“You knew exactly
what you came for.
Until you didn’t.”
The Doorway Effect is a well-documented cognitive phenomenon: passing through a doorway causes your brain to compartmentalise, filing away the thought you were carrying in a separate mental episode. The new room becomes a new context, and the old intention fades. It happens dozens of times a day. Every app you open to “remember something” becomes another doorway. Presence is built around this. Capture before the threshold. Not after.
