LINE OF ACTION: A doubtful expression has much to do with the eye line. The visual cue to doubt is when a character looks up and to the left, as if trying to decide if something is true and thinking about it. The mouth also tends moves to the left side and creates a bit of a pout.

When you look to the right and up, you are making up a story or picture in your mind - visual constructing.
