Summary: Splashing out on immediate luxuries or saving for a distant, grand holiday? Polishing off an entire bar of chocolate or preserving half for tomorrow? Decisions pitting immediate gratification against long-term, delayed rewards represent a fundamental friction in human psychology. These trade-offs shape everything from personal wealth and career progression to public health compliance and environmental sustainability. Yet, despite their profound impact, the exact psychological underpinnings that govern these choices, and how they diverge across global cultures, remain inadequately mapped.
To resolve this global behavioral puzzle, psychologists mobilized a monumental international research consortium spanning 77 countries. Armed with a target sample size of roughly 15,000 participants across more than 100 collaborating labs, this crowd-sourced, self-funded project represents one of the largest psychological investigations into intertemporal choices ever attempted.
By analyzing how different demographic and cultural cohorts evaluate future monetary rewards, the study aims to uncover the cross-cultural blueprints of human decision-making, offering crucial insights that could refine economic policies, public health messaging, and sustainability initiatives worldwide.
Key Facts
- The Intertemporal Friction: Intertemporal choice defines any cognitive process where an individual weighs immediate, short-term gratification against delayed, long-term consequences.
- The No-Right-Answer Paradigm: Researchers emphasize that opting for immediate rewards is neither objectively “wrong” nor “right.” In resource-scarce or unstable environments, choosing an immediate smaller reward is a rational optimization strategy when future yields are uncertain.
- The Quantifiable Metric: The global study intentionally prioritizes decisions involving monetary rewards, as money provides a highly standardized, easily quantifiable baseline that facilitates flawless mathematical comparison across distinct currencies and economies.
- The Mood Variable: Beyond deep-seated cultural traits, the study tracks volatile situational elements like current mood, noting that individuals seeking immediate emotional comfort are fundamentally predisposed to select near-term gratification.
- A Grassroots Global Network: Bypassing traditional, bureaucratic third-party funding channels, the study is entirely financed and operated by the internal budgets and resource pools of the 100+ participating international research labs.
- A Call for Global Voices: To build a truly representative model of the human mind, the coordinators are actively encouraging adults from all cultural, socioeconomic, and linguistic backgrounds to complete the brief, multi-language online questionnaire before the August 18, 2026 deadline.

Splashing out – or saving for a big holiday? Relaxing on the couch – or working out? Polishing off a whole bar of chocolate – or leaving some for later?
Decisions such as these are not easy to make because the urge for immediate gratification has to take a back seat to a longer-term desire. People’s behavior is highly individual here, and there also appear to be differences between cultures.
To better understand these types of decisions, psychologists from the University of Bonn are working with researchers in 77 countries to conduct an unusually large online study: Around 15,000 people are set to be surveyed.
“Save for a rainy day!” Who hasn’t ever been irritated by this admittedly sensible but rather fun-sapping saying? Whenever we weigh up short-term and long-term consequences against each other, we are making what are known as ‘intertemporal choices.’
“They shape our everyday lives,” says study coordinator Dr. Kristof Keidel from the Department of Psychology at the University of Bonn. The tendency towards immediate consumption has even been immortalized in the rock anthem ‘I want it all, I want it now.’ In many cases, however, greater advantages only become apparent after a longer period of time. Intertemporal choices, and the sacrifice that accompanies them, are a basis for major purchases, health, and sustainability.
Neither ‘wrong’ nor ‘right’
“There are no right or wrong decisions here,” stresses Keidel. “It is solely about personal preferences, which are naturally also influenced by the situation.” When resources are limited, it can even be better to choose the smaller reward straight away – because it is not clear whether there will be anything left tomorrow. Moreover, such decisions often also depend on the person’s mood: Those seeking comfort are more likely to opt for immediate consumption than those who take an optimistic view of the future.
However, aside from individual preferences, findings from previous studies indicate that intertemporal decision-making behavior can also differ between countries. “We want to find out what makes us humans tick and how we can help ensure decisions can be made as well as possible,” says Keidel. The researchers would thus like to expand the pool of respondents as far as possible and cover different cultural backgrounds within the study.
Monetary rewards
The study focuses on decisions concerning money. “They are particularly easy to compare and quantify,” Keidel explains. The results allow conclusions to be drawn on how people in different countries assess future monetary rewards and what effects this has.
“This project is one of the largest ever studies into intertemporal choice – in terms of both the sample size and the number of countries,” says Prof. Dr. Ulrich Ettinger, who coordinates the study together with Dr. Kristof Keidel. More than 100 researchers are collaborating in this project and coordinating the survey in 77 different countries (https://www.psychologie.uni-bonn.de/en/department/departments/cognitive-psychology-i/tricc-project). The study is not financed using third-party funding, but funded by the research groups involved.
The survey only takes a few minutes. Adults can take part in the survey online: https://www.soscisurvey.de/tricc-project/. Participants will ensure their perspective is represented so that decision-making behavior around the world can be better understood from a scientific viewpoint – while also contributing to the success of this major international study. The results are set to be published in a scientific journal and made freely available to the public.
Key Questions Answered:
A: An intertemporal choice is any decision where you have to balance a small reward right now against a much larger benefit that will only arrive in the future. Our brains find these choices incredibly taxing because of an evolutionary tug-of-war. Deep within our minds, older survival networks push us to “grab it now” because, historically, resources were scarce and tomorrow was never guaranteed. To resist that urge and wait for a bigger reward, your prefrontal cortex has to work overtime to apply cognitive brakes and simulate a future that doesn’t exist yet, making self-restraint a highly demanding mental workout.
A: Absolutely not. The University of Bonn team explicitly stresses that there are no “right” or “wrong” profiles in this study. Choosing an immediate smaller reward can actually be the smartest, most logical decision depending on your situation. If you live in an unstable economy with skyrocketing inflation, or if you are in a precarious financial state where resources are highly limited, waiting for a future reward is a massive gamble. In those contexts, secure consumption today is far more rational than trusting a tomorrow that might never deliver.
A: Historically, a massive portion of psychological and economic theories were built on data gathered almost entirely from “WEIRD” populations (Western, Educated, Industrialized, Rich, and Democratic). This created a biased, incomplete picture of human nature. By deploying a massive, self-funded grid across 77 nations, the TRICC project can finally untangle how macro factors—like local cultural traditions, national financial stability, social safety nets, and language structures—shape human impulsivity and patience. It transforms the science of choice from a narrow Western perspective into a truly global map of human behavior.
