Critical Thinking Skills: Definition + 50 Examples

1. What Are Critical Thinking Skills?

Critical thinking is the work you do between receiving information and acting on it. In an ordinary week that includes reading a report and asking what was counted, hearing two accounts of the same incident and working out where they diverge, noticing that a recommendation rests on a figure nobody has checked, or realizing that the question you were asked cannot be answered with the information available.

A practical way to describe the process is a loose sequence: clarify the question, gather relevant information, evaluate what that information is worth, question the assumptions behind it, compare competing explanations, examine the reasoning, reach a conclusion proportionate to the support, and update when the picture changes. This is a useful editorial model rather than a mandatory universal sequence. People move back and forth between stages constantly, and for a small question most of it happens in a few seconds without being named.

It is equally useful to be clear about what critical thinking is not. It is not criticizing everything, being negative, arguing for its own sake, distrusting people by default, automatically rejecting or automatically accepting authority, being cynical or contrarian, being unable to decide, or overthinking small reversible matters. It is not a measure of intelligence, it does not require knowing everything, and it does not mean always being right or never changing your mind. Finding flaws in colleagues is not critical thinking, and neither is treating other people's opinions as worthless.

2. Critical Thinking Skills Definition

Several nearby terms get used interchangeably at work, which is part of why discussions about evidence go in circles. The table below separates them with concrete examples. None of these categories are rigid, and the same piece of work can involve most of them within an hour.

One distinction in that table is worth drawing out, because it causes a lot of confusion in job descriptions: a tool is not a thinking skill. A spreadsheet, a decision matrix, a template or a checklist can structure your reasoning and make it visible to others, but none of them decide whether the numbers going in mean what you think they mean. Tooling belongs with hard skills; the judgment applied to its output does not.

3. 50+ Critical Thinking Skills Examples

80 distinct skills, grouped into ten areas. They are deliberately separate abilities rather than synonyms for each other — clarifying a question, checking an assumption and calibrating a conclusion are different activities that people are good at to different degrees. Few roles need all of them, and most people are noticeably stronger in some groups than others.

4. Why Critical Thinking Skills Matter at Work

Most workplace information arrives already interpreted. A report comes with a headline, an incident comes with an explanation, a proposal comes with a rationale. Critical thinking is what lets you tell how much of that is established and how much is being asserted — which matters because the interpretation, not the underlying information, is usually what gets acted on.

• • It can help clarify ambiguous claims before work is done on the wrong question.
• • It can reduce the chance of acting on an assumption nobody has checked.
• • It can surface missing information early, while it is still obtainable.
• • It can make conflicting accounts comparable instead of leaving them as a dispute.
• • It can help you communicate uncertainty accurately, so others can weigh your input properly.
• • It can help distinguish stronger from weaker support when two proposals both sound convincing.
• • It can help you notice when a question needs expertise you do not have.
• • It can make revising a conclusion a normal part of the work rather than an embarrassment.

These are possibilities, not promises. Careful reasoning does not guarantee correct decisions, and it cannot compensate for missing information, absent authority or a question that requires qualified expertise. Nobody should claim that a thinking habit produces promotions, higher pay or measurable productivity gains, and this guide does not. If you are looking at how skills relate to earnings, the honest route is comparing published wage data for occupations rather than attributing pay differences to a personal quality — our salary comparison tool uses official U.S. wage data for that.

5. Types of Critical Thinking Skills

Grouping critical thinking into types is an editorial convenience, not a scientific classification. The groups below overlap heavily — evaluating a source is part of evaluating evidence, and checking an assumption often surfaces an alternative explanation. They are useful mainly for working out where your own practice is thin.

Someone can be strong in one group and weak in another. A person who evaluates evidence rigorously may still answer the wrong question; a person who clarifies beautifully may state conclusions far more firmly than the evidence allows. Looking at the groups separately is more useful than asking whether you are a good critical thinker overall.

6. Clarifying Questions and Claims

An unclear question reliably produces a misleading answer, and the answer will look perfectly sound. If someone asks whether sales are down, the honest first move is to establish whether they mean units or revenue, over which period, for which products, and compared with what. Those choices, not the analysis, will decide the answer.

• • What exactly is being claimed, stated in one sentence?
• • What question are we actually answering, and what decision depends on it?
• • Which terms need defining because different people are using them differently?
• • What is the scope — which period, which cases, which population?
• • What would count as relevant information, and what would not?
• • Is there an answer already embedded in the way the question was asked?

Clarification is cheap and rarely regretted. One sentence back to the requester — “so you want to know whether the delay was caused by the vendor, for orders placed after March, using the receiving records?” — takes a minute and often changes the whole task. It also surfaces disagreements that would otherwise appear at the end, when the work is already done.

7. Distinguishing Facts From Interpretations

Most workplace disputes about evidence are actually disputes about interpretation, in which both sides believe they are describing facts. The distinction is easiest to see in a concrete illustrative example:

The observation does not establish the interpretation. The same three timestamps are equally consistent with the cutoff not being visible on the mobile form, with a time zone difference, with the requests having been sent earlier and queued, or with three unrelated individual circumstances. The interpretation may still turn out to be correct — the point is that it has not yet been shown, and once it is written into the summary everyone downstream will treat it as what happened.

Interpretations are not the problem. Work would be impossible without them, and experienced people interpret quickly and often accurately. The skill is keeping them labelled: writing “three requests arrived after the cutoff; the most likely explanation is the mobile form, which we have not checked” gives the reader both the record and your reading of it, and lets them disagree with the second without disputing the first. Watch for words that assert intent — ignored, refused, failed, neglected — because they carry an explanation inside what looks like a description.

8. Gathering Relevant Information

Gathering information is a filtering task, not a collecting task. The useful questions are which information would actually bear on the claim, whether what you have covers the period and cases in question, whether it is current enough to matter, what context is needed to read it properly, and what is missing.

More information is not automatically better. Irrelevant material dilutes attention, makes a thin case look substantial, and delays a conclusion that the existing evidence already supports. A conclusion built on three directly relevant records is usually stronger than one built on thirty loosely related ones.

Access matters too. Gather only what you are authorized to see, and request anything else through the proper route. Working around a restriction to satisfy your own curiosity about a question creates a compliance problem regardless of how good the reasoning behind it was, and in areas such as personnel records, customer data or security logs it can be a serious one.

9. Evaluating Sources and Evidence

Source evaluation is contextual. There is no list of sources that are always reliable and sources that never are — the question is what this source is in a position to know about this particular claim. A frontline colleague may be the best available source on what customers say and a poor one on why a system behaves as it does; a vendor may have accurate performance figures that simply do not apply to your setup.

Two habits are worth resisting. The first is treating a conflict of interest as disqualifying: interested parties are frequently right, and the correct response is to examine their support more carefully rather than discard their claim. The second is treating corroboration as automatic confirmation — three documents citing the same original figure are one source, not three.

Evidence evaluation asks a narrower question: how well does this particular information support this particular claim? Relevance comes first — evidence about something adjacent is not weak evidence, it is evidence for a different claim. Then directness, quality, completeness, the context in which it was produced, consistency with other information, its limitations, and whether there is competing evidence that has been left out. A figure with nothing to compare it against usually cannot support a claim about change, and examples chosen because they were memorable rarely tell you what is typical.

Claim and evidence check

Claim (one sentence):
Who is making it, and what are they positioned to know:
What is offered as support:
How directly does that support bear on the claim:
What it does not cover (period, cases, scope):
Alternative explanation that fits the same information:
What would make this claim stronger:
Conclusion I can responsibly state right now:

Source evaluation note

Source:
Where the information originated (not who forwarded it):
Relevant expertise for this specific claim:
Evidence or method provided:
How recent, and does recency matter here:
Interests or incentives worth noting:
Independent corroboration available:
What this source could not have known:
How much weight I am giving it, and why:

10. Identifying Information Gaps

A conclusion drawn only from what happened to be available takes the shape of the available data. Naming what is missing is part of the analysis rather than a caveat appended to it, and it is often the single most useful contribution in a discussion where everyone is arguing from the same partial picture.

• • What do we actually know, as distinct from what we have inferred?
• • What do we not know?
• • Which of the unknowns would materially change the conclusion?
• • Can the missing information reasonably be obtained, and at what cost?
• • Does the decision have to happen before the uncertainty can be resolved?
• • If it does, what is the most defensible conclusion given what is available?

The fourth and fifth questions do most of the work. Many gaps are real but immaterial, and chasing them is a way of avoiding a conclusion. Others are decisive and obtainable in an afternoon, in which case the analysis should wait. And some decisions genuinely cannot wait — in which case the right output is a conclusion stated with its limits attached, not an indefinite delay.

11. Checking Assumptions

Everyone works on assumptions; there is no version of this where you verify everything. The skill is noticing which ones you are relying on, judging which would change the conclusion if they were wrong, and checking those. The others can be stated and left alone.

Assumptions about intent deserve particular caution. Concluding that someone acted carelessly, deliberately or in bad faith is an inference about a person's mental state, and it is almost never checkable from the records in front of you. Describe the behavior, ask the person where you reasonably can, and leave motive out of the written conclusion.

Assumption check

Assumption:
Type (causal / timing / user / resource / process / authority / intent / urgency / feasibility):
Why it matters to the conclusion:
Has it been verified in this instance:
How it could be checked, and at what cost:
What changes if it turns out to be wrong:
Decision: check it / accept it and flag it / set it aside as low impact

12. Considering Alternative Explanations

The first explanation that fits the facts tends to become the only one considered, and everything discovered afterwards gets read as support for it. Generating one plausible alternative is a cheap correction: it does not have to be convincing, it only has to keep the question open long enough for contrary information to register.

There is no requirement to enumerate alternatives endlessly. Two or three well-chosen ones, compared on how much of the observed information each accounts for, is usually the productive stopping point. The goal is to avoid premature closure, not to reach paralysis — an analysis that never settles on anything is as unhelpful as one that settles immediately.

13. Comparing Information and Perspectives

When two accounts conflict, comparing them properly means finding the specific point of divergence rather than choosing between the narratives. Set them side by side on what each actually observed, what each is inferring, what evidence each rests on, what each assumes, what context each sits in and what, if anything, each party has at stake.

Perspective is genuinely valuable information. The people doing the work often know things the reporting cannot show, and asking them is frequently the fastest route to the missing variable. But a perspective is not the same as evidence for a factual claim. Someone's well-informed impression that a process has got slower is a strong reason to look; it is not, by itself, a finding that the process has got slower.

The corresponding error is false balance — presenting two positions as equally supported because both were sincerely held. Not every view carries the same evidentiary weight, and pretending otherwise is a distortion in its own right. Weigh views by the support behind them, while still hearing them. The skills of drawing out what people know and handling the disagreement that follows sit in communication skills and interpersonal skills.

14. Evaluating Reasoning, Correlation and Causation

Evaluating reasoning at work does not require formal logic. It requires laying out the argument in parts and looking at the joins: what is the conclusion, what reasons are given, what evidence sits behind those reasons, what is assumed, what is missing, and is there a step where the argument travels further than its support carries it.

• • Does the conclusion follow even if every stated reason is true?
• • Is there an unstated premise the argument depends on?
• • Has “could have” quietly become “did”?
• • Are two claims in this document inconsistent with each other?
• • Is the conclusion being used, somewhere, as its own support?
• • Do the numbers, dates and narrative actually agree?

Naming reasoning problems can help, but cataloguing fallacies is not the point and deploying the names in a meeting rarely improves anything. Describing the specific gap — “this assumes the two teams counted the same way” — does more than labelling it.

Cause and effect deserve a note of their own, because the error is so common and the overcorrection almost as common. Two things occurring together does not by itself establish that one caused the other. It also does not mean the pattern is meaningless: co-occurrence is often the first useful signal you have, and the right response is to investigate rather than to dismiss. Possible explanations for a pattern include a causal relationship, causation running the other way, a third factor driving both, coincidence within normal variation, differences in which cases were included, and changes in how something was measured or defined. Working through those candidates briefly is usually enough for workplace purposes; establishing causation properly is a specialist exercise that most workplace evidence cannot support.

15. Recognizing Uncertainty

Uncertainty is not the same as ignorance. Knowing precisely which part of a picture is unsupported, and why, is an informed position — and it is far more useful to a decision-maker than a confident summary that hides the same gap.

These are editorial communication categories, not formal probability levels. Attaching invented percentages to workplace judgments — “I am 80% confident” — usually adds false precision rather than clarity, unless the number comes from something that was actually measured. Plain language about what is established, what is likely and what is not known communicates more honestly.

16. Reaching Proportionate Conclusions and Updating Them

A conclusion should be no stronger than the support behind it. This is mostly a matter of wording, and the difference between two versions of the same sentence can be the difference between an accurate summary and an overstatement that drives a decision.

This illustrative pair is not an argument for hedging everything. Over-qualification is its own failure: a summary in which nothing is stated plainly gives the reader no information and quietly transfers the judgment back to them. Where something is established, say so plainly. Reserve the qualifiers for the parts that need them, and make clear which parts those are.

Conclusions should also be revisable. New evidence appears, an earlier figure is corrected, an assumption fails, the context changes, or someone with relevant expertise points out what the analysis could not see. Changing your view in any of those circumstances is good reasoning. Consistency is not inherently superior to revision, and a position held unchanged through new information is not thereby more rigorous. The useful habit is to state in advance what would change your mind — then, when it happens, saying so directly rather than letting the old conclusion quietly stand.

17. Critical Thinking at Work

Fifteen illustrative situations across different kinds of workplace, with the skill each calls on and what applying it can look like. These are examples of an approach, not recommendations about any specific case — and none of them involve reaching conclusions that require professional expertise.

A theme runs through all fifteen: the first move is almost never producing an answer. It is establishing what is being claimed, what the information actually shows, and what has been assumed. Where a situation involves safety, legal exposure, privacy, security, regulatory compliance, medical questions, significant financial matters or conduct issues such as harassment or discrimination, the appropriate critical-thinking action is usually to route it to the qualified person or defined channel. Recognizing the limits of your own expertise is judgment, not deference.

18. Critical Thinking vs. Problem Solving

These overlap constantly and are not the same thing. Critical thinking is mainly concerned with evaluating information: what is being claimed, what supports it, what has been assumed and how strongly a conclusion is held. Problem solving is broader and action-oriented: recognizing and defining an issue, investigating possible causes, generating responses, choosing or escalating, implementing and checking whether anything actually changed.

In practice critical thinking supports problem solving throughout, most visibly when checking assumptions about causes and weighing evidence about whether a fix worked. For the full treatment of defining problems, investigating causes, comparing responses, escalating and evaluating results, see our guide to problem-solving skills, which is the companion to this one.

19. Critical Thinking vs. Decision Making and Analytical Skills

Decision making is about choosing and committing. It operates under constraints critical thinking does not resolve: a deadline, a budget, the limits of your authority, the risk the organization is willing to take, and the fact that the information will not be complete. A well-reasoned analysis that never converges on a choice has not made a decision, and many decisions must be made while the evidence is still thin. Critical thinking improves the input to a decision; it does not make the decision for you.

Analytical skills lean toward breaking information apart, structuring it, working with data and finding patterns. Critical thinking leans toward judging assumptions, evidence, reasoning and the support behind a conclusion. The overlap is large — segmenting a dataset is analytical work, asking whether the segments were defined in a way that manufactures the pattern is critical thinking — and most roles that want one want both.

Where these sit in the wider skills picture: critical thinking is usually classed with soft skills, it is highly transferable across roles, and it works alongside the hard skills that produce the information being evaluated. Applying it to work that has to be organized across people and deadlines brings in management skills, leadership skills and time management skills — not least because evaluation takes time that has to come from somewhere.

20. Critical Thinking and Cognitive Bias

People are subject to recurring tendencies in judgment, and a few are worth knowing about because they describe patterns most of us recognize in our own work. Confirmation bias describes the tendency to notice and weight information that fits an existing view. Anchoring describes the influence an initial figure or framing can have on later judgments. Availability effects describe how easily recalled examples can feel more representative than they are. Sunk-cost thinking describes the pull of past investment on a decision that should turn on future value.

The cautions matter as much as the concepts. Knowing the name of a bias does not establish that it affected a particular person or a particular decision, and using these terms to explain a colleague's view is a way of dismissing an argument without examining it. No checklist eliminates bias; people who think carefully are not thereby free of it, and confidence in your own objectivity is not evidence of it. The practical use of these ideas is inward and modest: noticing that you have only looked for confirming information, or that a first estimate is still framing the discussion, and then going and checking something.

21. How to Identify Your Critical Thinking Skills

Most people cannot answer “how good is your critical thinking?” in any useful way, and the answer would not be worth much if they could. A better route is working backwards from specific situations where the information was incomplete or contested, and naming what you actually did.

1. 1. Review situations where the information was incomplete, conflicting or contested rather than situations that went smoothly.
2. 2. Identify the question or claim that was actually at stake in each one.
3. 3. Identify what information you gathered, and what you chose not to rely on.
4. 4. Identify the assumptions you checked, and how you checked them.
5. 5. Review which alternative explanations you considered before settling.
6. 6. Identify how you judged whether the evidence supported the conclusion.
7. 7. Review whether your conclusion changed, and what changed it.
8. 8. Translate each behavior into a specific, named skill rather than the phrase “critical thinking”.

Eight illustrative mappings from behavior to named skills. These examples are fictional and are here to show the translation, not to describe real cases or outcomes.

Turning that list into something you work on deliberately fits naturally into a professional development plan or an individual development plan, and into the longer view set out in career planning and career goals.

22. Critical Thinking Skills for a Resume

Critical thinking is one of the least useful phrases to list and one of the more convincing things to show. Almost every applicant claims it, the claim carries no information, and a reader has no way to distinguish between two people who both wrote it. A short description of what you actually checked does the work instead.

Keep the examples true to your own work and avoid attaching invented figures; a percentage nobody measured is easy to ask about and hard to defend. For where skills belong on the page, how many to include and how to phrase them, see skills for a resume, resume examples and resume summary examples.

Resume lines that show critical thinking (adapt to your own work)

Instead of: "Excellent critical-thinking skills."

Compared conflicting customer reports with account records, identified the missing
information and documented the evidence supporting the recommended next step.

Reviewed a recurring reporting discrepancy, established that two teams were using
different definitions, and proposed a single definition adopted across both.

Assessed vendor performance claims against our own usage conditions and flagged
where the cited results did not apply to our setup.

Revised a project recommendation after new schedule data showed the original
assumption about dependency timing was incorrect.

23. Critical Thinking Skills in Interviews

Interview questions about critical thinking are usually asking for a process, not a result. What was unclear, what did you check, what did you assume, how confident were you, and what would have changed your answer. An example where you revised your view after new information often lands better than one where you were right from the beginning — it shows the evaluation actually happened.

Four fictional examples, written to show the structure: situation, the question or uncertainty, the information considered, the reasoning, and the conclusion or lesson. Use them as a shape for your own experience rather than as answers to reuse, and see how to prepare for a job interview for the wider preparation.

Four interview answers built on evaluation, not labels
(structure: situation - question or uncertainty - information considered - reasoning - conclusion)

1. Conflicting information
"Two teams reported different completion rates for the same work. Rather than
picking one, I checked what each was counting and found one included cancelled
items. I proposed a shared definition and reran both figures."

2. An assumption that proved wrong
"We had been treating a recurring delay as a supplier issue. I checked the
receiving timestamps and found most shipments arrived on time but waited for an
internal check. I raised it with the process owner rather than the supplier."

3. Insufficient evidence
"I was asked whether a change had improved retention. The period was short and a
pricing change overlapped it, so I said the data was consistent with improvement
but could not establish it, and set out what a cleaner comparison would need."

4. A recommendation changed after new information
"I recommended one vendor, then learned their reference deployment was a tenth of
our volume. I withdrew the recommendation, explained why, and asked both vendors
for comparable references."

24. How to Improve Critical Thinking Skills

Improvement here comes from applying a small number of habits to real work, repeatedly, rather than from studying reasoning in the abstract. The ten steps below are ordered as a rough sequence, but each one is useful on its own and none of them require anyone else's cooperation to start.

1. 1. Clarify the question before answering it

   Write the question or claim in one sentence and check it with whoever raised it. A surprising share of wasted analysis is a careful answer to a question nobody asked.

2. 2. Separate observations from interpretations

   Split your notes into what was recorded and what you take it to mean. Keep the two visibly apart in anything you send on.

3. 3. Identify what information is missing

   List what you do not know, and mark which items would change the conclusion and which are merely absent.

4. 4. Make your assumptions explicit

   Write down what you are treating as true without having checked it here. Most of these are fine; you only need to test the consequential ones.

5. 5. Ask what evidence supports the claim

   For each significant statement, ask what it rests on, how directly, and whether the support is being asserted or shown.

6. 6. Consider at least one plausible alternative

   Force one competing explanation into the discussion, even a weak one. The point is to break the pull of the first account that fits.

7. 7. Match your confidence to the support

   Rewrite your conclusion so its strength fits the evidence — consistent with, suggests, indicates, establishes are not interchangeable.

8. 8. Seek relevant expertise when the question needs it

   Recognize where your judgment runs out. Medical, legal, safety, security, compliance and significant financial questions belong with qualified people, and routing them there is good reasoning rather than a lack of it.

9. 9. Review where your reasoning was wrong or incomplete

   Revisit a few past conclusions and ask what you missed. Reviewing your own work honestly does more for critical thinking than reading about it.

10. 10. Practise updating when information changes

    Say out loud what would change your mind, then follow through when it happens. Treating revision as normal makes it easier to do under pressure.

Two honest caveats. Progress is uneven and partly domain-specific: careful reasoning about material you know well does not automatically transfer to a subject where you cannot tell a strong source from a weak one. And there is no timeline on this — anyone promising a transformation in thirty days, a measurable jump in reasoning ability or a career outcome from a thinking course is selling something. What is realistic is noticing, over months, that you clarify questions earlier, state assumptions more often and overstate conclusions less.

25. How to Develop Critical Thinking Skills Through Practice

Practice works best on material you already handle. Ten short exercises, each with how to run it and where it has limits. Pick one or two that match the kind of information your role involves rather than attempting all of them.

None of this requires a course or a purchase, and none of it should involve taking on unpaid work to demonstrate the skill. Where formal development is available through your employer, career development programs covers how to evaluate what is on offer.

26. How to Demonstrate Critical Thinking Skills

Critical thinking is visible in artifacts and behavior, not in self-description. Twelve types of evidence that show it happened:

The same principle applies in performance reviews, promotion cases and written handovers: describe what you checked and what it changed. Avoid attaching figures to outcomes that were never measured — a fabricated metric undermines exactly the quality you are trying to demonstrate.

28. Common Critical Thinking Mistakes

Fifteen recurring errors. Several are overcorrections — the failure mode of trying to think critically rather than of not trying at all.

1. 1. Answering before clarifying the question

   The fastest way to produce a careful, well-evidenced answer to something nobody asked. One clarifying sentence usually prevents it.

2. 2. Treating an interpretation as a fact

   “Customers are ignoring the instructions” is an explanation of “three requests arrived after the cutoff”. Both may be reasonable; only one was observed.

3. 3. Treating confidence as evidence

   How firmly something is stated carries no information about how well it is supported — in either direction. Quiet uncertainty is not weakness and firm delivery is not proof.

4. 4. Relying on a single source without context

   One source is sometimes sufficient, particularly an authoritative record. The mistake is not noticing that you have only one, and not asking what it could not have known.

5. 5. Dismissing information solely because of perceived bias

   An interest in the outcome is a reason to check the support more carefully, not a reason to discard the claim. Interested parties are often right.

6. 6. Assuming more information is always better

   Irrelevant information does not strengthen a conclusion; it dilutes attention and can make a weak case look substantial.

7. 7. Not identifying what is missing

   A conclusion built only on what happened to be available inherits the shape of the available data. Naming the gaps is part of the analysis.

8. 8. Leaving assumptions implicit

   Unstated assumptions cannot be challenged, so they survive review unnoticed and reappear as the reason the conclusion failed.

9. 9. Considering no alternative explanation

   The first account that fits tends to become the only one considered. Generating one alternative is a small cost and catches a lot.

10. 10. Treating correlation as proof of causation

    Two things moving together is a reason to investigate. Saying so plainly is more useful than either asserting cause or pretending the pattern means nothing.

11. 11. Giving every perspective equal evidentiary weight

    Perspectives deserve to be heard; they do not all carry the same weight as support for a factual claim. False balance is its own distortion.

12. 12. Refusing to update a conclusion

    Treating consistency as integrity turns a first impression into a permanent position. Revising on better evidence is the skill, not the failure.

13. 13. Overthinking low-stakes questions

    Full evaluation of a reversible, minor decision costs more than being wrong about it. Proportion is part of judgment.

14. 14. Assuming skepticism is critical thinking

    Reflexive doubt is as unexamined as reflexive acceptance. The work is evaluating support, not withholding agreement.

15. 15. Using bias and fallacy labels instead of analysis

    Naming a bias or a fallacy can end a discussion without examining anything. It also tends to be aimed at people rather than at claims.
