This reminds me of an interesting thing I read about intelligence where there's an important level of intelligence that very few animals exceed where basically you can't conceive of the concept of others knowing something that you don't or vice versa.
The example used in the study I read about it went like this: Christine has a cookie and she walks into the kitchen and puts it in the first of two cookie jars, then she leaves the room. Justin goes into the kitchen and moves the cookie from the first jar to the second jar. Christine comes back to look for her cookie, in which cookie jar will Christine look?
If an animal fails this test then they'll guess that she'll look in the second jar because they can't comprehend that she doesn't know what they know -- that Justin moved the cookie. As a result, any animal that has failed this test and can communicate with us -- mostly apes who communicate with sign language -- have never asked us a question for information because they can't conceive of the concept that we know anything that they don't.
