Research support for intersexual selection - Clark and Hatfield (1989) conducted a survey across a university campus where psychologists approached students and asked 3 questions (Will you go on a date with me tonight?) where 50% of females and males both responded positively. When asked "will you come back to my apartment tonight?", 6% of females responded positively and males 69%. When asked "will you go to bed with me", 0% of women provided a positive response and 75% of male responses were positive. This supports the idea that women are more picky at choosing males.
