Survey Understanding Public's Opinion

    There has never been a large-scale survey in Israel about synthetic biology and genetic engineering. Therefore, our first step was to undertake a massive public opinion survey to learn about the current state of public opinion, and hopefully understand the roots of opposition to synthetic biology.

    In the past few years, a number of public opinion surveys have been undertaken in various countries regarding new biological technologies, including synthetic biology. We based our survey on the strong, high-quality foundations of past efforts from across the world, including studies done in the United States, the United Kingdom, Japan, and New Zealand.

    Two questions must be asked before presenting the questionnaire and the results: Why bother conducting such a survey? And what did we intend to learn from it?

    We wanted to canvass Israeli public opinion about synthetic biology because first of all, we couldn’t find any similar survey done in the past in Israel, and secondly, scientific progress tends to outpace public perception. We believe synthetic biology holds great potential for ecological, medical, and other projects, but nothing can be implemented without public support. For that to happen, we first need to understand how much people know about genetic engineering and synthetic biology, and what their concerns and thoughts are.

    *Note: as the term "synthetic biology" is not very common, we added the term "genetic engineering" which is much more familiar, even though they are not completely equivalent.

    The Questionnaire



    Ten questions were translated to Hebrew from the surveys mentioned above, some slightly modified to be more comprehensive and generic. In addition, one question was added that relates to our project specifically. The personal details asked were minimal, to make the survey as convenient and fluent as possible, and included: age, gender, religion & education.

    Read the full survey in English.



    Methods of distribution



    The questionnaire was distributed from September 8th to September 24th, 2013, in the following ways:

    1. Link in an article about our team, posted on the Israeli news website "Ynet". => 120 responses.
    2. Hard copy surveys handed out in the "Science Night Festival" in Beer Sheva. => 50 responses.
    3. Science forums. => 234 responses.
    4. Facebook link, distributed by team members and posted on several Israeli forums. => 711 responses. 13 out of them belong to "green" forums and are marked seperatly.

    Altogether we collected 1115 responses (!) for our survey, from a variety of age groups and backgrounds, 77 of which were excluded due to many missing answers.

    Do the responders accurately represent Israeli society? Unfortunately, no. We tried to reach a diverse sample of Israelis but as seen above, most responders were ones that reached the link via Facebook, which is skewed to be a younger and more technologically savvy population. Also, because we are all students and because we used science forums to promote the survey, the percentage of people with an academic background or advanced degrees that answered our survey is higher than in general population.

    Because the results of this survey are not necessarily representative, we focused on directed analysis of the groups that we do feel that our results represent, rather than generalizations about all of Israeli society. We also excluded the responses from the science forum links for some of the analyses. For a fuller picture, we recommend generating an even larger survey using survey companies that have better access to a more representative sample of the public.


    Results & Analysis



    Our hypothesis is that the more people hear and learn about the world of genetic engineering and synthetic biology, the less they are concerned about it. The encounters with this field could be through an article in a newspaper, studying about it in school, talking about it with friends, watching a video on Youtube, etc. In our eyes, the negative public perception and uncertainty about biological developments has a lot to do with a lack of familiarity with the subject and a lack of participation in public discourse about it.

    We present below the results most relevant to our hypothesis. The full report can be found here and contains many interesting graphs, which illustrate the differences between our religious responders to our secular ones, gender differences in attitudes, and more.


    1. Have you ever heard of synthetic biology?




    2. Have you ever heard of genetic engineering?



    Unlike the term "synthetic biology," "genetic engineering" is relatively well-known: this is not surprising considering that the field of genetic engineering has been around decades longer than synthetic biology. This could actually be an advantage, because it indicates that there is still potential to shape people’s perceptions of synthetic biology, whereas this may be more challenging for genetic engineering.



    3. What are the first things that come to mind when you hear the term ”genetic engineering”?



    This question was a free response section, and we created a world cloud with the responses (the largest words appeared most often). From the results, it is obvious that out of all of the applications and projects in genetic engineering, what most captured the public imagination is cloning and Dolly the sheep. If this result repeats itself in a larger-scale survey, it would be interesting to attempt to analyze what it is about the Dolly story that resonated with people, and whether it hurt or helped opinions about genetic engineering.



    4. Assuming that you have heard of synthetic biology or genetic engineering, where did you hear about it?



    All groups encountered the topic of "genetic engineering" in a wide variety of contexts. Nevertheless, small differences can be seen: responders from the science forums are much more active in science blogs online, while responders from the general links heard the term more on television than others.



    5. In the sources you were exposed to, do you feel that the subject was covered in a positive or negative manner?




    6. In your opinion, do the benefits and usefulness of genetic engineering outweigh the risks?



    As expected, responders active in "green" forums are more concerned about the risks of genetic engineering than other groups. Also, it is clear that people with a scientific background tend to be more supportive. Generally speaking, ˜50% of the population we surveyed believes that benefits outweigh risks.




    This graph strengthens our hypothesis: the more people are informed about GE, the less they are concerned about risks. This might mean that the actual risks are less significant than what people who are not informed imagine. Or, it may be that perception of the risks stays the same, but when people are more informed about the benefits of GE, they feel that overall the benefits outweigh the risks.



    7. How much do you identify with each of the following concerns?



    *Note: we excluded the responses of the science forums here to get a picture that is closer to the general public perception in Israel.

    Taking a closer look at the ethical concern we mentioned in question 7 of the survey, we can see below that higher education level correlates with fewer concerns.





    8. For each of the following uses of genetic engineering: in your opinion, is it a positive development that makes you optimistic, or a negative development that makes you concerned?



    So far we discussed the field of synthetic biology in general, but perhaps people feel differently about different applications? Indeed, support is much higher for environmental applications such as biological fuel or the cleaning of oil spills, and significantly lower for engineered food products. To determine why will require follow-up research, but it seems that one obvious factor is that people are more concerned about things that will affect them on a personal level. Interestingly, for the medical application of disease identification, this did not hold true: most saw this as a positive development. Perhaps people are willing to accept scientific developments for the sake of health; or they are more used to “non-natural” treatments; or trust the medical industry more than the food industry. In any case, it seems that perhaps for now, the public is not ready for the use of synthetic biology in the food industry.

    The following graphs focus on three specific applications, and once again show that knowledge and familiarity correspond to a more favorable perception of various synthetic biology applications.









    9. If it were possible to create a control mechanism for engineered bacteria, which would make sure that the bacteria destroyed themselves immediately after the completion of their intended purpose in nature, would the use of bacteria with this mechanism reduce your concerns?




    Conclusion



    We have seen similar results in past surveys regarding synthetic biology in other countries, indicating a strong correlation between familiarity and knowledge and the degree of positive perception of the field. Using the conclusions from the survey, we directed our outreach efforts towards basic education about the field of synthetic biology to various populations, who might not be exposed to reliable information on the subject (see our Outreach section for details). We also attempted to address the concerns raised in the free-response sections from the survey in our Bioethics Q&A. In the future, a better sample of the population must be reached to increase data integrity and more importantly, efforts should be put in understanding not only what people feel, but also why.

    In forming and analyzing this survey, we were greatly supported by Dr. Roey Tzezana from the Unit for Technology and Society Foresight at Tel Aviv University, who is currently planning a broader study about public perception of synthetic biology. We hope that our results will serve as a basis and proof of concept for further work, and look forward to hear and learn more about public opinion in Israel.
