Description
Jan 11 Soc Psych Confirmation Bias - Why did you find what you expected to find? o Finding only what we expected to find (bias in design in experiment, way we talk to subject, (simply asking questions may change behavior in subjects) o Blind experiments (the experimenters being aware or unaware to hypothesis, experimenters may subconsciously emphasize certain instructions, and leading them in the direction of the hypothesis, if they are unblind (knows hypothesis). o Experimental Demand (aka, Demand) – subject knowing what you want and doing it.  Why did you find what you found?  Want to avoid this  Want subject not discover your true hypothesis (use cover story)  Blind Ss  Cover stories  Cover story must misdirect without effecting the behavior of subjects that effects hypothesis How to Create your own findings (Vokey and Read 1985) - Confirmation bias and demand often work together o Judas Priest song played backward -*do it, do it* suicide case and parents sue - Ss listen to backwards – recorded passages from the Bible and Jabberwocky - IV: Instruction o Group 1 (not primed to hear satanic messages) “ tell us what you hear in this recording” o Group 2 (primed to hear satanic messages) “do you hear any Satanic phrases?” - DV: % of Ss whos report hearing Satanic Messages o Group 1 Results – only 1% of subjects reported satanic messages (nothing) o Group2 resuts – 90% reported satanic messages  Created results to demand, the question frames the result and behavior of the subjects.  Ask questions like Group 1 not Group 2, due to question creating misleading results Whe’ve Collected Our Data: Now What? - Analysis of data to determine wheather your findings are statistically significant o E.g, mean differences tets  Is group A statiscially different from group B?  If not, then if isn’t different even if it looks different on a graph? - E.g.
