useful starting point.

white-mouse-pair-in-cage-with-cardboard-tubeWhat about dialogue with those individuals and groups who do not provide a clear position? Does it matter?

Some would argue that it does not because the dialogue is only concerned with animal welfare and with reducing harm to nonhuman animals, or with pushing forward to develop non-animal alternatives for some types of research. In fact, framed in this way, most scientists are not only in the same camp, but are also the people who work actively to produce evidence-based improvements in welfare and development of successful alternatives.

The problem, however, is that real-time, critical decision-making about human use of other animals in research is not simple. It does require serious, fact-based consideration of the full range of risks and potential benefits, including consideration of the health and well-being of both human and nonhuman animals. It also requires clarity about alternatives, where they exist and where they do not. And it requires some understanding of the time-scales in which knowledge unfolds – often decades – and a basic appreciation for the scientific process.

It is easy to argue that developing non-animal alternatives for invasive research should be prioritized. But this argument does little to address the question of what to do now, what we do in absence of these alternatives, and what choices we should make as a society. Those questions are at the center of dialogue and the core issues with which the scientific community and others wrestle. To address them productively, and in a way that considers the public interest in both the harms and benefits of research, requires articulation of starting assumptions and foundational views.

Allyson J. Bennett

Excerpted from previous post “Fair partners in dialogue: Starting assumptions matter and they should be spelled out” 6/12/13


*For example, in the U.S., the laws and regulations that govern animal research mandate that proposals for use of vertebrate animals (including rats, mice, birds) provide, among other things: 1) a justification of the potential benefits of the work; 2) an identification of potential harms and means to reduce them; 3) evidence that alternatives to using animals are unavailable; 4) the use of the least “complex” species necessary to answer that question; and 5) much detail about the animals’ care and treatment, including the qualifications and training of the personnel involved. Consideration of these issues occurs not only at the stage of IACUC evaluation, but throughout the scientists’ selection of questions and studies to pursue, peer review and selection of projects for funding (more here). Furthermore, the entirety of the project must proceed in compliance with a thorough set of regulations designed on the basis of the 3Rs – reduce, replace, and refine (for more about regulation see here, more about 3Rs, here).

In other words, while there is always room for continued improvement, the structure is designed to require that the major ethical and moral considerations relevant to animal research be addressed by those involved in performing and overseeing the work. This structure also incorporates explicit consideration of changes that arise from new knowledge. That includes evolving knowledge about different species’ capacities and needs, as well as the development of alternatives to animal-based studies for particular uses. It also includes advances in our scientific understanding that demonstrate the greater need for basic research that requires use of animals to address key questions.

American Society of Primatologists’ statement of support for NIH primate research

The nation’s largest primatological scientific society, the American Society of Primalogists (ASP), has posted a strong statement sent January 21 in support for the scientist and research under attack by PETA.  The statement can be found on ASP’s website: https://www.asp.org/index.cfm

ASP home page Jan 2015

In its entirety, the letter reads:

“Members of the Board of Directors of the American Society of Primatologists would like to add our comments to the discussion of the validity and effectiveness of non-human primate research as it pertains to human behavior and medicine. Non-human primate research (on monkeys and apes) has had widespread effect on improving the diagnosis and treatment of many adult and childhood diseases. Studies that have employed the judicious use of non-human primates as models for human illness have improved our understanding of such disorders as autism, childhood leukemia, cerebral palsy, and mental health.1 The long-term research of one scientist, Dr. Stephen Suomi, has been called into question as a result of inaccurate, misguided and inflammatory media accounts. Our comments will address Dr. Suomi’s work and the value of non-human primates in understanding human biology, illness and behavior.

Dr. Suomi’s research has focused on the influence of variable environments and genetics on infant development, and by extension variation in adult behavior2. He and his colleagues found that early changes in the degree of attachment between mother and infant have real biological, not only behavioral influences on adult social behavior3. If this finding seems intuitive, it is evidence that the benefits of research have permeated not only the scientific, but also mainstream media4 and literature. Infant subjects are either mother-reared or reared in same-aged groups of monkeys. Infants may undergo temporary isolation during the study5 to facilitate comparison among groups that are reared differently. The goal of much of this research is to mimic separation that every social animal, including humans, undergo during their lifetimes and to understand why individuals respond differently to separation. One such research focus is the development of risk factors leading to mental illness in humans.

The American Society of Primatologists supports research on non-human primates that is carefully designed and employs rigorous research protocols. Dr. Suomi’s research and consistent funding by the NIH attests to his adherence to prescribed protocols and regulations.

Before research can begin, proposals are thoroughly vetted by both their institutional ethical oversight board (in the United States these are called Institutional Animal Care and Use Committees or IACUCs) and by the review boards of granting agencies (e.g., NIH, NIMH, NSF). This very extensive process requires prospective researchers to respond to questions such as those raised in your letter, e.g., your concern about redundant research. Per both the Animal Welfare Act and Regulations (AWARs) and the Public Health Service Policy on the Humane Care and Use of Laboratory Animals (PHS Policy), research funded by federal and state governments, as well as private foundations, must demonstrate that the project they propose will advance knowledge in the field, be relevant to human biology or behavior, and will not duplicate the efforts of previous research. The number of animals used in experiments must also be justified as well as the conditions in which the animals are housed, the duration of the project, and the protocols implemented during experiments. The scientists employed by the NIH have been leaders in the development of safe, effective, and reliable research protocols whether the research is done on mice or monkeys.

Because of the close genetic relationship between humans and non-human primates, monkeys are important models for studying particular biological phenomena, including the research conduct by Dr. Suomi. Nevertheless, non-human primates are rare in laboratory populations making up < 1% of the laboratory animals used in research (Government statistics from 2010, cited in Phillips et al., 20146). Furthermore, species are carefully matched to proposed studies.

We appreciate your attention to this matter, and ask that you please send us a response letting us know the charge to the NIH Bioethics Review Board.

Respectfully submitted,

The Voices of Reason Ring Through

In the days since the announcement that I had received a letter containing heinous death threats and razor blades from animal rights extremists opposed to my research, the voices of sanity and reason have started to be heard. From scientific and professional societies to non-scientists across the country, there is a strong support for the notion that biomedical research involving animals contributes irreplaceably to advancements in human and animal health and that because the use of animals in this research is responsible and humane, it is also justifiable and ethical. Many of these messages show particular support for our repudiation of these threats and our unwavering intention to continue the work that we feel morally obliged to conduct despite them.

In particular, scientific and professional societies have stepped up to voice their support for humane and responsible animal use in biomedical research and to condemn, in the clearest manner possible, the threats made by animal rights extremists against researchers.

The American Society of Primatologists, the nation’s leading scientific group dedicated to the study of “nonhuman primates, including their biology, care, and conservation” took the lead in a resolution posted to their website.

The American Society of Primatologists condemns these terrorist actions. Terrorism does not, and will not, contribute to the betterment of animal welfare. Nor does it contribute to civil dialogue and thoughtful consideration of the role of responsible, humanely-conducted and ethical animal-based research in contributing to scientific and medical advances.

The American Society of Primatologists calls upon groups and individuals concerned with animal welfare to join in universal and public condemnation of all terrorist activities directed at members of the scientific community.

The American Medical Veterinary Association is comprised of more than 80,000 member veterinarians who are dedicated to advancing the science and art of animal, human and public health. They reasserted their position in a recent press release, also posted on their website.

Animals play a central and essential role in research, testing and education for continued improvement in the health and welfare of human beings and other animals. … The use of animals used in research, testing and education is a privilege carrying with it unique professional, scientific and moral obligations.

…  America has no room for terrorist activities that threaten not only that discourse but the lives of our scientists and their families. We condemn all acts of violence, vandalism and intimidation directed toward individuals and facilities engaged in the ethical use of animals for research.

This position is paralleled by the American Association for Laboratory Animal Science (AALAS) who, in a statement on their website, affirms their commitment to preserving laboratory animal welfare in the context of humane research aimed at conquering human disease.

“Acts of terrorism do not result in improvements in animal welfare. Progress comes only from thoughtful discussion and scientific assessment of alternative methods that refine the animal research process–efforts that AALAS itself fosters through educational and scientific programs. Terrorism in the name of “animal rights” jeopardizes the lives of people and animals–in the present by the violence itself, and in the future by hindering the progress of ethical animal-based research designed to find cures and treatments for diseases that affect humans and animals. The AALAS membership extends heartfelt support to our scientific colleagues and their families who have been affected by threats and acts of violence.”

Finally, leading scientific societies have spoken up as well. The Society for Neuroscience, , the world’s leading organization of scientists dedicated to exploration of the brain and its diseases,  released a statement on this matter.

The Society stands united with Dr. Jentsch, the members of his team, and all researchers who use animal models to advance scientific discovery, and SfN is committed to promoting public awareness of the vital role of animals in research and supporting all scientists that come under attack.


The American Physiological Society, which represents more than 10,000 members devoted to fostering education, scientific research, and dissemination of information in the physiological sciences, posted a policy statement to their website supporting, in the broadest manner, researchers under attack and the value of the work that they do.

…[M]any scientists … have been harassed or threatened because they work with animals. Research involving animals plays an essential role in efforts to discover causes, preventions, treatments, and cures for disease. Knowledge obtained through research with animals has saved many lives and improved the quality of life for millions of people and animals. Scientists recognize that they have ethical duties both to relieve suffering through research as well as to provide humane care for research animals. Moreover, the use of animals in research is subject to strict regulatory oversight.

The American Physiological Society condemns extremist actions against researchers in the strongest possible terms: It is thuggery, pure and simple. Harassment, threats, and violence contribute nothing to the betterment of animal welfare, nor do they promote dialogue or thoughtful consideration of serious issues.

Additionally, I have received countless emails and phone calls from individuals around the country who have felt the sting of mental illness in their own lives, or in the lives of those they love. Not surprisingly, I have also been the recipient of emails encouraging me to stop conducting animal research, but those missives are outnumbered more than 10-to-1 by expressions of appreciation and gratitude for biomedical researchers. People from all walks of life have chimed in, expressing their personal and unwavering belief that animal use in medical research is justifiable and ethical.

A science educator from the upper mid-west:

Thank you for sticking up for all those hard working folks who do science each and every day… not to get rich… but because they love people, they love animals, and they are deeply  committed to their mission to make this world a better place.

A university undergraduate student from the Pacific northwest:

I write to express my support for your research and to note that I greatly respect your decision not to be dissuaded by terrorist tactics.  The benefits of your research into chemical dependence and schizophrenia are and will continue to be considerable, and the use of animal subjects in this case is, in my  opinion, amply justified.  You have my continuing support and the support of many other informed individuals.

A Los Angeles local:

Thank you for your research into addiction and cognitive changes in schizophrenia.  And a special thanks for not being bowed by extremist Animal Rights people.  It’s the people like you who are working so hard to help us.

Years ago, I read an article in the LA Times about a lab … that was burned to the ground by these dangerous individuals.  That lab lost over 10 years of research into Osteoarthritis…

Flash forward a decade and I was diagnosed with a chronic illness, rheumatoid arthritis.  Nothing like getting a chronic illness of your own to realize how important research is to the patient.

A bio-technology researcher from the mid-Atlantic:

All of us in science are working to improve the lives of all, and to relieve suffering wherever we can.  The fact that our work is now used as an indictment against us by vigilante thugs is inexcusable.  Thanks for your courage in standing up to their threats, always shrouded in the cowardice of anonymity, while you try to lead your life in public without compromising your ideals and scientific goals.  Good luck to you and to your collaborators.

Many of these sentiments were summarized in a recent editorial written by the incredible undergraduate students who manage UCLA’s campus newspaper, the Daily Bruin:

The idea of such misguided activists destroying the lives of world-class researchers through their tasteless, violent tactics is atrocious.

These attacks should create concern for the community at large, because the implications are far-reaching. Medical breakthroughs occur in large part as a result of the valuable research that scientists perform.

Mailing blades to a researcher and continuing threats on his life endangers future progress and is a threat to every UCLA student, faculty member and researcher.

Intimidation and death threats should never be the solution, no matter how bad an action may seem to somebody. What ever happened to dialogue?

These statements indicate that scientists and non-scientists alike often stand strong in support of biomedical research and understand that there are circumstances where the use of animal models is justifiable. These messages further expose just how much damage to their own credibility animal rights extremists cause when they continue to use fists, razors and hate speech to push their agenda.

My colleagues, trainees and I extend our most heart-felt thanks to all that have reached out to offer support, as well as to those who quietly support research and researchers around the world. The attacks by animal rights activists are insidious and discouraging, but the voices of encouragement, coupled to our knowledge that the work is ethical and responsible, ensure that we will continue pursuing solutions for the problems of human and animal health that biomedical investigation can address. Our experience underscores the notion that vocal support for research and researchers ensures overwhelming support and appreciation, and we call on others to join us in our effort.
