There is a powerful force called 'The Recency
Effect' that most marketing professionals and trial attorneys know about. The
Recency Effect posits that the most recent item in a list is typically recalled
best. A similar effect is the Primacy Effect which states that the first item
in the series is the easiest to recall. Both theories point out the difficulty
of being remembered from among a dense group of other presenters.
Where possible, always try to present last. If you can't present last, then try to be the first to present. Regardless, avoid being stuck in the middle.
