Document Summary
Scientific study: control over variables; running an experiment; establishing cause and effect (learned through experience). Experimentation: systematically varying aspects of the phenomenon of interest to determine how changes to these features determine outcome. Known as the gold standard (quality control) in social psychology. Falsifying hypothesis is more complicated than testing something and having it not work. Maybe we just need to do it more . Rigorous experimentation control all variables that may affect what we are studying to create a high degree of experimental control. Can say it"s likely to be false vs. likely to be true but not proved false/true . Hypothesis: an idea about how something works/what something is/why something happens based on observations of the natural world. Manipulation: to establish causality, one must determine that the observed effect happened after its cause. Independently manipulate the cause; observe/measure the manipulation"s effect; repeat. Problem: truth is more complicated than the hypothesis: replication crisis.
