We learned about quite a few different topics this semester. However, from attraction to abnormal psychology, the one thing that remained constant was the use of scientific thinking. The six principles of ruling of rival hypotheses, correlation vs. causation, falsifiability, replicability, extraordinary claims and Occam's razor guided our exploration of each topic. I think these are ideas that can help you evaluate claims and situations throughout your life and this is why the book and lectures made a point of trying to ingrain them in us. We're learned a lot about how easy it is to unknowingly bias our opinions through things like the confirmation bias or availability heuristic, some examples of which are shown here. We also learned how to avoid these types of things through scientific thinking and in 5 years I hope I am still actively challenging my ideas and opinions through these methods.
