Document Summary
Chapter 3: personality psychology as science: research methods. Sometimes said that the main thing psychologists know is not content but method. Jasmyn lee: firm answers to questions about the mind and behaviour are not provided often, psychologists never expect to reach final answer to question thrill is the chase not capture; goal is to improve on tentative answers. Psychologists are sensitive and even self conscious about research methodology, the way they use statistics, and basic procedures used to draw theoretical inferences from empirical data. Technical training conveys what is already known about a subject so that the knowledge can be applied. Scientific education teaches not only what is known, but also how to find out what is not yet known: research exploration of the unknown, gathering data. Two aspects of data quality are paramount: reliability, validity, combined into a third generalizable. Reliability measurements that reflect what you are trying to assess and are not affected b anything else.
