The ladder theory is a funny, scientific explanation of how men and womenare attracted to each other. It also covers such topics as why women sometimes just want to be friends but men always want sex. It is based upon many years of sociological field testing, and was first conceptualized in 1994 in Exeter, CA by Dallas Lynn with acknowledgements to Jared Whitson for his role in formalizing the theory.
