TLDR: This research investigates whether language models (LMs) exhibit and can be manipulated for future- or present-oriented preferences in decision-making. Using time-tradeoff tasks with various contextual prompts, the study found that reasoning-focused models like DeepSeek-Reasoner and Grok-3-mini showed significant adaptability to temporal framing and certain roles (e.g., finance minister) or crisis scenarios. However, LMs generally struggled with personalizing decisions based on geographic or human-like identity differences. The paper introduces “Manipulability of Time Orientation” as a key metric and highlights the need for AI assistants to better understand and align with diverse, long-term human goals for true personalization.
Artificial intelligence is rapidly becoming an integral part of our daily lives, assisting with countless decisions. But how well do these AI systems understand our human tendency to prioritize immediate gratification versus long-term benefits? A recent study delves into this fascinating question, exploring whether language models (LMs) exhibit future- or present-oriented preferences and if these preferences can be systematically influenced.
The research, titled Temporal Preferences in Language Models for Long-Horizon Assistance, was conducted by Ali Mazyaki, Mohammad Naghizadeh, Samaneh Ranjkhah Zonouzaghi, and Hossein Setareh. Their work highlights a critical aspect of responsible AI: ensuring that these systems don’t inadvertently push users towards short-sighted choices or embed hidden biases.
Understanding AI’s Time Orientation
The core of the study involved adapting human experimental protocols to evaluate multiple LMs on ‘time-tradeoff tasks.’ These tasks present choices between a smaller, immediate reward and a larger, delayed reward – a common dilemma humans face. To measure how adaptable LMs are, the researchers introduced a new metric: the ‘Manipulability of Time Orientation.’ This metric quantifies how much an LM’s revealed time preference changes when prompted with future-oriented versus present-oriented instructions.
The experiments used a variety of prompts to simulate different contexts and characters. These included identity prompts (male, female, human, AI), geographic locations (Iran, USA, Europe), crisis scenarios (like a national disaster), and specific legal roles (e.g., a ‘finance minister’). They also directly manipulated the LMs with ‘future-oriented’ or ‘present-oriented’ instructions.
Key Findings: Some Models Show Promise, Others Lag
The study revealed some significant insights. Reasoning-focused models, specifically DeepSeek-Reasoner and Grok-3-mini, demonstrated a notable ability to choose later options when given future-oriented prompts. These models also showed high ‘manipulability,’ meaning they could effectively adjust their preferences based on whether they were instructed to be future- or present-oriented. For instance, in a simulated crisis, these models tended to prioritize immediate rewards, mirroring human behavior under pressure. Conversely, when acting as a ‘finance minister,’ they leaned towards long-term outcomes.
Interestingly, these capable LMs also seemed to internalize a future-orientation for themselves when prompted to act as an ‘AI’ decision-maker. However, their performance wasn’t perfect. A significant limitation observed was their struggle to personalize decisions across different identities (like gender) or geographical locations. This suggests a gap in their ability to detect and adapt to the nuanced socio-political contexts that influence human time preferences.
In contrast, many other LMs, including some from major developers like OpenAI (GPT-4o), Meta AI, Google, and Alibaba, exhibited lower manipulability or even inconsistent performance. Some models gave identical responses across all trials, while others produced scattered, seemingly random answers, indicating a lack of coherent strategy for future-oriented decision-making.

The Path to Truly Personalized AI
The findings underscore that while some LMs show potential in mimicking human-like temporal decision-making, they still lack the deep contextual understanding necessary for true personalization. Human preferences are constantly adjusted based on context, history, and evolving goals – an ability current AI models struggle to replicate.
The researchers emphasize that for AI assistants to be truly effective, they must move beyond ‘one-size-fits-all’ models and be capable of understanding and adapting to diverse human needs and long-term goals. Identifying and mapping diverse human identities, such as gender, age, and geography, is highlighted as a crucial next step, potentially representing a ‘holy grail’ in AI development.
Ultimately, this study marks an important step towards developing AI systems that exhibit ‘intelligence across time.’ Future research will need to explore more facets of human character, integrate real human behavioral data, and investigate multi-turn interactions to build AI assistants that can truly understand, anticipate, and support our evolving long-term aspirations.
