Out of 1000 calls I had one person attempt, maybe 10 people decide not to attempt, and the rest were just people who were anxious or sad or scared and were having thoughts.
There's a very broad spectrum, and for someone who is hopeless or just lonely and sad, talking to a caring human who listens and is comfortable with your pain does help, yes.
For people in a crisis, having someone calm who can talk through what's happening without panicking helps, yes.
I'm curious where you're coming from on this, as I don't understand the perspective behind your comment.
