Jury prep is a difficult "science." There is a tendency on both the part of the witness and the lawyer to want to come away as competent and all knowing.

"I think"; "it seems as though"; " I believe"; "maybe" are all answers that to the attorney appear to be weak and not "selling" the theory of the case, well enough.
Now there is a new study out that verifies my suspicions. According to a new study at Cal Berkely an over confident witness who makes mistake on the stand is far more likely to anger a jury than one who seems unsure of himself.
