Empirical research on research ethics

Ethics is normative; ethics indicates, in broad terms, what researchers should do. For example, researchers should respect human participants. Empirical study tells us what actually happens. Empirical research is often needed to fine-tune the best ways to achieve normative objectives, for example, to discover how best to achieve the dual aims of gaining important knowledge and respecting participants. Ethical decision making by scientists and institutional review boards should not be based on hunches and anecdotes (e.g., about such matters as what information potential research participants would want to know and what they understand, or what they consider to be acceptable risks). These questions should be answered through empirical research. Some of the preceding articles in this special issue illustrate uses of empirical research on research ethics. This article places empirical research on research ethics into broader perspective and challenges investigators to use the tools of their disciplines to proactively solve ethical problems for which there currently exist no empirically proven solutions.     

Integrating brain science research with intelligence research

Understanding the possible causes of differences in intelligence is crucial if children are to achieve their full potential. Such understanding has been hampered until recently, however, because researchers who study intelligence have neglected recent findings in the brain sciences suggesting that the brain develops in response to environmental stimulation. These findings have seemed to contradict intelligence research that suggests that intellectual abilities are inherited. However, the findings from intelligence research and the brain sciences can be integrated if it is accepted that there are individual differences in the process by which the brain adapts to the environment, such that some people's brains are better at adapting than others'. The findings obtained from intelligence research are consistent with this integrated model. Such an integration has implications for better understanding the nature of intelligence.     

Honest research

The origins of research projects, the duties of supervisors and research workers, the subjective elements in research and the difficulties of publication are reviewed, as a guide to the complexities of executing an honest research project. It is assumed that research carried out with maximal intellectual integrity will result in real advances.
