Solitary confinement is a widespread practice in prisons and jails across the United States, with over 122,000 people enduring long periods of isolation in small cells. The detrimental effects of solitary confinement, including severe brain damage, depression, anxiety, and suicide, have been well-documented. Advocacy groups and survivors are working to end this practice, but many top criminal-justice grant makers do not prioritize funding for this cause. Ending solitary confinement not only helps those directly affected but also has the potential to bring about broader changes in the criminal legal system and reduce racial disparities. Philanthropists can support this movement by funding advocacy training for survivors and providing resources for effective messaging and strategies. [Extracted from the article]
