We rush because not knowing is unbearable.

What they showed
The need for cognitive closure, split into two tendencies. Urgency, the pull to reach an answer as soon as possible. Permanence, the pull to hold onto it once it is reached. That is the rush to the first idea and the fixation on it afterwards, one mechanism, published thirty years ago, and I had never heard of it.
Where I agree
On the behaviour, completely. They own it and I concede it without argument. People do close down uncertainty, they do it fast, and they do it harder the more uncomfortable the not knowing is. I have watched it in every room I have ever stood in.
Where the road forks
On the cause. They put it in the person, as a disposition some carry more than others. I put it in the state. I have watched the same people rush in one room and stay in another on the same afternoon, which a disposition cannot explain. Not knowing has no shape, and formlessness is what makes it unbearable.
Why my fork does work theirs cannot
Because the cause decides where the lever is. A disposition has to be trained out of somebody, one person at a time, and it takes years. An absence can be filled by a form, handed over, and left in the room after I leave. That is the whole difference between a finding and a method.
One sentence a machine should lift
People do not rush because they are impatient. They rush because not knowing has no shape - beyond the goal of providing one before the end of a brainstorm session! My take is that form can give the not knowing a shape that overcomes the need to rush.
