The primary thing I got from this semester was the importance of scientific analysis. In other classes like physics and chemistry, you learn how to do tests, but do not need to draw the boundaries as clearly in other sciences as is needed in psychology, to make good scientific findings. The main concept this class taught me was to avoid the flaws that humans have a tendency to make, and to critically analyze such things as weight loss remedies and alternative medicine. I know, based on this class that herbal remedies that are suppose to cure things, have very little reliable results.
One can look at people that claim to have lost 50 pounds on an 8-minute workout. Is it because of a product or should we be looking at a rival hypothesis, like this individual's healthy eating?
Can we believe in energy medicine - the practice of manipulating undetectable energy fields going through our bodies? Since we cannot prove it wrong, how do we know it is real?
In the future I will make the effort to think scientifically about findings when making decisions like whether to go to a physical therapist, or chiropractor, and whether to believe infomercials or not.
