Societal Challenges facing Synthetic Biology

I believe one of the biggest challenges facing Synthetic biology are excessive promises. Quotes such as “Synthetic biology has been predicted to heal us, feed us and fuel us.” (Milestones in synthetic (micro-) biology, 2014) will in time produce more harm than good. The ridiculous expectations from Synthetic biology are further fuelled by more promises from scientists and attempts to secure funding. These high expectations and slow delivery on them due to technical problems will eventually lead to some kind of backlash.
Additionally it seems that many scientists have already decided that the public is the “enemy”. In wanting to prevent the public opinion backlash which happened to previous fields such as stem cell research or GMO companies many scientists have decided to be proactive this time. However many have taken to the view that the general public is ignorant or uninformed and their opposition to some field of science stems from this (the now discredited ‘Deficit Model’). It seems many scientists have decided on the public as some obstacle for the above mentioned promise and vision for Synthetic Biology.

Public perceptions and fears of synthetic biology may obstruct research in this field, in a similar fashion to GM. This has been recognised by all stakeholders and public engagement and dialogue activities are in the process of being developed.” (EPSRC, 2009, p. 46) 

This somewhat arrogant view that scientists should know better than the public what is and isn’t to their benefit is encountered among some scientists. And indeed when it comes to communication with the general public, scientists tend to be most concerned with informing people about the potential benefits and attempting to stop people from overblowing the risks. It is a rare afterthought on whether the public should be involved in the discussion on the potential benefits concerning them. 
Instead however it seems that the general public is overall sympathetic to the goals of synthetic biology and shows understanding of balancing potential risks with potential benefits. When involved in discussion with scientists selected members of the public were both excited about the opportunities as well as concerned about risks. From these workshops (carried out in 2010) five central questions emerged: “What is the purpose? Why do you want to do it? What are you going to gain from it? What else is it going to do? How do you know you are right?” (Synthetic Biology Dialogue Report, 2010)  

I believe that these are important questions that scientists will have to face and should consider when approaching projects and deciding on their research.
Even in terms of regulations members of the public were generally sympathetic. There were acknowledgements that oftentimes risks are unforeseeable and uncontrollable and accidents do happen, however most were strongly against releasing synthetic organisms in the wild as well as generally recommending a cautious approach. One concern people showed was that regulation would not be able to keep up with scientific advancement, although I believe personally that this is less of an issue than people think. On the other hand there was also a belief that too harsh of a regulation would stifle creativity and advancement and rob society of potential benefits. Parallels with stem cell research were brought up.

There were also concerns regarding the “creation of life”, although the general consensus seems to be that if the benefits outweigh risks this was acceptable. In general humility was appreciated, especially in the context of synthetic life. 
There are however some concerns that members of the public hold which are based on misinformation. For example one misconception is that the supposed “de-skilling” of biology together with the free availability of genomic sequences of pathogenic organisms and the relative cheapness of DNA synthesis will allow people to operate outside of professional research laboratories, allowing for some form of “bio-terrorism”. 

 A more realistic understanding of the research and the extensive knowledge required and our own lack of standardised practices in science puts any kind of risk from the misuse of de-skilled biology decades if not more into the future. 
In general I believe societal challenges are much less serious than a lot of scientists believe. In fact people will generally be supportive, and there are indeed a lot of benefits to be gained from Synthetic Biology. I believe that people are much more scared of non-governmental organisations and big Pharmaceutical companies and their involvement in Synthetic Biology than they are of basic research being done by academic institutions. 

The strawman of an uninformed and irrational public, with strong for or against views on science, and demands for 0-risk science, which has been built up in the mind of some scientists is more dangerous to public opinion than almost anything else. If anything this way of thinking will need to stop.

As with all emerging scientific fields there is a need to maintain a level of trust with the general public as well as policy regulators. Excessive hype and exaggeration over potential benefits are counterproductive for this, and instead the field as a whole will need to focus on the development of ethical models of regulation, which allow technological progress and direct it in a way that will yield the most benefit to humans and society
