But the cognitive impact doesn't stop at the individual level. Research from Northeastern University on AI's social forcefield found that
AI reshapes how teams think together. When teams regularly work with AI, they start adopting AI language, AI framing and AI ways of structuring problems without realizing it. This influence persists even when AI is no longer in the room. Over time, it can erode the diversity of thinking that makes teams effective.
The warning signs are easy to miss. A team member who used to speak confidently about an account now hesitates. Priorities feel harder to set. Work feels more mechanical. These don't look like AI problems. They look like engagement problems, motivation problems, burnout. By the time the connection is made, the impact on performance is already real.
Changing The SequenceSarah's team didn't remove the AI. They changed when it entered the process.
Previously, the sequence was: Conversation happens; AI transcribes and generates insights; insights enter the CRM; team reviews what AI produced. The human was at the end of the chain, consuming output.
They reversed it. After each client conversation, team members first took time to reflect on their own—what stood out, what the client was really saying, what mattered most. Then AI generated summaries using both the human reflections and the transcript. The team reviewed and refined the AI suggestions.
The brain stayed in the loop. Ownership returned. And so did performance.
This single change—human thinking before AI input, not after—is the difference between using AI as a shortcut and using AI as an amplifier.
Three Practices For Keeping Your Team's Thinking Sharp1. Think first, then prompt.Before opening any AI tool, reflect on the problem, the client or the decision. Form your own view. Then bring it to AI. This practice is what keeps judgment and performance intact.
2. Challenge AI outputs as a team.The Northeastern research shows AI homogenizes team thinking in ways nobody notices until decision quality drops. Build a habit of questioning AI outputs together: Does this match what we actually know? What is AI missing that we can see? What would we conclude without this? The goal is to keep your team's independent judgment alive while still using AI as a partner.
3. Define what you will protect.In my book,
Clicking, I describe an exercise called Keep-It-Up and Cut-It-Out behaviors—the practices teams want more of and the ones they want to eliminate. Applied to AI, this becomes a team conversation about what good human-AI collaboration looks like for your work: what you will always do as humans first, what you will never delegate to AI and what you will regularly challenge together.
You don't need strict AI policies to avoid cognitive dependency. What you need is honest conversations about what your team wants to protect and to build norms around it.
Using AI As An AmplifierSarah's team didn't become less efficient after they changed the sequence. They became more effective—because the people doing the work were still genuinely connected to it.
AI works best when it amplifies human thinking. The question every leader needs to ask is not how much your team is using AI. It's whether your team is still thinking—and whether that thinking is still genuinely theirs.
