Serial Position Effect

Recall bias towards initial and final items in a list.

What it is

The Serial Position Effect is a psychological phenomenon where people tend to remember the first and last items in a series best, and the middle items worst. This effect is divided into two separate effects: the recency effect and the primacy effect. The recency effect is the tendency to remember the most recently presented items best (for example, the last words on a list). The primacy effect is the tendency to remember the first few items best (for example, the first words on a list).

How to use it

Website Design and Content Placement

The Serial Position Effect can be leveraged in the design of a tech startup's website. The most important information, such as the startup's unique selling points (USPs), call to actions (CTAs), or sign-up forms, should be placed either at the very beginning or at the end of the webpage. This is because users are more likely to remember and act upon information located at these positions, thus potentially increasing conversions.

Email Marketing Campaigns

When sending out marketing emails, the Serial Position Effect can be used to increase user engagement. The most important information or call to actions should be placed either at the beginning or the end of the email. This ensures that these key points are more likely to be remembered and acted upon by the recipients, thereby driving user engagement and conversions.

Product Listings and Pricing Tables

The Serial Position Effect can be applied to the arrangement of products or pricing plans on a tech startup's website. By placing the most popular or recommended products or plans either at the beginning or the end of the listing, these options are more likely to be remembered and chosen by users, leading to increased conversions and sales.

Onboarding and User Tutorials

When designing onboarding flows or user tutorials, tech startups can utilize the Serial Position Effect to increase user retention. By presenting the most important or complex information at the beginning or end of these processes, users are more likely to remember and properly apply this information, leading to better user experience and increased retention.

App Interface and Navigation Menu Design

The Serial Position Effect can be leveraged in the design of an app's interface or navigation menu. Placing the most frequently used or important features at the beginning or end of the menu can increase user engagement, as users are more likely to remember and use these features.

Blog Posts and Articles

In content marketing, utilising the Serial Position Effect can help to increase user engagement and conversions. By placing the key takeaways or call to actions at the beginning or end of blog posts or articles, these important points are more likely to be remembered and acted upon by readers.
