Summary
We tend to value things more as they become scarce or unavailable. This study models how declining expectations increase subjective value and effort, explaining scarcity and FOMO effects.
Area of Science:
- Cognitive Psychology
- Behavioral Economics
- Decision Science
Background:
- Common observation suggests increased appreciation for items/people when loss is imminent.
- Examples include valuing scarce resources or limited-time opportunities more highly.
Purpose of the Study:
- To investigate the psychological dynamics of why subjective value increases as future availability declines.
- To develop and test a computational model explaining reference-dependent valuation near deadlines.
Main Methods:
- Introduction of a computational model to simulate subjective value changes.
- Analysis of how shifting reference standards and uncertainty affect valuation.
- Examination of effort-based choices in response to diminishing opportunities.
Main Results:
- Model demonstrates increased subjective value as expected future availability decreases near a deadline.
- Simulations show rising subjective value enhances effort to secure opportunities.
- Declining reference points mechanistically explain shifts in value and effort.
Conclusions:
- A declining reference point near deadlines drives increased subjective value and effort.
- This provides a mechanistic explanation for scarcity, FOMO, and related decision-making phenomena.
- The theory offers testable insights into reference-dependent behavior in various contexts.

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Social Exchange Theory
551
As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...

Need for Self-Esteem

The human need for self-esteem has long intrigued psychologists, leading to the development of several theories that explore its evolutionary and functional significance. Among the most influential are the sociometer, hierometer, and terror management theories. Each offers a unique perspective on why people strive for self-worth and how it shapes behavior and social interaction.Sociometer TheoryAccording to sociometer theory, self-esteem functions as an internal gauge of social acceptance. It...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Interference and Decay
509
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
