Chapter 12
Habits and Addictions
Habits are automatic behaviors learned
through repetition and reinforcement. The habit formation process operates
something like this: We get an external cue, we act, we get rewarded. Rinse and
repeat enough times, and it becomes a habit. Neuroscientists point out the role
of the basal ganglia in habit formation. This can be a beneficial process that
frees our conscious brain to attend to other matters. It is energy efficient.
Unless, of course, the habit becomes compulsive and maladaptive. Refer to the table
below for examples of healthy habits, bad habits, and addictions.
When bad habits become compulsions,
they hijack our brain’s reward systems (the mesolimbic dopamine pathway, which links the ventral tegmental area (VTA) and the nucleus accumbens) and can
lead to harmful consequences. Unlike habits, which can often be modified with
conscious effort, addictions resist change due to neurological alterations,
psychological dependence, and environmental reinforcement. Healthy habits often
lead to healthy outcomes for individuals. Addictions are quite the opposite.
They tend to lead to loss of autonomy and well-being.
In summary, both habits and addictions
are shaped by neurological processes, psychological reinforcement, and social
influences. Treatment (which we will cover in Chapter 61) for both undesirable
habits and addictions responds best to early intervention, supportive
environments, and adaptive coping strategies. Examples of successful outcomes
for the afflicted are legion.
Is there such a thing as a healthy
addiction? You may have heard someone claim to be “addicted” to exercise.
Sounds good, right? Actually, no. Addiction is a compulsive behavior that
continues despite harmful consequences. Excessive exercise often leads to
injury. By definition, addictions are unhealthy.
Here are some other examples of healthy
habits, bad habits, and addictions.

Before we cover addiction survival
techniques (Chapter 61), we should briefly discuss risks. If you are familiar
with the dangers of addiction, you are welcome to skip to the next chapter. If
not, hold on to your shoe.
Risks
Addictions carry significant personal
risks that affect nearly every area of life. These risks depend on the type of
addiction (substance vs. behavioral), but many overlap. Here’s a breakdown:
Addiction Types
Substance addictions:
- Organ damage (e.g., liver disease from alcohol, lung damage from
smoking).
- Increased risk of heart disease, cancer, infections (especially with
IV drug use).
- Sleep disturbances, appetite changes, and weakened immune function.
Behavioral addictions (gambling,
gaming, etc.):
- Sedentary lifestyle → obesity, cardiovascular problems.
- Sleep deprivation from compulsive use.
- Stress-related conditions (headaches, hypertension).
Addiction Risks
- Chronic anxiety, guilt, or shame about the behavior.
- Higher rates of depression and suicidal thoughts.
- Loss of impulse control and emotional regulation.
- Escalating tolerance → compulsive pursuit of stronger “highs” or
stimulation.
Cognitive and Behavioral Risks
- Poor concentration and memory problems.
- Impaired judgment and decision-making.
- Increased risk-taking (unsafe sex, reckless spending, dangerous
driving).
- Neglect of responsibilities at work, school, or home.
Social and Relationship Risks
- Erosion of trust with friends, partners, or family.
- Social isolation or withdrawal from healthy relationships.
- Conflict, dishonesty, and secrecy around addictive behavior.
- Risk of domestic violence or neglect in family settings.
Financial and Legal Risks
- Financial instability (money spent on substances, gambling, or
compulsive shopping).
- Job loss due to absenteeism, reduced performance, or workplace
accidents.
- Legal consequences (DUIs, possession charges, fraud, theft).
- Debt, bankruptcy, or homelessness in severe cases.
Loss of Identity and Purpose
- Life becomes centered around the addiction rather than values,
goals, or relationships.
- Diminished self-esteem and sense of agency.
- Difficulty imagining life without the addictive behavior.
The personal risks of addiction are
comprehensive: they damage the body, mind, relationships, finances, and sense
of self. Unlike bad habits, addictions are progressive disorders that tend to
worsen without treatment. But with support, many people recover and rebuild
healthier, more fulfilling lives.
Now let’s delve into the Human Nature
characteristic of cognitive bias, which serves as both a blessing and a curse.
