2027 Psychologist vs. Criminologist: Explaining the Difference
Co-Founder and Chief Data Scientist
Choosing between psychology and criminology is not just a choice between two subjects that study human behavior. It is a choice between helping individuals understand and change their thoughts, emotions, and behavior, or studying crime, criminal justice systems, and public safety at a broader social level.
Psychologists typically focus on assessment, diagnosis, therapy, research, and behavior change. Criminologists focus on why crime happens, how crime patterns develop, and which policies or interventions may reduce harm. The overlap is real, especially in forensic psychology and criminal psychology, but the training, licensing rules, daily work, and career outcomes can be very different.
This guide compares psychologists and criminologists across duties, skills, salary, job outlook, career progression, stress, and transition options. It is designed for students, career changers, and working professionals who want a practical way to decide which path fits their interests, education timeline, and long-term goals. The U.S. Bureau of Labor Statistics projects a 14% growth in Psychology jobs by 2031, making it especially important to understand where psychology-related careers are expanding and where criminology roles may require a more targeted strategy.
Key Points About Pursuing a Career as a Psychologist vs a Criminologist
- Psychologists typically earn between $70,000 and $120,000 annually, with a 3% job growth rate, focusing on mental health and patient wellbeing.
- Criminologists earn around $60,000, with job growth near 5%, analyzing crime patterns to influence policy and public safety efforts.
- Psychologists impact individual behavior and therapy, while criminologists contribute to criminal justice research and law enforcement strategies.
What does a Psychologist do?
A psychologist studies mental processes, emotions, behavior, and the factors that influence how people think and act. Depending on their specialty, psychologists may provide therapy, conduct psychological testing, design research studies, consult with organizations, support schools, or evaluate individuals involved in legal cases.
In clinical and counseling roles, psychologists commonly assess symptoms, diagnose mental health conditions, create treatment plans, provide psychotherapy, and document client progress. In school psychology, they may evaluate learning or behavioral concerns and help design interventions. In industrial-organizational psychology, they may study workplace behavior, employee performance, leadership, or hiring systems. In forensic psychology, they may assess competency, risk, trauma, or other questions relevant to courts and correctional systems.
Psychologists work in private practices, hospitals, community health organizations, schools, universities, government agencies, correctional settings, research centers, and corporate environments. The role often requires strong ethical judgment because psychologists handle sensitive information and may make recommendations that affect health care, education, employment, or legal outcomes.
In the United States, the median yearly income for psychologists was approximately $112,000 as of 2025. Actual earnings depend heavily on specialty, licensure, degree level, setting, location, and whether the psychologist works in private practice, health care, education, government, or research.
What does a Criminologist do?
A criminologist studies crime as a social, behavioral, and institutional problem. Instead of treating individual clients, criminologists usually examine crime patterns, criminal behavior, justice policies, policing practices, corrections, victimization, and prevention strategies.
The work often involves collecting and interpreting crime data, identifying trends, reviewing case records, interviewing justice-system stakeholders, preparing reports, and evaluating whether programs reduce reoffending or improve public safety. Some criminologists focus on research and policy, while others support law enforcement, corrections, courts, community programs, or nonprofit advocacy.
Criminologists may work in universities, government agencies, research organizations, police departments, correctional institutions, consulting firms, think tanks, or public policy offices. Some roles are desk-based and data-heavy; others involve field research, interviews, program evaluation, or collaboration with law enforcement and community organizations.
Annual earnings for criminologists generally range between $40,000 and $70,000, depending on sector, education, experience, location, and whether the role is in research, government, law enforcement support, consulting, or academia. Higher-paying positions often require graduate training, specialized data skills, or leadership experience.
What skills do you need to become a Psychologist vs. a Criminologist?
Psychologists and criminologists both need strong judgment, research ability, and an interest in human behavior. The difference is where those skills are applied. Psychologists usually apply them to individuals, groups, treatment, assessment, or organizations. Criminologists apply them to crime trends, justice systems, public policy, and prevention.
Core skills for psychologists
- Empathy: Psychologists must understand a client’s experience without losing professional boundaries or clinical objectivity.
- Critical thinking: They evaluate symptoms, behavior, test results, history, and context before making recommendations.
- Communication: Effective psychologists listen carefully, explain complex findings clearly, and adapt their language for clients, families, schools, courts, or medical teams.
- Research skills: Many roles require understanding evidence-based treatments, interpreting studies, measuring outcomes, or conducting original research.
- Patience: Progress in therapy, assessment, rehabilitation, or behavior change can be slow and nonlinear.
- Ethical decision-making: Confidentiality, informed consent, documentation, mandated reporting, and conflicts of interest are central to psychology practice.
Core skills for criminologists
- Analytical thinking: Criminologists examine patterns in crime data, demographic information, policy outcomes, and institutional practices.
- Attention to detail: Small errors in reports, coding, evidence summaries, or statistical interpretation can lead to poor conclusions.
- Understanding of law: Criminologists need working knowledge of criminal justice procedures, policing, courts, corrections, and legal constraints.
- Problem-solving: Their recommendations often aim to reduce crime, improve rehabilitation, allocate resources, or evaluate prevention strategies.
- Communication: They must write clear reports and present findings to policymakers, law enforcement, researchers, community leaders, or the public.
- Data literacy: Many criminology roles reward skill in statistics, research design, geographic crime mapping, program evaluation, and database tools.
Skill fit comparison
| Career | Best fit if you enjoy | May be challenging if you dislike |
| Psychologist | Working directly with people, interpreting behavior, supporting mental health, and applying assessment or therapy methods | Long education paths, emotional labor, licensing requirements, and detailed clinical documentation |
| Criminologist | Studying crime patterns, analyzing systems, using data, and influencing justice policy or prevention programs | Statistical work, policy complexity, limited direct control over outcomes, and slower advancement without graduate credentials |
Psychologists generally have higher earning potential than criminologists, especially when they hold doctoral degrees, state licensure, and specialized expertise. Criminology can still lead to stable and meaningful work, but salaries are often tied to government pay scales, research funding, law enforcement structures, academic rank, or policy roles.
Psychologists with doctoral degrees have a median annual salary of approximately $94,310 according to the U.S. Bureau of Labor Statistics. Entry-level psychologists earn between $50,000 and $70,000, while those with specialties like neuropsychology or industrial-organizational psychology often make over $110,000 annually. The top 10% can earn more than $157,000, with clinical psychologists sometimes exceeding $170,150. Private practice, urban markets, advanced specialization, leadership roles, and additional certifications can increase earning potential.
Criminologists working in research, policy, or law enforcement support often start with salaries below $50,000. With experience and advanced degrees, wages can rise to the $80,000-$90,000 range, especially in federal or specialized roles. Six-figure salaries are less common outside leadership, senior research, federal, consulting, or niche analytical positions.
The salary comparison can be confusing because some professionals work at the intersection of psychology and criminal justice. For example, forensic psychologists and criminal psychologists may appear in psychology salary data even though their work relates closely to courts, corrections, or crime. Criminologists, by contrast, are more often classified under social science, criminal justice, research, or policy roles.
| Factor | Psychologist | Criminologist |
| Typical salary pattern | Higher ceiling, especially with doctorate, licensure, specialization, or private practice | More variable, often shaped by public-sector, research, academic, or law enforcement pay structures |
| Early-career earnings | Entry-level psychologists earn between $50,000 and $70,000 | Many roles start below $50,000 |
| Advanced-career earnings | Top 10% can earn more than $157,000; clinical psychologists sometimes exceed $170,150 | Experienced professionals may reach the $80,000-$90,000 range in federal or specialized roles |
| Best way to increase pay | Licensure, specialty training, private practice, leadership, or high-demand settings | Graduate education, data expertise, federal roles, research leadership, or policy specialization |
Students who want a shorter route to advancement may compare carefully structured options such as a fast track program. The right program should still meet accreditation, licensing, and employer requirements; speed alone should not be the deciding factor.
The job outlook is clearer for psychologists than for criminologists because psychology is tracked more directly in federal labor data. Psychologists have a defined occupational category, while criminologists may be counted across social science, criminal justice, research, law enforcement, corrections, public policy, or academic roles.
Job prospects for psychologists are strong, with employment expected to grow 6% from 2024 to 2034, surpassing average occupational growth. Psychologists will see about 12,900 new job openings annually over the next decade, driven by expanding mental health services in schools, hospitals, private practices, and community settings. Specialized areas like substance use and mental health counseling are projected to grow even faster at 16.8%, while psychiatric technician roles could increase by 20%.
Demand for psychologists is supported by broader awareness of mental health, the need for school-based services, aging populations, trauma-informed care, workplace mental health programs, and greater use of psychological assessment in health, education, and legal settings. Clinical psychologists may benefit from ongoing public health efforts and greater insurance coverage, though opportunities still vary by state, specialty, and reimbursement environment.
Criminologists face a more mixed outlook. Opportunities exist in crime analysis, research, public policy, corrections, program evaluation, academia, and justice reform, but openings may be more competitive and less standardized than psychology roles. Federal employment data for criminologists is limited, so students should look beyond broad job titles and examine specific roles such as crime analyst, policy researcher, correctional program evaluator, intelligence analyst, victim services researcher, or criminal justice faculty member.
Criminal psychology remains a growing niche because courts, correctional systems, law enforcement agencies, and legal teams may need professionals who understand both psychology and criminal behavior. Demand for criminal psychologists remains high, largely due to their recognized role in legal proceedings and forensic assessments since the 1960s. However, students should not assume that a criminology degree alone leads directly to licensed psychological practice; licensure requirements are separate.
Career progression in psychology is usually more formal because licensure, supervised experience, and degree requirements shape the path. Criminology progression can be more flexible, but it often depends on experience, graduate education, technical skills, agency promotion systems, and research or policy credentials.
Typical career progression for a psychologist
- Early preparation: Students usually begin with a bachelor’s degree in psychology or a related field. Entry-level work may include research assistant, case manager, behavioral technician, or human services roles.
- Graduate education: Most clinical and specialized psychology careers require a master’s or doctorate, such as a PhD or PsyD. Research, counseling, school, forensic, and industrial-organizational paths may have different degree expectations.
- Supervised experience: Clinical and counseling roles require supervised practice before independent licensure. Requirements vary by state and specialty.
- Licensure and certification: Advancement often requires supervised hours, licensure exams, and, in some specialties, board certification in areas such as forensic or neuropsychology.
- Specialization and leadership: Psychologists may become licensed clinicians, forensic evaluators, professors, research directors, clinical supervisors, consultants, or administrators.
- Senior roles: Experienced professionals may lead clinics, research teams, training programs, or forensic consulting practices, with salaries averaging $91,800 and exceeding $110,000 in some states.
Typical career progression for a criminologist
- Entry-level positions: Many begin with a bachelor’s in criminology, criminal justice, sociology, psychology, or a related field. Early roles may include police, probation, or correctional officers; investigators; research assistants; or data support positions.
- Applied experience: Practical exposure to courts, corrections, policing, victim services, or community programs can help clarify whether the person prefers fieldwork, analysis, policy, or research.
- Mid-career advancement: Promotions may lead to detective, sergeant, analyst, program manager, supervisor, or agency specialist roles, depending on the organization.
- Graduate education: A master’s or PhD can open roles in crime analysis, program evaluation, policy advising, academic research, teaching, consulting, or senior government work.
- Leadership and research: Advanced criminologists may direct justice programs, lead multidisciplinary research teams, shape public policy, or work in think tanks, universities, or government agencies.
Students comparing graduate options should consider cost, accreditation, faculty expertise, internship access, licensure alignment, and employer recognition. Lists such as easiest master degree online programs can be useful starting points, but the “easiest” option is not always the best option for licensure, research training, or competitive career advancement.
Transitioning between psychology and criminology is possible, but the direction of the move matters. A psychologist moving into criminology-related work may be able to build on existing assessment, research, and behavioral expertise. A criminologist moving into psychology usually faces a longer path because licensed psychology practice requires specific graduate education, supervised clinical experience, and state licensure.
Moving from psychology to criminology
A psychologist who wants to work in criminology, forensic psychology, corrections, courts, or criminal justice policy may need additional coursework or experience in criminal justice, law, forensic assessment, policing, corrections, victimology, or legal procedure. Relevant internships, supervised forensic experience, expert-witness training, and work in correctional or court settings can strengthen the transition.
Licensed psychologists must pass the Examination for Professional Practice in Psychology (EPPP) and satisfy state-specific licensure requirements. Those credentials can be valuable in criminal justice settings, but they do not automatically qualify someone for every criminology or forensic role. Employers may still expect knowledge of justice systems, research methods, report writing for legal audiences, and ethical standards specific to forensic work.
Moving from criminology to psychology
A career change from criminologist to psychologist is usually more demanding. Psychologists in the U.S. usually hold at least a master’s degree-often a doctorate-in psychology, along with state licensure. Because many criminologists come from sociology, criminology, or criminal justice backgrounds, they may need substantial psychology prerequisites, graduate clinical training, practicum hours, internship experience, and supervised post-degree practice.
This transition can potentially extend the education and training timeline by 6 to 10 years. Some students explore flexible doctoral pathways, including a doctorate degree no dissertation, but they should verify that any program meets state licensure requirements if their goal is to become a licensed psychologist.
Employment prospects may justify the investment for some students. The Bureau of Labor Statistics predicts 7% job growth for psychologists from 2023 to 2033, which is faster than average. This growth includes forensic psychology, reflecting ongoing demand for professionals who can connect psychological expertise with criminal justice needs.
Both careers can be intellectually rewarding, but neither is easy. Psychologists often face long training timelines, licensing pressure, emotional strain, and responsibility for client welfare. Criminologists often face competitive job markets, complex data, policy limitations, and the frustration of working on problems that do not have simple solutions.
Challenges for a psychologist
- High educational demands: Many advanced roles, especially criminal psychologist and clinical psychologist roles, require doctoral-level education, supervised experience, and licensure.
- Financial investment: Graduate education can be expensive, and students should compare debt, assistantships, internship availability, and expected earnings before committing.
- Emotional toll: Psychologists may work with trauma, severe distress, family conflict, violence, addiction, or court-involved cases.
- Documentation and legal risk: Clinical notes, assessment reports, consent forms, and testimony must be accurate, ethical, and defensible.
- Burnout risk: Heavy caseloads, crisis work, insurance demands, and client trauma can affect mental health if boundaries and supervision are weak.
- Skill development: Psychologists must build advanced writing, public speaking, assessment, treatment-planning, and problem-solving skills for complex, deadline-driven work.
Challenges for a criminologist
- Educational requirements for advancement: Entry-level roles may be available with a bachelor’s degree, but research, policy, academic, and leadership roles often favor graduate credentials.
- Data analysis stress: Criminologists may work with incomplete data, conflicting findings, political pressure, and high-stakes policy questions.
- Limited direct impact: Even strong research may take years to influence policy, funding, policing practices, or correctional programs.
- Competitive roles: Academic, federal, and senior policy positions can be limited and highly selective.
- Exposure to difficult material: Crime data, victimization research, homicide records, abuse cases, and correctional environments can be emotionally difficult even without direct clinical work.
- Slower job growth: Criminologist positions show modest growth projections, which can affect long-term career security and require broader job-search strategies.
Criminal psychologists earned an average salary of $91,813 in July 2025, with higher wages in states like Wyoming and California, reaching over $100,000[3]. Psychology careers show strong expansion, unlike criminology roles, which have a projected 5% growth from 2018 to 2028[7]. Prospective students should weigh the education timeline, licensing requirements, salary range, job market, and emotional demands before choosing a program. Comparing accredited options through resources such as the list of best universities online can help students identify programs that fit their goals and constraints.
Psychology is often more emotionally stressful when the role involves direct clinical care, trauma, crisis intervention, forensic evaluation, or court testimony. Criminology can also be stressful, but the pressure is more likely to come from data accuracy, policy stakes, deadlines, public safety concerns, or exposure to disturbing crime-related material.
Psychologists, especially those in clinical or forensic settings, may work directly with people experiencing severe distress, trauma, violence, addiction, mental illness, or legal conflict. Forensic psychologists may evaluate offenders, victims, families, or defendants, and their conclusions can influence sentencing, custody, competency, treatment, or public safety decisions. The pressure to produce accurate assessments and provide testimony in court can be significant.
Criminologists usually have less direct therapeutic responsibility, but their work can still carry weight. A crime analyst’s findings may influence police deployment. A policy researcher’s evaluation may affect funding. A correctional program evaluator may help determine whether an intervention continues. Academic criminologists may face publication pressure, grant deadlines, and the frustration of seeing evidence ignored in public debates.
Early-career professionals in both fields may experience higher stress because they are still building expertise, professional confidence, and job security. Strong supervision, ethical training, realistic caseloads, peer support, and healthy boundaries are important in both careers.
| Stress factor | Psychologist | Criminologist |
| Emotional exposure | Often high in clinical, counseling, school, and forensic roles | Usually indirect, though crime-related material can still be disturbing |
| Legal pressure | High in forensic evaluations, expert testimony, and mandated reporting | Present in policy, research, law enforcement support, and corrections work |
| Responsibility for individuals | Often direct through assessment, diagnosis, therapy, and safety planning | Usually indirect through research, policy, analysis, or program evaluation |
| Common burnout source | Caseloads, trauma exposure, documentation, and client crisis needs | Deadlines, data limitations, institutional politics, and slow policy change |
Choose psychology if you want to work closely with individuals or groups to understand, assess, and improve mental health or behavior. Choose criminology if you are more interested in crime patterns, justice systems, social causes of crime, policy, research, and prevention.
- Focus area: Psychologists work directly with mental health, behavior, assessment, therapy, and human development. Criminologists study crime patterns, criminal justice systems, social causes, and prevention strategies.
- Education: Psychologists usually need a doctoral degree and state licensure for independent clinical practice. Criminologists often begin with a bachelor’s degree, but advanced research, policy, or academic roles may require a master’s or PhD in criminology, sociology, criminal justice, psychology, or a related field.
- Work settings: Psychologists may work in clinical offices, schools, hospitals, courts, private practice, universities, or organizations. Criminologists may work in research institutions, government agencies, law enforcement support units, corrections, policy organizations, or academia.
- Skills required: Psychologists rely heavily on interpersonal skill, emotional intelligence, assessment, ethics, and communication. Criminologists rely more on analytical thinking, statistical methods, legal knowledge, research design, and policy interpretation.
- Job outlook and salary: Psychologists have steady growth and median wages around $85,330. Criminologist salaries vary widely, often between $50,000 and $90,000.
- Licensure: Psychology practice is tightly regulated, especially for clinical work. Criminology roles are usually less license-driven but may require agency-specific qualifications, security clearance, law enforcement training, or graduate credentials.
- Daily work preference: If you want client interaction and behavior change, psychology is likely a better fit. If you prefer research, data, systems, and policy, criminology may be a stronger match.
A useful decision test is to ask what problem you most want to solve. If you want to help a person manage anxiety, trauma, addiction, learning challenges, or behavior change, psychology aligns more closely. If you want to understand why crime rises in one neighborhood, whether a rehabilitation program works, or how justice policy affects communities, criminology is the better match.
Students interested in both areas can explore forensic psychology, criminal psychology, victimology, correctional psychology, or criminal justice research. They may also compare best dual degree combinations if they want structured training across psychology, criminology, law, public policy, or social science.
