Earlier quoted context omitted.
4. People Know what they want Clearly they don't - otherwise they wouldn't be on okcupid in the first place.
What do you mean by this?
For okcupid to employ such a method, they must then be making assumption #4. However, people do not know what they want generally - and this ignorance covers what type of person would be an ideal mate for themselves. So answering questions posed about how you would want your ideal mate to answer a question, is as I pointed out, as foolhardy an exercise as asking one to construct the mind of their ideal mate neuron by neuron.
Furthermore, the people who use dating sites are just as ignorant as the rest of us about what their ideal mate might be like, or they have rejected the notion of an "ideal mate" altogether due to frustrating past experiences.
