This spring, the Methods Lab student assistant, Diana Ignatovich, spent four months at Dartmouth college to research octopus cognition and visual processing.
Hidden in the New England wilderness is an underground laboratory housing three male Octopus bimaculoides that were shipped from the Pacific Ocean for non-invasive study using underwater electroencephalography (EEG). One of the octopuses was named Joseph—after the Weizenbaum Institute’s namesake, computer scientist Joseph Weizenbaum.
Octopus Joseph on the first day in the lab.
Rather than euthanizing the octopus or holding its tentacles down to understand its incredibly complex and decentralized nervous system, the underwater EEG apparatus used here is methodologically unique, to ensure no octopuses were harmed. This method records the brain’s electrical activity by detecting signals from groups of neurons, which are amplified by the EEG machine and studied as brain waves. To record this data, the experimental tank consisted of a clear plastic cube with two printed circuit boards on top and bottom, lined with tripolar concentric ring electrodes and submerged in saltwater. The tanks were also enriched with toys to encourage cognitive stimulation, and all experimental procedures were conducted in accordance with ethical guidelines approved by the Institutional Animal Care and Use Committee (IACUC).

The primary project for this stay was in assessing the neural critical flicker fusion frequency (CFF) of the octopus via steady-state visual evoked potentials of the EEG power spectrum. The CFF threshold refers to the point at which a rapidly flickering light is perceived as steady, which indicates the speed of visual information processing in the brain. This gives insight for neural and visual processing efficiency as well as cognitive functions such as attentional control and overall responsiveness to changing environments. It is also commonly measured in psychophysics via behavioral paradigms, where a participant indicates the observed flicker fusion. However, since Joseph could not tell us about this boundary, the threshold was marked by a drop in EEG signal amplitude as flicker perception diminished. These experiments, performed using LED light at different brightness levels, were then repeated with human testing for comparison, to determine whether octopuses are better adapted to low-light conditions due to their underwater habitat.
The octopuses demonstrated higher critical flicker fusion frequency thresholds compared to humans, likely due to their evolutionary history and environmental conditions, where quick visual responses are necessary to spot prey or avoid predators.
Diana and Joseph before experimentation
It’s extraordinary that octopuses, despite lacking the rod and cone photoreceptor cells found in most eyes, have adapted to match or even exceed the critical flicker fusion thresholds of creatures like humans. These results are an exciting glimpse into the diversity and complexity of how other species experience their own vastly different worlds in nature.

As digital methods advance rapidly, quantitative empirical research requires greater computing power. This includes complex statistical analyses, model training, and operating generative AI models. The necessary hardware is expensive and challenging to maintain, particularly at the institutional level (e.g., due to high temperatures in HPC clusters). Since not every institution can (or should) set up such hardware independently, resources are shared through collaborations with other institutions.
Against this background, the Weizenbaum Institute is exploring options to enable both low-demand computing tasks (e.g., a virtual machine for background web scraping) and high-demand tasks (e.g., running current large language models) for its researchers. Recently, the following options have been identified (some of which are only available to Berlin scientists):
Community-driven web-based analysis platform for life science research
Free to use batch system with many tools usable by browser, huge data sizes are no problem
Although coming from Bioinformatics, there are many tools for text processing, audio and image analyses, as well as statistics can be put together in pipelines.
Support from the state of Berlin, linked to BUA, e.g. BI-FOLD also calculates there
Provides tailor-made solutions, e.g. can make own instances of HAWKI, LibreChat or similar available with WI licenses
Resources available only by collaboration.
Apart from these external offers, the Weizenbaum Institute itself already provides some services to its researchers:
Virtual machines
Jupyterhub
Gitlab
Researchers who are interested in using any of these services can follow the instructions on the according websites for external services. For internal services, instructions are provided in the internal WI Wiki.

Every year, the International Communication Association (ICA) organizes a conference where communication scholars from around the globe present and discuss their current research. In June 2025, the conference took place in Denver, USA, and many Weizenbaum Institute researchers contributed to it. Among others, Methods Lab member Roland Toth, together with colleague Jakob Ohme, former fellow Joseph Bayer (Ohio State University), and his team members Razieh Pourafshari and Yifei Lu, organized a conference panel called “Miss the Mobile Methods Turn? Reflecting on the Challenges and Potentials of Mobile Communication Science”.
Roland Toth outlines the issue with mobile methods
Many social scientists use mobile data collection methods, such as the Ecological Momentary Assessment, data donations, or event log data, but there are hardly any standards or guidelines to work with. The panel addressed this lack of standardization and accessibility of mobile methods within and outside of communication science. In the introduction to the panel, the issue was outlined and attendees were asked to complete a short survey about their expertise regarding different mobile methods, problems they recognized, and whether and to what extent they are willing to contribute to future initiatives to improve the situation.
Gabriella Harari presents issues with capturing the context of smartphone use
After the introduction, experienced mobile communication scholars presented examples of empirical research that highlight current practices, challenges, and future perspectives associated with mobile methods. Following these short talks, the presenters, attendees, and organizers discussed possible standards, priorities, and endeavors to strengthen this growing research area, as well as how the community can organize to support the use of mobile methods to the Communication field at-large.
Jakob Ohme moderates the general discussion with the presenters, attendees, and organizers
The panel was received well and paved the way for further steps to gradually tackle these issues. The discussion shed light on the wide interdisciplinary use of mobile methods and their relevance, both in and beyond communication science, that goes along with that. It showed that there currently is potential for all panel presenters, attendees, and organizers, but also other communication researchers, to contribute to the advancement of mobile methods across fields, which the Weizenbaum Institute aims to participate in. Accordingly, based on the results of the survey, future initiatives such as white papers, methods reviews, or workshops addressing the current state and standardization of mobile methods will be planned. Stay tuned for these in the future!
Whether it’s unwinding after a long day or killing time in line for coffee, social media has become a major source of entertainment and connection. The immediate satisfaction it often brings can boost the mood, but it’s not just entertainment we’re absorbing. Amidst the lighthearted content, is exposure to a wide range of information, much of which we may not fully process. Research suggests a link between high social media usage and lower self-control, which may also perpetuate processes of dissociation that many refer to as mindless scrolling. As we passively absorb media from smiling koalas to political protesting, how are we actually understanding the more consequential information and even shaping our opinions?
Lion Wedel and Jakob Ohme consider these influences in collaboration with Bayerischer Rundfunk, Stuttgarter Zeitung, and the University of Zürich in their project, Dein feed, deine Wahl, (Your Feed, Your Choice/Election). In this ongoing initiative, TikTok users are encouraged to donate their data in an anonymous manner and in turn receive a direct analysis of the political content and parties appearing in their feed.
The findings depict the daily number of TikTok videos posted by political parties
Jakob and Lion shared their perspectives in an interview, offering insight backed by their expertise in political communication and digital media research.
To begin, Lion and Jakob discuss the broader implications of media on shaping one’s ideological framework. Specifically, which types of content shape opinions the most, and how do they attract attention?
To this, Lion responds,
“The more time you spend preparing a video, the less popular it gets. Like quick and dirty typically works better.”
This was in reference to a podcast titled, Was tun? Die Strategien hinter dem Comeback der Linkspartei (1/3): Wie Heidi Reichinnek die AfD auf TikTok überholte, in which Felix Schulz, social media manager in Heidi Reichinnek’s office, explores the strategic use of TikTok to engage young voters. From this, Lion highlights the influential processes through which opinions are likely to form online. He quotes the manager’s technique, asserting that his videos did so well because they managed to make a compelling statement in the first one to three seconds of the clip. Even in regard to political news, Lion describes, “It does not matter if it’s true or false, or if it’s catchy or misleading, you just have to get that attention grabbing moment.” He concludes by suggesting this content that keeps its audience engaged to the video’s end, is more likely to shape opinions.
But what are the implications to the broader democratic landscape in Germany if people form political opinions based on whatever content is most stimulating in their feed, regardless of its credibility? Can the use of traditional media repertoires play a role in fact-checking political discourse?
Statistics of the 2025 Weizenbaum panel report exploring last year’s political participation in Germany may suggest otherwise. Since 2021, there has been a decline in the use of traditional media sources such as newspapers and radio for news consumption, while internet usage has remained consistently stable. Moreover, over 60% of voters up to the age of 30 receive their political information from social networking (Schöffel et al., 2025), suggesting platforms such as TikTok are inevitably shaping how many engage in political debate.
Given recent civic tensions in Germany, including shifts in numerous elections and widespread protests, there appears to be a similar polarization in the spread of social media information. As many are more likely to express their opinions than change them, and online discussions often dominate in one direction of opinion (Xiong & Liu, 2014), raising awareness of these influences not only to our personal perspective but also the broader political environment becomes critical.
According to Jakob, the nature in which algorithmic selection processes function, “affect political landscapes to an extent that we probably ten years ago did not think was possible.” He outlines his interpretation of how algorithmic platforms contribute to political shifts, attributing the cause to the often passive behavior of individuals online, where their feeds reflect the content they prefer. As seen in previous research, social networking individuals may feel a reduced sense of self awareness and volition (Baughan et al., 2022), often consuming the content that is most interesting and aligns with their worldview. Jakob concurs, stating, “We can all function like this from time to time.”
He continues,
“There is content that works better with the algorithm and especially on TikTok. We can see that as soon as something works, it will capture a lot of attention, but as soon as something doesn’t work, it will completely drown. There are certain kinds of political content that work better and that is the emotional appeal, opinionated, negative and extreme information.”
Jakob asserts that certain political parties, especially those on the right-wing, are more adept at taking advantage of this dynamic, as their content tends to perform better online. Algorithms may as a result appear to favor them, not because of any inherent political bias, but because these parties successfully leverage a system that operates based on audience engagement patterns to maximize their impact.
Consequently, the Dein Feed, deine Wahl initiative establishes an objective foundation for identifying usage patterns within TikTok’s algorithms that ultimately contribute to the broader political climate. Jakob emphasizes the significance of these usage trajectories, aiming to explore their association with voting decisions and provide a descriptive overview of the extent to which individuals encounter political party-related content. In addition to this, he expresses the ambition to reverse-engineer algorithms to mitigate their effects. By examining how usage patterns influence algorithmic decisions and lead individuals to encounter more of the same content over time, researchers are better equipped to address these dynamics. This approach is especially essential given that analyzing video content and user interaction data has been largely unexplored due to its methodological complexity.
Overall, this project paves the way for regulating social media platforms in the long term, with the hope that it remains accessible for prospective political debates and elections. However, to move forward, Lion identifies the collection of data donations as one of the first priorities. The quality of the analysis significantly depends on the number of public contributions volunteered to their data donation lab.
Therefore, if you’d like to support the project or are curious of the political makeup in your own feed, please donate your usage here!
Machine learning is becoming increasingly central to academic research, yet it often depends on data workers in exploitative conditions whose contributions are largely overlooked in ethical guidelines and unacknowledged within the academic community.
This paper builds on the insights of an interdisciplinary group of scholars, practitioners, and data workers, alongside expert workshops held at the Weizenbaum Institute in 2024. It organizes practical principles for engaging more ethically with platform-based data workers, including how to define data work to then address important gaps in current ethical guidelines. The paper therefore offers concrete recommendations and regulations based on the most pressing challenges faced by these contributors. As the rapid development of AI continues to rely on the insight and labor of real people, it’s crucial to reflect on how research is conducted to ensure those workers receive proper acknowledgment for their role. This discussion paper calls for commitment to fair treatment, transparency, and meaningful support to make ethical data work a consistent part of the machine learning research process.

Back in October 2024, the Methods lab shared a preprint of a study by Methods Lab member and data scientist, Roland Toth, and former research fellow, Douglas Parry, exploring how to isolate meaningful measures of smartphone use from Android event log data. We’re now pleased to announce that this work has been peer-reviewed and published in the journal Computational Communication Research.
The article titled “Extracting Meaningful Measures of Smartphone Usage from Android Event Log Data: A Methodological Primer” outlines a practical and reproducible step-by-step guide for deriving objective indicators of human usage from raw mobile data, offering valuable insights for research in social science and related disciplines. It details the extraction of key usage metrics through written explanations, visual aids, and pseudo-code. The paper is a vital resource for researchers seeking to understand patterns of mobile phone engagement and its implications in today’s rapidly evolving digital environment.
