This brings new meaning to the term “speed dating.” Research found it takes us just 12 minutes to decide whether we’re attracted to a potential new partner! We judge our date’s smile first, followed by whether they make eye contact and their tone of voice. On the negative side, the number-one most off-putting feature is body odor (gross!), followed by bad breath and excessive swearing. A quarter of singles work overtime to impress a first date by making changes to their appearance. For women, that means a manicure, haircut or new perfume, and for men, it’s growing sexy stubble. Some people even go on diets before big first dates! Of course, one way to get a jump on the judgment process is to do your research beforehand- 6% of people vet their first dates on Facebook and Twitter.
