When you meet someone through online dating and get together in person for the first time, it takes less than one second to decide whether you find them physically attractive. If that person is too short, too tall, too old, too young or whatever, you immediately eliminate them as a potential partner. But if he or she fits your general concept of what's appealing, the next thing you'll respond to is voice. Again, it takes just a second to make a judgement you might not even realize you're making. Rapid talkers are considered to be more educated, and men with deep voices are usually perceived as being better looking than they actually are! Next, you'll actually listen to the words being spoken. We're naturally drawn to those who use the same kinds of words we do, and can quickly sum up a person's attributes from a short conversation. Of course appearance matters, too, but really it's within the first three minutes of meeting someone new that we size them up as a potential partner. Psychologists also say that the more you interact with someone you like, the more you come to regard them as being attractive, smart, and similar to you (unless you discover something that is a total turn-off). So it might be wise to hang in there for a second date if those first three minutes signal a potential new romance!
