Here's how it works: Instead of mentally screaming Shut up! Shut up! Shut Up! at whatever childhood trauma or embarrassing moment keeps surfacing, you simply bring to mind another memory instead, reports Forbes.
In the past, researchers at the University of Cambridge found that asking yourself to recall an alternative memory from your past causes you to passively forget said memory that just keeps sliding into your mental DMs. And now, a recent study published by the same team in Nature Communications has gone one step further to find that actually, you actively extinguish the unwanted recall through this process, which is called retrieval-induced forgetting.
This replacement method could also work for songs or jingles that get stuck in your head (AKA, earworms), too. Because although Ariana Grande's new #girlpower anthem is jammy, it might get old after your brain replays it for the umpteen-millionth times. And finally, you might consider using the same replacement logic for your exes. Consider this another vote for the old saying, "You can’t really get over one person until you get under another."
