  1. Investigating gender and racial biases in DALL-E Mini Images.Marc Cheong, Ehsan Abedin, Marinus Ferreira, Ritsaart Willem Reimann, Shalom Chalson, Pamela Robinson, Joanne Byrne, Leah Ruppanner, Mark Alfano & Colin Klein - forthcoming - Acm Journal on Responsible Computing.
    Generative artificial intelligence systems based on transformers, including both text-generators like GPT-4 and image generators like DALL-E 3, have recently entered the popular consciousness. These tools, while impressive, are liable to reproduce, exacerbate, and reinforce extant human social biases, such as gender and racial biases. In this paper, we systematically review the extent to which DALL-E Mini suffers from this problem. In line with the Model Card published alongside DALL-E Mini by its creators, we find that the images it produces (...)

  2. Inscrutable Processes: Algorithms, Agency, and Divisions of Deliberative Labour.Marinus Ferreira - 2021 - Journal of Applied Philosophy 38 (4):646-661.
    As the use of algorithmic decision‐making becomes more commonplace, so too does the worry that these algorithms are often inscrutable and our use of them is a threat to our agency. Since we do not understand why an inscrutable process recommends one option over another, we lose our ability to judge whether the guidance is appropriate and are vulnerable to being led astray. In response, I claim that a process being inscrutable does not automatically make its guidance inappropriate. This phenomenon (...)

  3. Reactionary attitudes: Strawson, Twitter, and the Black Lives Matter Movement.Anastasia Chan, Marinus Ferreira & Mark Alfano - forthcoming - In Fernando Aguiar-Gonzalez & Antonio Gaitan (eds.), Experimental Methods in Moral Philosophy. Routledge.
    On 25 May 2020, Officer Derek Chauvin asphyxiated George Floyd in Minneapolis — a murder that was captured in a confronting nine-minute bystander video that set off a firestorm of activity on online social networks, in the streets of the United States, and even worldwide. These protests captured the collective rage, dissatisfaction, and resentment personally and vicariously experienced towards the widespread systematic injustice and mistreatment of African Americans by police and vigilantes. The scale of these protests, both online and in (...)

  4. The wisdom-of-crowds: an efficient, philosophically-validated, social epistemological network profiling toolkit.Colin Klein, Marc Cheong, Marinus Ferreira, Emily Sullivan & Mark Alfano - 2023 - In Hocine Cherifi, Rosario Nunzio Mantegna, Luis M. Rocha, Chantal Cherifi & Salvatore Micciche (eds.), Complex Networks & Their Applications XI: Proceedings of The Eleventh International Conference on Complex Networks and their Applications: COMPLEX NETWORKS 2022 - Volume 1. Springer.
    The epistemic position of an agent often depends on their position in a larger network of other agents who provide them with information. In general, agents are better off if they have diverse and independent sources. Sullivan et al. [19] developed a method for quantitatively characterizing the epistemic position of individuals in a network that takes into account both diversity and independence; and presented a proof-of-concept, closed-source implementation on a small graph derived from Twitter data [19]. This paper reports on (...)

    Exploring intellectual humility through the lens of artificial intelligence: Top terms, features and a predictive model.Ehsan Abedin, Marinus Ferreira, Ritsaart Reimann, Marc Cheong, Igor Grossmann & Mark Alfano - 2023 - Acta Psychologica 238 (103979).
    Intellectual humility (IH) is often conceived as the recognition of, and appropriate response to, your own intellectual limitations. As far as we are aware, only a handful of studies look at interventions to increase IH – e.g. through journalling – and no study so far explores the extent to which having high or low IH can be predicted. This paper uses machine learning and natural language processing techniques to develop a predictive model for IH and identify top terms and features (...)

  6. Limited Conventions about Morals.Marinus Ferreira - 2017 - Dissertation, University of Auckland
    n this thesis I describe how conventions specify how to put normative principles into practice. I identify a class of recurring situations where there are some given normative principles in effect, but they underdetermine what each individual should do, and what is best for an individual depends on what others do. I demonstrate that in such cases, whenever the community develops a response that repeatedly brings them to as good an outcome as is available according to their principles, that response (...)

  7. A tragic coalition of the rational and irrational: a threat to collective responses to COVID-19.Marinus Ferreira, Marc Cheong, Colin Klein & Mark Alfano - 2022 - Philosophical Psychology (6).
    There is not as much resistance to COVID-19 mitigation as there seems, but there are structural features that make resistance seem worse than it is. Here we describe two ways that the problem seeming to be worse than it is can make it worse. First, visible hesitation to implement COVID-19 responses signals to the wider society that mitigation measures may not succeed, which undermines people’s conditional willingness to join in on those efforts. Second, our evaluations of others’ willingness to implement (...)

  8. Attention and counter-framing in the Black Lives Matter movement on Twitter.Colin Klein, Ritsaart Reimann, Ignacio Ojea Quintana, Marc Cheong, Marinus Ferreira & Mark Alfano - 2022 - Humanities and Social Sciences Communications 9 (367).
    The social media platform Twitter platform has played a crucial role in the Black Lives Matter (BLM) movement. The immediate, flexible nature of tweets plays a crucial role both in spreading information about the movement’s aims and in organizing individual protests. Twitter has also played an important role in the right-wing reaction to BLM, providing a means to reframe and recontextualize activists’ claims in a more sinister light. The ability to bring about social change depends on the balance of these (...)
