Intro: fact and fiction What is science? What Science is not Stereotypes Myths Assumptions of science Empricism Determinism parsimony Methods of Science Objectivity control Operational definition Overview
Credibility is good but… • It does not insure “truth.” • SCIENCE!..in the pursuit of truth!
Does Science Equal Truth? • Jose Delgado
How do most Humans make their decisions about truth? • Tenacity • Authority • Intuition • Logic and rationalism
Most of us have difficulties seeing errors in our thinking • “THE AXIOMS OF HUMAN BELIEF”
Humans believe • Humans believe their belief is correct
AXIOMS • When Challenged?
How gullible are we? • Did Clinton Inhale? • Does nicotine cause addiction?
AXIOMS • Humans jump to conclusions.
Axioms • Simplify complex situations
Axioms • Resist deep consideration
Axioms • Vulnerable to perceptual and social illusion
Axioms • Infinite capacity to be….
Axioms • Difficulty identifying our own misconceptions. • So What can we do?
Recognize the problems • We will not be able to approach truth without recognition of our limitations • Devise mechanisms that help reduce these problems.
SCIENCE • What is Science? • Science is NOT….
So what is Science? • METHOD! • A set of principles of observation, measurement and control that seek to uncover objective reality. • “Self-correcting”
Assumptions of science • Truth will be revealed over time with the Scientific Method • Empiricism-consensual validation • Determinism • parsimony
Overview of the Methods of Science • Objectivity • control • Operational definition • Probabilistic thinking • Amorality
Goals of Science • Practicality • Describe • Predict • Understand • Control
THE PROCESS OF SCIENCE • Ideas • Problem Formation • Goal or Hypothesis • Design • Conduct/Collect • Analysis • Interpretation • Report • FEEDBACK
IDEAS • Common observation • Logic • Practical problems • Intuition • Theory
IDEAS cont’ • Theory • Explains • Simplifies • Unifies • interesting • Testable/falsifiable
Theory vs Observational approaches • Deductive vs inductive reasoning • Not truly separable • Popular emphasis on deduction • But…. • Descriptive vs Inferential (experimental) Research
Descriptive vs Experimental Research • Describing vs identifying causes • Consider reactivity and “control.”
Descriptive Research • Poor or Less rigorous approaches: • Anecdotal observation • Case study • Systematic exploration
Better approaches • Archival research • Where could we find meaningful records?
Naturalistic observation • Naturalistic means unobtrusive • Technology • Distance observation • Concealment • Acclimatization/fade
Naturalistic observation with Intervention • A standardized “naturalistic” event
THE PROCESS OF SCIENCE • Ideas • Problem Formation • Goal or Hypothesis • Design • Conduct/Collect • Analysis • Interpretation • Report • FEEDBACK
Which technique would you choose to study…say • Human sexual intimacy?
Psychological Phenomena that are: • Private • Sensitive • Rare • internal
SELF-REPORT approaches…….SURVEYS • What do we want to know • Construction • Questions • responses • Who do we want to know about -Administration • sampling
