No way of acquiring new knowledge if ppl constantly dismiss contradictory info
Authority (or relying on authority): believing info from someone of authority or expertise
oProblems
Could be completely wrong
Tendency to give authority to ppl who don't actually have authority (ex. Dr. Oz

Data driven: scientific conclusions supported by data collected
Empiricism: learn info about world thru direct observations
oEmpirical question: answerable thru observations
