The serial position effect is the psychological tendency to remember the first and last items in a list better than those in the middle. The serial position effect is a form of cognitive bias, and it includes both the primacy effect and the recency effect.

People’s likelihood of remembering first thing and last thing is much higher compared to remembering things that happened in the middle.

This is why advertising during the world cup or super bowls is more expensive if they are first or at the end because that’s what most people remember afterward. So, as a marketer, what you can do is tell people the MOST IMPORTANT thing at the beginning and then fill up the middle with evidence and Talk about the “take home point” at the end.
