I'm also no expert in the field, to be clear.
I'll leave aside Knox-specific articles (which could carry bias), but here's an explanation of CIFCs:
"Coerced-Internalized Confessions
This is the most psychologically complex type of confession in which innocent people come to believe they may have actually committed the crime. This can happen when:
- Memory is impaired (due to stress, exhaustion, or substance use)
- Interrogators convince them they have repressed memories
- They are presented with false evidence that seems compelling"
Knox was exhausted and stressed.
She was told that she had trauma-induced amnesia, and told to try and unblock her repressed memories of Patrick (specifically) murdering Meredith.
She was told that:
- falsely - that there was evidence that confirmed her presence at the scene;
- falsely - that they already had identified the suspect;
- truthfully - that the suspect was black (which is why the pushed her to "remember" it was Patrick):
- falsely - that her Sollecito had retracted the alibi (that he was with her overnight, at his house).
I do think those three common factors seem conclusively checked off.
Her statement does also confirm that she had repeatedly told police that she was not confident that what she was seeing in her head, at their demand, was accurate.
And I still just find it very hard to believe that she cobbled together that note in a sophisticated, less than honest fashion, so soon after the interview and after limited sleep - particularly as there's nothing in it which would be helpful to her case, and if she was being self-protective the obvious thing to do would be not to make any further statement until speaking to a lawyer.
I totally get that the psychology is hard to readily accept, but it is a known phenomenon, her statement aligns with the phenomenon and the circumstances that produce it, and there's no good alternative explanation for why she would have made any of the statements otherwise (particularly now that we know the actual murderer and that Knox's involvement is all-but-impossible).
