Citizen science as a means for increasing public engagement in science: presumption or possibility?
Victoria Y. Martin1,2
Citizen science is often assumed to increase public science engagement, however little is
known about who is likely to volunteer and the implications for greater societal impact. This
study segments 1145 potential volunteers into six groups according to their current
engagement in science (EiS). Results show groups with high levels of EiS are significantly
more interested in volunteering and more likely to participate in various research roles than
those with lower EiS scores. While citizen science benefits some in science and society, its
use as a strategy to bring about positive shifts in public science engagement needs to be
reconsidered.

Introduction
The disciplinary discourse, policy and practice of science communication has seen the push
for public understanding of science shift to a push for public engagement in science (Davies,
2013; Irwin, 2014; Selin et al., 2016; Stilgoe, Lock, & Wilsdon, 2014). Although public
engagement in science (PES) has many different meanings in many different contexts 1Southern Cross University, Lismore, New South Wales, Australia2Cornell University, Ithaca, NY, USA

(discussed below), a scientifically engaged society is seen as essential for delivering
democratic science governance and decision-making, and empowering individuals and
communities to be aware of, and able to use science in their everyday lives (Árnason, 2013;
Bickerstaff, Lorenzoni, Jones, & Pidgeon, 2010; Irwin, 1995, 2014). How deeply an
individual is engaged in science has implications for their ability to make scientifically-
informed decisions (Irwin, 1995; Phillips, Carvalho, & Doyle, 2012) about issues such as
nanotechnology (Anderson, Delborne, & Kleinman, 2013; Powell & Lee Kleinman, 2008),
genetically modified food (Irwin, 2006; Nielsen, Lassen, & Sandøe, 2011), vaccinations
(Kata, 2012), and climate change (Jaspal, Nerlich, & van Vuuren, 2015). For these reasons,
governments and scientific organizations across the globe are supporting activities to improve
the public’s relationship with science (see, for example: the public engagement goals of the
EU's "Horizon 2020", www.ec.europa.eu/programmes/horizon2020; the USA’s Center for
Public Engagement with Science & Technology, www.aaas.org/pes/what-public-engagement;
and Australia’s national science engagement strategy, www.inspiringaustralia.net.au).
One method for the public to engage directly is citizen science, which describes research
projects that involve volunteers in some capacity during the scientific process. This paper
investigates the link between public willingness to participate in citizen science and the
impact this is likely to have on the public’s broader engagement in science. Placed in the
context of marine science in Australia, this study analyses data from a national survey of
marine users (i.e. fishers, divers, beach users etc.) about public participation in marine
research. The research is distinct in its approach to this issue, through its focus on potential
volunteers for marine citizen science rather than only volunteers who have already been
recruited in citizen science projects. The specific aim of the paper is to understand the
possibility for marine citizen science to attract volunteers who differ in their pre-existing
levels of engagement in science, since this has implications for the ability of citizen science
to affect broader societal shifts in the science/society relationship.
Public engagement in science versus public participation in science
Within the science communication literature, the terms public engagement and public
participation are sometimes used interchangeably. In the context of this paper however,
engagement and participation of the public in science are seen as having different meanings
due to differences in the directions of scientific knowledge flow (Figure 1). In essence, these
two concepts are similar to two of the three typologies of public engagement (i.e. public
communication and public participation) proposed by Rowe and Frewer (2005). Public
participation, as it is considered in this paper, extends the Rowe and Frewer (2005) model by
including public participation in scientific research (PPSR; Shirk et al., 2012). In the PPSR
model, the public are seen to be participating in the creation of scientific knowledge.
In contrast, public engagement in science (PES) sees the public as consumers of science
communication. Their level of engagement in science can be demonstrated by whether or not
they are interested in and pay attention to science communication (no matter the
communication method or reason for their interest; British Department for Business
Innovation & Skills [BIS], 2011; Department of Business and Innovation [DBI], 2012; Pew
Research Center, 2015; Reyes, 2013; Searle, 2014), how they interpret and understand the
information (Kahan et al., 2012; Lewandowsky & Oberauer, 2016; Stevenson, Peterson,
Bondell, Moore, & Carrier, 2014), to what extent they seek it out to use it for decision-
making (Scheufele, 2013), and so on.
Figure 1. Public engagement vs. public participation
Public participation in citizen science
PPSR encompasses the practice of citizen science, which can be described as “research
collaboration that involves volunteers in producing authentic scientific research” (Wiggins &
Crowston, 2015). Aside from conducting research, some citizen science projects also aim to
educate the public in science (Brossard, Lewenstein, & Bonney, 2005; Land-Zandstra,
Devilee, Snik, Buurmeijer, & van den Broek, 2016; Mayer, 2010) and expect these
experiential research activities to result in positive societal changes in the relationship
between science and society (Bonney, Phillips, Ballard, & Enck, 2015; Dickinson et al.,
2012; Haywood & Besley, 2014; Jordan, Gray, Howe, Brooks, & Ehrenfeld, 2011; Pecl,
Gillies, Sbrocchi, & Roetman, 2015).
There is often an implicit assumption that “non-scientist” volunteers come to citizen science
projects with relatively low levels of scientific knowledge or understanding, or (sometimes)
little support or interest in science. Yet studies of citizen scientists’ motivations indicate
many volunteers participate primarily to make contributions to science, which implies they
are at least somewhat “pro-science” (Curtis, 2015; Haywood, 2015; Johnson et al., 2014;
Raddick et al., 2013). In addition, volunteers in some citizen science projects have higher
levels of education than the general population (Brossard et al., 2005; Raddick et al., 2013).
Unfortunately the educational background of citizen science participants is rarely found in
published citizen science studies, so it is difficult to know whether this trend extends across
the field. Nevertheless, the indications in the literature bring into question the ability for
citizen science to affect broad societal change if it primarily recruits volunteers who are at the
higher end of the science engagement spectrum.
Justification for the study
This research examines potential volunteers from all levels of the science engagement
spectrum (although the higher groups are more readily represented in this study due to the
bias in the survey, discussed below). The difficulty in using broad definitions to describe
terms such “science” and the “public” (Burns & Medvecky, 2016) is acknowledged,
particularly as “science” can mean many different things in many different contexts, and the
term “public” does nothing to help a communicator understand the needs and interests of a
particular target audience. Yet, science communicators and public engagement strategies
remain tasked with not only defining target groups, but also with providing evidence to show
they have been successful. This necessitates a certain amount of quantitative research and
categorization to support evidence-based approaches to effective public engagement.
In addition, enthusiasm and support for citizen science is growing, often driven by
assumptions that public participation in it will be a “good thing” for the relationship between
science and society. For example, in November 2016 the Australian government announced it
will provide $4 million dollars in grants to support the growth of citizen science in Australia
(www.business.gov.au/assistance/inspiring-australia-science-engagement/citizen-science-
grants). These grants are available for projects that aim to “provide opportunities for the
public to engage in science” and form part of the national innovation initiative to “inspire
STEM literacy and engagement in all Australians”
(www.science.gov.au/community/Pages/Citizen-Science-Grants-announced). Australia’s
Office of the Chief Scientist also views citizen science in a favorable light, stating that it will
enhance Australians’ awareness of science (Pecl et al., 2015). Citizen science is also seen by
government organizations as having great potential to engage wide audiences in other parts of
the world such as Europe (Museum für Naturkunde, 2016) and the USA (Holdren, 2015).
While there does appear to be room for growing the number of citizen science volunteers, at
least in a marine context (Martin, Christidis, & Pecl, 2016), it is somewhat surprising that
considerable resources and effort are being provided for the further development of citizen
science without empirical evidence showing that it is likely to impact the types of people
these strategies aspire to reach. This study is a first step in the provision of such evidence,
which is necessary for assessment of the broader societal impacts arising from citizen
science.
Methodology
Given the focus of the Australian science engagement strategy, Inspiring Australia
(Department of Innovation, Industry, Science and Research [DIISR], 2010), this study took a
national approach to the research, using an online survey to gain responses across the
country. The development, testing and promotion of the survey has been reported elsewhere
(Martin, Christidis, & Pecl, 2016) however, for the purposes of this paper a summary of the
methods are provided here. The study focused on Australian marine users (that is, people who
use the beaches and oceans) since the Inspiring Australia strategy suggests marine science
offers opportunities to increase Australians’ engagement in science more broadly. Marine
science is emphasized in the strategy due to the strong connections and proximity most
Australians have with the marine environment (Department of Industry, Innovation, Science,
Research and Tertiary Education [DIISRTE], 2012).
National survey development
Several sources were used to inform the development of the survey questions employed in
this study. Background information was gathered on the marine users’ demographics, science
education, and interests in the marine environment to ensure a broad range of participants
were represented. Demographic questions were taken from the 2011 census of the Australian
population (sourced from www.abs.gov.au). Questions about people’s science education and
employment in the science industry were taken from the Victorian survey (Department of
Business and Innovation [DBI], 2012).
Questions used to measure levels of individual’s engagement in science (EiS) were modified
versions of the three survey questions used in the DBI (2012) and Cormick (2014) analyses.
These questions related to: (i) the individual’s interest in science, (ii) active searching for
science information, and (iii) ability to find and understand the information. In addition to
these questions, another was added to ask respondents about their trust in science due to the
considerable attention this issue receives in both academic (Achterberg, de Koster, & van der
Waal, 2015; Engdahl & Lidskog, 2014; Gauchat, 2011; Resnik, 2011; Wynne, 2006) and
mainstream publications (Lynas, 2015; Rutherford, 2015). The final questions (and
corresponding labels) used to develop the EiS score were:
(i) How interested are you in science, generally? (interest)
(ii) In general, how often do you actively seek out scientific information? (seek)
(iii) In general, how much do you trust scientific research? (trust)
(iv) In general, how easy do you find it to understand scientific information? (understand)
All responses were recorded on a 7-point scale (Table 1).
To determine the respondents’ willingness to participate in marine citizen science, another
group of questions (referred to as the PPSR questions in the analysis) were developed using
the term marine research instead of marine citizen science, since the latter is an unfamiliar
term for many Australians. The PPSR questions were grouped into two themes: (i) general
willingness to participate, and (ii) interest in specific research roles. Theme 1 questions were
designed to gain a measure of general interest in assisting marine research. Some of these
questions used 7-point scales to ask respondents about their level of interest in, and expected
enjoyment from participating in marine research. In addition, respondents were asked how
many hours per annum they are willing to volunteer for marine research. Theme 2 questions
presented respondents with a list of roles volunteers might perform in marine scientific
research, and asked them to record (on a 7-point scale) how likely they would volunteer for
each role. The list was based on the framework for PPSR developed by Shirk et al. (2012),
which describes the different ways in which volunteers participate in any, or all, aspects of
scientific research.
The questions used in the national survey were first tested during 110 face-to-face interviews
with marine users in four regions of Australia (Martin, Christidis, Lloyd, & Pecl, 2016). Once
the questions were refined and entered into the online survey platform (Qualtrics), they were
further tested by 12 people on a variety of devices in different locations across the country.
Minor wording changes were made for clarity. The survey was open for 8 weeks during
February – April 2015. It was promoted around the country using multiple snowball sampling
strategies (Bryman, 2012) in mainstream media (newspapers, radio, magazines), online and
social media (forums, Facebook, Twitter), and direct email campaigns using networks of
groups interested in the marine environment (clubs, special interest groups, etc.) as well as
groups with interests in marine research and citizen science (e.g. the Australian Citizen
Science Association, universities, etc.)
During the earlier face-to-face interview phase of the research, interviewees (which included
recreational fishers, divers, boaters, sailors, surfers, kayakers, life savers and beach walkers)
were asked whether they would be likely to complete a 30 minute online survey on the same
research topic. Many interviewees mentioned incentives would be necessary for such a
lengthy survey, and this was most noticeably the case for the interviewees with lower levels
of interest in science. Most of the interviewees suggested specific incentives related to their
preferred activity, such as a fishing rod. Lottery incentives, such as prize drawings, are not
uncommon in marketing-type surveys in Australia, and given the interviewees were very
particular about the types of prizes that would appeal to them, sponsors were sought to donate
relevant marine-related prizes.
In total, 20 prizes (together worth $2000) were offered, all of which were selected to appeal
to different target groups for the research. The prizes included a quality fishing rod and reel,
SCUBA diving vouchers, snorkeling equipment, an underwater scooter, marine life books
and DVDs, and marine communication equipment (an entertainment system for boats,
personal locator beacon, and mobile phone protectors). While the use of incentives is
controversial topic in social research, they have been found to increase participation in online
surveys (David & Ware, 2014, Edwards et al., 2009). Meta analyses have uncovered
variability in the effect of different types of incentives (e.g. cash incentives appear to be the
most effective, although Khadjesari, Z., et al. (2011) suggest the amount of cash paid to
respondents may influence the response rate). The approach taken in this study was driven by
the earlier discussions with the target audience, and was deliberate in its intention to appeal to
the harder-to-reach groups who were less likely to respond to such a survey.
The survey was commenced by 1375 people, of which 1145 were fully completed (83.3%
completion rate). Respondents represented a broad range of ages and interests in the marine
environment, and came from all states and mainland territories of Australia. Although it was
not intended to be representative of the Australian population, the most notable difference
between respondents and the 2011 population census data (sourced from www.abs.gov.au)
was the much higher proportion of postgraduate education for the survey respondents
(22.4%) compared to the census (5.2%). Half of the respondents (50.1%) had studied science
at the tertiary level, yet only around half of these people (equating to 26.7% of respondents)
were working in the science industry.
Analysis
After data screening and cleaning, the analysis proceeded in two main stages: (i) the
computation of the EiS scores and EiS groups, and (ii) the EiS groups were checked for
significant correlations with the PPSR measures and significant between-groups differences
in the mean PPSR scores. Prior to the formation of the EiS groups, the four EiS measures
(interest, seek, trust and understand) were checked for scale reliability using Cronbach’s
alpha (Field, 2013), which indicated the scale was acceptable (α = .823, which increases
to .855 if trust is removed). There were no issues of multicollinearity between the variables
(all correlations < .90, Field, 2013), there was no missing data, and all scales used were of
equal size (7-points). All scale items were found to be non-normal using both the Shapiro-
Wilk and Kolmogorov-Smirnov tests for normality, meaning non-parametric analyses were
necessary (Field, 2013). An exploratory factor analysis was conducted on the scale items
using principle axis factor extraction (Osborne & Costello, 2009). The analysis returned one
factor that included all of the variables, however it showed trust had a much lower factor
loading (.479) compared to interest (.862), seek (.856) and understand (.740). The
combination of the four items explained 56.33% of the variance, however when trust was
excluded this increased to 67.95% of the variance. For this reason, trust was removed from
the analysis. The Kaiser-Meyer-Olkin measure verified the sampling adequacy (KMO = .705,
which is well above the acceptable limit of .5; Field, 2013).
Before determining EiS group membership, the data was split into two groups: working
scientists (which includes all respondents working in the science industry, of which 91.5%
studied science in higher education and the remainder are likely to be administrative or
technical staff in scientific organizations) and non-scientists. This was done for two reasons:
(i) working scientists or staff in scientific organizations are more likely to become involved in
research through their own work interests, either voluntarily or through their employment
(however it was noted this group responded across the full scale of the EiS questions, with
the majority at the more favorable end of the scale), and (ii) citizen science practice often
claims to engage “non-scientists”, so it is important to conduct the analysis on the potential to
engage this group specifically.
The EiS scores for non-scientists were calculated by summing the responses to the three EiS
questions, each of which used a 7-point scale (resulting in a possible score range of 3-21)
which were then used to group respondents. The group EiS score cutoff points were based on
the range of scores corresponding to relevant levels on the measurement scale, taking into
account the negative skew in the responses (all EiS questions and scales are presented in
Table ). The final EiS groups were assigned descriptors defined as: low (scores ranging from
3-11, i.e. all fell below the midpoint of the scale; N = 67, M = 9.22, SD = 2.01), ambivalent
(scores ranging 12-14, i.e. around the midpoint of the scale; N = 164, M = 13.17, SD = .79),
moderate (scores between 15-17; N = 275, M = 16.03, SD = .78), high (scores between 18-20;
N = 267, M = 19.04, SD = .81), very high (score of 21, i.e all respondents who selected 7 on
every scale; N = 56, M = 21.00, SD = .00), and working scientists (N = 316, M = 19.22, SD =
2.06).
The six EiS groups were then assessed for differences in demographics and their responses to
the PPSR questions. All statistical tests were carried out according to Field (2013).
Correlations using Spearman’s rho and bootstrapping were calculated between EiS scores and
PPSR variables. Differences in means were tested using the Kruskal-Wallis test and post-hoc
analysis was performed using the pairwise comparison procedure. Effect size for each
pairwise comparison was calculated using eta squared. SPSS 22 was used to run all analyses.
Results
The five non-scientist EiS groups describe broad audience types by their EiS measurements,
ranging from low to very high engagement in science (Table 2). In general terms, the higher
the EiS group membership, the higher the level of education generally, and science education
specifically. All groups have more males than females. The low and ambivalent groups have
a greater proportion of respondents older than 45 years compared to the higher-level EiS
groups.
EiS group differences in PPSR questions
General interest in citizen science participation
The majority of respondents to this survey are willing to assisting scientific research in some
way (this could be anything from medical research to filling in surveys), however while most
of the higher EiS groups are “definitely interested” there is a relatively high percentage of
respondents in the low (71.6%) and ambivalent (50.0%) EiS groups who answered “maybe”
to this question (). The number of hours respondents are willing to volunteer for marine
research represents considerable volunteer effort, however the higher EiS groups are willing
to donate more hours per annum overall than lower EiS groups.
The responses to the questions about level of interest, enjoyment and confidence in their own
ability to assist marine research show a low positive correlation with EiS group membership.
Responses to these questions were significantly different between the groups (see H and p
values in Table 3), and pairwise comparisons of group means for these questions showed
statistically significant differences in the responses of the high, very high and working
scientists compared to the lower EiS groups (see notes for Table 3). Working scientists and
the very high EiS group also stood out as having the strongest confidence in their ability to
assist marine research. Large effect sizes occurred between low – high, and low – very high
EiS groups for these three questions, as well as between ambivalent – very high for the
enjoyment and confidence questions. The majority of effect sizes for the remaining groups
were medium to low1.

Interest in specific roles in PPSR
The likelihood of respondents participating in the different roles in PPSR (measured on a 7-
point scale where 1 = very unlikely and 7 = very likely) shows a low positive correlation with
EiS group membership (Table ). Group means for each of the PPSR questions were
significantly different (see H and p values in Table 4), and increase with EiS group
membership up to the very high group, after which it drops slightly (but not significantly) for
the working scientists group. Mean scores below 4 on the scale indicate groups are unlikely to
participate in particular roles. This is the case for all roles except data collection in the low
EiS group. The ambivalent and moderate group means hover around the midpoint (between
3-5) for most roles, except data collection which increases above 5. Data collection is also the
most preferred role for all remaining groups. Data analysis and communication of the
findings are either the second or third most preferred roles for the high, very high, and
working scientist groups (all receiving scores above 5.26). The very high group is the only
group to score above 5 for all PPSR roles.
Statistically significant differences occur between groups for all PPSR roles. There is a clear
difference between the lower (low – moderate) EiS groups and the higher (high – working
scientists) groups for all roles except two, and group differences also occur between the lower
and higher groups. The two exceptions to this result are data collection and data analysis
roles, both of which differ significantly between the lower two groups (low – ambivalent) and
the remaining (moderate – working scientists) groups (in other words, the top four groups
rated their likelihood of participation significantly higher than the bottom two groups).
In summary, the six EiS groups vary significantly in their engagement in science, and
potential engagement in PPSR activities. The tests for group differences in their interest and
likelihood of participation in marine research show PPSR opportunities appeal most to people
with pre-existing high levels of EiS, and it is unlikely (although not impossible) to attract
volunteers whose EiS score is low.
Discussion
This study segmented marine users into six audience types based on their current level of
engagement in science. It detected discernible differences in their general interest in
volunteering for marine research as well as their likelihood of participation in a range of
marine research roles which are proposed within the PPSR framework. This information is
useful for an evidence-based approach to strategies employing citizen science for the purpose
of increasing public engagement in science. It is especially important to bear in mind when
assumptions are made about the ability and usefulness of citizen science in bringing about
societal impacts in the low or ambivalent EiS groups.
Limitations
While this research attempted to gain broad perspectives on Australian marine users’ level of
interest in citizen science, there are three important limitations to this study. First, its focus on
the marine environment means the findings are very context-specific. This raises the question
about the applicability of the results to terrestrial, freshwater, and virtual environments,
where a great deal of citizen science activity also occurs. However, the indications so far
suggest that mainstream citizen science across many different fields lacks socio-economic
and educational diversity amongst volunteers (Hobbs & White, 2012; Pandya, 2012; Raddick
et al., 2013; Soleri, Long, Ramirez-Andreotta, Eitemiller, & Pandya, 2016). The results
presented here support this important finding, which is particularly concerning for the
expectations of some for societal impacts arising from citizen science.
The second important limitation to this research arises from the use of a lottery incentive to
recruit respondents. While this approach was informed by consultation with the target
audience prior to the release of the survey, it may have resulted in attracting only respondents
who are motivated by material incentives rather than altruistic reasons. The study aimed to
gain responses nation-wide from marine users with diverse interests in science, especially
people in the lower EiS groups who are a notoriously difficult group to study (Cormick,
2013; Evans & Plows, 2007; Powell, Colin, Lee Kleinman, Delborne, & Anderson, 2010;
Stevenson, Sikich, & Gold, 2012). Although these groups are likely to be underrepresented in
this research, there is enough variation in the results to at least shed some light on
engagement with this group, and the use of incentives helped to achieve these responses.
The third limitation relates to the natural bias arising from snowball sampling, which results
in groups with similar interests (in this case, an interest in participating in marine research)
responding to the survey. Despite effort to craft survey recruitment messages to convey that
the study aimed to survey people who are, and people who are not willing to assist marine
research, it is not surprising to receive a greater proportion of those who are. This may
account for the overrepresentation of respondents with postgraduate degrees and higher
education in science. Separating the working scientists in the analysis helped to remove the
impact of this limitation.
Who is most likely to volunteer in citizen science?
The EiS groups differ in many of their background factors, particularly their level of higher
education and education in science. The very high EiS group is the most interested in
assisting scientific research, and the most likely to participate in PPSR activities. This group
is also the most highly educated. This finding parallels other social research in citizen science
and environmental volunteers, which has revealed volunteers tend to have educational
qualifications which are higher than average (Brossard et al., 2005; Dresner, Handelman,
Braun, & Rollwagen-Bollens, 2015; Evans et al., 2005; Raddick et al., 2013). This study also
shows people who are most likely to volunteer for marine research may also have higher
education and training in science, yet are not necessarily working as scientists. This may
partially explain why those who participate in citizen science do not necessarily change their
(already positive) attitude towards science following the experience (Brossard et al., 2005).
The results also highlight the valuable knowledge and skills enthusiastic volunteers may
bring to citizen science; a detail which should not be disregarded or undervalued. The keenest
volunteers are not necessarily, as some suggest, simply “lay people”, “non-scientists”, or
even “non-professional scientists” (Evans & Plows, 2007; Foster-Smith & Evans, 2003;
Haklay, 2013; Lewenstein, 2004). The assumption a “citizen scientist” has little
understanding of scientific processes may be incorrect in some circumstances, and may
contribute to the perception of some professional scientists that citizen science data is not
reliable or robust (Cohn, 2008; Fore, Paulsen, & O' Laughlin, 2001; Gollan, 2013; Newman,
Buesching, & Macdonald, 2003). Definitions of “citizen scientists” need to acknowledge
some volunteers may be professional scientists (or at least tertiary trained in science), who
are willing to perform unpaid roles in research projects.
The ability of marine citizen science to recruit many more volunteers who are already pro-
science is a positive outcome for the future of citizen science (since highly skilled volunteers
can be very useful). This scenario will help to address the urgent need to broaden the spatial
and temporal scale of marine research and improve our understanding of the rapid changes
occurring in the world’s oceans (Healey, 2016; Koslow & Couture, 2015; Marzloff et al.,
2016; McCauley et al., 2015). However, the results of this study bring into question the
realistic ability for marine citizen science to engage Australians who are less than enthusiastic
about science.
Engagement of other EiS groups
While the very high EiS group is the “low hanging fruit” for marine citizen science
recruitment, there is strong potential to engage the moderate and high groups, bearing in
mind they feel less able to understand science, and are less confident in their ability to assist
marine research than the very high and working scientists groups. In another analysis of data
from this survey, which used a case study of a project that asked for photographic records of
marine species distributions, the only significant barrier was people’s perceived lack of
knowledge about marine species (Martin, Smith, et al., 2016). Since all groups were most
interested in helping to collect data, projects which combine data collection and opportunities
to increase volunteers’ knowledge of marine species may be important gateways for
recruitment of the moderate and high EiS groups.
Helping potential volunteers overcome their perceived knowledge deficit will require
education and training. For some projects, volunteers need very little knowledge, in which
case it will be important this is communicated in recruitment messages. For other projects,
volunteer education might take several different forms, and should be determined through
research with the target groups. Examples include species identification guides (or similar
guides appropriate to the field of study), direct feedback from scientific experts on the topic,
workshops (online or in person), videos, and support groups on social media. Given many
potential volunteers are eager to learn more (Martin, Smith, et al., 2016), these types of
educational opportunities may be reward enough to engage people with mid-range EiS
scores.
Only one PPSR role (data collection) received a positive mean score for the low EiS group,
yet this was barely over the scale midpoint. Despite this, the results show there are some
members of the low and ambivalent EiS groups who are willing to participate and donate a
great number of hours to assisting marine research. Compared to the higher EiS groups, these
lower two groups have a greater proportion of people who answered “maybe” to the question
about their willingness to help any type of scientific research. This hints at certain personal
caveats for volunteering. Matching the interests of these groups with the objectives of citizen
science project, and the roles volunteers can play, will be essential for engagement of these
groups. In addition, analysis of other data from this survey showed marine user groups (e.g.
recreational fishers or divers) are more willing to share data with some organizations than
others (Martin, Christidis, & Pecl, 2016). Relationships and trust are also essential for
engagement, which can be impacted by the worldview of the lead organization (Wynveen &
Sutton, 2015). Examples around the globe of community-driven, co-created (Shirk et al.,
2012) citizen science, such as the GardenRoots project (Ramirez-Andreotta, Brusseau,
Artiola, Maier, & Gandolfi, 2015), show that it is possible to engage a broad range of people
who are often brought together by a shared concern. These are the sorts of issues that need to
be considered in citizen science project design and communication for recruiting the lower
EiS groups.
The low EiS group reported much lower education levels than others, making them a key
group science communication strategies aspire to target (Cormick, 2012). Engaging these
audiences in citizen science may prove to be an impossible barrier for many scientist-led
projects. The situation is made more difficult by the majority of citizen science projects
asking the volunteers to come to them (rather than taking the science to the audience and
engaging on their terms) and demonstrates a lack of understanding about the disconnection
some groups have with the “elite” world of science (Callon, 1999).
Conclusion
Increasing the public’s understanding and support for science is not the main priority for
many citizen science projects (Bonney et al., 2015; Wiggins & Crowston, 2011), and nor
should it be for all projects, yet it is an often-stated aim in citizen science practice and is
promoted as such by governments keen to see greater public engagement in science
(Department of Industry, Innovation and Science [DIIS], 2016; Museum für Naturkunde,
2016; Pecl et al., 2015). The results presented here suggest mainstream scientist-led projects,
which form the majority of citizen science practice (Kullenberg & Kasperowski, 2016), may
appeal more to a narrower type of audience, that is, one which is already paying attention to,
and is supportive of science.
What does this mean for citizen science? In the big picture, these findings are important
considerations for the future direction of citizen science, which is guided by statements and
support from citizen science associations, governments, funding agencies, research
institutions, NGOs and the like. The actors at this level will need to think about how they can
support a greater diversity of participants in citizen science if broader science engagement is
the goal. At the individual project level, the aims of each will differ and improving public
science engagement may not be the priority for some. For those that aspire to achieve this,
these results demonstrate the need to understand who their target audience is and how best to
recruit and retain them.
For citizen science to reach its full potential in facilitating broader societal impact in public
science engagement, there are considerable institutional, practical, and societal barriers that
need to be removed. Challenges exist for all stakeholders in citizen science. Addressing these
barriers will require a rethinking of the way citizen science is designed, implemented,
supported, promoted, reported, and importantly, the way it incorporates the wider community
in its practice.
