Peer review policy

Jan only reviews for journals that adopt a 'wide open access' (WOA) approach. This approach consists in peer-reviewed journals being prepared to publish all articles that survive scientific scrutiny through an appropriate peer-review process, regardless of the author's ability or willingness to pay. Ideally, papers submitted by those authors who cannot or will not pay should also be published as 'open access articles'.  


• BA's and MA's in Philosophy, Religious Studies, and Theology (Catholic University of Leuven, 1990-1997)

• Teacher Training Programme (Catholic University of Leuven, 1995)

• PhD (University of St Andrews, dissertation title: ‘The Scientific Basis for an Ecological Ethic in the Context of Process Thought’, 2001)

• Fellow, Higher Education Academy (2013)

II. Current work

1. Public health ethics, law, and the consumption of animal products

The GHI (Global Health Impact) concept plays a pivotal role in Jan's bioethical theory. The GHI is a unit of measurement that evaluates the impacts of human actions on the health of all biological organisms. The theory is introduced in the article Negative 'GHIs', the Right to Health Protection, and Future Generations. Journal of Bioethical Inquiry 2011, 8(2), 165-176. In this paper, Jan argues that the negative GHIs of many people who live today violate the right to health protection of future generations. Consequently, it is argued that many people must reduce their negative GHIs.

Recent work, facilitated by a grant from the Wellcome Trust, focuses on evaluating the positive and negative GHIs associated with the human consumption of animal products, partly by comparing traditional with more novel versions, including ‘lab-grown flesh’. The most extensive treatment is in the book ‘Animal (De)liberation. Should the Consumption of Animal Products Be Banned? London: Ubiquity Press, 2016’, available at

A recent chapter compares the negative and positive GHIs of people who consume animal products in different socio-ecological contexts, notably the Maasai and Scots. It will be published as: Deckers, J. Could Ecologically Sound Human Nutrition Include the Consumption of Animal Products?, in: Joan Sabate (ed). Environmental Nutrition. Connecting health and nutrition with sustainable diets. Elsevier, 2019, in press.

Another chapter focuses in particular on the role played by novel technologies, including lab-grown flesh. See: Linnea Laestadius, Jan Deckers, and Stephanie Baran, Food crimes, harms, and carnist technologies. In: Allison Gray and Ronald Hinch (eds.). A handbook of food crime. Immoral and illegal practices in the food industry and what to do about them, Bristol: Policy Press, 2018, chapter 18.

Using the example of Australia, the negative GHIs of the farm animal sector in relation to obesity are examined in Obesity, Public Health, and the Consumption of Animal Products. Ethical Concerns and Political Solutions. Journal of Bioethical Inquiry 2013, 10(1), 29-38.

The negative GHIs of the sector in relation to human hunger are explored in Does the consumption of farmed animal products cause human hunger?. Journal of Hunger and Environmental Nutrition 2011, 6(3), 353-377.

The negative GHIs of the sector in relation to human disease are examined in: Could some people be wronged by contracting swine flu? A case discussion on the links between the farm animal sector and human disease. Journal of Medical Ethics 2011, 37(6), 354-356.

The negative GHIs of the sector in relation to climate change and a range of other environmental issues are the subject of two further papers: Should the consumption of farmed animal products be restricted, and if so, by how much?. Food Policy 2010, 35 (6), 497-503; Justice, Negative GHIs, and the Consumption of Farmed Animal Products. Journal of Global Ethics 2011, 7(2), 205-216

The policy options that are available to curtail the negative GHIs associated with the consumption of farmed animal products are discussed in: What Policy Should Be Adopted to Curtail the Negative GHIs Associated with the Consumption of Farmed Animal Products?. Res Publica 2010, 16(1), 57-72.


2. The use of AI for moral enhancement

Work in this area has been developed through collaboration with Francisco Lara, Universidad de Granada. Some have suggested that genetic biotechnologies could and ought to be used to make human beings more moral. We consider that these proposals are problematic. However, we argue in this paper that the use of another new technology, AI, would be preferable to achieve this goal. Whilst several proposals have been made on how to use AI for moral enhancement, we present an alternative that we argue to be superior to other proposals that have been developed. For our proposal to develop a Socratic assistant for AIenhancement, see: Lara F, Deckers J. Artificial Intelligence as a Socratic Assistant for Moral Enhancement. Neuroethics 2019,


3. The ethics and law of embryo research

The paper 'An Analysis of the Arguments Underpinning UK Embryonic Stem Cell Legislation on the Embryo’s Status' (Journal of Stem Cells 2007, 2 (1) 47-62) presents Jan's most comprehensive account on the debate on embryonic stem cell research. It engages directly, and comprehensively, with the arguments on the status of the embryo that have been used in UK Parliament and in the reports published by their chief advisors in the debate on embryonic stem cell research preceding the introduction of the Human Fertilisation and Embryology (Research Purposes) Regulations 2001. The article has been reprinted, and is available from


4. The ethics and law of abortion

A paper with the title 'The right to life and abortion legislation in England and Wales: A proposal for change' was published in Diametros (2010, 26, 1-22). It proposes amending the law on abortion in England and Wales. It can be accessed here:


5. The ethics of deliberation, and genetic engineering

In a project on 'Deliberating the Environment: Scientists and the Socially Excluded in Dialogue' (funded by ESRC Science in Society Programme; Project team: Derek Bell, Mary Brennan, Jan Deckers, Tim Gray, Nicola Thompson) we explored the potential of a novel institutional mechanism, the ‘deliberative exchange’, to facilitate mutual learning between two disparate social groups. We defined a ‘deliberative exchange’ as a one-to-one deliberation between two persons from different social groups facilitated by a researcher in which the participants work collaboratively to consider and address important ethical and policy issues. The participants were persons from low income households and academic scientists. Each participant participated in a series of deliberative exchanges in which he or she was invited to discuss different environmental issues. The project had two related aims. Firstly, to explore the potential of the deliberative exchange as a method for facilitating and studying mutual learning between individuals with different backgrounds and experience. Secondly, to study the process of deliberation between persons from low-income households and academic scientists and the effects that such deliberation has on the participants. The final report can be read here:

Participants’ views on genetic engineering are published in:
