There’s one small rule I’d hold onto. Keep one rep a week for yourself, no tool allowed. Your judgement is the product clients pay for, and judgement is built out of reps. The tool now produces a first draft in seconds, and skipping the rep feels like found time. Some weeks it is. That’s the quiet tradeoff between AI and critical thinking. The draft gets faster while a skill you stop practising fades, and it fades first in the calls only you make.
Canadian firms are putting real effort into AI training. Statistics Canada found 21.6% of businesses using AI gave AI training to their existing executives in the year to spring 2026. The use is already on the floor, too. In Alberta, Statistics Canada found 21% of workers used generative AI in their main job between September 2024 and July 2025, against 22% nationally. The training matters less than the order you use the tool in.
When did you last write something hard with no help at all? Not the final polish. The first pass, the one where you find out what you actually think. If the honest answer takes a while, that’s the signal. When the tool becomes the first move on almost everything, your own first move gets rusty.
Nothing broke. That is the trap. The drafts were fine, sometimes better than fine. What changed was the order. I was reading positions before I had formed one, nodding along to a version of my own thinking that arrived before the thinking did.
What counts as a thinking rep?
A rep is one unassisted pass at a problem your name goes on. You sit with the blank page and you commit. This is my position, here is why, here is what it costs. The page can be rough.
Rough is the point. Sorting a jumble of half-formed thoughts into a position you would sign is the exact motion that built your judgement over the years.
Owners do this work more often than they count. Deciding if a job is worth taking. Answering the client note that needs care, not speed. Working out why a good person on your team is struggling. Each one starts as a first draft in your head, and each one trains the same muscle.
Judgement grows the same way it was built, one honest rep at a time. On the bigger calls, I’d also write your own lean down before you read the AI’s recommendation.
Where does the fade show up first?
It shows up in the calls nobody else in the firm can make. Routine work hides the fade for a long time, because routine work carries a standard you can check against. The owner-only calls have no checker.
Is this client a fit? Is this hire the right bet? Is this the week to say no to work you would normally take? Those decisions run on feel built from reps, and feel built from reps is exactly what thins out when the reps stop.
The hard part is that nothing warns you. A fading skill sends no notice. You find out on the day a decision mattered, looking back at a call you would have made better a few years ago, wondering when your edge went soft.
The calls only you can make are the first place a skipped rep collects its payment.
Why is the tool not the problem?
The tool is not the problem. Order is. Prompt after you have a position and the tool becomes a sparring partner. It argues back, finds the weak paragraph, offers the angle you missed. Prompt before you have one and it becomes the author, and you become its editor, approving work you did not think through.
I’d apply the same order to your team. Hire strong people and teach them AI second, because judgement comes first and the tool rides on top of it. For your own week, that means position first, prompt second.
Prompt second and the tool sharpens your thinking. Prompt first and it stands in for it.
What does one protected rep a week look like?
It looks smaller than you expect. One piece of writing that carries your name, drafted with your own hands before the tool sees it. A position note to a client. The first pass on a proposal argument. The reply where the wording has to be yours because the relationship is yours.
Twenty-five minutes, blank page, no assistance until your position is down in full sentences. I’d protect that slot the way you’d protect a client meeting.
Handwriting is not required. A blank document works. What matters is that the first version of your thinking comes from you, at full effort, while it is still hard. The reps that grow your people run on the same rule. Checked reps on live work are what decide who becomes your senior, and the ladder works the same way at your own desk.
Nobody gets sharper by approving drafts.
After the rep, open the tool and let it work. Ask it to attack your position. Keep what survives, cut what does not, and notice where it beat you. That noticing is training no course can hand you, because it is measured against your own judgement on your own work.
How do you start your weekly thinking rep?
Start Monday with the rule written down where you will see it. Write my position before I prompt. Then pick the one piece of work this week that carries your name and give it an unassisted first draft.
One rep. That is the whole program. It costs less than half an hour, and it protects the one asset your firm cannot bring in from outside.
Hold the line for a month and watch your prompts change. They get shorter, sharper, and more certain, because they now carry a position instead of a hope. If you want reps like these built into how your whole firm trains, my AI training workshops run on live work, yours included, with the owner’s own thinking treated as part of the standard.
Pick this week’s rep tonight and block the twenty-five minutes. I write about reps like that each week in the AI Newsletter with ZAK.
What people ask about AI and critical thinking
Does using AI weaken critical thinking?
It can, when the tool goes first. Judgment is built from reps, and every unassisted first draft is one. Skip enough of them and the skill fades, first in the calls only you make, like which client to take or which hire to bet on. Prompting after you form a position avoids that.
How should leaders use AI without losing judgment?
Write your position before you prompt. Then use the tool as a sparring partner. Ask it to attack your argument, find the weak paragraph and offer the angle you missed, and keep what survives. Prompt first and the tool becomes the author while you become its editor.
What is a thinking rep?
One unassisted pass at a problem your name goes on. You sit with a blank page and commit to a position, why you hold it and what it costs. About twenty-five minutes, once a week, on real work such as a client note or a proposal argument.
