An american behavorial study concludes that 52.6% of men lied about their height, compared with 39% of women. But 64.1% of women did not tell the truth about their weight, compared with 60.5% of men. Also, 24.3 percent of men lied about their age, while 13.1 percent of women did.

According to an assistant who worked on the subject, participants try to find the good balance between 1) appearing as attractive as possible 2) being perceived as honest during the deception first meeting.
