The Reductionist Manifesto

This is a bunch of brief notes on reductionist design, that I intend to iterate upon, as basis for my own practice and my classes.

Reductionism is an approach relevant to interaction design.

It acknowledges that human attention is a rare resource, because of cognitive overload and a rapid evolution towards shorter attention spans.

For a piece of interaction design to be called “reductionist”, it should follow these guidelines:

0. Human first

  1. Because it’s the user who makes the experience. What we design are not the user experience, but the parameters for experience. This is why some people favor the term “meta-designer” instead of “user experience designer”.

1. content first

  1. Use as little means as possible. That’s the most important rule, it’s the reductionism’ mantra.
  2. Start with the text. Brevity, efficiency, accuracy, musicality & rhythm.
  3. Make sure the text is legible.
  4. Avoid decoration at all cost. Decoration is expensive in bandwidth and offers more distraction than meaning.
  5. If you must use visuals, again, use as little means as possible. Use geometrical shapes, as they provide greater cognitive efficiency.
  6. Visual clarity is achieved by the thoughtful appliance of gestalt (hierarchy through the use of grid and white space, focal point, grouping, contrast).
  7. Style and personality emerge from a graphical system made of copywriting, typography, colors and the occasional logo or iconset.

2. mobile first (on the web)

  1. Bandwidth optimisation (Serverside Responsive design in addition to guideline 1.1).
  2. Adaptive/responsive layout.
  3. Provide mobile application icons and if relevant, startup images.
  4. Favor svg as image file format, unless, you know, a photo.


That’s the spirit! gives life to dead words by using a lot of white space, visual hierarchy, typography. The only image is the author’s portrait, to trigger the human ability to quickly read faces so as to make the content and the reader “click” together.

Otl Aicher’s Opera programme is a great example of visual hierarchy with as little means as possible.

No makeup, only substance, radical constraints. Perfect execution.

If you are interested in mastering reductionism, you should probably start by exploring the Gestalt laws of perception so you have some knowledge on the constraints of the human perceptual system. Here are the five main laws.

  1. Gestalt Principles 1: Figure/Ground
  2. Gestalt Principles 2: Similarity
  3. Gestalt Principles 3: Proximity, Uniform Connectedness, and Good Continuation
  4. Gestalt Principles 4: Common Fate
  5. Gestalt Principles 5: Closure

Then practice by reducing, reducing, and then reducing some more.
