Document Summary
Psy100 lec3: philosophy and human physiology dealt with psychology before the science became a thing, science is not about facts; it is about hypotheses, observations and. E. g. opreationalize exposure to violent media : does the presence of factor x increase the probability of factor y, psychologists study phenomena. The likelihood: they try to figure out how to operationalize theoretical things. Exposure to violent media : there"s different ways to operationalizing things, but a lot of operationalization is partial. But if one is to take all the data, and mixes it together, then one can see the big picture: there are always holes in operationalizing. So one has to take different data and find the correlation between said data: what is left at the end is a validity question. It is possible that some other variable might be related to both things you measure which you think makes them correlate.
