Chapter 1 Flashcards
Tenacity
nonscientific; believe something based on tradition and superstition. limitations: can’t separate accurate from inaccurate or correct erroneous answers
Authority
nonscientific; rely on info or answers from an expert in the field. limitations: even experts get things wrong
Intuition
nonscientific; information accepted on the basis of a hunch. limitations: can’t separate accurate from inaccurate or correct erroneous answers.
rationalism
nonscientific; use logic to derive truths; limitations: only valid if all premises are true
Empiricism
nonscientific; knowledge is derived via direct observation; limitations: observations can be misinterpreted, experiences can be shaped by beliefs, observations can be time consuming and dangerous
Steps of Scientific Method
- Observe a behavior or phenomenon
- Form a hypothesis
- Use your hypothesis to generate a testable, falsifiable prediction
- Make systematic, planned observations, including control group
- Use the observations to support, refute, or refine the original hypothesis
- Communicate results, undergo review by peers
- Make a new hypothesis
Fundamental Assumptions of Science
Science is real, rational, regular, discoverable, and determinable
Real
Objects persist when not observed
Rational
objects are understandable with logical thinking
Regular
laws governing objects of study are consistent across multiple situations
Discoverable
laws can be revealed using achievable means
Determinable
every event has a cause
Idealized Properties of Science
Science is empirical (theories evaluated on basis of evidence derived from structured, systematic observations), public, and objective (not skewed by bias)
Inductive reasoning
bottom up reasoning: generally from a small set of examples to all possible examples
Deductive reasoning
top down: use general statement of all possible examples to describe a small, specific example
