They found that men and women employed drastically different mating strategies. Men liked a large proportion of the profiles they viewed, but received returning likes only 0.6% of the time; women were much more selective but received matches 10% of the time. Men received matches at a much slower rate than women. Once they received a match, women were far more likely than men to send a message, 21% compared to 7%, but they took more time before doing so. Tyson and his team found that for the first two-thirds of messages from each sex, women sent them within 18 minutes of receiving a match compared to five minutes for men. Men's first messages had an average of a dozen characters, and were typical simple greetings; by contrast, initial messages by women averaged 122 characters.
