Why are we so attached to our things? - Christian Jarrett

Summary

The video explores why people become attached to their possessions. The feeling of ownership appears very early in life, and it can change how much we value objects, how we think about them, and even how we perform.

Main Ideas

• Ownership increases perceived value. The endowment effect describes our tendency to value something more once it belongs to us—even when we valued it no more than alternatives beforehand.
• Possessions become linked to our sense of self. Brain scans suggest that people respond to objects labeled “mine” with activity in a brain region associated with thinking about themselves.
• We may believe objects have a special essence. Young children often prefer an original toy to an exact copy, as though the original has a quality the copy cannot reproduce. Similar beliefs may help explain the value placed on celebrity-owned objects and family heirlooms.
• Beliefs about ownership can affect perception and performance. In one study, people using a putter said to have belonged to champion golfer Ben Curtis perceived the hole as larger and sank slightly more putts.
• Culture influences attachment. The Hadza of northern Tanzania, described as living in a highly sharing society relatively isolated from modern culture, did not show the endowment effect in a study.
• Attachment can become harmful. In hoarding disorder, an exaggerated feeling of responsibility and protectiveness toward possessions can make discarding items very difficult.
• Digital possessions may change our relationship with ownership. Although some have predicted that physical books and music will disappear, the video suggests physical objects may continue to hold a distinctive appeal.

Studies and Demonstrations

Coffee Mug and Chocolate Choice

• Some students chose between a mug and a Swiss chocolate bar as a reward; choices were split roughly evenly.
• Other students were first given one reward and then offered the chance to swap it for the other.
• Only 11% of those who started with a mug chose to swap it for chocolate. Most who started with chocolate also kept it.
• Lesson: People tended to favor whichever item they already owned.

Brain Activity and “Mine”

• Participants assigned objects to a basket labeled “mine” or one labeled “Alex’s.”
• When they later viewed their newly assigned possessions, brain activity increased in a region commonly active when people think about themselves.
• Lesson: Ownership can become associated with the self at a neural level.

Children and the Copying Machine

• Children aged three to six were led to believe they had built a machine capable of making perfect copies of objects.
• When offered their favorite toy or an apparent duplicate, most chose the original, and many were upset by the prospect of taking home a copy.
• Lesson: People may attribute a unique quality to an original object, a belief that can persist into adulthood.

The Ben Curtis Putter

• Participants were told they were using a putter once owned by champion golfer Ben Curtis; a control group used a standard putter.
• Those given the “celebrity-owned” putter perceived the hole as about a centimeter larger and sank slightly more putts.
• Lesson: The perceived history of an object can influence perception and performance.
