In my long history in these threads, I can't remember a definite example of a creo ever admitting an error. When a creo is clearly shown to be wrong, the usual response is one of the following:
1. Ignore it and bring the error up again later.
2. Insult the bearer of the correct information.
3. Change the subject to an argument about some nit-picking irrelevancy.
4. Claim that the evidence is fraudulent "just like Piltdown Man." 5. Hit the abuse button.
I can remember one from Southack on one of his "Mathematical Proof" threads where I made a point about DNA information and sequence. However, his was only a concession on verbage and phrasing; he never conceeded that the underlying model was misapplied.
