The principles of scientific thinking will be the Psychology 1001 lesson that will remain with me the longest. These principles are important because they are applicable to psychology, other sciences, and the world. Ruling out rival hypotheses will help me to determine whether something is the real result or if another hypothesis could explain the idea presented to me. Correlation vs. causation is perhaps the most important as it is the most commonly disregarded. Correlation vs. causation will come in handy when someone simply presents statistics and claims that one of the variables proves the other. Falsifiability is rather simple, but still essential when reviewing claims. Replicability is important for any sort of research across academia. Extraordinary claims is a great rule of thumb for anything in life. Occam's razor is a good principle to follow when trying to explain things. These principle go far beyond psychology and I will apply them to all aspects of my life, in conversations, in school, and in decision making.
