Walking through a doorway really can make you forget why you came into the room.
In experiments, people who carried objects between rooms in a virtual or real building were worse at remembering what they held than people who walked the same distance within one room. Psychologists call it the doorway effect.
Why is this true?
The brain treats a doorway as the end of one event and the start of another, and files away what happened before. Going back to the first room often brings the memory back.

Psychology facts describe the shortcuts your mind takes without asking permission. We misjudge randomness, remember interrupted tasks better than finished ones, and change our answers when a group disagrees with us. The entries here stick to findings that have held up under replication, avoid the pop-science versions that overstate them, and explain what the effect really predicts about everyday behaviour.
