Creating more equitable justice to reduce mass incarceration

Our goal is to prevent 500,000 missed court dates, and their resulting warrants and jail
time, over the next five years.

Today, people all over the country will miss an appointment: it happens to everyone. Missing an appointment is an accepted, forgivable part of life; unless, of course, you miss a court date. Missing court, even for low-level charges like traffic violations or open alcohol containers, can lead to fines, warrants, jail, and other significant consequences. In short, missed court dates can disrupt jobs and housing, harm well-being, and “mark” individuals for the rest of their lives.

This problem is so large that more people are in jail for missing court than any other reason in areas across the United States. And warrants disproportionately harm people of color: Black individuals are three to four times more likely to get arrested and jailed.

Our proven solution is simple yet transformational: reimagine and reform the communications people receive about their court dates using behavioral science.

Our work is already preventing tens of thousands of missed court dates. By helping people better understand, remember, and ultimately show up to court using principles from behavioral science and procedural justice, we've seen a 36% reduction in missed court dates. Our solution creates the greatest benefit for those most impacted by the system: communities with low wealth and people of color.

We are scaling this solution because a child having a parent in jail or a worker losing their job
simply because of a missed court date is unjustifiable—it's unwarranted.

Partnering with us

(Un)warranted, an initiative of ideas42's Safety & Justice team, is a hub of expertise that creates positive change—bringing our proven experience to reduce nonappearance and its harmful consequences. We do so by reforming court date communications and catalyzing evidence-based policy.

Our work is actively informed both by people impacted by the system and organizations serving local communities. It is also not possible without the financial support of individuals and organizations who deeply believe in the ways (Un)warranted is striving for change.
