Attention is the limited cognitive resource we allocate to what we perceive and do. In design, it is what decides what will be seen, understood, or simply ignored.

The groundwork was laid by Herbert Simon back in 1971, in a prophetic statement: "a wealth of information creates a poverty of attention." As information continues to explode, attention becomes the true scarce commodity, and thus the centerpiece of a whole new economy. An entire segment of digital design has been built to capture it: notifications, infinite scrolling, autoplay, and variable rewards.

This creates a profound moral tension at the heart of our craft. Capturing attention is easy and highly profitable; it simply requires exploiting our basic reflexes. Respecting it, however, is a much nobler challenge: helping users accomplish exactly what they set out to do, and then gracefully letting them go. Designer Tristan Harris popularized this vital critique through Time Well Spent: too many interfaces are optimized for time spent, rather than time well spent. Capturing and respecting pull in entirely opposite directions.

It is never a question of features, but of intention. The exact same notification can be a wonderful helper (a timely reminder) or a disruptive parasite (a nudge just to reopen the app). Attention captured against a user's will is a loan that cannot be repaid—and it is paid for in trust.

Our guiding principle is simple: design for the user's focus, never against it. Outstanding design helps people concentrate on what truly matters, then steps back elegantly. True performance is not measured by time captured, but by goals achieved without distraction.

What's happening elsewhere: dark patterns (captured attention), cognitive biases, cognition and cognitive load, affordance, and design ethics.
