The risk of normative bias in reporting empirical research: lessons learned from prenatal screening studies about the prominence of acknowledged limitations

Empirical data can be an extremely powerful and influential tool in bioethical research. However, when researchers or policy makers look for answers to ethical questions by engaging with empirical research, there can be a tendency (conscious or unconscious) to shape, report, and use empirical research in a way that confirms their own preferred ethical conclusions. This skewing effect - what we call 'normative bias' - is often so subtle it falls short of clear misconduct and thus can be difficult to call out. However, we argue that this subtle influence of bias has the potential to significantly influence debate and policy around highly sensitive ethical issues and must be guarded against. In this paper we share the lessons we have learned through a journey of self-reflection around the effect that normative bias can have when reporting on and referring to empirical data relating to ethical issues. We use a variety of papers from our area of the ethics of routine prenatal screening to illustrate these subtle but often powerfully distorting effects of bias. Our aim in doing so is not to criticise the work of others, as we recognise our own normative bias, but to improve awareness of this issue, remind the need for reflexivity to guard against our own biases, and introduce a new criterion - the idea of a 'limitation prominence assessment' - that can work as a practical way to evaluate the seriousness of the limitations of an empirical study and thus, the risks of the study being misread or misinterpreted through superficial reading.

Mapping, framing, shaping: a framework for empirical bioethics research projects

Background

There is growing interest in the use and incorporation of empirical data in bioethics research. Much of the recent focus has been on specific “empirical bioethics” methodologies, which attempt to integrate the empirical and the normative. Researchers in the field are, however, beginning to explore broader questions, including around acceptable standards of practice for undertaking such research.

The framework:

In this article, we further widen the focus to consider the overall shape of an empirical bioethics research project. We outline a framework that identifies three key phases of such research, which are conveyed via a landscaping metaphor of Mapping-Framing-Shaping. First, the researcher maps the field of study, typically by undertaking literature reviews. Second, the researcher frames particular areas of the field of study, exploring these in depth, usually via qualitative research. Finally, the researcher seeks to (re-)shape the terrain by issuing recommendations that draw on the findings from the preceding phases. To qualify as empirical bioethics research, the researcher will utilise a methodology that seeks to bridge these different elements in order to arrive at normative recommendations. We illustrate the framework by citing examples of diverse projects which broadly adopt the three-phase framework. Amongst the strengths of the framework are its flexibility, since (as the examples indicate) it does not prescribe any specific methods or particular bridging methodology. However, the framework might also have its limitations, not least because it appears particularly to capture projects that involve qualitative – as opposed to quantitative – research.

Conclusions

Despite its possible limitations, we offer the Mapping-Framing-Shaping framework in the hope that this will prove useful to those who are seeking to plan and undertake empirical bioethics research projects.

An update on the "empirical turn" in bioethics: analysis of empirical research in nine bioethics journals

Background

A review of literature published a decade ago noted a significant increase in empirical papers across nine bioethics journals. This study provides an update on the presence of empirical papers in the same nine journals. It first evaluates whether the empirical trend is continuing as noted in the previous study, and second, how it is changing, that is, what are the characteristics of the empirical works published in these nine bioethics journals.

Method

A review of the same nine journals (Bioethics; Journal of Medical Ethics; Journal of Clinical Ethics; Nursing Ethics; Cambridge Quarterly of Healthcare Ethics; Hastings Center Report; Theoretical Medicine and Bioethics; Christian Bioethics; and Kennedy Institute of Ethics Journal) was conducted for a 12-year period from 2004 to 2015. Data obtained was analysed descriptively and using a non-parametric Chi-square test.

Results

Of the total number of original papers (N = 5567) published in the nine bioethics journals, 18.1% (n = 1007) collected and analysed empirical data. Journal of Medical Ethics and Nursing Ethics led the empirical publications, accounting for 89.4% of all empirical papers. The former published significantly more quantitative papers than qualitative, whereas the latter published more qualitative papers. Our analysis reveals no significant difference (χ2 = 2.857; p = 0.091) between the proportion of empirical papers published in 2004–2009 and 2010–2015. However, the increasing empirical trend has continued in these journals with the proportion of empirical papers increasing from 14.9% in 2004 to 17.8% in 2015.

Conclusions

This study presents the current state of affairs regarding empirical research published nine bioethics journals. In the quarter century of data that is available about the nine bioethics journals studied in two reviews, the proportion of empirical publications continues to increase, signifying a trend towards empirical research in bioethics. The growing volume is mainly attributable to two journals: Journal of Medical Ethics and Nursing Ethics. This descriptive study further maps the still developing field of empirical research in bioethics. Additional studies are needed to completely map the nature and extent of empirical research in bioethics to inform the ongoing debate about the value of empirical research for bioethics.

The use of empirical research in bioethics: a survey of researchers in twelve European countries

BACKGROUND

The use of empirical research methods in bioethics has been increasing in the last decades. It has resulted in discussions about the 'empirical turn of bioethics' and raised questions related to the value of empirical work for this field, methodological questions about its quality and rigor, and how this integration of the normative and the empirical can be achieved. The aim of this paper is to describe the attitudes of bioethics researchers in this field towards the use of empirical research, and examine their actual conduct: whether they use empirical research methods (and if so, what methods), and whether (and how) they have made attempts at integrating the empirical and the normative.

METHODS

An anonymous online survey was conducted to reach scholars working in bioethics/biomedical ethics/ethics institutes or centers in 12 European countries. A total of 225 bioethics researchers participated in the study. Of those, 200 questionnaires were fully completed, representing a response rate of 42.6%. The results were analysed using descriptive statistics.

RESULTS

Most respondents (n = 175; 87.5%) indicated that they use or have used empirical methods in their work. A similar proportion of respondents (61.0% and 59.0%) reported having had at least some training in qualitative or quantitative methods, respectively. Among the 'empirical researchers', more than a fifth (22.9%) had not received any methodological training. It appears that only 6% or less of the 'empirical researchers' considered themselves experts in the methods (qualitative or quantitative) that they have used. Only 35% of the scholars who have used empirical methods reported having integrated empirical data with normative analysis, whereas for their current projects, 59.8% plan to do so.

CONCLUSIONS

There is a need to evaluate the current educational programs in bioethics and to implement rigorous training in empirical research methods to ensure that 'empirical researchers' have the necessary skills to conduct their empirical research in bioethics. Also imperative is clear guidance on the integration of the normative and the empirical so that researchers who plan to do so have necessary tools and competences to fulfil their goals.
