Two things surprise me.

First while 73.4% of responders are consequentialists and only 9% deontologists, at the same time 45% of responders are libertarians. While labels like that are vague, libertarianism is in most versions highly deontologist ideology, and cares about processes and not results as such.

The other thing was 33.3% of "single and looking" (plus 24.2% of "single and not looking" consists of some mix of "single and not interested" and "single, tried but given up"). There are some well known seduction techniques based on adjusting for biases people have because we're evolutionarily adapted to a different environment. I'd guess most responders compartmentalize their rationality and do not apply rational thinking to their personal lifes. More compartment-busting posts please?
