A subtle aspect of predictive modeling is target variable construction: the process of translating a latent, unobservable concept like "healthcare need" into a prediction target
But how does target variable construction unfold in practice, and how can we better support it going forward? #CSCW2025 🧵

✨I’m on the academic job market ✨
I’m a PhD candidate at @hcii.cmu.edu studying tech, labor, and resistance 👩🏻💻💪🏽💥
I research how workers and communities contest harmful sociotechnical systems and shape alternative futures through everyday resistance and collective action

What can #CSCW learn from tech workers who have been involved in collective action and unionization about how to make transformative change within our field?
My new #CSCW2025 paper with Mona Wang, Anna Konvicka, and Sarah Fox seeks to answer this question.
