Problem 5: science Flashcards
demarcation
boundaries between science and pseudoscience
when is something a pseudoscience
-when it is not scientific
-the main proponents want to create the impression that it is scientific
time bound-demarcation
-science can change over time
-science is heterogeneous
-science itself is not flawless
–> therefore demarcation is difficult
plato jtb
for something to form knowledge it must be: true, be believed and justifiable
3 processes in science
-deduction: general to specific
-induction: specific to general
-abduction: looking at conditions + outcome and concluding that there must be causation (neighbour bought yarn –> he must have a cat)
analytic truth
true by definition (dog is a mammal)
synthetic truth
true because of evidence
truisms
true because it is very obviously true
axioms
part of truism, truth that we do not have to check to know, 2+2 = 4
determinism
all events in the universe have a predetermined cause
scepticism
being sceptic of everything
parsimony
when faced with two or more claims, the one with the fewest unconfirmed properties is seen as the most compelling
falsifiability
to prove something, look for counter evidence, if something is falsifiable, it is not true
truthiness
the degree to which a claim can ‘feel’ true without any good reason to believe it is true
what method does science use to check the quality of the science
peer review, pseudoscience does not use this
