Critical Thinking and Confirmation Bias: The Habit of Just Consuming

Critical thinking, confirmation bias, and why we consume instead of think
Richard Golian

Hi, I am Richard. On this blog, I share thoughts, personal stories, findings and what I am working on. I hope this article brings you some value.

Lately, I have been noticing something new in job interviews. Candidates come in "prepared," but in a strange way. They get an hour to prepare, and they use it to pull as much information as possible from ChatGPT. Then they confidently present it to me. They mention a metric that, according to them, is crucial for evaluating advertising performance. But when I ask them what the metric actually tells us, they do not know. They have no idea how to calculate it.

I have never had so many interviews where I had to teach candidates the meaning of a key metric in online advertising. Never.

But let us be clear. This is not the same as when calculators were introduced. You can work with someone who does not understand logarithms. But you cannot seriously discuss or collaborate with someone who does not even understand which two numbers to divide to get meaningful insight in advertising. You just cannot.

And it is not just interviews. More and more, I feel like real thinking is fading away. People do not form their own ideas anymore; they just adopt prepackaged opinions that flood them from all directions. Information is instantly accessible, and it requires no effort from us.

Many believe they have broad knowledge because they follow multiple sources. But I have my doubts. Real thinking takes effort. Thinking deeply about something means spending time questioning, challenging established views, and arriving at your own conclusions.

Cognitive Bias and Why We Just Consume

What is a cognitive bias? A cognitive bias is a systematic error in our thinking, a mental shortcut that lets us reach a conclusion without the effort of full reasoning. What I keep noticing is the same pattern repeated everywhere. We follow many sources, yet we mostly take in what confirms what we already believe and mistake that recognition for understanding. That is confirmation bias, and it is what allows a person to consume opinions instead of forming them.

One of the strange things about our time is that even criticism has turned into a kind of consumption.

I see it clearly in debates on serious social issues – take Covid, for example. Entire crowds jumped into criticising one expert opinion or another, often with great confidence, while having only a shallow understanding of the topic.

They felt the need to criticise, to take a stand – but without having arguments of their own. So they just adopted someone else’s critical take.

We repeat another person’s objections and feel like we have been thinking. But what we have really done is just accepted a different ready-made opinion. That is not critical thinking.

I get the sense it is connected to a fear of independent thinking.

Summary

In interviews lately, candidates arrive looking well prepared. They have pulled metrics from ChatGPT but cannot tell me what those metrics mean. I have never had to teach so many people the basics of their own field. Real thinking is fading. The cure is simple, and uncomfortable. Make time to think. Question the ready-made opinion.

Common questions on this article's topic

What is a cognitive bias?
A cognitive bias is a systematic error in how we think, a mental shortcut that produces a conclusion without the effort of full reasoning. In the article I describe a version of this that has become a habit. We follow many sources but absorb what confirms what we already believe, and we mistake that recognition for understanding. The bias is not a lack of intelligence. It is the path of least effort, and consuming ready-made opinions is the easiest path of all.
What is confirmation bias?
Confirmation bias is the tendency to notice, accept and remember information that supports what we already think, while quietly filtering out whatever does not. In the article this appears as people who believe they have broad knowledge because they follow multiple sources, yet only ever reinforce their existing views. Following many feeds is not the same as thinking. If every source you consult tells you what you already believe, you are consuming confirmation rather than testing your ideas.
What are some cognitive bias examples?
Common cognitive bias examples include confirmation bias, which is favouring information that supports your existing view, conformity, which is adopting the opinion of the group to avoid standing out, and the bandwagon effect, which is believing something because many others appear to. The article describes a related pattern in which people adopt someone else's criticism, repeat it, and feel as though they have reasoned. The Asch conformity experiments and the Noelle-Neumann spiral of silence describe the same pull. The form of the opinion changes, but the passivity remains.
How is AI affecting the quality of job candidates?
In the article, a new pattern is observed in interviews: candidates arrive prepared with AI-extracted metrics and terminology but cannot explain what the numbers actually mean or how to calculate them. This is not the same as using a calculator. You can work with someone who does not understand logarithms, but you cannot collaborate with someone who does not understand which two numbers to divide to get a meaningful insight. The fundamental understanding is missing.
What is the difference between consuming information and actually thinking?
In the article, the distinction is clear: real thinking takes effort. It means spending time questioning, challenging established views, and arriving at your own conclusions. Consuming information means passively absorbing pre-packaged opinions that require no effort. Many people believe they have broad knowledge because they follow multiple sources, but following is not the same as thinking. The difference lies in whether you are creating understanding or merely receiving it.
How has criticism itself become a form of consumption?
In the article, this is illustrated through social debates, like those around Covid, where crowds confidently criticised expert opinions without having arguments of their own. They adopted someone else's critical framework and felt like they had been thinking. But repeating another person's objections is not critical thinking. It is just accepting a different ready-made opinion. The form changes but the passivity remains.
Why are people afraid of independent thinking?
Because real thinking carries social risk. In the article, this is connected to a fundamental dynamic: arriving at unpopular conclusions may lead to being misunderstood, disagreed with, or socially excluded. This is consistent with Asch's conformity experiments, where 74% of participants conformed to incorrect group opinions, and Noelle-Neumann's spiral of silence theory, where fear of isolation drives people to suppress minority views. Thinking outside the box is genuinely risky.
Does the speed of the internet make deep thinking harder?
Yes. In the article, the observation is that instant reactions are expected, and being slow means being outdated and therefore irrelevant. By the time someone reaches their own analysis, the internet has moved to a new topic. Research supports this: heavy smartphone users show diminished ability to interpret deeper meaning, and attention-capturing digital interfaces promote heuristic processing over sustained analysis. Speed and depth are in tension.
What can individuals do to think more independently?
In the article, the steps are deliberately small: give yourself time to think instead of reacting immediately. Do not rush to form an opinion just to have something to say. Ask yourself where your thoughts really come from. Are they truly yours? These are not dramatic interventions but a conscious decision to step out of the pattern of consuming and repeating, even if it feels uncomfortable at first.

I Ran Object Detection on My Laptop, and Saw Everything Is Possible

A few weeks ago I installed a small local AI model on my laptop that watches a live camera feed. I turned the webcam on in the dark, and in near total darkness it recognised me and the objects in the room. That such things exist, I have known for a long time. What opened my eyes was the accessibility. I installed it in one prompt, free, and it runs entirely on my machine, sending data nowhere.

Is AI Making Us Dumber?

I have conducted roughly one hundred and fifty practical interviews over the past four years. Fifty for data specialist roles. A hundred for advertising and performance marketing specialists. Almost every one of them involved sitting down with a candidate over a practical task, something close to a real problem we actually need to solve at the company. Not theory. Not trivia. Applied problem-solving. Over time, I started noticing a pattern.

Fable 5 vs Opus 4.8: the cheaper model won

The same task, two models. Fable 5 against Opus 4.8. On paper Fable is the better model, with a larger context and stronger specs. And still it lost. Opus handled the task with a single round of checking for 721,000 tokens, while Fable needed nine rounds and burnt through 2.78 million tokens. The difference was not in the model, but in how I set the task. And I know it, because I measured it.

Which Work Will AI Not Replace?

Seventy per cent. That is where the first AI output begins, even when you give it the full company context and the best examples from the past. We are talking about the kind of output that cannot be defined programmatically. It is more complex. Often it is creative work. On one repeated type of output I reached eighty per cent within a week. Every further percentage point is harder than the one before.

What is the dead internet theory? Will we return offline?

For a long time we treated the internet as the main road. The place where work and relationships happen. Yet most of what we see on it today is, or soon will be, AI-generated: text, images, profiles and comments. The internet is turning into an online game full of bots, where you cannot be sure that a human is on the other side of anything. So I ask: was the online world the main road, or only a temporary detour that part of us will return from, back offline?

I know the other side too: professionals who automate everything that can be automated.

Europe Is Not Ready for Drone Warfare

Europe does not have the capacity to face a full-scale, mass drone war of the kind we see in Ukraine.

Rearmament plans exist, but they are being carried out slowly.

Can AI Replace Human Judgement?

AI produces the graphic, the newsletter and the product page faster than a person. What is left for the one who used to do it is the judgement, knowing whether the output is good.

What Determines a Stock Price?

In April, in the first part of this series, I wrote about an AI prediction system I had started building on my own machine. At the time the software was a few hours old and the prediction record was empty. The record since then has shown one thing: the system does not yet understand the market it is being asked to forecast. It can pull macro context, book value, earnings. But it cannot put those together into something that helps it understand the price.

Where the Money Goes When AI Takes the Work: Mapping the AI Economy

Prague, 13 May 2026. On my way to work I started thinking about something that stayed with me for days. If most routine work on a computer disappears in the next ten years, and a large share of repetitive manual work disappears with it, what happens to the flow of money? Who pays whom for what? Which economic layers will exist, how large will they be, and what relationships will run between them? This is the six-layer map I sketched as an answer.
