Methods of getting knowledge
Intuition – the act/process of coming to direct knowledge/certainty w/out reasoning or inferring
- knowing w/out reasoning
- Used in forming hypotheses
- Problem – no mechanisms for separating accurate form inaccurate knowledge
- Forming hypotheses
Authority – acceptance of info/facts stated by another because they are respected
- facts stated from respected source
- expert whose facts + info r subject 2 testing using scientific process
- Used in design stage of study
- Used when interpreting data
- Problem – authority can b wrong
Rationalism – knowledge from reasoning (correct process)
- Used to derive hypotheses
- To identify outcomes that would indicate truth/falsity of hypotheses
- Rene Descartes
- Problem – rely solely on this can lead to 2 ppl reaching diff conclusions
- Insufficient by self
Empiricism – knowledge from experience
- Observation used to collect data in science
- Facts that concur w/ experience accepted. Those that do not = rejected
- John Locke – tabula rasa
- David Hume
- Problem – research bias. Must be under controlled conditions.
Systematic strategies must b used to reduce researcher bias + maximise objectivity. Naïve
Empericism. Mem of events not constant.

Abduction

Inference to best explanation

What explanation fits observed data best?
- Researchers relying on sample to represent
Crime scene

- Find empty care in driveway
- May be wrong
- Blood splattered there
- My friend who is left handed uses left handed
- Broken window

left handed scissors. Scientific methods
Deduction – general to specific reasoning

- All dolphins are mammals. All mammals have 1. Thomas Kuhn
kidneys. Thus, all dolphins have kidneys. - Paradigm – framework of thought/belief

Criticism of Hypothesis testing ▪ argued there is no such thing as method
- Popper + his falsification position. He said of science, but
the typical manner of justifying the science has many methods
hypothesis by observing facts cannot work. ▪ advocated that science does not give

Holding constant/eliminating influence of
Basic assumptions underlying extraneous variables
scientific research Allows unambiguous claims about cause + effect
Experiments = preferred research method when
Uniformity/ regularity in nature you need to address issue of cause + effect
- Determinism = belief there r Placebo effect = improvement due to
causes/determinants of mental participants’ expectations for improvement,
processes + behaviour rather than the actual treatment
- mental processes fully caused by prior Operationism
natural factors representing constructs by specific set of
- Probabilistic causes = causes that operations
produce outcomes = weaker form of NB for empirical research
determinism that indicated regularities operational definition = defining a concept by
that usually occur the operations used to represent or measure it
- Realism = depth, not regularity objections to operational definition
Reality in nature demands too strict
- Assumption that things we see, hear, single operational definition could not
feel, smell, taste = real completely specify meaning of a term -> leads to
