The Neuroscience of New Year’s Resolutions
Rachael Watson

Introduction
Now that January is coming to a close, many of us are reflecting on our New Year’s resolutions. Research has found that around 38–48% of people set goals for the new year, and that the most popular resolutions are improving health, fitness, and finances (Park, 2025; Davis, 2023). Specifically, many people strive to exercise more, eat healthier, lose weight, and save money for the broader goal of self-improvement and long-term well-being (Davis, 2023). However, only 8% of people successfully follow through and make their goals a long-term habit (Park, 2025). But why is this discrepancy so high? The answer may surprise you, and it’s all to do with neuroscience!

The science of forming new habits
Brains are wired to avoid uncertainty and conserve energy, which leads to the formation of habits and predictable routines (Bar, 2007). Over time, as we repeat a behavior, our neural pathways are strengthened. This allows the brain to rely on automatic processing, which refers to the unconscious, effortless, and rapid handling of information with minimal attention or cognitive effort (McLeod, 2023). As a result, when we attempt to change an established pattern of thinking or behavior (i.e., stop a “bad” habit), our brains often resist, perceiving the change as inefficient, uncomfortable, or even threatening. Key brain structures involved in this process include:
Prefrontal cortex: This area is considered the front part of your brain, which is located right behind your forehead. It is responsible for higher-level functions such as decision-making, planning, impulse control, and goal setting (Cleveland Clinic, 2025; Buschman & Miller, 2014).
Basal ganglia: This is a cluster of nuclei found deep in the neocortex of the brain. The basal ganglia is primarily involved in motor control, but is also associated with reward and cognition, and helps to manage habit-memory and routine behaviors (Young et al., 2023; Buschman & Miller, 2014). 
Amygdala: These are small, almond-shaped structures located under each hemisphere (aka side) of the brain (Johns Hopkins Medicine, 2025). As part of your brain's limbic system, the amygdala helps to regulate emotional responses and detects perceived threats. When faced with change or uncertainty, the amygdala may trigger stress or “fight or flight” responses (Maddux et al., 2012; Johns Hopkins Medicine, 2025). 

While the prefrontal cortex pushes for growth and change, the basal ganglia and amygdala prioritize safety, familiarity, and energy conservation. When this internal conflict occurs, the brain often defaults to old habits, emotional reactions, or avoidance, making change feel difficult, overwhelming, or exhausting—even when the change is beneficial.

Cognitive biases: another component 
As mentioned, research describes how emotional responses in the limbic regions of our brain (like the amygdala) interact with cognitions in the prefrontal cortex to shape judgment and decision-making. This interactive push-and-pull between emotional and cognitive systems is the basis of many cognitive biases (Codex, 2023). These biases impact how we respond to the world around us, and can result in irrational judgments shaped by our perceptions, memories, and personal or cultural beliefs (CogniFit, 2025; Ruhl, 2023). When we’re struggling to form new habits, there may be 3 cognitive biases at large:
Status quo bias: this reflects a desire to keep things the way they are, rather than accept change, even if the alternatives might offer better outcomes (Cherry, 2025).
Loss aversion: this happens when the fear of a potential loss is felt more intensely than the joy of an equivalent gain (The Decision Lab, 2025).
Confirmation bias: this is the tendency to favor information that supports existing beliefs or opinions, while giving disproportionately less consideration to alternative possibilities (Ruhl, 2023).
When it comes to forming habits, these confirmation bias can make habit change feel far more difficult than it actually is. Status quo bias keeps us attached to familiar routines, loss aversion exaggerates the risks of trying something new, and confirmation bias reinforces limiting beliefs about ourselves. Yet, recognizing these patterns is the first step to change. By noticing when the brain defaults to old habits, we can intentionally make mindful choices that will gradually rewire behavior, despite resistance from the basal ganglia and amygdala.

How to form habits (without overwhelming your brain)
Forming new habits can feel daunting (no wonder!), but understanding how the brain works can make the process easier and more sustainable. Research highlights strategies that reduce mental resistance and make change more automatic, such as:
Start small and be specific: Trying to overhaul your entire routine at once can trigger stress and increase the likelihood of giving up (Lally et al., 2010). Therefore, start with tiny, achievable actions. For example, instead of “exercise more,” try “walk for 5 minutes after lunch.” Small steps create early wins, strengthening neural pathways that support automatic processing.
Make it rewarding: Positive reinforcement increases the likelihood that a behavior will stick (Schultz, 2015). Even small rewards, like a brief moment of self-acknowledgement, can activate the brain’s dopamine system, encouraging repetition.
Use cues and triggers: Habits are often formed when behaviors are paired with consistent cues (Wood & Neal, 2007). For example, brushing your teeth immediately after breakfast creates a reliable context that signals your brain to act automatically. Consistent cues help basal ganglia encode new routines. 
By starting small, reinforcing behaviors, and using consistent cues, you can form sustainable habits without overwhelming your brain. Understanding the brain’s natural preference for routine, as well as the biases that resist change, allows for smarter, more intentional habit-building.
