You Approved It. But Did You Decide?
Five evaluators read the same AI-generated summary before scoring a tender, and their scores come out remarkably similar. Did they each decide, or did one AI interpretation shape five opinions? This episode looks at Anthropic's October 2026 study, in which analysts followed an AI agent's randomly assigned preference 86% of the time, and what that finding does and doesn't tell us. It explains why a questionable assumption is harder to spot than a factual error, what procurement's practice of individual scoring before consensus can teach other functions, and one practice to test on important decisions: View Before Review. The tender panel and manufacturer examples in the episode are hypothetical.
Imagine five professionals evaluating bids for a major contract. Before anyone records their score, they read the same AI-generated summary.
It makes a convincing case for one supplier. By the time the panel meets, their scores are remarkably similar.
That could be good news, or it could mean something else. Did five people independently reach the same decision? Or did one AI interpretation shape five opinions?
This is an imagined scenario, but the question matters anywhere AI supports important decisions.
You approved it, but did you decide? In my first episode, I argued that as AI takes over more analytical work, human value would increasingly lie in questioning assumptions and exercising judgement.
I still think that's important, but new research made me question something I had taken for granted.
What if AI influences our judgement before we even realise there is a decision to make?
On the 27th of October, Anthropic published a study involving 50 professional analysts using an AI agent.
The analysts were helping a fictional farming cooperative decide whether to expand or discontinue an advisory program for farmers. To make that decision, they first had to choose how to measure success.
Should they look at how much farmers produce from their land or how much they produce for every dollar spent?
Both approaches were reasonable, but they could lead to different conclusions. But here is what the analysts didn't know. The researchers had randomly instructed AI to favour one of the options. It was told to make the strongest case the data allowed without misrepresenting the results.
Across four analytical choices, the analysts followed the AI's preferred option 86% of the time.
If those randomly assigned preferences had no influence, you would expect agreement closer to 50%. Now, there is an important limitation.
This was a fictional task using one AI model, and the researchers deliberately strengthened its preferences.
So the 86% doesn't tell us how often this happens in everyday work.
And there was another interesting finding from this same experiment. The researchers also looked at 38 instances where analysts had already expressed their preferred option before receiving the AI's recommendation.
When the AI disagreed, they changed their minds 60% of the time. But when AI agreed, they changed their minds just 6% of the time.
This was a small number of cases, so we need to be careful about drawing broad conclusions. But it raises an important question. Were they changing their minds because the AI presented better evidence? Or because its arguments sounded more convincing?
And think about why this is hard to detect. If AI gets a formula wrong, we can check the numbers. If it misreads a contract clause, we can go back to the document.
But sometimes, the issue isn't a factual error. It's the judgement behind the recommendation. Which measure matters most, which risk deserves more weight, which supplier should make the shortlist.
Each option might be reasonable, but the way AI presents those choices can influence the final decision.
The calculations could be correct, but what if no one questioned assumptions behind them?
There is a useful example of this in procurement. When evaluating tenders, panel members can first review and score the bids independently before coming together to compare their assessments and agree on final scores.
This is also the approach outlined in South Australia's Government Procurement Guidelines and there is a good reason for it. But why does that sequence matter? Because each person brings a different perspective.
An engineer might spot a technical weakness. Finance might question a cost assumption. And procurement might identify a commercial risk in the supplier's proposal.
That's the real value of having an evaluation panel. It's not just about reaching agreement. It's about challenging each other's assumptions before making a decision. Now imagine what happens if everyone reads the same AI-generated recommendation before they have formed their own opinion.
They might all arrive at the same conclusion, but is that because they independently assessed the evidence, or because the AI influenced how they looked at it?
And here is the important distinction. The AI doesn't necessarily have to be wrong for this to become a problem.
The risk is that we lose the independent perspectives the panel was supposed to bring together, and this goes well beyond procurement.
Think about a CFO reviewing an AI-prepared investment proposal, or a risk executive assessing AI-recommended controls, or a supply chain leader deciding whether to change inventory levels based on an AI forecast.
In each case, AI can provide valuable analysis, but someone still needs to challenge the assumptions, weigh the trade-offs, and take responsibility for the decision.
Let me show you how the problem could play out. Let's imagine a manufacturer that buys 100,000 electronic sensors a year from a supplier paying $50 per sensor.
An AI sourcing assistant identifies another supplier offering compatible sensors at $47 each and recommends shifting 40% of the orders across.
On price alone that looks like a saving of $120,000 a year, with the added benefit of relying less on a single supplier.
Sounds like a good deal, right? But here is what the initial recommendation might have overlooked.
The existing contract includes a price increase if the manufacturer reduces its orders below 80,000 units a year. The new supplier also has longer delivery times, which means holding more stock, add extra freight and potential quality costs, and the economics start to change. There is also a one-off cost to qualify the new supplier and make sure the sensors meet the required standards.
In this example, once we account for the price increase on the remaining orders along with additional freight, inventory and quality costs, that apparent savings disappears. Instead, the business would face around $44,000 in additional annual costs.
And that's before considering the one-off cost of qualifying the new supplier or the potential benefits of reducing supply disruption.
So does that mean the AI's recommendation was wrong? Not necessarily. Having a second supplier could help the manufacturer keep production running if the existing supplier experiences a major disruption and that protection might be worth paying for. Or perhaps moving just 20% of the orders would offer a better balance between cost and resilience without triggering the existing supplier's price increase.
But a smaller allocation might also provide less protection. And that's where the real decision lies.
How likely is a disruption? How much would a second supplier reduce its impact?
And how much should the business be willing to pay for that protection?
The human category manager might have overlooked something too. Neither the human nor the AI is automatically right. What matters is making the assumptions visible, challenging them and understanding the trade-offs before making a decision.
So how do we do that in practice? Here is one approach I would suggest organisations test when making important decisions that require judgement.
I call it View Before Review. First, before reading the AI's recommendation, record a short initial view. What would you choose? What's your main assumption? And what evidence would change your mind? Second, ask the AI for its analysis, the assumption behind its recommendation and the strongest reasonable case for a different option.
Not just a polished recommendation. Third, compare the positions. Where do they differ?
Which facts can be checked and which assumptions need a decision-maker's judgement? And fourth, record the final choice, why you made it, and how you will review the outcome.
That final step is essential. Remember the Anthropic study? Even people who had already expressed a preference sometimes changed their minds when the AI disagreed.
A first view isn't a shield. You still have to ask yourself, what changed my mind?
Was it new evidence? A better argument? Or simply the confidence of the system presenting it?
And another study explored exactly that. Does it make a difference if we form our own opinion before seeing what AI recommends?
In 2026, researchers asked trainee teachers to assess classroom situations with the help of AI.
But sometimes, the AI's recommendations were deliberately misleading. And here is what they found. When the teachers formed their own opinion first, they reached the answer considered correct by experts about 54% of the time.
But when they saw the AI's recommendation first, that dropped to 37%. Interestingly, when the AI's recommendation was correct rather than misleading, both groups performed at about the same level. The researchers couldn't find a clear difference between them. Now, these were simulated classroom situations, not real business decisions, so we can't assume the same results would apply everywhere. But it suggests something worth considering. Forming our own view first may help us recognise misleading advice while still allowing us to benefit from AI when it gets things right.
Of course, I wouldn't use this approach for every email summary, spreadsheet check, or routine decision, and I certainly wouldn't delay an urgent reversible action just to complete another form.
The point isn't to slow everything down, it's to make a space for independent thinking when the decision really matters.
But there is one challenge we need to take seriously. What if the AI is actually better than us? And sometimes it might be. Human judgement comes with its own biases. We can favour familiar suppliers, be overly confident in our experience, or hold on to forecasts we've already made. And for some decisions, like forecasting demand or predicting risks, AI may actually make more accurate predictions than we do.
So the answer isn't to defend human judgement at all costs. It's to understand when AI improves our decisions, when it doesn't, and why. For finance, that might mean checking whether an AI-assisted investment forecast proved more accurate than the project sponsor's original assumptions. For risk, it could mean reviewing why a risk was accepted, and whether that decision still makes sense as circumstances change.
And for supply chain, it might mean testing whether human adjustments to AI forecasts improved accuracy or made it worse. Different functions, but the same underlying question: are we genuinely making better decisions? Or simply making them easier to approve? Because approval is a process step. Independent challenge is a capability. And they're not the same thing.
Challenging AI doesn't mean refusing to change your mind. It means understanding what changed it, and why. Now, think back to those five tender evaluators. Imagine they each assess the bids independently before seeing the AI's recommendation.
Then they compare their assessments with the AI's analysis, challenge the differences and revise their scores where the evidence supports it.
They might still recommend the same supplier, but this time, they have tested the reasoning rather than simply agreed with a recommendation.
It doesn't guarantee a better outcome, but it makes the decision easier to explain, review and learn from. So the next time someone tells you an AI-enabled process is safe because there is a human in the loop, ask yourself, did that person genuinely challenge the recommendation or simply approve it? Because approving a decision and genuinely deciding aren't always the same thing.
