Dec 13 - Threats to Validity: What You Should Know to Interpret Research Findings, Fran Featherston, Ph.D.

Our lives are full of findings from  research results. Not all of the claims  they make are valid. Some studies use  samples that are not representative.   Other studies make claims when they have no comparison group. The question  wording or even question order can bias  survey results.  How do you know when  you can trust the research claims?  What do you need to look for?

This talk will give you tips to judge the research you read. We look at examples from the current news and discuss what you need to know to judge whether the research finding can be trusted. We will discuss the threats to validity for each study and whether the research meets the standard of reproducibility. That is, could another researcher possibly reproduce this finding?

Nov 15 - Skeptical Journal Club: How To Read A Medical Study John Cmar, MD

One of the most important aspects of being a healthy skeptic is knowing that just because a scientific study was done on a topic does not mean the study was done well, or that the conclusion the authors reach is supported by what they actually did. But when someone states that a particular study has major flaws or was well-done, what precisely does that mean?

Join us as we analyze two different journal articles in detail, focusing on the good, the bad, and the ugly of how studies are done and interpreted. Saturday, November 15, 2014

Oct 11 - Not Your Parents' Gospels: Historicity, Literary License, and the Crafting of the Gospels - Natalie K. Houghtby-Haddon, Ph.D.

In this talk we will explore how the Christian gospels came to be written, what their purpose might have been, and how ancient communities may have understood the "truth" of the gospels, in comparison to modern audiences. For example, how might the first followers of Jesus understood his role as “miracle-worker”? We will also consider how myth-making and social formation go together, as a way to create new or alternative communities of interest. ...
