The Effects of Surveillance and Copyright Law on Speech: Jon Penney at Berkman

What effects do laws and surveillance have on the exercise of freedoms online?

Today, the Berkman Center welcomed Jon Penney (@jon_penney), who is finishing his D.Phil at the University of Oxford, to talk about his dissertation research on chilling effects. Jon is a lawyer, Oxford researcher, and a research fellow at the the University of Toronto's Citizen Lab.

What is a chilling effect? The idea, theorized in a US context by Schauer in 1978, was that laws might have an effect on legal, protected, and desired activities. Judges have been skeptical about this idea. In Laird v Tatum, judges claimed that chilling effects were not a 'cognizable' injury. In response to recent NSA cases, chilling effects were dismissed as too speculative. Scholars agree. Kendrick argued that chilling effects have a "flimsy" empirical basis. Many open questions remain, including the magnitude of chilling effects and their reach. In his dissertation, Jon set out to answer some of those questions.

reddit Moderators: Let's Test Theories of Moderation Together

Are you a reddit moderator or the creator of software to support moderation (bots, browser plugins, etc)? Do you have questions about the effectiveness of your tools or your approach to moderation?

Over the next few months, I'm looking for moderators, tool-builders, and experienced community members to design moderation experiments together to answer questions or debates that your subreddits have about moderation. TLDRAre you involved in debates about the impact of subreddit moderation policies on your communities? Let's Talk! If you are interested, send me reddit mail at /u/natematias or participate in the /r/TheoryOfReddit conversation about this research.

Designing The Numbers That Govern Wikipedia: Aaron Halfaker on Machine Learning in Large-Scale Open Production

How can we engineer open production at scale, and what can we learn from feminist critiques of technology that could help us achieve those goals? At the Berkman Center this Tuesday (video), Aaron Halfaker talked about the challenges of scaling large-scale cooperation, the values that motivate efforts to keep that cooperation going, and lessons from Feminist Science and Technology Studies for maintaining large-scale socio-technical endeavors like Wikipedia.

Monitoring, Explaining, and Intervening: Field Experiments and Social Justice

What role can field experiments and other causal research play in efforts toward social justice in social computing? Aren't experiments tools for reductionistic, top-down paternalism? How could causal inference ever support grassroots approaches to social justice?

This question is a central struggle in my effort to decide a dissertation topic. The idea of participatory experimentation motivated me to work on the cornhole experiment. It was also at the back of my mind in my talk on discrimination and other social problems online at the Platform Cooperativism conference (start at 1:00:30 mark). In this post, I outline my current thinking on this question.  I would love to hear your thoughts in the comments.
