Q

why do we not answer questions like scientists in real life?

A

Q

what are ways that confirmation bias can be avoided?

A
  • doing double blind research
  • the experiment administrators have no idea the condition of the subjects,, and they data collectors do not know what they are testing for

Q

what is the definition of pseudoscience?

A

products or theories that are presented as science, but would not hold up in a lab
- it is based in nonscientific science
- it can look like science on the surface
- usually is giving support for a product or idea

Q

what are some features or pseudoscience?

A
  • relies on anecdotal evidence
  • relies on confirmation rather than disconfirmation (only reports the times that it works)
    -avoids scientific review
  • generalizes to all situations

Q

what are ways that people “sell” pseudoscience?

A

-use words like “alternative”, “nontraditional”, and “clinically proven” (buzzwords)
- relies on personal endorsement
- solution for many different problems

17
Q

why do people fall for pseudoscience?

A
  • these products target people who are vulnerable, desperate, or scared
  • sometimes the product tries to make you feel naïve for disagreeing with them
  • also people have a hard time distinguishing between real and junk science
18
Q

what is the difference between junk science and pseudoscience?

A

junk science has evidence to support it, however that evidence is not always reliable

pseudoscience has nothing to back it up

19
Q

what are belief bases?

A

personal beliefs come from upbringing and group consensus

20
Q

why do we tend to stick so deeply into our belief bases?

A

we traditionally ignore contradictory evidence from outside groups
examples: superstitions

21
Q

what is a post-hoc explanation?
(what does science do instead?)

A

when you search for an explanations after something has happened
(science instead forms hypothesis to explain something before it occurs)

example: last night I went to bed with wet hair and today I am sick,, therefore I must have gotten sick because I went to bed with wet hair

22
Q

what is belief persistence?

A

we tend to ignore new information when it conflicts with what we already believe
example: crop circles were though to be caused by supernatural forces, but really there is evidence that people just make them for artistic purposes. However, people still choose to believe that tcrop circles are caused by supernatural forces

23
Q

what is misattribution?

A

the misunderstanding of cause

24
Q

methods of inquiry

A
  1. method of authority
  2. rational method
  3. the scientific method
25
Q

what are examples of methods of authority?

A

books, professors, google, parents, NPR
- good places to start but they are limited
example of limitation) paul hellyer,, the alien Canadian defense minister guy

26
Q

what is the method of authority

A

going to someone or something thought to be an expert in said area or field

27
Q

what is the rational method of inquiry?

A

we use reasoning to come to a conclusion

28
Q

what are some of the limitations of the rational method?

A
  • it only works with accurate and complete info
    example) any conspiracy theory
    ie) - radiation can be dangerous,, 5G towers emit radiation,, therefore 5G is dangerous
  • it is limited by personal bias
    ie) some things seem irrational but are true, like scotlands national animal,, and vice versa some things seem rational but are untrue
29
Q

what is the scientific method of inquiry?

A

a repeatable process of seeking answers with data. it is a powerful approach to gaining knowledge
(everything that science knows comes from this process)

30
Q

what are the 4 steps of the scientific method?

A
  1. observe a phenomenon
  2. form a tentative explanation
  3. experiment/observation
  4. refine and reset
31
Q

step 1 of the scientific method (observe a phenomenon)

A
  • often based on prior research
  • described in terms of variables
    (a variable is a measurable characteristic)
    example: expensive cars drive like jerks
32
Q

step 2 of the scientific method (form a tentative explanation)

A
  • what is the expected relationship between variables?
  • the hypothesis will link the variables
    ex) the more expensive the car the faster they will drive
  • as one variable does x. the other one does y or x
33
Q

step 3 of the scientific method (experiment and observe)

A
  • this is what sets the scientific method apart
  • design a study to observe variables
    ex) observe cars driving and make notes of car models and speeds
34
Q

what is important for the integrity of an experiment?

A

try to isolate any variables other than what you are testing

35
Q

step 4 of the scientific method (refine and retest)

A
  • review your new data
    ex) expensive cars only drive fast IF they are sports cars
  • revise your old hypothesis based on this and observe again
    ex) the more expensive the sports car the faster they drive
36
Q

what are the results of a scientifically sound experiment:

A
  1. rigorously evaluated
  2. empirical
  3. testable
  4. parsimonious
  5. general
  6. tenative
    (note: all of this relies on the honesty of the researcher)
