The Skill AI Can’t Replace: Why Critical Thinking Is HR’s Most Urgent Priority

Here’s why critical thinking is HR’s most urgent skill in the AI era, and how to embed Human-in-the-Loop practices across your teams.

As AI becomes a daily part of work, it’s tempting to lean into speed, convenience, and automation. But in HR, where decisions affect real people and the high cost of getting things wrong, no tool can replace the value of human judgment and critical thinking.

In shifting from our focus on building AI tools, we now look more broadly at employee AI use. At SHRM 2025, Mitratech’s resident AI experts Susan Anderson and Aimee Pedretti made a clear case for why HR professionals are well-positioned to lead the charge in building a culture of thoughtful, responsible AI use.

AI Can Do the Work, But It Can’t Make the Call

LLMs like ChatGPT and Perplexity are great at surfacing patterns, generating first drafts, and speeding up certain tasks. But they don’t understand organizational culture. Your organizational culture. They can’t weigh ethical tradeoffs or read a room. And their output isn’t always accurate.

That’s why Anderson and Pedretti argued that what remains critical is a culture of collaboration — where AI augments Human-in-the-Loop judgment rather than replaces decision making or conclusions. The real value comes not from handing decisions over to AI, but from using these tools to support thoughtful, human-led work.

“It’s Our Job to Question the Answers”

One of the most compelling lines from the talk that stuck with me was a quote that’s effectively become a motto of the Mitratech engineering team:

“AI answers questions. Our job is to question the answers.”

While “trust but verify” might be a catchy buzz phrase in relation to AI, a more appropriate phrase is to first verify then trust AI output. Yet many employees aren’t doing this.

A KPMG study found that two-thirds of employees are not reviewing AI output before using it in work products. Similarly, research conducted by Microsoft points to over-reliance on AI output particularly when the user is less confident in the topic. Employees aren’t reflecting on whether they are using AI tools appropriately and they’re often using AI in ways that could cause risk for employers.

Critical Thinking Is the New Baseline

HR must build a workforce that thinks with AI, combining creativity and innovation with scrutiny, productivity with pause. Anderson and Pedretti emphasized that every employee now has a role to play as a human in the loop.

The KPMG study mentioned above highlights risky employee behaviors: 66% use AI outputs without critical evaluation, 56% report making mistakes due to AI use, 48% have uploaded company sensitive data into public tools, and 63% have seen/heard employees using AI inappropriately. According to this study, only 47% of employees report receiving AI training and only 51% believe they can use AI effectively.

Again, this calls for embedding the “Human-in-the-Loop” mindset across the organization, fostering critical thinking as the baseline skill when working with AI. While AI can boost productivity, there’s a risk of employee overreliance on AI.

HR leaders who create the conditions for smart organizational AI adoption:

  • Focus on more than enhanced productivity — this can come at a cost.
  • Foster a culture where every employee understands they play the role of “Human-in-the-Loop.”
  • Educate against passive AI consumption and of the importance of critically evaluating AI output.
  • Create space for deep thinking and reinforce the continual learning of domain expertise.
  • Teach AI prompting best practices and pitfalls.
  • Are intentional about where AI is used and where it doesn’t belong.

When We Stop Thinking, We Stop Learning

Anderson and Pedretti also cited early MIT research showing over-reliance on AI dulls our thinking. Students using AI tools wrote weaker essays and retained less of the content behind their assignments. Putting their work in “cruise control” apparently removed the ability for learning, growing, and gaining strength in expanding thought. This becomes a self-reinforcing cycle as future work is performed on a weaker foundation, and it’s something to watch for as AI adoption spreads.

The same thing is happening in the workplace. When employees copy-paste AI output without thinking, they lose the opportunity to grow, solve, and stretch their skills. The very process that makes work meaningful begins to erode.

What HR Can Do Now

HR leaders are in a powerful position to shape how AI shows up across the organization.

Start small: Discuss the risks of over-delegation and over-reliance on AI. Ask managers to review AI-generated work with their teams and talk through what’s working, and what’s off. Normalize critical evaluation of AI output at all levels of your organization.

Tone at the top: As Anderson and Pedretti make clear, leaders across the organization and their actions set culture from what they measure, what they celebrate, and what they control or discipline. Create a culture where the right behaviors (innovation, learning from failures, and celebrating responsible AI wins) can create the right environment for exploration and quality.

In the end, the most powerful tool in your tech stack isn’t AI. It’s your people, thinking clearly, asking better questions, and leading with judgment.
