Suicide prevention confronts a prediction problem
The Science of Suicide Prevention, with Matthew Nock, PhD
Suicide remains difficult to prevent because clinicians must act on serious risk despite limited ability to predict who will attempt it.
- 1Suicide rates have resisted broad medical progress, while suicidal thoughts and distress have increased among some young people.
- 2Existing risk assessments cannot reliably predict rare suicidal behavior, making thorough evaluation and immediate safety support essential.
- 3Evidence-based therapy, digital data, and direct compassionate conversations offer complementary ways to reduce risk and connect people with help.
Don't miss
Nock directly addresses the fear that asking about suicide could cause harm, explaining why compassionate questions can support prevention.
The brief
Matthew Nock explains why U.S. suicide rates have barely changed over roughly a century, even as medicine has reduced many other causes of death.
Risk varies across ages and populations, but prediction remains difficult: suicidal behavior is relatively rare, and familiar risk factors cannot identify precisely who will act.
Nock reviews cognitive therapy, cognitive behavioral therapy, and different levels of care, emphasizing thorough assessment and immediate safety support when danger is acute.
Electronic health records and smartphone sensors may improve prediction and prevention, while chatbots remain tools whose effects depend on how people use them.
The most practical guidance is also the most direct: asking someone about suicide does not cause suicidal behavior and can open a compassionate path to help.
