## Details

## Overview

Attention Residue Minimization is a productivity technique based on research by Professor Sophie Leroy showing that when you switch from Task A to Task B, your attention doesn't immediately follow—a residue of your attention remains stuck thinking about the original task.

## The Science

This residue gets worse if your work on Task A was unbounded and of low intensity before you switched, but even if you finish Task A before moving on, your attention remains divided for a while.

## Impact on Performance

Attention residue reduces cognitive capacity available for the new task, leading to:

- Decreased focus and concentration
- Lower quality work output
- Increased errors
- Slower task completion
- Greater mental fatigue

## Minimization Strategies

### Complete Task Closure
- Finish tasks completely before switching when possible
- Create clear stopping points if task can't be completed
- Document where you left off for easy restart

### Transition Rituals
- Take a short break between tasks (5-10 minutes)
- Physical movement to reset attention
- Brief meditation or breathing exercise
- Clear your workspace between tasks

### Task Batching
- Group similar tasks to reduce attention shifts
- Complete all tasks of one type before switching to another
- Minimize the number of different task types in a day

### Time Blocking
- Dedicate specific time blocks to single tasks
- Protect blocks from interruptions
- Schedule buffer time between different task blocks

## Benefits

- Improved focus on current task
- Higher quality work
- Reduced mental fatigue
- Faster task completion
- Greater sense of task completion
