Ask someone who seems emotionally distressed directly "Have you had thoughts of suicide?"—asking will not plant the idea or increase suicidal risk

The widespread fear that asking someone about suicide puts the idea in their head is directly refuted by scientific evidence. In randomized trials where high school students were asked detailed questions about suicidal ideation, participants experienced no increase in distress and no rise in suicidal thoughts compared to unasked peers. In fact, students with existing depressive symptoms reported less distress, and those with previous suicide attempts experienced a measurable decrease in suicidal ideation.

Zero financial cost. Asking takes seconds, followed by taking time to listen attentively without judgment. The primary difficulty is psychological hesitation, as many people fear that mentioning suicide will introduce the thought into someone's mind.

In a randomized controlled trial published in JAMA involving 2,342 students across six New York high schools, classrooms were randomly assigned to complete a survey that either included or omitted explicit questions regarding suicidal ideation. Immediately following the survey and at two-day follow-up, emotional distress levels showed no statistically significant difference between groups (P = .66 and P = .41). Two days later, reported suicidal ideation was 4.7% in the surveyed group versus 3.9% in the unasked group—a statistically indistinguishable difference (P = .49). Crucially, students who were already experiencing depressive symptoms experienced significantly lower distress after being asked (P = .01), and individuals with prior suicide attempts showed a significant reduction in subsequent suicidal thoughts (P = .02). A 2022 systematic review and meta-analysis evaluating 17 studies pooled 8 comparative trials of asked versus unasked participants: screening or directly inquiring about suicide did not produce any significant increase in immediate or subsequent suicidal ideation, suicide attempts, non-suicidal self-injury, or psychological distress. Across 8 randomized controlled trials evaluated, risk of bias was low or unclear. An earlier 2014 systematic review in Psychological Medicine arrived at identical conclusions: zero identified studies demonstrated an increase in suicidal ideation following direct questioning.

Grade B is assigned because while trials conclusively prove that direct inquiry causes no harm, trials cannot ethically measure reductions in completed suicides. Benefit magnitude is rated Low because it reflects surrogate endpoints (ideation frequency rather than absolute mortality counts). Most trial protocols utilized clinical interviews or standardized screening questionnaires rather than informal peer conversations, though clinical guidelines generalize this finding to friends and family. If someone confirms they are having suicidal thoughts, do not leave them unattended: stay with them, connect them immediately to a crisis helpline (such as 988 in the US/Canada or 12356/111 nationally), and remove access to lethal means (medications, sharp objects, chemicals), as outlined in Chapter 1, Rule 25. If they express intent to harm others or have active preparations underway, immediate emergency services or hospital evaluation is necessary, as described in Chapter 8, Rule 15. The interval between acute ideation and action is often mere minutes, as noted in Chapter 1, Rule 32. Primary beneficiaries are family members, partners, friends, and colleagues.
