The UK's AI Security Institute ran a controlled workplace trial and found that participants using AI scored 25% higher overall and achieved 61% more output per minute on standardized tasks.

What We Discovered: The Upside is Real
The data confirmed what we’ve felt in our best moments: when AI is used for structured, knowledge-heavy tasks, the gains are massive.
- We’re moving faster: Trials show task completion times dropping by 15% to 50%.
- We’re doing better work: Research from the UK’s AI Security Institute found that AI users scored 25% higher on quality and achieved a 61% increase in output per minute.
- We’re saving time: About 20.5% of frequent AI users are reclaiming 4+ hours every single week.
Perhaps most exciting for our team is the "skill compression" effect. AI helps bridge the gap between junior and senior performance, empowering everyone to level up together.
The Warning Sign: "AI Brain Fry"
But we also found a darker side that many consultants ignore. We encountered a phenomenon researchers call "AI brain fry".
- Mental Fatigue: 1 in 7 workers report significant cognitive strain from managing too many AI systems at once.
- The Complexity Trap: When workers have to constantly supervise and context-switch between tools, they make more mistakes and feel a stronger urge to quit.
- The Turnover Risk: AI-related fatigue is directly linked to higher burnout and turnover intent.
At Strataigize, our Strategic Director, Abbey Dela Cruz, puts it best: "Measure the productivity gains and the human costs. We have to watch for mental fatigue with the same rigor we apply to output".
