Lee, Not an answer, but more grist to the mill: Interestingly, if we believe in the cartesian theatre, then your points hold better - In a world in which I have perfect knowledge of my own mind, it should be impossible to perform a thought experiment, because I could never get a result that was not what I expected to get. While we could try to design a series of thoughts to lead someone else to a desired point, there would be nothing experimental about its effects on our own mind.
On the other hand, if we deny the cartesian theatre, then a thought experiment should be possible. If we do not have clear access to our own minds, then it should be possible to "test run" a series of thoughts and to find something other than what we expected. Eric P.S. After writing this, I realize that I consider one of the key features of an honest experiment that it is possible for it to result other than as we expect (which is related to my disdain of funding agencies that only fund things with sufficient 'pilot data' to virtually guarantee the promised result).
