>Of course, you can bet that the writers of the test did not use anything related to algorithmic complexity when deciding the correct answers to these questions.

Allow yourself to entertain the thought that they did. Imagine programs in our brain. Things that are easy to decode/(de)compress and require little energy/instruction are of low algorithmic complexity to them.

Start writing down farm animals in your mind. How long before you get to "hen"? You may have written down "chicken", but that would be too easy for a Mensa question, so you'd have to substitute that one :P

Wrong or obscure "answers" to a test question take more energy to produce, they are more complex, more random, less orderly. For me, "Cow" is the shortest program that gets executed first when I think of farm animals. It was likely one of the first programs for the test writer too.
