You surely know by now that the Powerball jackpot is set to hit at least $550 million tonight. You should also know that your odds of winning the grand prize are somewhere around 1 in 176 million (at least, we really hope you know that). So here’s a bit of comfort for you tonight as you stare dejectedly at your losing ticket: Most lottery winners don’t end up any happier than the rest of us.

Yeah, yeah, you can probably name 550 million reasons why winning the jackpot tonight will make you happy. But here’s the truth: A handful of psychology studies over the years have evaluated the happiness of lottery winners over time, and found that after the initial glee of getting one of those big giant checks has faded away, most winners actually end up no happier than they were before hitting the jackpot.
