Welcome to Behavioural Design Pills🚀

👋🏻 Hello,
I’m Alba, a senior product designer currently crafting exceptional digital experiences at eDreams.
My journey as a designer has always had a unique focus: understanding psychology and human behavior. I’ve taken courses, attended conferences, and explored how behavioral economics can shape design.

This article marks the beginning of a journey, where I’ll share short, easy-to-digest “Behavioural Design Pills.” These insights are like little gems of knowledge that every product designer, UX, or UI enthusiast can use to enhance their work. They’re practical tips based on the psychology behind design choices.

Let’s get started!

Halo effect:

Short summary

The Halo Effect is a cognitive bias where a person’s overall impression of something is influenced by a single notable trait or positive experience.

In UX this initial impression can be used to influence users perception of other aspects, creating a general halo of positivity or negativity around the subject.

Pro tip:

Use an attractive visual design on the home page of your website. First impressions are crucial, a clean and pleasing design can create a positive impression that will extend to the overall perception of your brand, product, or service.

Example:

Apple’s attractive design, effective product presentation, outstanding testimonials and recognisable logo all contribute to the Halo Effect on your website, creating a positive impression that influences the overall perception of the brand.
