Walking into your kitchen just made you forget why you went there.
That's not forgetfulness. That's your brain doing exactly what it's built to do.
In 2011, researchers at Notre Dame had people carry objects from one room to another. Some walked through a doorway. Others covered the same distance without crossing one. The doorway group forgot their task two to three times more often.
Every door in your home works this way. Walk from your bedroom to your kitchen and your brain quietly closes the file on what you were just thinking. Your plan, your reminder, your reason for walking — gone before you land in the new room.
You can look at this as a vote for separate rooms or for open plans depending on your use case. But if you do have separate rooms and you're finding yourself forgetting between rooms, the fix is to say your task out loud right before you cross the threshold (quietly to yourself also works). Or write it down first. Don't trust your brain to carry it through the door — it won't.
