A phenomenon in psychology in which recalling items in a list imposes an order on the list, with the first and last items remembered best.

Affinity Diagram

A data visualisation tool that can be used to explore and group people's thoughts or reactions to a set of concepts. Affinity diagrams are often used in user research and design thinking as an experimental technique for generating new ideas or solutions.

The emergent patterns in these visual representations can help identify which aspects your audience will respond well to, thus enabling decisions on the information architecture and next steps in the process.

It is important to note that affinity diagrams were initially developed for qualitative research but have since been adapted for quantitative research (though they are not typically used with statistical data).

Golden Ratio

Also known as the divine proportion, is a number, or a ratio, sometimes approximated by phi and widely considered aesthetically pleasing. The golden ratio has been featured in nature and art in many ways, including hexagonal honeycombs, the human body, and mathematics. More frequently, it is used in design and digital art to represent a path (or steps) one can take to achieve a particular look or result. In art, an artist may produce something (a painting or drawing, for example) using the golden ratio as a basis for its composition.
