Week 2 Textbook Chapter 1 Flashcards
What is a principle of the Scientific Method?
Replication: strengthens or weakens findings.
When is a statistic considered “statistically significant”?
When the odds of it occurring are 1 in 20.
Why is science more credible?
Science is empirical and systematic so its has a higher chance of accuracy
What are forms of non-scientific knowledge?
1) appeals to authority,
2) tradition,
3) common sense,
4) legends,
5) myths,
6) personal experience
Non-scientific knowledge: authority?
Experience or expertise leads to claims to knowledge. Often seen as infallible.
Non-scientific knowledge: tradition?
Often we use cumulative knowledge (traditional knowledge) as a springboard to develop new theories.
May lead to provincialism: “tendency to ignore or disparage knowledge and viewpoints from a culture that is not your own.” This is inherent in traditional knowledge.
Non-scientific knowledge: common sense?
“Knowledge based on ordinary reasoning commonly accepted by others in society”
ex: opposites attract
Non-scientific knowledge: legends and myths?
Legends = “Stories that are related to many in a particular group and are accepted as historical and true
Myths = unproven or false collective beliefs used as evidence to justify a story idea or concept
Myth ex: hurricane victims as criminals / forensics is trustworthy and important like in CSI
Non-scientific knowledge: Personal Experience? 4 ways it can mislead us?
1) Overgeneralizations: We are bad at interpreting ourselves and this leads to faulty eyewitness statements
2) Selective observations: may only notice thing that support our current opinion
3) Premature closure: mishaps in logic such as missing evidence, insufficient evidence or faulty conclusions
4) halo effect: when knowledge is created through the overgeneralization of authority figures
What is distinct about scientific knowledge?
1) Prediction and explanation: based on theory
2) Systematic observation and empiricism: using our sense as predicted by theory
3) Scientific Reasoning: using rationality and logic a theory or model is created based on the findings (knowledge)
Transparency: documented process so that it can be replicated
Provisional: the outcome is analyzed for limitations and alternative explanations
What are the limitations of ideologies?
Fixed and closed, appear to have certainty, dismiss contradictory evidence, cannot be proven or improved.
Positive aspects of theories (why do we use them)?
1) welcome modification
2) assumed neutral and consistent
3) Allow for predictions based on set circumstances
4) not contradictory
5) falsifiable, parsimonious
What is parsimony?
Explains with a few principles but doesn’t oversimplify.
“A Parsimonious theory simplifies reality and combines essential elements to promote our understanding of a social phenomenon”
*theories have
Falsifiability?
- Data can be invalidated
- Required for something to be “scientific”
Serendipity?
“An open mind to chance observations that are typically unassociated with the research questions under investigations but lead to new knowledge”
Must be open to unexpected findings.
Definition: Epistemology
A philosophical concept that describes how we know a claim to knowledge is legitimate (process oriented)
acknowledges reality or how we know what we know.
Definiton: Ontology?
Establishes what is deemed to be true (conclusion oriented).
creates a definition of reality.
Goal of Nomothetic Research?
Seeks to develop rules about the norm to explain observable phenomena.
Idiographic research?
Studies individuals to understand properties that differentiate them from others.
