racial microaggressions

Racial microaggressions are subtle, brief, and commonplace verbal, behavioral, or environmental indignities that communicate hostile, derogatory, or negative slights and insults toward members of racial or ethnic minority groups. These interactions can be intentional or unintentional, frequently arising from implicit biases, stereotypes, or unexamined assumptions rather than overt hostility. They commonly manifest as dismissive remarks, backhanded compliments, exclusionary behavior, or the denial of a person of color's cultural identity and lived experiences. While individual occurrences may seem minor or ambiguous to an outside observer, the continuous and cumulative nature of these everyday slights can cause significant psychological stress, perpetuate racial stereotypes, and reinforce systemic marginalization.

Introduces ToxiGen, a large-scale balanced dataset of over 274,000 machine-generated statements across 13 minority groups, along with an adversarial decoding method to help classifiers detect subtle, implicit hate speech without over-relying on identity mentions.

Toxic language detection systems often falsely flag text that contains minority group mentions as toxic, as those groups are often the targets of online hate. Such over-reliance on spurious correlations also causes systems to struggle with detecting implicitly toxic language. To help mitigate these issues, we create TOXIGEN, a new large-scale and machine-generated dataset of 274k toxic and benign statements about 13 minority groups. We develop a demonstration-based prompting framework and an adversarial classifier-in-the-loop decoding method to generate subtly toxic and benign text with a massive pretrained language model (Brown et al., 2020). Controlling machine generation in this way allows TOXIGEN to cover implicitly toxic text at a larger scale, and about more demographic groups, than previous resources of human-written text. We conduct a human evaluation on a challenging subset of TOXIGEN and find that annotators struggle to distinguish machine-generated text from human-written language. We also find that 94.5% of toxic examples are labeled as hate speech by human annotators. Using three publicly-available datasets, we show that finetuning a toxicity classifier on our data improves its performance on human-written data substantially. We also demonstrate that TOXIGEN can be used to fight machine-generated toxicity as finetuning improves the classifier significantly on our evaluation subset.
