Critical Thinking III Doing research Dave Van Valkenburg Psychology 1101 Outline • Scientific theory • The necessity of control experiments • Essentialism versus operationalism Scientific Theory The misconception of scientific theory • The non-scientist uses the word ‘theory’ in a very different way to the scientist. • To the non-scientist: a theory is a guess, a hunch, a gut feeling… great for cocktail party discussions. • One theory is as good as the next… Scientific Theories and Hypotheses • In science, a theory is an interrelated set of concepts that is used to explain a body of data AND to make specific predictions about the results of future experiments. – Falsifiablility! • The latter part is the def’n of a Hypothesis • Some theories ARE better than others! – They’ve had some or many of their hypothesis confirmed.
