Biases and Stereotypes in LLMs

The paper “Revisiting the Trolley Problem for AI: Biases and Stereotypes in Large Language Models and their Impact on Ethical Decision-Making” by Sahan Hatemo, Christof Weickhardt, Luca Gisler (FHNW School of Computer Science), and Oliver Bendel (FHNW School of Business) was accepted at the AAAI 2025 Spring Symposium “Human-Compatible AI for Well-being: Harnessing Potential of GenAI for AI-Powered Science”. A year ago, Sahan Hatemo had already dedicated himself to the topic of “ETHICAL DECISION MAKING OF AI: An Investigation Using a Stereotyped Persona Approach in the Trolley Problem” in a so-called mini-challenge in the Data Science degree program. His supervisor, Oliver Bendel, had told the other scientists about the idea at the AAAI 2025 Spring Symposium “Impact of GenAI on Social and Individual Well-being” at Stanford University. This led to a lively discussion. The student recruited two colleagues, Christof Weickhardt and Luca Gisler, and worked on the topic in a much more complex form in a so-called Challenge X. This time, three different open-source language models were applied to the trolley problem. In each case, personalities were created with nationality, gender, and age. In addition, the data was compared with that of the MIT Moral Machine project. Sahan Hatemo, Christof Weickhardt, and Luca Gisler will present their results at the end of March or beginning of April 2025 in San Francisco, the venue of this year’s event.

Cute little AIBI

Prof. Dr. Oliver Bendel’s privately funded Social Robots Lab has been home to little AIBI since January 2025. It comes from the Chinese company LivingAI. Other robots and figures in the Social Robots Lab are Cupboo AI Robotic Pet aka Boo Boo, Unitree Go2, Alpha Mini, Cozmo, Vector, Furby, Tamagotchi, and Hugvie. HUGGIE was dismantled at the beginning of 2025 and given to a student project in which the robot laughs with a synthetic or natural voice. NAO and Pepper visit the lab and the elective module on social robots from time to time. AIBI has various sensors, a camera, and three microphones. It understands voice commands. For more complex questions, it connects to ChatGPT. The face consists of a display in which it can show animated eyes and animated scenes of all kinds. It stands on a platform that allows it to rotate 360 degrees. It can also turn its head freely. Similar to Cozmo, it emits numerous sounds and tries to attract the user’s attention in this and other ways. Thanks to its magnets, it can be attached to the fridge and other metal surfaces, as well as to an included necklace, transforming it into a wearable. It also transforms with accessories, for example into a cat. Robot enhancement is therefore included and supplied by the company.

The ICSR 2025 Website is Now Online

The ICSR is one of the leading conferences for social robotics worldwide. The 17th edition will take place from 10 to 12 September 2025 in Naples, Italy. The conference website is now online: icsr2025.eu. “The conference theme, ‘Emotivation at the Core: Empowering Social Robots to Inspire and Connect,’ highlights the essential role of ‘Emotivation’ in social robotics. Emotivation captures the synergy between emotion and motivation, where emotions trigger and sustain motivation during interactions. In social robotics, this concept is key to building trust, fostering empathy, and supporting decision-making by enabling robots to respond sensitively to human emotions, inspiring engagement and action.” (Website ICSR) The most important conferences dates are: Full Paper Submission: March 28th, 2025; Full Paper Notification: May 9th, 2025; Camera-ready: June 30th, 2025; Paper Presentation Days at ICSR’25: September 11th and 12th, 2025. All dates are also listed on the website. Participants will meet for two days at the Parthenope University of Naples and for the third day at the Città della Scienza conference center. All buildings and rooms are also listed on the website. Be part of this excellent conference (Photo: ICSR)!

22 Chatbots and Voice Assistants

Since 2013, Oliver Bendel has developed 22 chatbots and voice assistants together with his students or colleagues. They can be divided into three categories. The first are moral and immoral chatbots (i.e., forms of moral machines) and empathic voice assistants. The second are chatbots (some with voice output) for dead, endangered, or extinct languages and idioms. The third are pedagogical chatbots and chatbots that give recommendations and advice. Some of the projects lasted between four and six months. Most of the GPTs were created in just a few hours. Exceptions are Miss Tammy and Animal Whisperer, which took several months to build with the help of prompt engineering and retrieval-augmented generation (RAG). Articles and book chapters have been published on many of the projects. The names of the developers can be found in these. A few chatbots made it into the media, such as GOODBOT (for which the preparatory work began in 2012), LÜGENBOT aka LIEBOT, and @llegra.

Cleop@tr@ Visits the Karnak Temple

Cleop@tr@ was invented by Prof. Dr. Oliver Bendel in May 2024. It is a GPT that specializes in Egyptian. It is also familiar with the culture and history of ancient Egypt. Since 2012, the technology philosopher and information systems specialist has been building chatbots and voice assistants – partly with his students and partly on his own. These have been discussed by the media and found interesting by NASA. Under his supervision, Karim N’diaye developed the chatbot @ve for Latin, Dalil Jabou the voice-enhanced chatbot @llegra for Vallader, and Nicolas Lluis Araya the voice-enhanced chatbot kAIxo for Basque. For some time now, he has been testing the reach of GPTs for endangered languages such as Irish, Maori, and Basque. He is also investigating the potential for extinct languages such as Egyptian (Cleop@tr@) and Akkadian (H@mmur@pi). The GPTs do not readily communicate in hieroglyphics and cuneiform, but they can certainly represent and explain signs of visual languages. It is even possible to enter entire sentences and then ask how they can be improved or what they mean. In December 2024, Oliver Bendel tested his Cleop@tr@ in the Karnak Temple in Luxor. She was able to provide coherent explanations and translations for several inscriptions on columns and walls. However, further tests also revealed clear errors. Ultimately, Egyptologists will have to assess how reliable it is.

Role Player Nina

Around the turn of the millennium, there were already numerous pedagogical agents, i.e., chatbots, voice assistants, and early social robots in learning environments. Names such as Virtual Learning Companions (VLCs) were also commonly used for the purely virtual versions. One of the companies that was ahead of its time was Extempo Systems, Inc. based in Redwood City, California. The company had evolved out of the Stanford Engineering School and designed and developed commercial agents for entertainment, business, and education: “Extempo makes e-learning products that help corporate employees perfect their people skills. The company’s approach allows every learner to achieve mastery of the people skills they need for effective management, teamwork, sales, customer service, and other critical business functions. Extempo’s products give learners authentic practice in a variety of job-specific conversational role-plays, along with expert individualized coaching throughout the learning process.” (Extempo Systems) One example was the virtual Nina, with whom you could communicate and who you were supposed to motivate to behave in a certain way. It wasn’t just the functionality that was impressive at the time, but also the design of the characters.

Award for ACI Paper

“The Animal Whisperer Project” by Oliver Bendel (FHNW School of Business) and Nick Zbinden (FHNW School of Business) won the Honourable Mention Short Paper Award at the 2024 ACI Conference. From the abstract: “Generative AI has become widespread since 2022. Technical advancements have resulted in multimodal large language models and other AI models that generate, analyze, and evaluate texts, images, and sounds. Such capabilities can be helpful in encounters between humans and animals. For example, apps with generative AI on a smartphone can be used to assess the body language and behavior of animals – e.g., during a walk or hike – and provide a recommendation for human behavior. It is often useful to take into account the animal’s environment and situation. The apps can help people to avert approaches and attacks, and thus also protect animals. In ‘The Animal Whisperer Project’, three apps were developed as prototypes based on the multimodal large language model GPT-4 from OpenAI from the beginning to mid-2024. Three specific GPTs resulted: the Cow Whisperer, the Horse Whisperer, and the Dog Whisperer. All three showed impressive capabilities after the first prompt engineering. These were improved by implementing information from expert interviews and adding labeled images of animals and other materials. AI-based apps for interpreting body language, behavior, and the overall situation can apparently be created today, without much effort, in a low-budget project. However, turning them into products would certainly raise questions, such as liability in the event of accidents.” The proceedings are available here.
