Research:Science Controversies in Portuguese Wikipedia: The Case of Global Warming
There is a strong consensus among scientists studying climate change: 97% of them say the global surface temperature is warming due primarily to greenhouse gases emitted by several human activities. Nevertheless, climate change is the subject of an intense public controversy – some contrarian voices dispute several aspects of the mainstream claims.
The aim of this study is to investigate how such a peculiar controversy is performed in Wikipedia, a free collaborative encyclopedia that, unlike other reference works, does not require expertise of its editors. Do global warming related articles reflect the scientific consensus? Is there any space left for the claims of the contrarians? These are some of the questions this study intends to answer. In order to do that, we will carry both a quantitative and a qualitative study of a sample of global warming related articles in Portuguese Wikipedia.
I intend to approach my research problem with the conceptual tools provided by Actor-Network Theory, which have been shown suitable for addressing both the resolution of science controversies and the sociotechnical environment of Wikipedia.
I'm Bernardo Esteves and this research is part of my doctoral thesis in History of Sciences and and Techniques and Epistemology at Federal University of Rio de Janeiro, Brazil, under the supervision of Henrique Cukierman.
Aligned with Actor-Network Theory, in this study I consider Wikipedia as a sociotechnical system composed of a network of human and non-human actants negotiating the evolution of the articles and the management of the encyclopedia. I draw on previous research investigating Wikipedia under similar light. I also draw on the available literature considering climate change related articles in Wikipedia and, more specifically, the case of William M. Connolley. Last but not least, I draw on studies investigating controversy and conflict resolution among wikipedians.
Most studies referenced above focus on English Wikipedia only. But patterns of usage of the system may vary significantly between different communities of users. Portuguese Wikipedia editors have been shown, for instance, to have different patterns of interaction comparing to other languages’ wikipedians. Therefore, the conclusions of the cited literature may not always apply to PT-Wikipedia and I should be cautious while considering them in this study.
There is a modest but growing body of research devoted to PT-Wikipedia. Even though few studies relate directly to what I intend to investigate in this study, I draw also on this specific literature in order to understand patterns of edition of PT-Wikipedia users. As far as I know, the articles reporting preliminary results of this research were the first to address climate change in PT-Wikipedia.
In order to address my research problem, I intend to carry a quantitative and qualitative study of a sample of climate change related articles in PT-Wikipedia.
The quantitative study will investigate a number of parameters in the revision history of a sample of articles considered until December 31, 2013. The sample includes all articles labelled under the Template:Global warming and those included in the Category:Climate change (and its subcategories). The sample consists of 93 articles as of February 14, 2014. I intend to investigate the following parameters and to look for correlations between them:
- Number of days of existence
- Size (bytes)
- Average number of modified bytes per edit / Total number of bytes in the article
- Number of references
- Total number of edits
- Number of edits per month
- Number of edits per IP / registered users / bots
- Number of editors
- Number of edits per user
- Number of edits in the talk page
- Number of edits in the talk page per number of edits in the main article
- Number of watchers
- Number of reverts
- Number of days under protection (%)
- Number of days under a template that might signal controversy or neutrality issues (%)
- Page views in 2013
I intend to compare the results with the average values for all PT-Wikipedia articles. I also intend to compare them with a smaller sample of articles addressing other science related controversies and with a smaller sample of articles deemed controversial by the community of users of PT-Wikipedia.
I also intend to compare the patterns of edition of climate change related articles with other versions of Wikipedia (English, German, French and Spanish). For this comparison I will work with a smaller sample limited to the three most heavily edited climate change articles (“Global warming”, “Greenhouse effect” and “Kyoto Protocol”).
In the qualitative study, I will monitor the whole revision history of the three most heavily edited climate change articles and their talk pages. I will look for interventions that might help understand how the users negotiate conflicting points of view concerning the attribution of climage change.
I will try to interview the most active contributors to those articles and their talk pages. Users will be contacted through their talk pages. Those willing to participate will be sent a questionnaire focusing on aspects such as the source of the information they are contributing to climate change articles, their perception of the climate change controversy and their perception of the way it is being portrayed by PT-Wikipedia. Interviews will adhere to the ethical guidelines recommended to Wikipedia researchers.
