2. The Scientific Method

3. Do you consider psychology a science?
Do you consider psychology a helpful tool or is relying on past experiences and intuition just as effective to help you solve problems with others or with yourself?

4. Right half of the class, close your eyes…

8. Examples of when our intuition fails us
Hindsight bias:
Claiming we “knew it all along”
“You did a study on something my grandmother had been preaching for years”
Football games:
we credit the coach for a gusty play if the team wins
OR we blame the coach for “risky and stupid” plays if the team loses
Which is the true statement?
“Birds of a feather flock together”
“Opposites attract”

9. Examples of when our intuition fails us
Overconfidence
Tendency to think we are better at something than we actually are…

10. Overconfidence How fast can you unscramble these two? OCHSA GRABE
Have you ever looked at a study guide for a test and convinced yourself you know the material only to fail the actual test?
Did you know the material or did you recognize the material and become overconfident in your knowledge of the material?

11. When folk wisdom fails us…
"Cold hands, warm heart."
Cold hands, poor circulation. See your physician.
"Familiarity breeds contempt."
People tend to like what's familiar.

12. When folk wisdom is correct…
"Practice makes perfect."
Even brain-injured people can often learn new material with sufficient repetition.“
"Once bitten, twice shy."
Behind almost every dog or cat phobia, there's a bite or scratch.

13. How do we determine which is true and which is false?
The scientific method!

15. Example of the Scientific Method…
Observation: My toaster isn’t turning on
Question: Is something wrong with my electrical outlet?
Hypothesis: If something is wrong with the outlet, my coffeemaker also won’t work when plugged into it.
Experiment: I plug my coffeemaker into the outlet.
Result: My coffeemaker works!
Conclusion: My electrical outlet works, but my toaster still won’t toast my bread.
Refine the hypothesis: My toaster is broken.
Repeat the process until the exact cause of the broken toaster is determined

16. The Scientific Method in Psychology
Observation: Patients on one antipsychotic are more willing to be compliant with their treatment than patients on another antipsychotic drug
Question: Why are patients more willing to take one drug than the other?
Hypothesis: There are unpleasant side effects of one antipsychotic
Experiment: Survey patients: Ask how their meds make them feel
Result: One drug is produces nausea in patients more frequently than the other drug
Conclusion: Patients avoid taking the drug to prevent nausea
Refine the hypothesis: There are steps to take to prevent nausea from occurring when taking the drug

17. The Scientific Method and Psychology
Psychology is largely considered a social science because of the subjective nature of the things it studies
Humans emotions and behavior are difficult to directly measure
Often “sadness” “anger” are quantified on scales of 1-10 in psychological research, but since the data is self-reported or behaviors are observed, its ability to be exact is compromised
Therefore, the scientific method is extremely important in psychological research because it helps to standardize data over many studies

18. Psychology as a science
Most psychologists are trained to use empirical research in order to treat clients or to continue their own research
The scientific method is used heavily in psychology
Even though the data psychologists obtain are sometimes subjective, the ways in which they obtain the data are as objective as possible

19. Review: The Scientific Method
1.) Make observations
2.) Form a hypothesis
(TESTABLE prediction or educated guess based on observations)
3.) Perform an experiment
4.) Analyze the results
5.) Form a conclusion
6.) Refine hypothesis and start over 

20. Do you know your astrological sign?
What are some assumptions made about what sign you were born in?
What is a hypothesis we can test about astrological signs?

21. DO NOT WRITE ON HANDOUT
Pick up the correct handout from the baskets (the one that corresponds to your birthday)
Read each set of personality traits and choose which one best describes you.
Write the letter on a sheet of paper

22. Astrological Signs…Does your assessment match?
A: Cancer (June 22-July 22)
B: Taurus (April 20-May 20)
C: Gemini (May 21-June 21)
D: Virgo (August 23-September 22)
E: Aries (March 21-April 19)
F: Leo (July 23-August 22)
G: Pisces (February 19-March 20)
H: Scorpio (October 23-November 21)
I: Sagittarius (November 22-December 21)
J: Aquarius (January 20-February 18)
K: Libra (September 23-October 22)
L: Capricorn (December 22-January 19)

23. Issues with this experiment…
How reliable is it to use your own assessment of your personality?
Did you select certain traits because they were socially desirable?
Did you select certain traits because you already knew it was describing your sign?

24. Other Issues with this experiment…
Everyone has a 1 in 6 (16.6%) chance of selecting the correct sign
If everyone had a 1 in 12 (8.3%) chance of selecting the correct answer, the results would be more significant

25. Refine our hypothesis…
Find THREE other people to read the REAL traits of your astrological sign and ask if they agree
Best two out of three
Two ‘yes’ and one ‘no’ = yes
Two ‘no’ and one ‘yes’ = no

26. Problems with astrology
What is the phenomenon called when you claim you “knew it all along” after something happens?
How do daily horoscopes help the confirmation bias seem legitimate?
