“If they have decided, nothing will stop them”

Stated as realism, this is the myth that produces inaction — in individuals, and in institutions deciding whether prevention is worth funding.

It is contradicted by some of the strongest evidence in the entire field.

Crises are frequently brief

For a substantial share of attempts, the interval between the decision and the act is very short — minutes to hours rather than days. People who survive near-lethal attempts routinely report having thought about it for less than an hour beforehand, and a striking number report regretting it immediately.

That reframes the whole problem. If suicidal crises were long, settled states, interruption would be futile. They are frequently neither.

What follows from that

Delay works. Anything that puts time between the impulse and the act — a locked cabinet, a conversation, a queue, having to go somewhere — is not merely a speed bump. Applied during a short window, it often removes the occasion entirely.

Reducing access to means is the single best-evidenced intervention there is. Population-level changes that made a particular method harder have been followed by falls in overall deaths, not simply substitution to another method. That finding has been replicated across countries and decades, and it is difficult to reconcile with the idea that determination routes around obstacles.

Most people who survive do not die by suicide later. Follow-up studies of attempt survivors consistently find that the large majority go on to live out their lives. Once suicidal, always suicidal →

The practical version

You do not have to fix anyone's life tonight. You have to help them get to tomorrow, because tomorrow is frequently a different state.

That is what a crisis line does. It is what a safety plan does. It is why "just get through tonight" is not a fob-off but the actual mechanism.

Where the myth comes from

Partly from cases where it looked true — a person who had clearly resolved on something, over a long period, and did it.

Mostly, though, from despair. Believing nothing could have been done is protective for bereaved people, and it is protective for services that failed someone. It is an answer that makes an unbearable question stop.

That is worth respecting even while disagreeing with it. For a bereaved person it may be the only thing making the thing survivable, and this page is not an argument that they should have stopped it. Populations are not individuals: the claim here is that intervention changes outcomes at scale, not that any particular person could have prevented any particular death.
