Why you forget what you're doing after walking into a room
Briefly

The phenomenon known as the 'doorway effect' causes people to forget their intentions upon entering new rooms, as explained by cognitive neuroscientist Christian Jarrett. This is because the brain compartmentalizes information based on context; when moving through doorways, the brain slightly resets, leading to memory lapses. A study from the University of Queensland supports this idea, showing that distractions amplify the effect. To counter this, Jarrett suggests staying focused on one's purpose and even writing reminders, such as on the back of one's hand.
Experts have revealed that these so-called 'brain farts' are not anything to be concerned about - in fact, they are the result of a perfectly normal brain response to new surroundings.
According to ​Christian Jarrett, this phenomenon called the 'doorway effect' happens because our brain naturally compartmentalises activities and information based on environmental contexts.
The Queensland team said this chimes with everyday experience in that it's mostly when we're distracted, with our mind on other things, that we're inclined to forget.
Try to stay focused on your purpose when you pass through a doorway on an errand; it may be useful to make a note on the back of your hand.
