What is the definition of Selective Studies?

"Selective studies are like choosing which flavors of ice cream to keep in your freezer, but instead of vanilla or chocolate, you're picking the ones that make you look good to the world while ignoring all the other, potentially more interesting flavors."

Example sentence: "The selective studies on the benefits of sunburned skin were so skewed they made me question if my dermatologist was secretly a fashion model."
