Document Summary
Topic should be consequential for political/social/economic life, for understanding something that affects people"s lives, for predicting events that might be harmful or beneficial. Consistency with which a measuring instrument yields a certain result when the entity being measured isn"t changed. Thermometer reads the same temp at one point and then a half hour later (when temp hasn"t changed) You would like to get multiple indicators of someone"s generosity because it"s so vague. People will say they do what is thought to be socially good. - saying they donate to charity when they actually don"t -- so it"s better to also observe their behavior in order to get multiple indicators. Extent to which instrument measures what it is supposed to measure. Temperature always says it is 5 degrees above what it actually is. Pretest: you have to answer a bunch of questions about something before the experiment.
