I’ve mentioned in the previous posts about the introduction and conclusions chapters in the book “Citizen Science: Innovation in Open Science, Society and Policy” and the chapter about citizen science in universities. The final chapter in the book that I would like to highlight is my chapter “participatory citizen science“. As Rick Bonney pointed to me, on the face of it, this title sounds like a pointless repetition because all citizen science is participatory science by definition, and therefore this title can be translated to “participatory participatory science” – which doesn’t make much sense…
However, I contend that it does make sense because the issue of participation in citizen science and “what exactly the word participation mean?” is not that simple to answer. A good demonstration the fact that participation is not that simple is provided through to frequent references to Arnstein ladder of citizen participation in the literature on citizen science. It is something that I have been exploring in various papers and in my research. The chapter itself is a polished, peer-reviewed, version of my keynote from the ECSA 2016 conference (and the blog that accompanied it). It is an investigation into the meaning of participation and starting to answer who participate and how they participate. The chapter leads towards a 2×2 typology of the type of participants and the depth of engagement across projects.
The highlights of the chapter are:
- Common conceptualisations of participation assume high-level participation is good and low-level participation is bad. However, examining participation in terms of high and low levels of knowledge and engagement reveals different types of value in each case.
- The spectrum of citizen science activities means some are suitable for people who have education and knowledge equivalent to PhD level, while some are aimed at non-literate participants. There are also activities suitable for micro-engagement, and others requiring deep engagement over time.
- Issues of power, exploitation and commitment to engagement need to be explored for each citizen science project, as called for by the ECSA Ten Principles of Citizen Science, in response to the need for a more nuanced view that allows different activities to emerge
One of the aspects that fascinates me about citizen science and crowdsourcing is the nature of participation and in particular participation inequality. As I’ve noted last week, when you look at large scale systems, you expected to see it in them (so Google Local Guides is exhibiting 95:5:0.005 ratio).
I knew that this phenomenon has been observed many times in Massive Online Open Courses (MOOCs) so I expected it to happen in the course. I’m particularly interested in the question of the dynamic aspect of participation inequality: for example, at the point of the beginning of the “introduction to citizen science and scientific crowdsourcing” course, every single person is at exactly the same level of participation – 0. However, within three weeks, we are starting to see the pattern emerges. Here are some of the numbers:
At this point in time, there are 497 people that went through the trouble of accessing UCLeXtend and creating a profile. They are a small group of the people that seen the blog post (about 1,100) or the tweet about it (about 600 likes, retweets or clicking on the link). There are further 400 people that filled in the online form that I set before the course was open and stated their interest in it.
The course is structured as a set of lectures, each of them broken into segments of 10 minutes each, and although the annotated slides are available and it is likely that many people prefer them over listening to a PowerPoint video (it’s better in class!), the rate of viewing of the videos gives an indication of engagement.
Here are our viewing statistics for now:
We can start seeing how the sub-tasks (viewing a series of videos) is already creating the inequality – lots of people watch part of the first video, and either give up (maybe switching to the notes) or leaving it to another time. By part 4 of the first lecture, we are already at very few views (the “Lecture 3 Part 2” video is the one that I’ve integrated in the previous blog post).
What is interesting to see is how fast participation inequality emerges within the online course, and notice that there is now a core of about 5-10 people (about 1% to 2%) that are following the course at the same rate as the 9 students who are in the face to face class. I expect people to also follow the course over a longer period of time, so I wouldn’t read too much into the pattern and wait until the end of the course and a bit after it to do a full analysis.
When I was considering setting up the course as a hybrid online/offline, I was expecting this, since the amount of time that is required to follow up the course is nearly 4-5 hours a week – something reasonable for an MSc student during a course, but tough for a distance learner (I have a huge appreciation to these 10 people that are following!).
‘Citizen Science as Participatory Science‘ is one of the most popular posts that I have published here. The post is the core section of a chapter that was published in 2013 (the post itself was written in 2011). For the first European Citizen Science Association conference I was asked to give a keynote on the second day of the conference, which I have titled ‘Participatory Citizen Science‘, to match the overall theme of the conference, which is ‘Citizen Science – Innovation in Open Science, Society and Policy’. The abstract of the talk:
In the inaugural ECSA conference, we are exploring the intersection of innovation, open science, policy and society and the ways in which we can established new collaborations for a common good. The terms participation and inclusion are especially important if we want to fulfil the high expectations from citizen science, as a harbinger of open science. In the talk, the conditions for participatory citizen science will be explored – the potential audience of different areas and activities of citizen science, and the theoretical frameworks, methodologies and techniques that can be used to make citizen science more participatory. The challenges of participation include designing projects and activities that fit with participants’ daily life and practices, their interests, skills, as well as the resources that they have, self-believes and more. Using lessons from EU FP7 projects such as EveryAware, Citizen Cyberlab, and UK EPSRC projects Extreme Citizen Science, and Street Mobility, the boundaries of participatory citizen science will be charted.
As always, there is a gap between the abstract and the talk itself – as I started exploring the issues of participatory citizen science, some questions about the nature of participation came up, and I was trying to discuss them. Here are the slides:
After opening with acknowledgement to the people who work with us (and funded us), the talk turn the core issue – the term participation.
Type ‘participation’ into Google Scholar, and the top paper, with over 11,000 citations, is Sherry Rubin Arnstein’s ‘A ladder of citizen participation’. In her ladder, Sherry offered 8 levels of participation – from manipulation to citizen control. Her focus was on political power and the ability of the people who are impacted by the decisions to participate and influence them. Knowingly simplified, the ladder focus on political power relationships, and it might be this simple presentation and structure that explains its lasting influence.
These ladders come with baggage: a strong value judgement that the top is good, and the bottom is minimal (in the version above) or worse (in Arnstein’s version). The WeGovNow! Project is part of the range of ongoing activities of using digital tools to increase participation and move between rungs in these concept of participation, with an inherent assumption about the importance of high engagement.
At the beginning of 2011, I found myself creating a ladder of my own. Influenced by the ladders that I learned from, the ‘levels of citizen science’ make an implicit value judgement in which ‘extreme’ at the top is better than crowdsourcing. However, the more I’ve learned about citizen science, and had time to reflect on what participation mean and who should participate and how, I feel that this strong value judgement is wrong and a simple ladder can’t capture the nature of participation in Citizen Science.
There are two characteristics that demonstrate the complexity of participation particularly well: the levels of education of participants in citizen science activities, and the way participation inequality (AKA 90-9-1 rule) shape the time and effort investment of participants in citizen science activities.
We can look at them in turns, by examining citizen science projects against the general population. We start with levels of education – Across the EU28 countries, we are now approaching 27% of the population with tertiary education (university). There is wide variability, with the UK at 37.6%, France at 30.4%, Germany 23.8%, Italy 15.5%, and Romania 15%. This is part of a global trend – with about 200 million students studying in tertiary education across the world, of which about 2.5 million (about 1.25%) studying to a doctoral level.
However, if we look at citizen science project, we see a different picture: in OpenStreetMap, 78% of participants hold tertiary education, with 8% holding doctoral level degrees. In Galaxy Zoo, 65% of participants with tertiary education and 10% with doctoral level degrees. In Transcribe Bentham (TB), 97% of participants have tertiary education and 24% hold doctoral level degrees. What we see here is much more participation with people with higher degrees – well above their expected rate in the general population.
The second aspect, Participation inequality, have been observed in OpenStreetMap volunteer mapping activities, iSpot – in both the community of those who capture information and those that help classify the species, and even in an offline conservation volunteering activities of the Trust for Conservation Volunteers. In short, it is very persistent aspect of citizen science activities.
For the sake of the analysis, lets think of look at citizen science projects that require high skills from participants and significant engagement (like TB), those that require high skills but not necessarily a demanding participation (as many Zooniverse project do), and then the low skills/high engagement project (e.g. our work with non-literate groups), and finally low skills/low engagement projects. There are clear benefits for participation in each and every block of this classification:
high skills/high engagement: These provide provide a way to include highly valuable effort with the participants acting as virtual research assistants. There is a significant time investment by them, and opportunities for deeper engagement (writing papers, analysis)
high skills/low engagement: The high skills might contribute to data quality, and allow the use of disciplinary jargon, with opportunities for lighter or deeper engagement to match time/effort constraints
low skills/high engagement: Such activities are providing an opportunity for education, awareness raising, increased science capital, and other skills. They require support and facilitation but can show high potential for inclusiveness.
low skills/low engagement: Here we have an opportunity for active engagement with science with limited effort, there is also a potential for family/Cross-generational activities, and outreach to marginalised groups (as OPen Air Laboratories done)
In short – in each type of project, there are important societal benefits for participation, and it’s not only the ‘full inclusion at the deep level’ that we should focus on.
Interestingly, across these projects and levels, people are motivated by science as a joint human activity of creating knowledge that is shared.
So what can we say about participation in citizen science – well, it’s complex. There are cases where the effort is exploited, and we should guard against that, but outside these cases, the rest is much more complex picture.
The talk move on to suggest a model of allowing people to adjust their participation in citizen science through an ‘escalator’ that we are aiming to conceptually develop in DITOs.
Finally, with this understanding of participation, we can understand better the link to open science, open access and the need of participants to potentially analyse the information.
