Summary: Spend now or save for later? Indulge in a treat today or put it aside for tomorrow? Choices that pit immediate pleasure against larger, delayed rewards are a central tension in human behavior. These trade-offs influence personal finances, career decisions, public health compliance, and environmental choices. Despite their broad impact, the psychological mechanisms driving such decisions—and the ways they differ across cultures—are still not fully mapped.
To address this global puzzle, psychologists organized a large international research collaboration spanning 77 countries. With a target of roughly 15,000 participants recruited through more than 100 collaborating laboratories, this self-funded, crowd-sourced effort is one of the largest investigations into intertemporal choice ever conducted.
By examining how people from diverse cultural and demographic backgrounds value future monetary rewards, the study aims to reveal cross-cultural patterns in decision-making. These insights could help shape better economic policy, public health messaging, and sustainability strategies around the world.
Key Facts
- The Intertemporal Friction: An intertemporal choice occurs whenever people balance immediate gratification against a delayed, often larger benefit.
- No Single Correct Answer: Choosing immediate rewards is not inherently “wrong.” In unstable or resource-poor settings, taking a smaller reward now can be a rational response when the future is uncertain.
- Monetary Measures: The study focuses on monetary rewards because money provides a standardized, quantifiable baseline that enables consistent comparison across currencies and economies.
- Mood and Situation Matter: Beyond cultural tendencies, transient factors like current mood affect choices—people seeking comfort are more likely to prefer immediate consumption.
- Grassroots Funding: The project is funded and operated by the participating research teams rather than relying on external third-party grants.
- Building Global Representation: Coordinators invite adults from diverse cultural, socioeconomic, and linguistic backgrounds to complete the brief, multi-language online questionnaire before the stated deadline to ensure the sample reflects global diversity.

Buy the ticket now or save for a grander trip later? Skip the workout and relax on the couch or stick with a fitness routine? Eat the entire chocolate bar tonight or leave some for tomorrow?
Decisions like these are difficult because they require subordinating an immediate urge to a longer-term goal. People vary widely in how they make these choices, and cultural differences appear to influence preferences as well.
To understand these patterns more clearly, researchers at the University of Bonn are collaborating with teams in 77 countries to run an unusually large online survey involving around 15,000 respondents.
“Intertemporal choices shape everyday life,” says study coordinator Dr. Kristof Keidel from the Department of Psychology at the University of Bonn. While pop culture celebrates instant desire, many advantages accrue only after a delay. These decisions and the sacrifices they entail underpin major financial choices, health behaviors, and long-term sustainability.
Context Matters
“There are no universally ‘right’ or ‘wrong’ answers here,” Keidel emphasizes. Preferences reflect personal circumstances and situational constraints. When resources are scarce, it can make perfect sense to choose a smaller, immediate reward rather than risk a future payoff that might not materialize. Mood also plays a role: individuals seeking immediate emotional relief often prefer near-term benefits, while those with a more optimistic outlook may be willing to wait.
Previous research has suggested that patterns of intertemporal choice vary across countries. “We want to learn what drives human decision-making and how to support better choices,” Keidel explains. To do that, the study aims to gather responses from a wide range of cultural backgrounds.
Why Money?
The investigators chose monetary trade-offs because money is straightforward to quantify and compare internationally. Analyzing how people in different countries value delayed monetary rewards enables researchers to draw robust conclusions about cultural and economic influences on patience and impulsivity.
“This project ranks among the largest studies of intertemporal choice in terms of both size and geographic scope,” notes Prof. Dr. Ulrich Ettinger, who co-coordinates the project. Over 100 researchers are involved, coordinating data collection across the 77 participating countries. The initiative is supported by the participating labs’ internal resources rather than by external grants.
Participation takes only a few minutes. Adults are encouraged to complete the brief multi-language survey by the stated deadline to help ensure their perspectives are represented. The research team plans to publish results in a scientific journal and make the findings publicly accessible.
Key Questions Answered:
A: An intertemporal choice is any decision that asks you to trade a smaller immediate reward for a larger delayed one. Such choices are difficult because they require overriding instinctive impulses shaped by evolutionary pressures—ancient survival systems bias us toward immediate gains when the future is uncertain. Waiting requires cognitive control from the prefrontal cortex to simulate future outcomes and suppress short-term urges, making patience a mentally effortful process.
A: Not at all. The research team stresses there is no universal benchmark for “good” versus “bad” choices in this domain. Opting for immediate consumption can be rational in environments with economic instability, high inflation, or limited personal resources—contexts in which waiting may be risky or infeasible. In such situations, securing present needs can be both practical and adaptive.
A: Much psychological and economic research has historically relied on data from a narrow subset of the global population, producing a biased view of human behavior. By obtaining a large, geographically diverse sample, the study aims to reveal how macro-level factors—cultural norms, economic stability, welfare systems, and language—shape impatience and delay tolerance, moving research away from a limited regional perspective toward a global understanding.
