Does not yield replicable results- we know in a lot of ways we make it hard to replicate, but it does, even when the toughest critics try to replicate they have some success. We are trying to prove that more & more all the time· Can’t make precise predictions· Not useful to societySupreme court: Daubert vs. Merrell Dow (1993)· Case established admission of expert testimony in court (strictly defined scientific expertise) · The court defined: o Scientific knowledge = scientific method/ Methodology: A conclusion will qualify as scientific knowledge if the proponent can demonstrate that it is the product of sound “scientific methodology” derived from the scientific method.o The process of formulation hypotheses and then conducting experiments to prove or falsify the hypothesis· Factors that judges should use in considering whether testimony is “expert” :

1.Whether the theory or technique employed by the expert is generally accepted in the scientific community2.Whether it has been subjected to peer review and publication;3.Whether it can and has been tested4.Whether the Known or potential rate of error is acceptable; and 5.Whether the research was conducted independent of the particular litigation or dependent on an intention to provide the proposed testimony · Rules out claims of special knowledge, anecdote, intuition and testimonials – pseudoscience and junk science · Enormously helpful for upholding psychology as a science The nature of our science (revised from Stanovich)· Psychology progresses by investigating solvable empirical problems· Psychologists propose operationally defined concepts to test falsifiable theorieswe define things by how they’re measured; we will either support it or not support it (NOT.. “if you would’ve tried harder you would have gotten an answer)· These theories are tested by means of systematic Empiricism and results are available for replication and criticism after publication via peer review.· Psychologist use many different methods to arrive at conclusions and the strengths and weaknesses of their methods vary Some methods are very strong, some aren't. Some are marginal but they are all we have. Some self-report measures don’t have as much validity as we want but we don’t throw them out, we do everything we can to strengthen them· The behavioral principle that are eventually uncovered are almost always probabilistic relationships (that is, explained as a probability) We explain our results of studies as how our result is different than random occurrence/chance (probability)· Most often, knowledge in psychology is acquired only after a slow accumulation of data from many studies each containing flaws but nonetheless converging on a common conclusion.We shouldn't ever make a big statement/conclusion after one study, we accumulate from many studies. Every study has limitations in the discussion section but nonetheless all the convergent studies come to a common conclusion Two most important skills for studying psychological science· Tolerance for ambiguityo The level to which one is capable of accepting situations having conflicting or many interpretations or results-

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
