The Einstellung effect is the brain’s tendency to stick with solutions it already knows rather than look for potentially better ones.
It’s really like a handicap, because after learning to solve a problem one way, we’re blind to more efficient methods. Our attention is locked onto familiar features and prevents us from really starting to think outside the box. It can greatly stump creative ideas and takes away any possibility of real ingenuity.
To avoid falling in this repetitive pattern, you need to inject some new perspectives in your routine, your organisation or your team... especially if it hasn’t changed in a long time.
