The holiday season is fast approaching, and that means it’s time for gift buying. With each passing season, finding the perfect gift for loved ones seems to become more and more difficult—a phenomenon not unrelated to the seemingly exponential growth in buying options each year.
So how do we do it? Many of us would like to believe that our decision-making is based in logic and objectivity. Clearly you’ve chosen the coolest plaid neckerchief for your hipster cousin—you got the thing at an Urban Outfitters! Neuroscience reveals that deciding what we prefer based on a few options is not always based on inherent qualities, but rather is highly biased based on expectations.

Snow-lovers rejoice—winter is coming!
And no, this isn’t an allusion to Game of Thrones. With the end of Daylight Savings, the days are becoming darker earlier, which for some can mean the onset of the winter blues. The medical term for this is Seasonal Affective Disorder (SAD), a condition caused by a mélange of changes in our biological clocks, serotonin levels, and melatonin production, all of which affect our mood.
While many of us are familiar with SAD, there are, in fact, people that get SAD in reverse. For a small group of people, the dark days of winter don’t elicit depression, but renewed vigor and improved mood.
