Memory ’s ungovernable , a ceaseless shaming pain : you ’re either scrambling to retrieve it ( rooting around for keys , or the name of some conversance ) or you ’re scrambling away from it , wishing it would n’t pitch up , for the seven hundredth time , this or that low-down incident ( expiry , bad dates , clumsy lift talking , trauma beyond the compass and note of this parenthetical , etc . ) . Eternal Sunshine deposit a aesculapian remedy for this latter bane — but is such a thing actually possible , outside of niminy-piminy fake - indie movie from the early nil ? Can you in reality forget things on purpose ? For this week’sGiz Asks , we reached out a number of psychologist with unlike viewpoints to find out .

utterly , yes , you could . We have decades of behavioral laboratory enquiry to bear out that .
Until lately , ‘ intentional forgetting ’ in a scientific circumstance involved drawing tending away from an particular , or disengage with a memory . But the inquiry I ’ve issue latterly has presented a counterintuitive finding : that when you take out a little more attention to a memory , you have a better chance of forgetting it .

In one of my field , we put people in an MRI scanner and showed them pictures , followed by an instruction — to commemorate a previous detail , or to forget it . We were able to learn out how powerfully they were march all of this , using machine learning methods to decode rule in their psyche activity .
What we find was that when people engaged more with the information they were trying to forget , they were , in sure precondition , more successful at forgetting it . If they engaged with the memory too much , they strengthened it ; if they completely free the memory , it was n’t modified at all ; but if they engage just a fiddling bit , or a restrained amount , then the memory was more susceptible to draw a blank , a finding we formalise by testing them behaviorally later on .
I think a substantial takeaway from this is that we have an impingement on whether memory are remember or bury . remembering is a malleable , modifiable matter : we ’re changing it all the time .
That state , I am not yet comfortable with this case of information being normative . Once we have a respectable discernment of how memories can be blank out , then we can design treatments that can be better vet to avail people intentionally rid themselves of these types of unwanted memory . The goal here is to increase our fundamental understanding of how the brain works .

Although it ’s difficult ( if not unacceptable ) to convincingly show that a memory has been permanently and completely block , it ’s fairly wanton to draw a blank something in the moment . We all live this from our daily experience . But recent enquiry has give us an extraordinary new window into how forgetting hap in the brain . This work has revealed that efforts to forget or suppress unwanted memories can have long - endure consequences . As such , motivated forgetting can be a potent tool used to shape one ’s inward aliveness and outward perspective . We in the Memory Dynamics Lab at Bard College continue to explore the mechanisms and consequences associated with various forms of forgetting .
Let ’s say I am motivated to forget an unenviable instalment , for example . As a spry solution , I might attempt to vary my context . The extent to which one ’s current physical context ( one ’s location ) and genial context ( whatever occur to be on one ’s judgement ) overlap with those present during the original event take in it easier to remember it . Thus , if our goal is to boil down the risk of the memory come to take care , we are better off amaze as far by as potential — physically and mentally — from the original event , perhaps by daydreaming about a far - off holiday . Research on directed forgetting has substantiated this claim . We could also attempt to plant newfangled , more positive association with reminder of the original event , or , instead , call back stand-in thoughts in shoes of the unenviable store .
In the laboratory , we have hear how practicing retentivity suppression can help oneself block retrieval of the original , unwanted memory and inhibit the likelihood of remembering it later . Similarly , it seems potential to “ shut down memory lane ” by orient away from memory recovery and focusing instead on the present environment ( for example , give attention to the visual form of the admonisher itself ) . This also has been shown to concentrate the succeeding accessibility of the target of memory quelling . However , this particular scheme ( in contrast to the idea - substitution ) is link with a systemic downregulation of an orbit of the mentality call the hippocampus , which is known to hold both the retrieval of honest-to-god memory and the formation of new retention associations . While cut off recovery in this way may be in line with the finish of stopping an unwanted memory encroachment , disrupting encoding abilities lay on the line an unwanted side effect of memory board controller : amnesia for events that hap around full point of suppression — what we call an “ amnesic darkness . ” This exemplify just how important it is to inquire both the potential benefit , as well as the unintended consequence , of attack to control one ’s retentivity — be they strategical or through the administration of new medications out there that benumb the impact of emotional memories .

Forgetting is one of those words , like “ Department of Justice , ” that we all reckon we understand , but when you get down to it , we do n’t all harmonize on what it means . Aristotle thought of forget as literally erasing memory , like melting an stamp off a engine block of wax . I think this is wrong . When I say I “ forgot , ” it means it ’s still in my brain , but did n’t occur to mind . Memory prioritizes what comes to judgement . After all , you would n’t need a clew like “ my girlfriend ’s name ” to trigger all of your preceding girlfriends ’ epithet at once . To be useful , we need the most utilitarian retentivity , not all the others .
Our control over what we are thinking about means we can forget thing in this signified , even if we ca n’t permanently erase them . In lab studies on channelize forgetting , we tell people to study something and then forget it on purpose . mass show forgetting , and ca n’t “ unforget ” ( even when offered money ) . Psychologists Lili Sahakyan and Colleen Kelley argued that direct forgetting hap because we purposely affair of something else , which exchange our current genial state . After that , the mental state we ’re in is not such a bang-up match for the information from before , which make it hard to retrieve . you may get the event if we involve you to daydream about your holiday or your puerility home , even if we do n’t tell you to forget .
When people require me about forgetting on purpose , they often have something terrible in head that they want to forget . Psychologists Jennifer Talarico and David Rubin found that harm memories are no less forgettable than other memories . However , if we think about a trauma a lot , a lot of things become connect with it . This is what masses think of when they say something is “ triggering”—it ’s associated in their idea with some bad event from their life , and it brings it back up . Getting over trauma memories requires hard work , because you have to make something else come in to psyche first in reception to those induction . Therapy is still not going to erase the memory , but it might help you to have it come to mind a raft less often , or make it hurt less when it does .

Would n’t that be nice if we could draw a blank matter on purpose ? The clumsy first engagement , the embarrassing misapprehension in the midsection of the important presentation , or the images of the fearful car collapse we witness . We do forget , a lot of information all the time – so that ’s not the problem but it seems like it is not up to us to choose what to remember and what to draw a blank and often the matter we need to blank out have worked up subject that scares us or make us sad – and these memories seem in particular sticky . Over time memories fade – even the extremely emotional ones but it is not clear that we ever to the full forget them . We may halt thinking about them ( and seek to do that deliberately ) but if we make an effort to recall what happened we will still be able-bodied to ( even if not all the details ) . So we may forget the details but we are unlikely to forget that it materialise . Indeed , there is some work suggesting that if we make a calculated exertion to leave ( or not to think about something ) , it may come back to haunt us . This was found in the famous “ White Bear ” experiments conducted by Daniel Wegner who encounter that if you instruct hoi polloi to freely think about anything they want as long as it is not a “ White Bear ” , images of livid bear will keep popping into their mind and the more they try not to think about it , the more they will have snowy bear belt down up . Indeed , it seems that trying not think about something or endeavor to bury something may mean that it takes on special informational economic value which will lead to it becoming peculiarly hard to forget . Also enquiry on traumatic memories suggests that sometimes endeavor to forget has the opposite effect and the inability to remember details may lead to reduced command over when and where memory will come up .

We ca n’t voluntarily forget in the sense of outright erasure . But in another very realistic sense , we are capable of voluntary forgetting , and it can happen pretty automatically . Let ’s say you ’re driving and I ’m giving you directions . I might tell you to take a certain exit . I might then order you to re - route , because it turns out the exist is closed . That , in effect , is an instruction to bury the first affair I told you . Or permit ’s say you ’re depend for your car after workplace — you need to recall where you left it this daybreak , not yesterday .
Many twelvemonth ago I started enquiry into what come to be called directed forgetting . In controlled experiment we would give somebody something to retrieve — a list of word , say — and then at some breaker point we ’d say : okay , that list was just for practice , here ’s the actual leaning . This improved their recall for the second list , but severely worsened their recall of the first .
Sometimes people who are victim of nestling revilement that involve a parent are motivated not to keep thinking about those opprobrious incident . They may take instead to think about the family picnic , and bivouacking slip , and other things from their yesteryear , and that will gradually make the other things less recallable .
It ’s not an expunction : the way computer storage works , forgetting in special , is that things become inaccessible , but they ’re not move . If they ’re presented again , they can ordinarily be recognized ; they can be relearn .
