Thinking Critically With Psychological Science

Psychology as a Science

Definition: Psychology is the scientific study of the mind and behavior. Psychologists are actively involved in studying and understanding mental processes, brain functions, and behavior.
Empirical Approach: Psychology employs an evidence-based method that draws on observation and experimentation to explore and understand phenomena without misleading or being misled.
Scientific Attitude: Requires a combination of:
- Curiosity: A passion to explore and understand.
- Skepticism: Questioning accepted ideas and conclusions.
- Humility: An openness to new perspectives and a willingness to revise one's own theories.
Critical Thinking: Involves careful reasoning that does not blindly accept arguments and conclusions. It requires individuals to:
- Examine assumptions.
- Appraise the source of information.
- Discern hidden biases.
- Evaluate evidence.
- Assess conclusions thoroughly.

What Psychology Is Not: Addressing Misconceptions

The Reality of Psychology vs. Public Perception

Many people hold significant misconceptions about psychology, often derived from media portrayals or popular beliefs. Psychology is often not what people initially expect.

Pseudo-psychology

Ideas that lack a scientific basis are termed pseudo-psychology. Examples include:
- Palmistry: Interpreting character or predicting the future by examining lines on the palms of the hands.
- Phrenology: A discredited theory that claimed personality traits could be determined by bumps on the skull.
- Physiognomy: Assessing character or personality from a person's outer appearance, especially the face.

More Than Just Therapy

Psychology delves into far more than just therapeutic practice. While many psychologists do engage in therapy, a significant portion do not.
Approximately one-third of psychologists specialize in areas entirely unrelated to therapy or other helping services.
Even among the two-thirds who expertise in therapy, some focus on teaching, supervising, or researching therapy rather than practicing it directly.

Beyond Mental Disorders

The majority of psychological research focuses on normal processes that occur in everyone, such as how individuals:
- Think
- Learn
- Develop
- Remember
- Speak
- Interact
Contrary to media portrayals (e.g., psychologists helping police track criminals), the field extensively studies everyday human functioning, with only a small portion dedicated exclusively to psychological disorders.

Not Solely Sigmund Freud

While Sigmund Freud was a central figure in psychology for several decades (primarily the early $1900$ s), his dominance is long past.
Currently, fewer than $10\%$ of psychologists practice Freudian psychology.
Freud's influence is not irrelevant, as his ideas and therapeutic approaches shaped many newer treatments, but contemporary psychology is much more diverse, with his voice being one of many.

Distinct from Psychiatry

Psychiatry is a medical specialization focused on the brain and its disorders. The professions are often confused but have critical distinctions:
- Psychiatrists: Are medical doctors ( $MD$ degrees). They complete medical school and perform much of their training alongside other physicians before specializing. Psychiatrists are authorized to prescribe medication (e.g., Zoloft for depression, OCD, panic disorder, PTSD, social anxiety disorder, PMDD).
- Psychologists: Typically hold doctoral degrees (e.g., $PhD$ , $PsyD$ ) but are not medical doctors. They primarily rely on talk therapy and other non-drug strategies to assist clients.
Some individuals with psychological disorders receive integrated care from both psychiatrists (for medication management) and psychologists (for talk therapy).
Current Controversy: Psychologists Prescribing Medication
- A movement began in the $1980$ s advocating for psychologists to gain prescriptive authority with additional training.
- Over time, this movement has gained momentum, leading to legislative debates in many states.
- States that have approved prescriptive authority for psychologists include:
  - New Mexico ( $2002$ )
  - Louisiana ( $2004$ )
  - Illinois ( $2014$ )
  - Iowa ( $2016$ )
  - Idaho ( $2017$ )
- As of now, approximately $160$ psychologists in New Mexico and Louisiana have earned the right to write prescriptions.
- Other states have rejected similar legislation, and the debate continues elsewhere.

Backed by Science, Not Guesswork

Psychology is rigorous and scientific, distinctly separate from unsupported guesswork, unproven opinions, psychics (claiming extrasensory perception, $ESP$ ), or sensationalized TV personalities.
The scientific method is the cornerstone of psychology, transforming speculative ideas into scholarly, evidence-based understanding.
