The idea that David Kibbe contradicts himself all the time is something I see frequently in non-sanctioned Kibbe spaces on the internet. In fact, this idea just seems to be generally accepted as truth.
Now, David has adjusted his thinking over the past 30+ years. He has had that much more time to think about his work. For instance, Natural, Gamine, and Classic are no longer used as Image IDs. And the way he is able to present his work now, by interacting with us, has brought a lot of clarity. But this does not mean that his work contains contradictions.
The place where I usually see this being brought up is in regard to height. David is clear on height and how it functions within his ideas of yin and yang. People will bring up a celebrity that is reported to be taller (I love Rihanna, but I never want to hear about her being a tall TR again) that David put in an Image ID that has to be shorter. This is taken as a sign that David contradicts himself, so his clear statements on height don’t matter.
Of course, we can all explain until we’re blue in the face that David believes that most celebrities are shorter than their reported heights, and that if he saw someone in person and they were clearly tall, he would change their Image ID, not his definition of the Image ID–i.e., Blythe Danner being moved from SC to FN.
But I think that this answer doesn’t address why this rumor persists. It is convenient for people to think that David contradicts himself, because then they can remain in a state of resistance. If you believe David contradicts himself, you can be whatever you want, including a tall Gamine, since any statement on his part is up for debate.
So no, David does not contradict himself. It is just that resistance is hard to get through, and people latch on to these ideas so that they don’t have to deal with their resistance. But it is the acceptance of your yin/yang balance that leads to style freedom.
