Given the difficulty of directly debiasing cognitive and social biases, Ariella's research focuses on how environments can be structured to reduce biased behaviors and outcomes. Ariella is currently pursuing two main strands of research: the first is a focus on understanding how people's beliefs related to various self-control strategies affect goal achievement, and the second is a focus on increasing diversity and inclusion in the workplace.
