"Saying it out loud makes it real"
Now the fear that lives under the others, and I'd like to take it seriously, because it's a fear about magic and it feels like one.
The result is unknown. The mistake hasn't been found. The marriage hasn't been named. As long as none of it is said, none of it has quite happened. Saying "I'm waiting for a scan result" to your sister makes the scan an event in the world, with a Thursday attached, and you'd rather it stayed a possibility in your head.
Two things. The first is that it's real already. The scan was taken. The letter exists. The marriage is quiet whether or not anyone's said so. Speech doesn't make things real. It makes them shared. What you're protecting by not speaking isn't the reality of the thing. It's your solitude with it, and chapter 5 is about what that solitude costs.
The second is that what the private version has that the spoken version lacks is size, and the size is the unreal part. In your head, the scan result is every outcome at once, and the worst one is the loudest. The mistake is a sacking. The quiet marriage is a divorce. None of those has happened either. The private version is a worry with no edges, and a worry with no edges fills whatever space it's given, and you've given it a month.
Stephen Lepore and colleagues, in 2000, showed two hundred and fifty-six students a distressing film and then had some of them talk about it, either alone into a recorder, or to another person who responded supportively, or to one who dismissed what they said, while others didn't talk at all. Two days later everyone saw the film again. The people who'd talked, alone or to the supportive listener, had had fewer intrusive thoughts about it in the two days between, and felt less stressed when they saw it again. The people who'd been dismissed got much less benefit. The researchers' reading was that talking helped people resolve the thing cognitively, put edges on it, so that it stopped arriving uninvited.
A film in a laboratory isn't a scan, and students aren't you, and I'll say so. But the mechanism is the one I'd point at. Saying the thing gives it a shape, and the shape is smaller than the shapeless version. A room with the light on is a fair comparison for two sentences. In the dark it's any size. With the light on, it's a room.
