The mere exposure effect explains many facets of our lives, such as why it’s so hard to find someone who can prepare our childhood favorites like Mom did, and it also holds when we see the latest fashion trends prominently featured in stores, catalogs, and finally on people we know.
In addition, when a trend emerges, it sends the message that it’s becoming increasingly accepted. When we see the supplies of multiple independent retailers simultaneously shift in one way, we assume the demand has shifted as well. Of course, the change may actually be driven by the prediction of a future shift in demand, which may or may not materialize, but it still affects people’s choices.
