Salience

Shrink Definition

Salience refers to how much a stimulus stands out and captures the brain's attention because it's perceived as important. Salience isn't determined solely by the outside world. It also depends on internal goals, emotional state, past experiences, expectations, novelty, and biological needs. The brain continuously filters enormous amounts of incoming information, allowing only a small fraction to receive focused attention.

Plain language

Some things naturally grab your attention because your brain believes they matter.

Shrink Insight

The brain doesn't treat all information equally. It constantly ranks what deserves attention.

Salience isn't identical to importance. The brain sometimes treats insignificant events as highly significant.

Shrink Takeaway

Attention begins with what the brain decides matters.
