subconsciously favoring the more known does not imply a total disregard for the less known.
Firstly, it's not subconscious - try answering the questions in the last thread. No, the one does not imply the other: my statement about the lack of fuck-giving is a posteriori rather than a priori. We each have but a few fucks to give, one must prioritise.
Here's what happens when one tries to give more fucks than one humanly can: http://en.wikipedia.org/wiki/George_R._Price#Helping_the_homeless
It is an evolutionary fact that the fuck demand outstrips the fuck supply. Rations are rational. Humanist logic isn't, sorry atheists! :'(
