memory

You misremember when events in your life actually happened.

The telescoping effect causes people to shift distant events forward in time and recent events further back.

In a 1987 study, researchers found that memories of events over a year old tend to be pulled toward the present, while very recent events feel more distant than they are. This bias makes your personal timeline feel compressed. You essentially lose the ability to accurately date your own past experiences as they drift from the present.

Your personal history is a collection of memories that rarely sits in its proper place.
