Psychology says people who can't throw things away may be holding onto more than just objects

Almost everyone has a drawer filled with old chargers, greeting cards, broken gadgets, or clothes they haven't worn in years. Even when these items serve no practical purpose, throwing them away can feel surprisingly difficult.

Psychology says this behavior doesn't automatically mean someone is a hoarder. In fact, many people develop emotional attachments to everyday objects because those possessions become connected to memories, identity, or the feeling of security. Researchers have found that the human brain often places greater value on things we already own than on identical items we don't own.

We value things more simply because they belong to us

One of the strongest explanations comes from the Endowment Effect, identified by Nobel Prize-winning psychologist Daniel Kahneman, economist Richard Thaler, and psychologist Jack Knetsch.


The Endowment Effect suggests that people assign greater value to possessions simply because they own them. For example, an old coffee mug received as a birthday gift may seem worthless to someone else but priceless to its owner because of the memories attached to it. Ownership itself changes how the brain evaluates an object.

Losing something often feels worse than gaining something

The Loss Aversion principle from Prospect Theory, developed by Daniel Kahneman and Amos Tversky, explains that people generally experience the pain of losing something more intensely than the pleasure of gaining something new.

For example, throwing away a ten-year-old jacket may feel emotionally uncomfortable, even if it has not been worn in years. The emotional focus shifts toward what is being lost rather than the extra space being gained. This helps explain why decluttering can feel emotionally exhausting.

Objects often become part of our identity

Psychologist Russell Belk's Extended Self Theory suggests that people often view their possessions as extensions of themselves.

Certain belongings represent:

• Personal achievements
  
• Relationships
  
• Childhood memories
  
• Family traditions
  
• Important life milestones
  

For example, someone may keep an old concert ticket because it reminds them of a meaningful experience rather than because of the paper itself. Discarding the object can sometimes feel like losing part of one's personal history.

Emotional attachment makes letting go difficult

Attachment Theory, first developed by John Bowlby, is usually associated with relationships, but psychologists have also explored how attachment can extend to meaningful possessions. For example, a child may continue keeping a favorite stuffed toy into adulthood because it represents comfort and safety.

Similarly, someone may hold onto a late parent's sweater because it provides emotional connection long after the person is gone. The object becomes emotionally significant beyond its practical use.

The sunk cost effect keeps people holding on

The Sunk Cost Effect describes the tendency to continue valuing something because of the time, money, or effort already invested in it.

Imagine someone who bought an expensive exercise machine that now sits unused in the garage. Instead of donating it, they think: "I spent too much money to get rid of it." Although the investment cannot be recovered, the previous cost continues influencing present decisions.

Hoarding disorder is different

Psychologists emphasize that occasionally keeping sentimental or unused items is common.

Hoarding Disorder, recognized in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), involves persistent difficulty discarding possessions regardless of their actual value, leading to significant clutter and impairment in daily life.

For example, someone with hoarding disorder may be unable to use rooms for their intended purpose because accumulated items block living spaces. Simply keeping old books or childhood souvenirs does not automatically indicate a mental health disorder.

Memories matter more than objects

Research shows that many people fear losing the memories associated with possessions rather than the possessions themselves. For example, a worn-out birthday card from a grandparent may have little financial value but tremendous emotional importance.

Psychologists often encourage people to preserve meaningful memories in ways that don't require keeping every physical object, such as taking photographs or creating memory albums.

Research also reminds us that keeping sentimental belongings is perfectly normal. The key difference lies in whether possessions enrich our memories, or begin interfering with daily living and well-being.

FAQs

Why do people keep things they never use?

Psychologists suggest that emotional attachment, memories, loss aversion, and ownership can make it difficult to discard possessions, even when they no longer serve a practical purpose.

Does keeping old items mean someone has hoarding disorder?

No. Many people keep sentimental belongings without meeting the clinical criteria for hoarding disorder. The diagnosis depends on persistent difficulty discarding items that significantly disrupt daily life.
