From Boingboing.net Foundations of Research The “Common Rule” criteria for Human Subjects Protection The Common Rule Research institutions are mandated to have boards – Called Institutional Review Boards – that provide ethical review of all Federally funded research. That review follows seven elements, called the Common Rule. Most Universities apply the same standard to all research, whether federally funded or not. 2 Foundations of Research The Common Rule The Common Rule Minimize risks Risks must be reasonable Recruit participants equitably Informed consent Document consent Monitor for safety Protect vulnerable participants & maintain confidentiality 3 Foundations of Research Minimization of risks 4 Core issue: Risks should not exceed those of everyday behavior.

In the 1960s through the 70s service members and, in some cases, prisoners were given varying doses of LSD and other psychotropic drugs to test their possible use as psychoactive chemical weapons. Some these exposures were with fore-knowledge and consent, at other times drugs were slipped into food to test their effects when unanticipated. Click below for an excellent piece in The New Yorker.

Other testing administered known or potential toxins to gauge their effects. Typically, pharmaceutical companies would work with State officials to gain access to prisoners. Prisoners “volunteered” for the studies, although were rarely fully informed about the agents they were taking. The shameful history of this testing led to very strict regulations being imposed in the 1990s. Today there is renewed debate about the prospect if prisoner testing were placed on prison testing.

As with prisoner research, animal testing has an ugly history, but has made invaluable contributions to human health. PETA, of course, opposes any animal testing (click image). NIH and organizations such as Foundation for Biomedical Research argue in Defense of responsible animal testing. Scientific American calls for ban on animal testing for Cosmetics. Many companies advertise their products as animal-testing free, although many use ingredients shown to be safe through prior animal work. The Scientist has an excellent series on animal testing, including the increasing number of alternatives to animals. Foundations of Research 9 Risk of harm to Participants, cont.

These studies can be ethical if participants are carefully screened (e.g., for no evidence of alcohol abuse…) and monitored during the experiment. Ethical constraints must be very strict in this area, particularly if deception is involved. Foundations of Research 10 Risk of harm to Participants, cont.

Research harms; changes in self perception. • In 1962, in the wake of the Nuremberg Trials of Nazi war crimes, Stanley Milgram wanted to discover how common citizens could be led to commit clearly evil acts. • He recruited participants for a “Memory study”, where they would serve as instructors. • Milgram hired actors to portray the ostensible “Learners”. • Milgram thus used deception in his recruitment materials and study instructions. • Any deception study is ethically problematic because participants are not providing accurate informed consent. • Studies that use deception to hide hypotheses from participants typically have no other potential study harms. • Milgrams’ use of deception was unethical; Participants consented not knowing they would be subjected to substantial stress. 12 Foundations of Research Risk of harm to Participants, cont.

E.g., leading participants to believe they were Click for the study web capable of harming others site. In 1971 the U.S. had been subject to several tragic prison riots. Political debate focused on whether criminals – the great majority Black and poor – were cognitively or psychologically “impaired” to the extent that they could not function in society. Sociological research at the time described the effects of “total institutions” such as prisons or psychiatric hospitals, that actually created deviant behavior. Phillip Zimbardo set out to test this experimentally, by constructing a realistic prison in the Stanford Psychology Dept. basement, and randomly assigning male undergraduates to the roles of prisoners or guards. Consistent with the hypothesis, the students – all affluent, white, well educated and screened for psychological health – acted little different than those at Attica State Prison, where riots had taken place. As with the Milgram experiment, participants were left with the knowledge that, whether prisoner or guard, they were capable arbitrary brutality.

Changed self-perception E.g., leading participants to believe they were capable of harming others Embarrassment Loss of confidentiality or privacy Many studies address coping or risk behavior in populations that may be stigmatized. For example, the author conducted AIDS research among gay and bisexual men from the 1980’s forward. During much of that time being “outed” as gay/bisexual could lead to job loss to actual violence. As more men (and women) became infected with HIV, that status became a second important source of stigma. Loss of confidentiality through sloppy record keeping, or even recognizing a research participant on the street, could have real adverse consequences. Research with potentially stigmatized people – whether due to poverty, criminal background, abuse history, or otherwise – requires very careful protections to ensure that vulnerable participants are not socially harmed just by being a research participant. Foundations of Research 17 Risk of harm to Participants, cont. Physical harm Psychological harm Social or political harm Portraying social groups in a negative light, e.g.: The Common Rule Minimize risks Reasonable risks Equitable recruitment Informed consent Document consent Data monitoring for safety Protect vulnerable participants & maintain confidentiality • Interpretations of research results that suggest lower intelligence among lower socio-economic status or minority participants; • “Pathologizing” minority groups by problem – focused research and reporting: Research funding addressing poor, GLBTQ, minority and other populations typically focuses on problems: drug abuse, domestic problems, criminality…; Although these are important topics, the consistent portrayal of a community in ‘problem’ terms can enhance negative stereotypes. Ignoring or relying too strongly on some groups: e.g., women or minorities in clinical research. Foundations of Research Risk of harm to Participants, cont. 18 What makes research vulnerable to research harm? Strong financial pressure for study results: Publication & grant pressure: Advancement in the research industry- promotions, recognition, getting grants or contracts – requires that investigators consistently publish positive results. Simple bias or prejudice: The ability to market clinical interventions – new drugs, medical devices, behavioral programs – depends upon positive results of efficacy trials. Most researchers are Caucasian, with middle or upper-middle class backgrounds; The “Ivory Tower” syndrome; it is common for researchers have little direct experience with the populations they are studying. Lack of institutional controls Active Institutional Review Board Study monitors Up-front ethical reviews & ongoing monitoring for ethical compliance can prevent potential harms.

The Common Rule Minimize risks Reasonable risks Equitable recruitment Informed consent Document consent Data monitoring for safety Protect vulnerable participants & maintain confidentiality • How much greater, for how long? Are the potential harms – ‘costs’ – justified by the likely knowledge to be gained, i.e., potential benefits? Potentially harmful research may be justified if it provides invaluable data, e.g.: Milgram obedience studies; Zimbardo prison experiment; Intrusive animal studies; Studies that pay people to take medical or behavioral risks. Foundations of Research 21 Reasonableness of risks Research with little harm may still be unjustified if it will not provide useful data: Research always requires time, effort, potential embarrassment…; Research that is trivial or incompetent may be inherently unethical for those reasons. Weighing risks against potential benefits is difficult and complex… We lack a scientific metric for evaluating degrees of potential harm. The benefits of research are rarely guaranteed. Even research with scientific or applied benefit often has no direct benefit for the study participants themselves. The Zimbardo Prison Study subjected college students to real stress… …but provided valuable data about how social roles and the physical setting affect behavior.

How do we ensure that all social groups are represented? Some groups are less likely to enlist than are others; How much should Investigators try to overcome peoples’ reluctance to join a study? At what point does that become coercive? Some groups – drug abusers, those in poverty – will respond to even a small monetary incentive to join even high risk studies. Is offering a monetary incentive to those individuals coercive? Are they treated inequitably by not being offered money?

In 2014 the Senate released a report describing CIA “enhanced interrogations” during the Iraq war. They concluded that the CIA engaged in torture, and that the program was unsuccessful. It had been widely known that APA-sanctioned Psychologists had helped design and administer the interrogation program. In 2015 an ethics panel of Psychologists and human rights activists issued a report on the show deep involvement of the APA in the Bush era torture program. Click for NYTimes.com overview.

Foundations of Research 39 Case study of unethical use of scientifically validated techniques. Beginning in 2003, the APA worked closely with CIA Psychologists James Mitchell and Bruce Jessen to develop “enhanced interrogation” (I.e. physical and psychological torture) used at Guantanamo Bay and other “Black sites” around the world. APA worked with the Bush White House, State Department and CIA to tailor it’s ethical standards to allow Mitchell and other Psychologists to develop and conduct the CIA interrogation program. Mark Wilson/Getty Images More than a decade after George J. Tenet, then From the New Yorks Times article. the C.I.A. director, signed a secret order suspending the agency’s use of enhanced interrogation techniques, the American Psychological Association’s actions are coming under scrutiny. The White House actually help write a 2005 APA policy statement allowing Psychologists’ assistance in “enhanced interrogation”. The secretive committee that prepared the document was comprised primarily of Military Psychologists. Dr. Martin Seligman, past president of APA, contributed to the CIA effort by presenting his theory of Learned Helplessness as a method of extracting information. From a 2004 CIA memo : "The goal of [harsh] interrogation is to create a state of learned helplessness and dependence conducive to the collection of intelligence.” Foundations of Research Case study of unethical use of scientifically validated techniques. 40 The American Psychiatric Association & American Medical Associations refused to endorse their members’ involvement in interrogations: The CIA were linked to torture & theory unlawful interrogations The misuse of scientific detention; and data can have very serious As helping professions, the Psychiatric and Medical consequences. communities refused to sanction or participate in torture. From the New Yorks Times article. In it’s 2005 report, the APA ethics committee declared that, as a research organization, it was exempt from the ethical standards of “helpers”. (This resembles the Bush Administration's declaration that those held at Guantanamo, Abu Graib and elsewhere were “detainees” in a battle zone, rather than “prisoners of war”, so the Geneva Convention guidelines for the ethical treatment of prisoners did not apply.) After years of boycotts and protests, in 2008 APA finally altered its stance and accepted the “do no harm” ethical stance of helping professions. See a chilling documentary of the APA’s adoption of torture policy here.

A false positive is a positive result due to to error, biases, or subtle (…not so subtle…) fraud. It appears that science generally, and the behavioral sciences in particular, are rife with false positives 45 Foundations of Research 46 False Positives Inaccurate or non-reproducible (false positive) results often stem from confirmatory bias among investigators, sloppy work, or inappropriate statistics. Replication is a process where a study is repeated exactly, to ensure the results were not due to a fluke or the specific conditions in one lab (i.e., an artifact). Converging studies address a topic using different methods or measures, to ensure the results are not simply due to the general method used. Research journals (and grant awards) strongly favor new, exciting or innovative results. So, few replicating or converging studies are performed; it can be difficult to get them published. A lot of work then goes ‘unchecked’ – and replicating studies that are conducted often fail to reproduce the original result. The Reproducibility Project attempted to rigorously replicate 100 Ψ studies from 2008. Over 60% showed far weaker (or no) results when reexamined.

Dr Head said the study found a high number of p-values that were only just over the traditional threshold that most scientists call statistically significant. “This suggests that some scientists adjust their experimental design, datasets or statistical methods until they get a result that crosses the significance threshold,” she said. “They might look at their results before an experiment is finished, or explore their data with lots of different statistical methods, without realising that this can lead to bias.” many publications we have and the quality of the scientific journals they go in. “Journals, especially the top journals, are more likely to publish experiments with new, interesting results, creating incentive to produce results on demand.” Works against longer research time frames, and almost rules out studies that attempt to replicate previous studies to test whether their results are actually robust. Foundations of Research Misleading, biased or fraudulent results. 49 There is substantial pressure – and temptation – to cut corners, introduce subtle biases, or engage in simple fraud to produce positive results. “Tweaking” study designs to ensure positive results; Ideally, a study is designed to test the hypothesis: The null hypothesis and the alternate hypothesis (négative & positive results) each have a fair chance of emerging. Unfortunately, many studies are conceived less to test a hypotheses than to prove or confirm one. A strong confirmatory bias can induce both intentional and unintentional biases in favor of positive results. Researchers may repeat experiments, tweaking one element or another – the setting, the measurements, statistical analyses, participants – until they get the expected result. This powerful confirmatory bias is often not seen as a problem.

Unfortunately, many studies are conceived less to test a hypotheses than to prove or confirm one. A strong confirmatory bias can induce both intentional and unintentional biases in favor of positive results. This can be a consequence of a strong theory: The researcher is convinced (based on previous studies, with or without clear evidence) that the theory is correct. The point of the study is then not to test whether the theory is correct – we already “know” it is (or want it to be) – but to find procedures that will empirically confirm it. Foundations of Research Misleading, biased or fraudulent results. 2. Behavioral researchers typically stage manage the experimental setting, instructions, available information and the like. • • This is a virtue if the stage management simply enhances external validity, by making the setting more “real world” –like. • This is a serious problem if it pushes the participant toward confirming the hypothesis. “Stage managing” …limiting participants’ behavioral choices Making the stimulus all s/he can respond to; Implicit Attitude Test, stereotype research, very minimal stimuli and moral judgments 52 Foundations of Research Misleading, biased or fraudulent results. 53 “Tweaking” study designs to ensure positive results, Stage managing 3. “Cherry Picking” results; publishing only those that “work”. Multiple statistical tests at p<.05. (1 / 20 by chance…) Multiple variables /selective choice of variable(s) and post-writing the hypothesis. (not necessarily consious fraud; making sense of the findings, but inadvertantly making them sound like they had been predicted. Multiple complete studies File drawer phenomenon Foundations of Research Selective choice of variables (A variation on Cherry picking): Large data sets contain multiple variables. Investigators can cheat by re-writing their hypothesis to address the variables that they already know to “work” in the study. o For example, Bohannon’s fake chocolate study assessed multiple possible outcomes of a diet program. o His showed results only for the one variable that happened to change. o Given how many variables he tested, there was over 90% chance that at least one of them would look a little different at the end of the study. This form of fraud is not always intentional or malicious; with complex data our bias toward positive results will draw attention to only some outcomes. As we saw in the Fen Phen scandal, however, company-sponsored researchers occasionally simply ignore negative outcome variables. 54 Foundations of Research Multiple studies Pharmaceutical companies have been particularly implicated in this: o Companies would run multiple trials of a new drug, and submit only the successful outcomes to the FDA for approval. o The FDA now requires submission and access to all drug trials. This has been called “the file drawer problem”; journals have little interest in negative results, so only positive outcomes get submitted for publication. Researchers rarely attempt to publish negative results Although this is changing as researchers become aware of the positive results bias, and journals become more accepting of negative results. 55 56 Foundations of Research 4 P-hacking Dr Megan Head of Australian National University recently published a study of 100,000 research papers published around the world, spanning medicine, biology and psychology. (Click for an overview). Her data suggest “p-hacking” as an important source of false positive research results: Dr Head said the study found a high number of p-values that were only just over the traditional threshold that most scientists call statistically significant. “This suggests that some scientists adjust their experimental design, datasets or statistical methods until they get a result that crosses the significance threshold,” she said. “They might look at their results before an experiment is finished, or explore their data with lots of different statistical methods, without realizing that this can lead to bias.” From: PHYS.org, Social Sciences, March 18, 2015; http://phys.org/news/2015-03-scientists-unknowingly-tweak.html.

There is substantial pressure – and temptation – for actual fraud. Career advancement – and funding – requires finding positive results; Diederik Stapel, a Dutch social psychologist, perpetrated an audacious academic fraud by making up studies that told the world what it wanted to hear about human nature. Click for New York Times overview. Koos Breukel for The New York Times Experiments must “work” to be published, to get drugs licensed, to apply for further funding… As a consequence, U.S. Behavioral research shows a strong bias toward positive results. The varieties of research fraud Simple faking; Deitrik Stapel successfully faked 20 years of data (click image). Stapel perpetrated the largest fraud in modern behavioral science. He made up results that were plausible and interesting (“sexy”, in his word), but close enough to real results to not be questioned He was aided by trust and lack of strong oversight in the research industry. Over a 20-year fake research program he published 55 research papers, 11+ Doctoral dissertations, and secured substantial research funding. Foundations of Research The consequences of biased research studies What are the consequences of subtle (or not so subtle) cheating in research? Compromised or poorly conducted research… “Tweaking” study designs to ensure positive results, Cherry picking only positive results, Statistical “errors” favoring the hypothesis, Simple faking, Lax standards for evaluating results, … can lead to the appearance (or gross overstatement) of positive results in data that actually do not support the hypothesis. Evidence from journal publications shows Psychiatry / Psychology to have a very strong “positive results bias”: 59 Foundations of Research Behavioral scientists are responding to the replication crisis by being more transparent about all their data; NYT paper here. 60 Foundations of Research Quiz; Think about each possible answer, then choose the one you would have clicked in class. How do we determine whether a research risk is “reasonable”? A = A cost – benefit analysis B = No risk is acceptable C = The Research Investigator decides if the study is too risky D = Risk cannot exceed what riskier people in society face anyway 61 Foundations of Research Quiz Which of these is most important as a cause of research harms, or data that are inaccurate or actually fraudulent? A = Science attracts ethically questionable people B = Financial and professional pressure for positive research results C = A lack of clear methods for many research areas D = It is not possible to monitor a study once it is underway 62 Foundations of Research Click I want to recruit poor people for a study of an experimental vaccine. To ensure I get enough people to take the vaccine I offer $200 dollars for each of five study visits. Is this ethical? A = Yes, taking an experimental drug is risky and people should be paid well. B = No, the researchers do not know if the vaccine works yet. C = Yes, as long as they are told whether they are getting the real drug or the placebo. D = No, that rate of compensation for poor people is coercive. 63 Foundations of Research Click Are experiments that use deception ethical? A = Yes, as long as the investigator thinks the results may be important. B = No, participants cannot give informed consent if they do not know what the experiment is about. C = Yes, as long as there is IRB review and systematic debriefing after the study. D = No, IRBs will not sanction deception in research. 64 Foundations of Research SUMMARY Overview The “Common Rule”: core guidelines Minimize risks Risks must be reasonable Recruit participants equitably Informed / Document consent Monitor for safety Protect vulnerable participants & maintain confidentiality Larger institutions have key roles in maintaining ethical behavior Institutional Review Boards (IRBs) Organizations such as the APA can behave in clearly unethical fashion The “research industry” directly presses for questionable, mediocre or fraudulent research. 65 66 Foundations of Research The Common Rule: Core criteria for ethical research The Belmont Report and the Informed Consent document Respect for persons Beneficence Justice Foundations of Research Belmont Report 67 (CITI training) 1.
