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
Unstructured (naturalistic observation)
Structured (lab observation)
Self-report measures
Open vs. closed-ended questions
Likert scale

room for diversity within responses
