Our ability to collect and record information in a digital form has exploded as has our adoption of AI systems, which use data to make decisions. But data isnt neutral, and sexism, racism and other forms of discrimination are showing up in our data products. Catherine DIgnazio, an assistant professor of urban science and planning at the Massachusetts Institute of Technology (MIT), argues we need to do better. Along with Lauren Klein, who directs the Digital Humanities Lab at Emory University, she is the co-author of the new book Data Feminism, which charts a course for a more equitable data science. DIgnazio also directs MITs new Data and Feminism lab, which seeks to use data and computation to counter oppression.

What is data feminism and why do we need it?It is data science with an intersectional feminist lens. It takes all inequality into account at every stage of the data processing pipeline, including gender discrimination but also other forms of intersecting discrimination like racism, classism and ableism. And the reason we need it is to stop producing harmful racist and sexist data products.

We shouldnt be surprised about the sexist results coming out of these algorithms with the flawed data we are feeding in

When you look at data and AI this way, what kind of problems do you find?We find some people are winning and some people are losing. The benefits and harms are not being equally distributed. And those who are losing are disproportionately women, people of colour, and other marginalised groups. One way they are losing is that data most of us would think is important isnt being collected. We have detailed datasets on things like the length of guinea pig teeth and items lost on the New York City subway. But, in the US, missing data includes maternal mortality data, which has only started being collected recently, and sexual harassment data. And so much of our health and medical understanding is based on research that has been done exclusively on the male body.

How do people with less privilege show up in datasets?Weve had facial analysis software that is much less accurate for dark-skinned women and algorithms that disadvantage female applicants. Weve also had child abuse prediction software that over-targets poor families and predictive policing software like PredPol that disproportionately targets neighbourhoods of colour. The former pulls data from state health and welfare services, which poor people are more likely to access, while the latter is based on historical crime data; only US policing practices have always disproportionately surveilled and patrolled neighbourhoods of colour. We shouldnt be surprised about the racist and sexist results coming out of these algorithms with the deeply flawed data we are feeding in.

If our data and algorithms are all so flawed, how do we change things to make them better?First we need to be tuning in to the ways that oppressive forces might be insidiously inserting themselves into the data pipeline. More understanding is particularly needed among the technical folks who are making these systems. It is rarely the case that the discrimination in products is intentional; its just that nobody has ever taught them that it is a problem or emphasised that it is important. University data-science courses should include more than just a single ethics class.

Then we have to actually use data and computation to challenge inequality. We have to collect counter-data. Take for example the comprehensive dataset on Mexicos femicides gender-related killings of women and girls that has been compiled for the past five years from media reports by Mara Salguero, a citizen activist in that country. She is filling a vacuum because the Mexican government is not collecting the data. Now of course data alone is never enough. But if the data is used in concert with organising, lobbying and building political will, it can be very effective. In the US, we do have organisations working to call out injustice and produce their own counter-data, including Data for Black Lives, the Algorithmic Justice League and The Markup. We need to fund more of this kind of work.

Is there such thing as neutral data?There is a naive assumption that if you see numbers in a spreadsheet, they are real somehow. But data is never this raw, truthful input, and it is never neutral. It is information that has been collected in certain ways by certain actors and institutions for certain reasons. For example, there is a comprehensive database at the US federal level of sexual assaults on college campuses colleges are required to report it. But whether students come forward to make those reports will depend on whether the college has a climate that will support survivors. Most colleges are not doing enough, and so we have vast underreporting of those crimes. It is not that data is evil or never useful, but the numbers should never be allowed to speak for themselves because they dont tell the whole story when there are power imbalances in the collection environment.

Would data sciences bias problems be solved if there were simply more data scientists, coders and computer programmers who were women or from minority backgrounds?More diversity is an important part of the solution. As a group, data scientists are more likely to be male, white and highly educated. They have never experienced sexism, racism or classism so it is hard for them to see it. We call this the privilege hazard in the book and diversity can mitigate it.

But only including more women or people of colour is not going to solve everything. We need to put communities who will be impacted by the information systems into the process of making them. Because inevitably designers and programmers are going to be building systems for life experiences that they havent had. If everyone that builds a welfare application needs to have lived on welfare, that would be a high bar. Because I am a woman doesnt mean Im going to understand how to build an application for domestic workers. But there are participation strategies from other fields like urban planning and how we incorporate those in data science is an area ripe for exploration.

In the book you talk about Big Dick Data. What is it and should we just reject it outright?We coined it to denote big data projects that are characterised by masculine fantasies of world domination. Big Dick Data projects fetishise large size and prioritise it, along with speed, over quality, ignore context and inflate their technical capabilities. They also tend to have little consideration for inequalities or inclusion in the process. Mark Zuckerberg aiming to supersede human senses with AI might be considered one such project, along with software company Palantirs claims about massive-scale datasets. Big Dick Data projects arent necessarily wholly invalid, but they suck up resources that could be given smaller, more inclusive projects.

What would you most like people to think about or ask themselves when they encounter data or a graph in the media?A good general strategy and feminist practice is to ask what we call who questions. Who made this? Who collected the data? Whose lives are embodied in the data? Who is it serving? Who is harmed potentially? Asking these questions allows us to start to see how privilege is baked in.

How is privilege being baked into the coronavirus data we are collecting?The US governments response to coronavirus has been a case of missing data. There has been community spread, but the numbers are completely unreliable because kits are in short supply and people are having a hard time getting tests. And then poor people, which include many from immigrant backgrounds, will be less likely to seek tests because of lack of insurance, lack of ability to afford insurance co-pays and lack of paid sick time if they test positive.
