An external barrier is something outside yourself that gets in the way of achieving your potential. It’s not about what you’re capable of—it’s about obstacles in your environment, circumstances, or society.
External barriers are often harder to overcome than internal barriers because they’re not under your individual control. You can change your own beliefs or learn new skills, but you can’t single-handedly change poverty, discrimination, or lack of access to education. However, external barriers can be addressed—often through community action and systemic change (which is what Level 3 focuses on).
Understanding external barriers is important because they’re often invisible to people who don’t experience them. If you’ve always had access to good education, healthcare, and opportunity, you might not realize how much these things matter. If you face discrimination or poverty, you know firsthand how these barriers limit your options.
Economic barriers limit what you can do based on money: - Poverty makes it hard to afford education, healthcare, housing, or the tools you need to develop skills - Lack of access to credit or capital makes it hard to start a business - High cost of education limits who can attend college or specialized training - Medical debt can trap people in poverty - Example: A talented young person might want to go to university but can’t afford tuition, and their family can’t help. Without money, the door closes.
Educational barriers limit your access to learning: - Poor quality schools in some neighborhoods mean students get less education - Lack of access to technology or internet limits learning opportunities - Limited availability of certain subjects or programs in your area - Language barriers if education is only available in a language you don’t speak - Example: A student in a rural area wants to learn computer programming, but their school doesn’t offer it and they can’t afford private classes.
Healthcare barriers limit your access to medical care: - High cost of healthcare makes it unaffordable - Lack of doctors or hospitals in your area - Discrimination in healthcare (some groups receive worse care or are not believed by doctors) - Lack of mental health services - Example: Someone with a treatable medical condition can’t afford treatment, so their health worsens and they can’t work.
Discrimination and bias limit your opportunities based on who you are: - Racism limits opportunities for people of color in hiring, housing, education, and criminal justice - Sexism limits opportunities for women and girls - Ageism limits opportunities for older and younger people - Discrimination based on disability, sexual orientation, gender identity, religion, or other characteristics - Stereotype threat: when you’re aware of negative stereotypes about your group, it can actually impair your performance—not because the stereotype is true, but because the anxiety and pressure of being judged affects your focus and confidence. - Example of discrimination: Two equally qualified people apply for the same job, but one is rejected because of their race, gender, or other characteristic.
Systemic and institutional barriers are built into how society works: - Criminal justice systems that disproportionately punish certain groups - Hiring practices that favor people with connections or certain backgrounds - Zoning laws that concentrate poverty in certain neighborhoods - Policies that make it hard for people to vote - Structures that favor the wealthy and disadvantage the poor - Example: A person with a criminal record struggles to find employment because many employers won’t hire people with records, even for minor offenses from years ago.
Geographic and environmental barriers limit opportunities based on where you live: - Living in a rural area with limited job opportunities - Living in a neighborhood with high crime and low investment - Living in an area with environmental hazards (pollution, contaminated water, etc.) - Limited access to transportation - Natural disasters or climate impacts that destroy homes and livelihoods - Example: Someone lives in a remote area with no job opportunities, no public transportation, and no way to move because they can’t afford it.
Family and social barriers limit opportunities based on your circumstances: - Being born into poverty - Having family members who are incarcerated or struggling with addiction - Lack of family support or mentorship - Being a caregiver for family members (children, elderly parents, sick relatives) - Social isolation or lack of community - Example: A young person wants to go to college but has to work full-time to support their family, leaving no time for school.
Access barriers limit your ability to participate: - Lack of childcare makes it hard for parents to work or pursue education - Lack of accessible transportation - Lack of accessible buildings or spaces for people with disabilities - Lack of interpreters or accommodations for people who are deaf or hard of hearing - Lack of information about resources or opportunities - Example: A person with a mobility disability can’t access a job because the building has no elevator and no accessible entrance.
External barriers can: - Limit your options: You can’t pursue certain paths because they’re not available to you - Require more effort: You have to work harder than others to achieve the same thing - Create stress and trauma: Discrimination, poverty, and lack of access create emotional and physical stress - Limit your resources: You have less money, time, information, or support than others - Create self-doubt: When you face constant barriers, it’s easy to internalize the message that you’re not capable (which creates psychological barriers on top of external ones)
External barriers are addressed through:
Individual action (limited but important): - Seeking out resources and opportunities that do exist - Building networks and asking for help - Advocating for yourself - Moving to a place with more opportunities (if possible)
Community action (more effective): - Organizing with others who face similar barriers - Mutual aid and support - Collective problem-solving - Building community resources (study groups, mentorship, etc.)
Systemic change (necessary for large-scale impact): - Policy change and advocacy - Institutional reform - Creating new systems and structures that are more equitable - Addressing root causes of barriers (poverty, discrimination, lack of investment, etc.)
The key insight: External barriers are real and significant, but they’re not permanent features of the world. They’re created by humans, which means humans can change them. Individual effort matters, but systemic change is necessary to truly overcome external barriers at scale.
Internal and external barriers often reinforce each other:
Understanding this interaction is important because it shows why overcoming barriers requires both individual work (managing internal barriers) and collective work (addressing external barriers).
Exercise 1: Identifying External Barriers
Think about something you want to do or achieve. Now ask yourself: - Are there economic barriers? (Do I have enough money or access to resources?) - Are there educational barriers? (Do I have access to the knowledge or training I need?) - Are there healthcare barriers? (Do I have access to the health support I need?) - Are there discrimination or bias barriers? (Do I face discrimination based on who I am?) - Are there systemic or institutional barriers? (Are there policies or structures that get in my way?) - Are there geographic or environmental barriers? (Does where I live limit my options?) - Are there family or social barriers? (Do my family circumstances or social situation limit my options?) - Are there access barriers? (Is there physical or informational access to what I need?)
Write down what you discover. You might find one barrier, or several. Remember: identifying barriers isn’t about making excuses—it’s about understanding what you’re working with so you can develop realistic strategies.
Exercise 2: Recognizing External Barriers in Your Community
Look at your community (neighborhood, city, region). What external barriers do you see? Who faces them? What might need to changed to address them?
This exercise is not about blaming yourself for not fixing everything. It’s about developing awareness of how external barriers work and how they affect different people.
Intermediate level would expand with: - Deeper exploration of each barrier type with specific examples - How barriers vary across different groups and communities - Intersectionality: how multiple barriers compound (e.g., being a woman of color facing both sexism and racism) - Case studies of communities that have overcome external barriers - How external barriers affect mental health and wellbeing - The role of privilege in not experiencing certain barriers - How to advocate for yourself and others when facing barriers
Advanced level would include: - Scholarly research on systemic inequality and structural barriers - Historical analysis of how barriers have been created and maintained - Economic analysis of poverty and inequality - Critical examination of policies and institutions that create barriers - Research on discrimination and its effects - Case studies of successful systemic change efforts - How to contribute research and analysis to the program
Topics 4 and 5 have shown you what gets in the way of human potential. Now you understand:
Level 2 teaches you skills to address internal barriers and to begin addressing external barriers on a small scale: - Critical thinking helps you evaluate information and make better decisions - Psychology helps you understand yourself and others - Emotion management helps you work with difficult emotions - Communication helps you connect with others and advocate for yourself - Science helps you understand how the world works and access tools and technology - Education helps you learn what you need to know - Community shows you how to work with others on shared problems - Efficiency helps you use your time and resources wisely
Level 3 teaches you how to address external barriers at scale through systemic change—working with communities and institutions to create lasting solutions.
But first, you need to understand that solutions exist. That’s what the next topic covers.
