Stop Wasting Brain Power
Many professionals feel unproductive despite being busy, not due to laziness but because of excessive cognitive load overwhelming their working memory. Cognitive Load Theory explains that mental effort is divided into intrinsic, extraneous, and germane load, with modern work environments often increasing unnecessary extraneous load. This overload leads to slower performance, more errors, and reduced learning, especially in engineering where complex systems and constant interruptions amplify the problem.
- ▪Working memory is limited and can be overwhelmed by excessive cognitive load, reducing productivity and increasing errors.
- ▪Cognitive Load Theory identifies three types of mental effort: intrinsic (task difficulty), extraneous (unnecessary distractions), and germane (effort that builds understanding).
- ▪In engineering, bloated systems and constant interruptions increase extraneous load, leaving little room for deep problem solving or learning.
- ▪Poorly structured codebases and workflows force engineers to spend time navigating complexity rather than solving actual problems.
- ▪Reducing extraneous cognitive load allows teams to work more efficiently, make fewer mistakes, and develop deeper system understanding.

PostSpaciousEditorialStop Wasting BrainpowerPublished October 3, 2025 · 10 min readHow many times have you found yourself saying: “I worked all day, but I didn’t get anything done.” I know, we have all been there. We feel bad about it, too. On the surface, it looks busy. Your calendar is full, Slack is notifying you, and your todo list is endless. There’s no shortage of movement, and yet, strangely, very little progress. If you’ve ever felt this way, you’re not alone. I wish it was as simple as laziness or poor time management. What’s actually draining us is cognitive load. Our brains aren’t running on infinite RAM. They choke on noise, interruptions, and the dumb complexity we keep piling on. Psychologists define it simply: our working memory is limited.
