We’re conducting a Twin Research Project at Harvard Medical School. If you are at least 18 years old, click here for details about this Facebook application developed specifically for our research on twins who use Facebook. The application is a fun way to compare yourself with your twin by answering entertaining questions about how similar you are, or even to find out which one of you is the “good” twin and which one is the “evil” twin.
So if you’re a twin, or know a twin, please help us out. Thanks!
