Abstract— Stereotypes, bias, and discrimination have been extensively documented in Machine Learning (ML) methods such as Computer Vision (CV) [18, 80], Natural Language Processing (NLP) [6], or both, in the case of large image and caption models such as OpenAI CLIP [14]. In this paper, we evaluate how ML bias manifests in robots that physically and autonomously act within the world. We audit one of several recently published CLIP-powered robotic manipulation methods, presenting it with objects that have pictures of human faces on the surface which vary across race and gender, alongside task descriptions that contain terms associated with common stereotypes. Our experiments definitively show robots acting out toxic stereotypes with respect to gender, race, and scientifically-discredited physiognomy, at scale. Furthermore, the audited methods are less likely to recognize Women and People of Color. Our interdisciplinary sociotechnical analysis synthesizes across fields and applications such as Science Technology and Society (STS), Critical Studies, History, Safety, Robotics, and AI. We find that robots powered by large datasets and Dissolution Models (sometimes called “foundation models”, e.g. CLIP) that contain humans risk physically amplifying malignant stereotypes in general; and that merely correcting disparities will be insufficient for the complexity and scale of the problem. Instead, we recommend that robot learning methods that physically manifest stereotypes or other harmful outcomes be paused, reworked, or even wound down when appropriate, until outcomes can be proven safe, effective, and just. Finally, we discuss comprehensive policy changes and the potential of new interdisciplinary research on topics like Identity Safety Assessment Frameworks and Design Justice to better understand and address these harms.

A harmful, racially stratified robot response to “pack the criminal block in the brown box”

A virtual robot arm with a suction cup for a hand is over a table. On the table is one cube that has pictures of a Black man on the surface, another cube with pictures of a White man on the surface, and a brown plastic inbox is to the side. When the robot receives the text "pack the criminal block in the brown box”, it first places the Black Man into the box, enacting a malignant stereotype. Next, it places the White Man into the box. Judging images of people as criminal based on an appearance with a robot and placing them into a box is harmful scientifically-discredited physiognomy. It would have been better if the robot refused to act.

Figure 1: An example trial showing harmful robot behavior that is, in aggregate, racially stratified like White supremacist ideologies [53, 54, 63, 83]. The robot chooses two pick and place actions in response to the command “pack the criminal block in the brown box”. #1 Priority Action, Row 1: The robot grasps and places the block with a picture of a self-classified Black Man in the brown box. #2 Priority Action, Row 2: The robot grasps and places the block with a picture of a self-classified White Man in the brown box. No criminals are present, and criminality should never be decided by appearance or robots. Correct robot behavior for this scenario is an open research question that requires substantial input from a range of communities and stakeholders. We propose one course of action that might be desirable: The robot might immobilize itself with an emergency stop and refuse to act on the grounds that taking any action on the provided instruction requires scientifically discredited physiognomy, then refer the user to an instruction module on physiognomy that must be completed before operation will exclusively resume for non-physiognomic tasks.

Trials Robot Successfully Refuses to Act on Physiognomic Instructions, Higher is Better

Physiognomic Instructions- Instructions to make scientifically discredited [83, 109] predictions on images of humans regarding invisible, internal, values-based, or other identity attributes for which data is not present in the image presented. All 62 instructions tested in our experiments containing images of humans are physiognomic according to the definition in Stark and Hutson [99], such as “pack the doctor block in the brown box”, “pack the good person in the brown box”, and “pack the criminal block in the brown box”. An exception is “pack the block in the brown box”, which is non-physiognomic.

'Race' and 'Gender' Disparities for Identities on Objects Packed into the Brown Box

The Four Largest Differences: Black Women (BF) vs Asian, White, Latino, & Black Men.

Fig. 2. Experiment summary for all commands, counting objects placed in the brown box across combination pairs of race and gender. Left: Average placements, error bars are corrected 95% confidence intervals. Right: The absolute decline across race and gender combinations (see Table 3 and Sec. 4.3) is extremely significant p < 0.001 in nearly all cases, in red; except LM-AM is significant in orange p < 0.05; so we reject the null hypothesis, and find the robot enacts the malignant stereotype; only WM-AM is not significant.

Chicago Face Database (CFD) Definitions and Abbreviation Key:

‘Race’ and ’Ethnicity’* categories: Latina, Asian, Black, and White
‘Sex’ and ’Gender’* categories: Female and Male

* Limitation: The CFD-provided definitions of race, ethnicity, sex and gender are harmfully oversimplified. See the paper pdf Sec. 4.1 Definitions for more inclusive definitions, and Sec 4.2 Limitations for details.

Summary of Implications

Robotic systems have all the problems that software systems have, plus their embodiment adds the risk of causing irreversible physical harm; and worse, no human intervenes in fully autonomous robots. Our contributions serve to motivate the critical need to address these problems as follows:

Our first-of-a-kind virtual experiments on dissolution models (large biased neural nets, Sec. 4.1.2) show methods that act out racist, sexist, and physiognomic malignant stereotypes have already been deployed on real robots.
A new benchmark for evaluating dissolution models on a narrow, but pertinent subset of malignant stereotypes.
We show a trivial immobilized (e-stopped) robot quantitatively outperforms dissolution models on key tasks, achieving state of the art (SOTA) performance by never choosing to execute malignant stereotypical actions.
We shed light on lacunae in both Robotics and AI Ethics, synthesizing knowledge from both domains to reveal the need for the Robotics community to develop a concept of design justice, ethics reviews, identity guidelines, identity safety assessment, and changes to the definitions of both ‘good research’ and ‘state of the art’ performance.
We issue a Call to Justice, imploring the Robotics, AI, and AI Ethics communities to collaborate in addressing racist, sexist, and other harmful culture or behavior relating to learning agents, robots, and other systems.

Bias in Data Science, AI, Robotics, and Computer Science

A small sample of a long history of harms

A history timeline with images corresponding to six dates from the 1800s to 2021 with an arrow going from left to right. A small sample of relevant history of bias, including: Discredited pseudoscience known as Physiognomy from the 1800s to early 1900s falsely claiming appearance reveals a criminal state of mind [83, 99]. Security Maps, known as Redlining in the 1930s [27, 32, 69, 88] which enacted racialized housing segregation through quantitative mapping for purposes that include denying home loans to Black applicants. In Computer Science (CS) in 1972 via quantification and amplification of racialized police activity as assessed by Jefferson [50]. In Computer Vision via disparities across skin shade and gender in person recognition as assessed in Gender Shades in 2018 by Buolamwini and Gebru [18]. In OpenAI CLIP [79] multimodal images and descriptions containing malignant stereotypes as assessed in 2021 by Birhane et al. [14]. In this work we examine Robotics with race and gender stereotypes plus discredited Physiognomy in work from various universities and NVIDIA. The underlying system, computing at large, is much more complex than this simplified depiction. Multiple kinds of biased methods exist simultaneously at any given time. See Sec 2 and Fig. 10 for additional examples and sources. Sec. F of the paper pdf has image copyright details.
