Normative Science Definition and Examples
- Interprets info with preference for a specific policy
- Inherently biased
- “Advocacy science”
- Examples:
○ Pristine ecosystem preferred to human altered ones
○ Native species are better
○ Higher biodiversity is preferable to lower
Descriptive Science
Purely facts and measurements
Deductive Reasoning
- Theory first then experimentation
- Basic sciences (chemistry, physics)
Inductive Reasoning
- Experiments before theory/hypothesis
- Applied sciences (con bio)
- Observation causes ideas
Multiple Working Hypothesis
- Chamberlain 1890
- Distributes effort and reduces ownership of ideas to objectively evaluate hypothesis
Define Axioms
what we know to be true from earlier research
Define Postulate
asserts relationships between set concepts
