The more collective the harm, the less people are protected and the less visible it is. The more the harm is individual, the more visible its impacts are and the more people are legally protected. If a person is discriminated against because of protected characteristics such as their age, gender or ethnicity, it will be visible to them and they will hopefully be in a position to seek redress. When a person is discriminated against due to an algorithmic decision, it is likely to be less visible and, currently, hard to seek redress.
