Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores were younger age and female sex in the United States, and male sex in Mali. Scores in the United States were higher than in Mali (P = 0.005). Despite this difference participants at both sites were well informed overall. Although interpretation must be qualified because questionnaires were not intended as research tools and were not standardized among sites, these results do not support concerns about systematic low understanding among research participants in developing versus developed countries.

In this paper we analyze the non-coercive ways in which researchers can use knowledge about the decision-making tendencies of potential participants in order to motivate them to consent to research enrollment. We identify which modes of influence preserve respect for participants’ autonomy and which disrespect autonomy, and apply the umbrella term of manipulation to the latter. We then apply our analysis to a series of cases adapted from the experiences of clinical researchers in order to develop a framework for thinking through the ethics of manipulating people into research participation. All manipulation disrespects autonomy and is therefore pro tanto wrong. However, only deceptive manipulation invalidates the consent that results from it. Use of the other forms of manipulation can be permissible, but only if the outcome of using manipulation is sufficiently good and if the research cannot be carried out using ethically preferable means to obtain consent.

Most regulations and guidelines require that potential research participants be told a great deal of information during the consent process. Many of these documents, and most of the scholars who consider the consent process, assume that all this information must be disclosed because it must all be understood. However, a wide range of studies surveying apparently competent participants in clinical trials around the world show that many do not understand key aspects of what they have been told. The standard view of the conditions for valid consent therefore implies that these people have failed to give valid consent to research participation. In this paper we argue that the standard view is false. The primary function of the requirement that researchers disclose information about a study is the avoidance of illegitimate control over someone’s consent decision, which is a form of fraud.We derive the content and manner of appropriate disclosure by analysing the ways in which the manipulation of information can invalidate consent. Our analysis shows that the informational requirements for valid consent are conceptually distinct and thus unlikely to have identical contents. This implies that consent can be valid when not everything that ought to be disclosed by the person asking for consent is understood by the person who proffers it.

The U.S. review system for human subjects research has been widely criticized in recent years for requirements that delay research without improving human subjects protections. Any major reformulation of regulations may take some time to implement. In the meantime, current regulations often allow for streamlined ethics review without jeopardizing—and possibly improving—protections for research participants. We discuss underutilized options, including research that need not be classified as “human subjects research,” categories of studies that can be exempt from ethical review, and studies that need only undergo expedited review by one IRB member. In addition, we consider ways to simplify review of multi-center research using one institution’s IRB. We speculate on multiple reasons for the underuse of these mechanisms, and exhort IRBs and researchers to take advantage of these important opportunities to improve the review process.

Most bioethicists who address questions to which global justice matters have not considered the significance of the disputes over the correct theory of global justice. Consequently, the significance of the differences between theories of global justice for bioethics has been obscured. In this paper, I consider when and how these differences are important. I argue that certain bioethical problems can be resolved without addressing disagreements about global justice. People with very different views about global justice can converge on the existence of a duty to aid the very badly off — those in absolute poverty — wherever they may be. However, despite agreement on extreme cases, there should be disagreement over the extent of international obligations to those who are only relatively poor. Consequently, different theories of justice will diverge in their implications for a number of important problems in contemporary bioethics. I close by sketching in more detail two contemporary bioethical issues —concerning pharmaceutical patents and the health worker brain drain —and show how responses to them might be developed by cosmopolitan and statist liberals.
