    Send me email at: Internet-based mailing lists and newsgoups frequently receive requests for participation in on-line surveys. (A discussion about such requests, circulated to members of the Breast-Cancer mailing list in July, 1997, had as the subject line: "Researchers - A Plague of Angels?"!). The purpose of this article is to provide three examples ('case studies') of requests of this kind, and to comment on some ethical implications of such requests. From an ethical perspective, Internet-based mailing lists and newsgroups might regarded as having some of the characteristics of 'virtual collectivities'. The Council for International Organizations of Medical Sciences (CIOMS) defines 'collectivities' as "population groups with social structures, common customs, and an acknowledged leadership".[1] Collectivities include nations, cultural groups, small indigenous communities and some neighbourhood groups. The CIOMS definition is also explicitly intended to include families. In contrast, 'groups' are defined solely in "demographic or statistical terms, with neither leaders nor representatives".[1] It could be argued that Internet-based mailing lists or newsgroups should *not* be regarded as 'collectivities' in the sense of the CIOMS definition, because the extent to which they exhibit either formal governance structures, or acknowledged leadership, may be open to question. For the purpose of this article, it will be assumed that current views about the ethics of research involving 'collectivities' may provide a useful context within which to consider the ethics of research involving Internet-based mailing lists or newsgroups. The three major federal agencies which support research in Canada have prepared a draft 'Tri-Council's Code of Conduct' for research.[2] One section (Section 13) of the Tri-Council's Code of Conduct that addresses research with 'collectivities'.[3] Two aspects of the guidelines contained in Section 13 will be highlighted here: "Article 13.2: Except where it is self-evidently not the case, the researcher, regardless of the nature of the research to be undertaken, must consider the group to be researched a 'collectivity' as defined above. Therefore, if such a researcher does not wish to follow the Code of Conduct respecting 'collectivities', it is incumbent upon her or him to explain how the group to be researched is not a collectivity as it has been defined above".[3] And, "Article 13.6: When undertaking research with a family, community or other collectivity, the researcher may not begin until permission has been obtained from the appropriate authorities for that collectivity. Furthermore, obtaining group and individual consent before beginning any research involving a collectivity, or its members, must be regarded as a minimum requirement".[3] A key refinement of the definition of a 'collectivity' is included in a revised version of the Tri-Council's Code: "They [collectivities] are ordinarily groups in which there is mutual recognition of membership both by those in the group and those outside of it".[3] This revised definition does not include a requirement for formal governance structures, nor for acknowledged leadership. Below, I outline three (real, not hypothetical) 'case studies' that I think are relevant to Internet-based research, and offer some preliminary comments and questions about them. These comments and questions will be based on current widely-accepted guidelines about research ethics, as described by CIOMS,[1] and by the Tri-Council's draft report.[2] The first three 'case studies in this series are: 1. Surveys - Case #1: A survey questionnaire, with a subject heading 'Query', was posted to the Breast-Cancer mailing list (at on March 17, 1997.[4] The author of the message began by identifying himself as a student, at a School for Math and Science, who is required to do a senior thesis. He then outlined his plans for the thesis: "My thesis this year consists of a comparison of radiation chemotherapy versus combination chemotherapy using other chemicals. An appendices of alternative medicine and sources to get more information will be included, but what follows is the part that I need your help on. Although I am seeking to become a doctor, I want to add a more "human" aspect to my thesis, so I am asking you to submit your answers to the following questions, but please be advised that some of the questions are quite personal". This introduction was followed by a questionnaire. The first question was: "1) Can you describe how you felt when you or someone close to you was diagnosed?" This question was followed by more questions, asking about "philosophies of living life", about plans "to cope with the aspect of death and hope for a cure", about (if a caregiver) how to "cope with the feeling of hope and despair", about what advice to give to "someone who has just been diagnosed", and about sources of "your best support". The last question (of a total of 7) was: "7) What is an impression that you wish to leave on the world?" The message concluded with a paragraph that included an apology for writing "such a depressing e-mail", and the comment: "there is no way that a person can be empathic to the plight of someone who has had a problem in their life, unless you have experienced it, and even then the experience is different. I have never experienced this pain, hope, or tragedy, but I want to , and to make those that read my thesis feel it all through their body and to the depths of what we call a soul". Comments about Case #1: Subsequent information sought by mailing list members, or supplied by the original author of this questionnaire, revealed that the author was not an impostor, that he was a student at a secondary (high) school, and that he was considered to be one of the top students at his school. This student stated plans to study medicine, as a result of direct experience with cancer (deaths of a grandmother, grandfather, and close personal female friend). Although it appeared that the proposed research project had been approved by the student's faculty advisor, it apparently had not been subjected to reviews of scientific merit and ethical acceptability of a kind that normally would be expected of 'real' research projects (such as research projects involving human subjects, designed and carried out by faculty members at major universities). Subsequent comments sent by other subscribers revealed a range of opinions about this survey, from ones that were supportive of the student's plans, to ones that criticized such use of the Breast-Cancer mailing list. (This list has, as major purposes, the provision of information, support and advocacy about breast cancer). Should one conclude that it is inappropriate for the standards of research ethics to be less rigorous at the secondary school level (if the intent of the research is considered to be benevolent) than the standards for research ethics at the university level? In other words, is it inappropriate for the standards of research ethics to be dependent on the particular context within which the research is to be done? 2. Surveys - Case #2: A survey questionnaire, with a subject heading 'Survey: Circumcision and the Waterworks' was posted to the newsgroup on April 11, 1997.[5] The purpose of this survey was (at least in part) to explore possible relationships between circumcision and prostate-related problems. The 2nd and 3rd paragraphs of the message read as follows: "This questionnaire is journalistic in intent, is not sponsored by any academic or other body and is not a part of any scientific research programme. However the results will be analyzed according to strict scientific standards, and anonymous data can be provided to reputable medical research institutions". "All forms will be stored and entered anonymously. Email headers, names or addresses will not be preserved with the saved forms". The survey begins with a question that asks whether or not the respondent has been circumcised, and, if so, at what age. It includes several questions about urinary characteristics or problems. The final (12th) question is: "12. Do you feel that being circumcised/uncircumcised has affected your waterworks in any way? If so please give details .... ..........................................................." Comments about Case #2: Note that it is stated very clearly that the questionnaire is journalistic in intent, that it is not sponsored by any academic or other body, and is not part of any scientific research program (however, it is also stated that "anonymous data can be provided to reputable medical research institutions"). If this survey happened, in fact, to be part of a scientific research program supported by a reputable medical research program, the research protocol of which it formed a part would normally be expected to have been reviewed, in advance, by an appropriately-constituted Research Ethics Board (usually called an IRB in the U.S.A.). The membership of such a Board would normally include non-researchers (such as ethicists or lawyers) as well as researchers. Ideally, such a research protocol should also have been peer-reviewed in advance in relation to its scientific merit. At the very least, a research questionnaire should have been pretested, in a preliminary attempt to evaluate its clarity and feasibility, reliability, and validity. Does the inclusion of the 2nd paragraph (see above) in the 'Waterworks' questionnaire imply that this questionnaire does not need to meet the same ethical standards that are usually applied to questionnaires designed for use in a scientific research program? Should one conclude that it is inappropriate for the standards of journalistic ethics to be less rigorous than the standards for research ethics? What if it turns out that the responses to the survey are, in fact, subsequently used as part of a research study (e.g. as preliminary data to help guide the development of a 'final version' of the questionnaire, designed for use in a scientific research program)? Should such use of the results be avoided, because, if such results are used in research, then the original 'journalistic survey' becomes, in effect, research disguised as 'journalism'? If research is disguised as 'journalism', then might it be claimed that some deception was involved in the process used in the development of the 'final version' of the questionnaire? 3. Surveys - Case #3: A short message was posted by a college student (email address provided, but no author's name) on April 11, 1997.[6] The message was cross-posted to several "alt-support" newsgroups, including those for cancer, grief, single-parents, arthritis, multiple-sclerosis, anxiety-panic disorder, and depression. The purpose of the short message was to ask people to complete an on-line questionnaire about on-line support groups. The questionnaire itself was not included in the message. Instead, the location of a web page containing the on-line questionnaire was provided, and people were asked to: "Please complete my on-line questionnaire if you have a moment". This short message elicited quite a few responses sent to the newsgroups, most of which ranged from tolerant to very negative. There was concern about cross-posting to newsgroups involving people who feel particularly sensitive, fragile or vulnerable. Some people felt that their privacy had been invaded, and that they were being "used as human guineapigs". The alternative (minority) view was that such newsgroups are public, that the main problem is people with commercial interests who approach such groups. It was suggested that a researcher who posts a short message, which simply provides the location of a web page containing an on-line questionnaire, should be regarded with tolerance. Comments about Case #3: In circumstances where concern is expressed about a particular survey research project, it seems likely that responses to an on-line questionnaire may be quite biased, and thus be of questionable scientific validity. For example, selection bias is always a problem in survey research, in that the people who choose to respond to a survey may not be at all representative of the larger group from whom they have been self-selected. Appropriate scientific sampling of the membership of an Internet newsgroup or mailing list poses very difficult methodological (and ethical) problems. For example, are there some newsgroups or mailing lists that should be regarded a 'semi-private' zones in cyberspace, ones that should not be intruded upon by researchers whose only goal is to do survey research? Indeed, should on-line research only be done within the context of "participant-observer" research, where the researchers are known (and trusted) members of the newsgroup or mailing list, and are regular participants in a variety of discussions? If one of the goals of the "participant-observers" is to undertake on-line survey research, should they then be expected to prepare formal research protocols which should be shared with (and developed with the help of) the members of the newsgroup or mailing list? Should such protocols, when in final form, always also be evaluated in relation to their scientific and ethical acceptability, as would normally be expected for all (university level) research protocols? Discussion: Case #1 raises the question: Is it inappropriate for the standards of research ethics to be influenced by the particular context within which the research is to be done? My own opinion is that there are both empirical and conceptual justifications for such an influence. Empirically, all surveys (or polls) are not the same (consider the examples of scientific surveys, political surveys, and marketing surveys). Conceptually, if standards of research ethics ignore the particular context within which the research is to be done, then they may sacrifice pragmatic flexibility in an (in my opinion, vain) effort to achieve theoretical ethical neatness. Case # 2 raises the question: If research is disguised as 'journalism', then might it be claimed that some deception was involved? In my opinion, an answer is "probably yes". However, if the original purpose of the survey was indeed 'journalistic', not 'scientific', but very interesting results emerged, would it be ethically-unacceptable for these results to then be used as a basis for 'real' scientific research? I think not - but the contextual details would matter (see Case #1). Case #3 raises the question: Should on-line research only be done within the context of "participant-observer" research, where the researchers are known (and trusted) members of the newsgroup or mailing list, and are regular participants in a variety of discussions? My own answer would be: "probably yes, but the context matters" (see above). For example, within the context of mailing lists involving vulnerable groups, some participants may regard the mailing list as a kind of sanctuary, and thus may regard an intrusion by a researcher into this sanctuary as a violation of the participant's right to privacy. Some Concluding Opinions and Suggestions: I think that on-line survey research poses some significant ethical and methodological problems. For example, its scientific validity is likely to be questionable, at best. If such research is undertaken at all, perhaps it should only be regarded as a form of 'pilot study', useful in the initial design and pre-testing of a survey questionnaire? For example, in private correspondence, a colleague (Barry, see Acknowledgment) suggested that it would be quite feasible for someone to establish a number of fake email addresses, and then to fill out a number of on-line questionnaires with fake data. How would a researcher know which email adresses were fake and which were not, and which responses were valid and which were not? From the perspective of potential participants in the research, there should be awareness that the 'investigator' may be an impostor, or may have ulterior motives, or may be poorly-qualified to undertake the research, for either scientific or ethical reasons. From the perspective of researchers and ethicists, there should be awareness that some newgroups or mailing lists may fit the definition of a 'collectivity' better than that of a 'group'. Investigators (and IRBs) should be aware of the ethical issues raised by research with 'collectivities'. Mailing lists or newsgroups should be selected with care, approached with sensitivity, and treated with respect, with careful attention to the purposes and the 'culture' of that particular newsgroup or mailing list. The members of mailing lists or newsgroups, if treated with inappropriate insensitivity, are not helpless. For example, they could take steps designed to invalidate a survey (see Barry's proposed means of doing so, outlined above). An attached Appendix includes some questions that might be answered, in advance, by researchers who propose to carry out an on-line survey (and which, if not answered in advance, might be asked by potential participants in the research, before they decide whether or not to participate). The ethics of on-line survey research obviously involves balancing a number of sometimes conflicting rights and duties, including those related to privacy, freedom of inquiry, and participation in a 'collectivity'. Of these, the question that most needs further attention from research ethicists may be the CIOMS definition of a 'collectivity', as "population groups with social structures, common customs, and an acknowledged leadership".[1] If the concept of a 'collectivity' is to be flexible enough to be applicable to a wide range of contexts, including populations groups of the kind brought together by Internet-based mailing lists or newsgroups, then perhaps this definition needs to be modified, and/or more attention needs to be paid to the different ways in which 'social structures', 'common customs' and 'acknowledged leadership' may themselves be defined. Perhaps a better definition is: "They [collectivities] are ordinarily groups in which there is mutual recognition of membership both by those in the group and those outside of it".[3] Internet-based mailing lists do, of course, have 'acknowledged leadership' in the person of the 'list-owner(s)'. Permission probably always should be sought from the principal list-owner about contacting members of that mailing list in relation to a proposed survey research project. However, my own opinion is that list-owners should not be expected to speak for the mailing list membership as a whole. Instead, I suggest that survey researchers should be asked to consider the questions posed in the attached Appendix, and to provide answers to these questions. Individual list members can then make their own informed decisions about whether or not they wish to participate in the research.

If it is accepted that a subscription to a mailing list like the Breast-Cancer Discussion Group involves "mutual recognition of membership", then such a mailing list does fit this definition of a 'collectivity'. If it is accepted that such a mailing list fits this definition of a 'collectivity', then the main issue, from a research ethics perspective, is whether or not messages posted to the mailing lists may be regarded as information that is in the public domain. I'll argue (click here) that messages sent to mailing lists are the intellectual property of their authors, and are not in the public domain (unless the authors specifically state that they wish the messages to be in the public domain).
