Document Summary

Scientific skepticism: a willingness to , keep an open mind to all claims. Choose participants: population, the entire group that is of interest to researchers, sample, a portion of any population that is selected for the study, random selection, randomly choosing a sample from a population. Controlling your experiment: progressive error, by doing something multiple times. This is true (cid:374)ot (cid:373)atter (cid:449)at (cid:449)e"re (cid:373)easuri(cid:374)g. Averaging: to control for random error we use averaging, measure repeatedly and take the average. Research design matters: helps eliminate biases, we want to avoid subjective impressions at all costs. Cognitive biases: systematic errors in thinking that can lead to confidence in false conclusions (caused by heuristics) Heuristics: mental shortcuts or rules of thumb, they reduce the cognitive energy required to solve problems, the trouble is when they oversimplify reality. How do we avoid biases and heuristics: test specific hypotheses derided from broader theories, theories are (cid:374)e(cid:448)er (cid:862)pro(cid:448)e(cid:374)(cid:863) (cid:271)ut h(cid:455)potheses (cid:272)a(cid:374) (cid:271)e (cid:272)o(cid:374)fir(cid:373)ed or dis(cid:272)o(cid:374)fir(cid:373)ed.
