Serial Position Effect

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. That is, if given a list of words to remember like "dog apple tree", people will tend to recall "dog" as being at the beginning of the sentence and "tree" as being at the end of it.

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).

Hex Code

Design Debt

A concept used in systems design to describe the negative consequences of making seemingly innocuous design changes. Shorthand for a product's delayed but inevitable need to be reworked due to earlier, seemingly trivial decisions not having been fully thought through in the original release.

Designers incur this "debt" by making quick and easy choices that save time in the present but cause more complex problems later on down the road when it becomes necessary to change or add something.
