In psychology there are six scientific thinking principles that we can use to help us overcome our own biases. For this claim, I will first be using the first scientific principle, ruling out hypothesis. With this principle, we can ask ourselves is this the only good explanation for this finding? We need to think about other explanations and not rule them out right away. Do we really believe that pouring salt water into a vending machine will give us free product? Wouldn't we see a lot more people walking around with free soda and goodies if that were a true statement? With this claim, we can also use the fourth principle, replicability. Someone may get lucky if they try and pour in salt water and miraculously get free food, but could someone somewhere else have the same luck with this test? We can use replicability to see if the experiment can be duplicated, if it can't, then it increases the odds that the claim is false. The last principle that I will use for this claim is the sixth one, occam's razor. This principle state that with claims, we should generally pick the simpler one. In this case the two claims you can choose from are that salt water will give you free product, or it will not. If we would apply occam's razor, the simpler or more logical claim would be that salt water would not do this for us. We use these claims to help us generate the real claims vs. the false ones. In psychology this is a very useful tool to have because we are faced with these claims on a day to day basis. If we apply these principles, we may be able to decipher scientific claims and also ones from everyday life.
