Research:Anonymity and conformity over the net
Key Personnel 
Project Summary 
The effects of anonymity on groups online vary between the circumstances that exist in social networking media today but lacks significant research on the differences between the anonymity states that could exist online. This paper tries to explore these differences between the anonymity states and the effects on group behavior, especially group-think. Understanding if people would behave in a different manner under different anonymity states could improve the decision making process for online groups. A direct implication of this is that it could also make the choice easier for software engineers that need to decide if and how they should provide anonymity to their users. This could improve the results from the decision making groups and their efficiency in general.
Exploratory study has been conducted in a convenience sample on Facebook but the results need to be confirmed with more rigorous sampling methods.
- The sample from the population will be obtained by randomly selecting from the Active User List page.
- Participants will receive an invitation on their personal talk page.
- The incentive that will be given to the participants is one of knowledge. Once the data are processed the results will be sent to them personally.
- Participants that didn't complete the survey may be notified a second time after 15 days to increase response rates.
- All participants that will request to opt-out of the survey will not receive a second notification
- In addition any participants that explicitly requested not to participate in surveys and exist in a list provided from the Research Committee of the Wikipedia will be excluded from the sample.

A preprint version is also archived at the author's website: Preprint with final corrections
Datasets can be found on the author's website as well: Quantitative and Qualitative datasets
Datasets will be shared. If it is before or after the analysis or publication is left to the Wikipedia Committee's decision to decide what is best. Results will also be published on relevant wikipedia page's for groupthink, conformity, anynomity etc.
Wikimedia Policies, Ethics, and Human Subjects Protection 
This study is part of Dissertation thesis proposal that has been approved by the Doctoral Committee of Masaryk University, Faculty of Informatics. There are no foreseeable dangers or ethical issues that may arise from this study.
Benefits for the Wikimedia community 
Understanding how people collaborate under different anonymity states and if there are any differences between those anonymity states is important for the development and improvement of the over collaborative community that Wikipedia is.
As an example, the final review process of this research and other proposals on wikimedia sites are governed by the rules of conformity and may be affected by the choices that people make with their profiles(nickname, real name or even anonymous). Understanding how anonymity affects the voting procedures is important for having a better collaborative community.
