Not necessarily. Consider this bit of information from Dr. Shors:
[T]he people at the party who were not assaulted or stressed by the event are not as likely to remember it. For her, it was a memorable event; for them, it may have just been another time hanging out with few friends hanging at a house. This applies to the people downstairs but perhaps even for the two boys, especially if they were intoxicated.
But why can’t Dr. Ford remember the date of the event? This may seem like a huge clue to the veracity of her claims, but memories surrounding sexual abuse are not very tidy.
Richard McNally, a psychologist at Harvard University and the author of the book Remembering Trauma, gives an example of being a clerk at a convenience store and robbed at gunpoint.
Which parts of that memory get encoded into the brain?
Not all the details, even important ones. Here’s what McNally wrote in an article for NPR:
The person may often encode the features of the weapon, the gun pointed at him, but not recall whether or not the person was wearing glasses…When somebody has an experience such as this, they’re not necessarily saying, ‘I better get down the address.’ They’re preoccupied with trying to escape this terrifying experience.
