How do we reconcile the discipline and rigor of good research with the ambiguity of human emotions and motivations? What is the role of research in psychology?

DQ 1: More and more, we are asked to document impact and to measure outcomes. We are asked to provide information about a variety of things through as many varieties of ways. When we go to stores and they ask us for a zip code or phone number. The list could go on and on. You text talks about descriptive statistics and suggests that they are used to make a group of numbers understandable in a research study. While that is certainly the case, we use descriptive statistics in a number of other ways.

DQ 1: Please read the following article in your Electronic Readings, Null Hypothesis,

CLOSED THINKING: Without scientific competition and open debate, much psychology research goes nowhere

DQ 2: It is suggested that significance tests should be banned for two reasons, (1) that there is a tendency for researchers to accept the null hypothesis as true because the result is not significant and (2) significance is confused with a large effect size.

DQ 1: Thomas Bayes who was an English Clergyman in the early 18th century who is known for the Bayes' Theorem. The theorem suggests that science is about conducting research in order to adjust our preexisting beliefs in light of the evidence collected. Conclusions drawn from an experiment are always in the context of what we believed about the world before the experiment.

Others suggest that it is better not to make any assumptions about prior beliefs. (Aron, Aron & Coups, 2006)

Where do you weigh in on this debate? Do you think we do research in order to validate something we already believe to be true or false?
