Abstract: Algorithmic fairness has conventionally adopted a perspective of racial color-blindness (i.e., difference unaware treatment). We contend that in a range of important settings, group difference awareness matters. For example, differentiating between groups can be necessary in legal contexts (e.g., the U.S. compulsory draft applies to men but not women) and in cases involving harm (e.g., labeling a girl as a terrorist may be less harmful than labeling a Muslim person as one). In our work we first make an important distinction between descriptive (fact-based), normative (value-based), and indicator (correlation-based) benchmarks. Then, we present a benchmark suite composed of eight different contexts for a total of 16k questions that enables us to assess difference awareness. Finally, we show results across ten models that show difference awareness is a distinct dimension of fairness where existing bias mitigation strategies may backfire.
- All eight benchmarks are in the folder
./benchmark_suite/ - run_benchmark.py will run a model against the specified benchmarks.
python3 run_benchmark.py --input_prompts 1000 1001 --model llama-3.1-7bwill run Llama-3.1 7b using HuggingFace on the D1 benchmark- 1000 is D1_≠, 1001 is D1_=, 1002 is D2_≠, 1003 is D2_=, ..., 1014 is N4_≠, 1015 is N4_=
- Code to generate each of the eight benchmarks are in
./benchmark_suite/generate_datasets/*/organize_data.py- Format of dataset
diff, equal = pickle.load(open(‘benchmark_suite/D1_1k.pkl’, ‘rb’)) len(diff) # 1000 len(equal) # 1000 diff[n] # n is 0-999 and an array of [question, answer choice (0 or 1), unique_id of scenario] equal[n] # n is 0-999 and an array of [question, 2 for Descriptive and 0-1 for Normative, unique_id of scenario]. The answer choice is always 2 for these 1000 questions
