 Critical Thinking

 "Unscientific" thinking = dangerous



o Belief bias

 We go into a situation with some kind of pre-obtained

understanding/thinking of how it works, and we need to distance ourselves

from that

 Science nowadays fights against this

o Inaccurate assumptions

 E.g. swine flu- connecting that term to the disease hurt the pork industry

o Deception

 People presenting research may not have the best purpose in mind

 Human nature requires that we will fall for things if they're pitched in the

right way

 Research methods



o Descriptive

 Researchers observe and record participants' behaviors, often forming

hypotheses that are later tested more systematically

 A good starting point when trying to understand a phenomenon and first

start building a hypothesis

 Case studies



 E.g. Little Albert

 Can be intensive and costly

 Limited generalizability

 Observational



 Unstructured (naturalistic observation)

 Structured (lab observation)

 Surveys



 Self-report measures



 Open vs. closed-ended questions

 Likert scale



 Answer 1-7; still closed-ended, but there is more

room for diversity within responses

 Low cost
