Can EMDR Create False Memories?

Can EMDR Create False Memories?

Short Answer: Research has not established that Eye Movement Desensitization and Reprocessing (EMDR) therapy routinely creates false memories. However, human memory is not a perfect recording of the past, and researchers have examined whether the eye movements used in EMDR can influence memory accuracy. Some laboratory studies have found an increase in certain types of false recollections, while others have not found the same effect. These findings do not establish that a complete EMDR session creates false memories in everyday clinical practice. EMDR is designed to help people process distressing experiences, not recover hidden memories or determine whether a recollection is historically accurate. If an unexpected memory or unfamiliar detail comes to mind, you can acknowledge it without assuming it is either true or false.

Key Takeaways

• There is no established evidence that standard EMDR therapy routinely creates false memories.
• Human memory is reconstructive, meaning that remembered details are not always perfectly accurate.
• Research on eye movements and false memories has produced mixed findings.
• Changes in a memory's vividness or emotional intensity do not establish whether its details are accurate.
• A new memory or detail appearing during EMDR does not prove that it represents something that happened.
• You do not need to search for forgotten memories, reconstruct missing information, or verify historical events during an EMDR session.

What Is a False Memory?

A false memory is a recollection of an event or detail that did not happen as remembered.

For example, someone might remember a conversation and confidently recall that a particular person was present.

Later, other information may establish that the person was somewhere else.

The recollection may have felt clear and convincing, even though that particular detail was inaccurate.

False memories can involve small details, such as who said something or the order in which events occurred. They can also involve more substantial inaccuracies.

Importantly, an inaccurate recollection is not necessarily a deliberate attempt to misrepresent what happened.

People can sincerely remember details incorrectly.

This is possible because remembering an experience is different from replaying an exact recording of the event.

A memory may contain accurate information while also including details that are incomplete, uncertain, or mistaken.

Why Can Human Memories Be Inaccurate?

Human memory involves reconstructing information from past experiences.

When you remember an event, you may recall certain details clearly while other parts remain less precise.

For example, you might remember feeling embarrassed during a school presentation but have difficulty recalling exactly what the teacher said.

You may remember the overall experience accurately while being uncertain about specific words or actions.

Memories can also be influenced by information encountered afterward.

For example, hearing someone else's description of an event may affect how you later remember certain details.

This does not mean that memories are generally unreliable or that people should doubt everything they remember.

It means that memory accuracy is not determined solely by how clear or convincing a recollection feels.

These characteristics of memory exist independently of EMDR.

What Happens to Memories During EMDR?

During EMDR, you focus on a memory, thought, feeling, or experience while using bilateral stimulation, such as guided eye movements, alternating sounds, or tapping.

The purpose is to work with the thoughts, emotions, beliefs, and physical sensations associated with distressing experiences.

For example, you might begin with a memory of being criticized during an important meeting.

The experience may bring up embarrassment and a belief such as:

"I am not good enough."

As processing continues, your emotional response to the memory may change.

You might still remember the criticism but no longer feel as embarrassed when thinking about it.

You may also develop a more balanced belief:

"One difficult meeting does not define my abilities."

These changes involve how you currently experience and understand the memory.

They do not establish that the historical facts have changed.

EMDR is not intended to rewrite past events or produce new factual information.

Why Have Researchers Studied EMDR and False Memories?

Researchers have investigated whether the eye movements used during EMDR influence not only how a memory feels but also how accurately it is recalled.

Studies have found that recalling an unpleasant memory while performing eye movements can reduce its vividness and emotional intensity.

For example, a memory that initially appears clear and emotionally immediate may later feel less vivid or less upsetting.

Researchers have therefore asked whether changes in memory vividness might also influence the accuracy of remembered details.

Some experiments have examined whether participants remember information that was not originally presented.

Others have investigated whether eye movements affect how people respond to misleading information introduced after an event.

These studies help researchers understand how eye movements may influence memory.

However, a laboratory exercise involving eye movements is not necessarily equivalent to completing a full EMDR treatment session.

That distinction is important when interpreting the findings.

What Does Research Actually Say About EMDR and False Memories?

Research findings have been mixed, and the results require careful interpretation.

A 2022 review published in the journal Memory examined studies of eye movements and false recollections.

The authors concluded that the available research suggested eye movements could increase certain spontaneously generated false memories, but did not reliably increase susceptibility to misleading information.

Spontaneous false memories refer to inaccurate details that people generate without those details necessarily being suggested to them by someone else.

A later review, published in Current Opinion in Psychology in 2026, also discussed evidence suggesting that eye movements may increase some spontaneous false recollections while not necessarily increasing susceptibility to suggestion.

However, other experimental findings have not shown the same effects.

For example, a study published in Behaviour Research and Therapy in 2025 compared EMDR, other memory-focused interventions, and a no-intervention condition.

The study involved 265 healthy adults who completed a laboratory stress task.

Researchers later tested participants' recognition of details from that experience.

They found no significant difference in recognition accuracy between the intervention groups and the group that received no intervention.

These findings suggest that memory accuracy does not necessarily decline after an EMDR-related intervention.

The overall evidence therefore does not support a simple conclusion that EMDR either consistently creates false memories or has no possible effect on memory accuracy.

The important distinction is that findings from laboratory memory experiments cannot automatically be treated as evidence of what happens during complete EMDR therapy.

Research has not demonstrated that standard EMDR therapy routinely produces false memories, and the question continues to be studied.

Is a Memory Becoming Less Vivid the Same as Becoming Inaccurate?

No. Vividness and accuracy are different qualities of a memory.

Vividness describes how clearly or intensely you picture an experience.

Accuracy refers to whether the remembered details correspond to what actually happened.

For example, you might remember an argument clearly but have a less vivid mental image of the room where it occurred.

The image becoming less clear does not automatically mean your recollection of the argument is inaccurate.

Similarly, a memory can remain very vivid while containing an incorrect detail.

During EMDR, some people notice that a memory becomes less emotionally intense or that its image seems less prominent.

That change does not establish that the memory has become more or less accurate.

It describes how the experience currently feels when remembered.

Can EMDR Bring Up Memories That Are Not Accurate?

An unexpected memory or detail may come to mind during EMDR.

However, its appearance does not establish whether it is accurate.

For example, suppose you begin working with a memory of an uncomfortable conversation at work.

During processing, you remember a similar experience from school.

The school memory may feel relevant because both situations involve embarrassment or criticism.

That does not necessarily mean one event caused your reaction to the other.

It also does not establish that every detail of the newly remembered experience is correct.

Memories can become associated through shared emotions, thoughts, situations, or sensations.

You can acknowledge a memory that comes to mind without treating it as a factual discovery.

You also do not need to dismiss it simply because you had not been thinking about it recently.

Can EMDR Recover Hidden or Repressed Memories?

EMDR is not a reliable method for uncovering hidden memories or verifying whether a previously forgotten event occurred.

Sometimes people remember experiences they have not thought about for a long time.

This can happen during EMDR and in ordinary everyday life.

For example, thinking about an old school friend might remind you of a particular classroom or conversation.

The memory may have been absent from your thoughts for years without having been inaccessible or deliberately repressed.

The same general principle applies when another memory comes to mind during EMDR.

An unexpected recollection does not prove that a hidden memory has been recovered.

You do not need to search for memories you cannot currently recall.

EMDR can work with the memories, thoughts, emotions, and sensations that are already available to you.

Can Suggestion Influence How Someone Remembers an Event?

Research on human memory has shown that suggestion can sometimes influence recollection.

For example, repeatedly asking someone to imagine a particular detail or presenting misleading information about an event may influence how that event is later remembered.

This is relevant to many situations involving memory, not only EMDR.

During therapist-guided EMDR, the focus should be on the person's own recollections and experiences rather than encouraging them to produce particular memories or reach predetermined conclusions.

For example, there is a difference between asking:

"What do you notice now?"

and suggesting that a particular event must have happened.

The first question allows the person to describe their current experience.

The second introduces an assumption about the past.

The purpose of EMDR is emotional processing rather than leading someone toward a particular historical explanation.

What If You Remember Something New During EMDR?

If a new memory, image, or detail comes to mind, you do not need to decide immediately what it means.

For example, you might begin a session with a memory of a family disagreement and unexpectedly remember another conversation from years earlier.

You can simply notice what appeared.

A useful approach is to distinguish between what you remember and what remains uncertain.

You might recognize:

"I remember feeling embarrassed during that conversation, but I am not sure exactly what was said."

You do not need to fill in missing words or reconstruct the entire event.

You can also continue working with the emotion or belief connected to the recollection without establishing every factual detail.

If the new memory does not seem relevant to your current focus, you can return to the original experience.

The appearance of another memory does not create an obligation to investigate it.

Does a Strong Emotional Reaction Prove a Memory Is Accurate?

No. Emotional intensity and historical accuracy are different things.

A memory may bring up sadness, embarrassment, anger, or another strong feeling.

That emotional response can be meaningful even when some details of the event remain uncertain.

For example, you might remember a difficult conversation and feel disappointed when thinking about it.

However, the strength of that feeling cannot establish exactly what the other person said or intended.

Likewise, if the memory becomes less emotionally upsetting after EMDR, that change does not mean the original event did not happen.

You can recognize the emotional significance of an experience without using the intensity of the feeling as proof of its accuracy.

What If You Are Unsure Whether a Memory Really Happened?

You do not have to make an immediate judgment.

For example, you might remember a particular interaction but feel uncertain about the timing, the people involved, or the exact sequence of events.

You can acknowledge:

"This is what I remember, but some details are unclear."

That approach does not require you to accept the recollection as completely accurate or reject it as false.

You may also choose to focus on a current thought, emotion, or belief rather than the uncertain historical details.

If establishing what happened is important for a separate personal or practical decision, information such as existing records or other independent evidence may be relevant.

EMDR itself cannot determine whether the memory is historically accurate.

Does EMDR Change the Facts of a Memory?

EMDR cannot change what actually happened in the past.

However, it may change how you remember, interpret, or emotionally experience an event.

For example, someone might begin with a memory connected to the belief:

"Everything was my fault."

As processing continues, they may recognize that other circumstances contributed to the situation.

Their belief might become:

"I was not responsible for everything that happened."

This does not require the event to have changed.

It reflects a different understanding of the experience.

It is also important to recognize that memory recollection itself can be imperfect.

A change in perspective during EMDR does not independently establish whether the person's earlier or later interpretation is historically correct.

The purpose is to work with the emotional response and beliefs associated with the memory, not determine factual truth.

What About False Memories During Self-Guided EMDR?

The same distinction between emotional processing and factual accuracy applies to self-guided EMDR.

Virtual EMDR is a specific structured online program that allows users to complete EMDR sessions independently rather than participating in live therapist-guided sessions.

During a session, you may notice changes in your thoughts, feelings, or recollections.

If an unfamiliar memory or detail comes to mind, you can acknowledge it without assuming it is historically accurate.

You do not need to search for missing information or make the memory more complete.

You can continue working with the feelings associated with what you remember, return to your original focus, or pause the session.

Research on laboratory eye movements and false recollections should not automatically be interpreted as establishing the memory-accuracy effects of a particular self-guided EMDR program.

The practical principle remains the same: EMDR is used to work with how an experience affects you now, not to verify what happened in the past.

How Should You Think About Memory Accuracy After EMDR?

If a memory feels different after EMDR, it can be helpful to separate changes in your emotional response from questions about factual accuracy.

For example, you may notice that:

• The memory feels less upsetting.
• Its visual image is less vivid.
• A negative belief seems less convincing.
• You understand the experience differently.
• A related memory has come to mind.

These observations may be relevant to your EMDR experience.

However, none of them independently establishes that the historical details are accurate or inaccurate.

You can recognize a change in how you feel about a memory without treating that change as evidence about what happened.

Conclusion

Current research does not establish that standard EMDR therapy routinely creates false memories.

Some laboratory experiments suggest that eye movements can influence certain memory errors, while other studies have found no significant reduction in accuracy.

These mixed findings are important, but they do not mean that every EMDR session changes the factual content of memories.

Human memory is naturally reconstructive, and emotional intensity or vividness cannot independently establish whether a recollection is accurate.

EMDR focuses on processing distressing memories and the thoughts, feelings, and beliefs connected to them.

If a new or uncertain memory comes to mind, you do not need to treat it as proof of something that happened or dismiss it as false.

You can work with the experience as you currently remember it without searching for missing information or trying to establish historical facts.

The central distinction is that EMDR is intended to change how distressing memories affect you, not determine whether those memories are historically accurate.
