There are certain things in life that would never think about, but once someone brings it up it makes so much sense. An example is the Mere Exposure Effect. I would have never thought of that on my own, but once it was told to me, it explained a lot and reflected to be fairly true. The Mere Exposure Effect states that the more you see a person or thing, the more attractive or preferred they will be to you simply because they are familiar to you. In the rules of attraction, this plays out to be very true. The more you see someone the more attractive and pleased you are likely to become of them. Therefore, first impressions cannot be a deciding factor all of the time and love at first sight may be true, but someone you do not find to be initially very attractive could become more and more attractive with further exposure to them. In dating this is important because first dates will not necessarily tell the whole story of what could come about in regards of attraction to each other. In regards to attraction, this effect is exemplified in the link below. The Mere Exposure Effect also works in advertising, being that the more you are exposed to an advertisement for an item, the more likely you are to want to have that item. I am much less likely to go to a store and buy an item that I have never heard of because I probably have the intention of going to purchase an item I have seen advertised or have a familiarity with. As humans, we simply tend to choose the things we are familiar with rather than the unknown or unfamiliar. It is interesting to become aware of this effect because it rings true in our lives more than we realize, but we rarely consciously witness this effect.
