The study found that an overwhelming 83 percent of those they surveyed ended up being disappointed with their New Year’s Eve celebration. And the people who were the most let down were those with the highest expectations.

Those who were expecting to attend a big party on New Year’s Eve ended up being the most disappointed, followed by those who planned a small party, followed by those who had no plans to celebrate. Similarly, those who had anticipated enjoying New Year’s Eve and expected to spend time on preparations for the event were significantly more likely to say they were disappointed afterwards.

The researchers can’t be sure just why this happened. However, another study they did around the same time supports the idea that trying to feel happy is one of the quickest ways to undermine your own experience.
