Hi, today I would like to share about the interesting topic, namely "Why are established habits difficult to break", the main reason why I choose that topic because the question that I mentioned in the topic touches on the core of the psychology and neuroscience of habits. Habits that have been performed frequently become very difficult to eliminate because they are deeply rooted in three levels: the Brain (Biological), Behavioral Patterns (Psychological), and the Environment.
Here are the main reasons why habits are difficult to break:
🧠 1. Brain Mechanism (Strong Neural Pathways)
Habits are the brain's way of conserving energy. When an action is repeated many times, the brain transforms it from a conscious decision-making process into an automatic response, which involves the following mechanisms:
- Reinforced Neural Pathways (Neuroplasticity): Every time you repeat a habit (e.g., smoking when stressed), the neurons in the brain associated with that action connect more strongly. Imagine it like creating a path in a meadow; the more often it is traversed, the clearer and easier the path becomes.
- Result: The action becomes a default response that is performed without needing to think hard.
- Role of Basal Ganglia: This part of the brain stores habits. When a habit is stored here, the part of the brain responsible for logic and conscious thought (Prefrontal Cortex) no longer needs to work.
- Result: Habits operate subconsciously, making them difficult to "access" and change by sheer willpower.
- Dopamine Effect: Habits that provide quick rewards—such as the feeling of comfort after eating something sweet or relief after procrastinating—release the neurotransmitter dopamine.
- Result: Dopamine creates a strong urge (craving) to repeat the action when a trigger (cue) appears, even if you know the habit is bad.
🔁 2. The Habit Loop
Every habit operates within a three-step cycle that locks in your behavior:
- Cue: The trigger is a signal that tells the brain to enter automatic mode (e.g., seeing a cellphone, 7 PM, feeling bored, or a specific location).
- Routine: The action you take in response to the trigger (e.g., grabbing a snack, opening social media).
- Reward: The benefit or satisfaction you get (e.g., sweetness, feeling entertained, temporary relief).
Difficult to Break Because: This cycle creates an expectation. Once the Cue appears, your brain automatically expects the Reward. If you try to break the Routine, your brain will send strong "need" or "anxiety" signals (craving), demanding that you complete the cycle to get the predicted reward.
🛋️ 3. Psychological and Environmental Factors
- Comfort and Safe Zone: The brain tends to prefer predictability. Old habits feel safe and comfortable, even if they are bad. Change brings uncertainty, which the brain often interprets as danger or stress.
- Self-Identity: If you often repeat a habit, it can become part of who you are ("I am a person who likes to stay up late" or "I am not disciplined"). Changing habits means changing self-identity, which feels psychologically very heavy.
- Environmental Support: An environment that is not supportive or is full of triggers will greatly hinder change. If all your friends smoke, it is very difficult for you to quit because your environment constantly provides Cues and social Routines.
Conclusion:
Habits are difficult to break not because you are weak, but because habits are very efficient automatic pathways created by your brain to conserve energy. To change them, you cannot rely solely on willpower, but must identify and break/replace elements in the Habit Loop (Cue → Routine → Reward) so that the brain can build new neural pathways."
