A nationwide US telephone survey3 conducted by the Pew Foundations in October 2010 asked 2625 adults ages 18 and older the following question: “Some people say there is only one true love for each person. Do you agree or disagree?” The surveyed were selected randomly, by landlines and cell phones.
The results showed 372 males “agree” and 363 females “agree” while 1005 females “disagree” and 807 males “disagree”. The number of males who responded “don’t know” was 34, and females 44.
