The ability to think scientifically and critically is the most relevant and lasting concept to me. The reason is because scientific thinking can be applied to everyday life and continue to be used throughout my lifetime. Sure it is nice to know who B.F. Skinner was but it is not something I can see myself using often. The many principles of scientific thinking are things you can arm yourself with for your entire life and use to your advantage. I was not a very skeptical person before I took psychology and I tended to believe most things I heard. However, I now know different strategies to see what information is reliable and valid. I remember in middle school people would always take advantage of my gullibility which usually led to me embarrassing myself in one way or another. I was also the kid who would watch an infomercial on some dumb toy and be the first person to buy it, later finding out that it is not nearly as cool in person as it is on TV.
With my knowledge of the 6 principles of scientific thinking I can now avoid past troubles and be a much more informed person. Scientific skepticism is especially important in college since I will conduct a lot of research and it is important to ensure I am using valid information. Hopefully now I will know not to believe everything I hear on TV and I can use my skills to better my knowledge of my surroundings throughout life.
