How to Explain Your Thought Process Clearly

6 min read · IQ Tester

Here's how to explain your thought process clearly: say your answer first, then give your steps in order, then show how you checked it. That three-part structure (claim, steps, check) works for a math problem, an essay argument and a job or college interview question. Most people have good thinking; it just comes out in the wrong order.

If your reasoning is fine in your head but falls apart when you try to say it, IQ Tester checks whether putting reasoning into words is your weak spot and gives you a short daily drill for it: Find my weak spots.

Why good thinking gets lost

When a teacher writes "explain your thinking" on your test, or an interviewer says "walk me through how you'd approach this," something weird happens. You knew it a second ago. Now you're saying "um, so, I kind of, like, first I thought maybe..."

That's normal. Thinking and explaining happen differently:

• Thinking jumps around. You try things, drop them, loop back.
• Explaining has to be a straight line. The listener can only follow one step at a time.

So "what does explain your thinking mean?" It means turning your messy, jumping-around process into a clean line someone else can follow. That's a skill, and it has a structure.

The structure: Claim, Steps, Check

Say the answer first

This feels backwards to a lot of people. We want to build up to the answer like a mystery. But listeners get lost without knowing where you're heading.

Compare these two explanations for the series 2, 6, 14, 26, ?

Build-up version: "So I looked at the numbers and I noticed they were going up, and then I thought maybe it's doubling, but it wasn't, so then I tried..."

Answer-first version: "The next number is 42. The gaps are 4, 8, 12, so the next gap is 16, and 26 plus 16 is 42."

The second one is shorter and clearer, and if you make a mistake, the listener can spot exactly where.

Why it works

Saying the answer first gives your listener a hook. Every step after that is a reason for the answer, not a wandering path. It also forces you to commit, which stops you rambling while you figure it out.

Number your steps

Once you've said your claim, give your reasons as numbered steps. Out loud, that sounds like "first, second, third." On paper, it's an actual list.

Rules for good steps

1. One idea per step. If a step has "and" in the middle, it might be two steps.
2. Keep them in order. Each step should follow from the one before.
3. Don't skip "obvious" steps. What's obvious to you isn't obvious to your listener. Missing steps are the most common reason explanations fail.
4. Use linking words. "So," "because," "which means," "that's why." They show how steps connect.

How to think out loud without rambling

If you're explaining live and haven't finished thinking, say so: "Let me think this through. First, I know X. That means Y." Narrating as you go is fine. The trick is narrating in steps, not in fog.

Show how you checked

This is the part people skip, and it's the part that makes an explanation convincing. How do you know you're right?

Ways to check:

• Plug it back in. In math, put your answer back into the problem.
• Estimate. Does the size of the answer make sense?
• Test an example. In an argument, give one real case that fits your claim.
• Try the opposite. "If my answer were wrong, we'd expect to see..., and we don't."

A check turns "I think" into "I'm confident, and here's why." That's what justify your thinking really means.

Here's the catch with practising this alone: you can't easily tell whether your explanation was clear, because it always makes sense to you. IQ Tester's 16 questions spot whether putting reasoning into words is one of your weak spots, and if it is, you get daily drills built around it, like "Name the rule out loud." Find my weak spots

Examples: maths, essays, interviews

Here's the same structure in three very different settings.

How to explain your thinking in math

Problem: A jacket costs $80 and is 25% off. What's the sale price?

• Claim: "The sale price is $60."
• Steps: "First, 25% is a quarter. A quarter of 80 is 20. So I subtract 20 from 80."
• Check: "$60 is three quarters of $80, and 75% off would be much less, so it makes sense."

Explaining your thinking in an essay

Prompt: Was the character brave?

• Claim: "Maya was brave, but not reckless."
• Steps: "First, she admits she's afraid in chapter 3. Second, she goes back for her brother anyway. Third, she makes a plan before she does it."
• Check: "A reckless character wouldn't make a plan or admit fear, so 'brave, not reckless' fits better than 'fearless.'"

How to explain your thought process in an interview

Question: "How would you figure out how many pizzas to order for a school event?"

• Claim: "I'd estimate around 25 pizzas for 100 students, then adjust."
• Steps: "First, I'd get the head count. Second, I'd assume about two to three slices each. Third, with 8 slices per pizza, 100 students at 2 slices is 200 slices, so 25 pizzas."
• Check: "I'd sanity-check with whoever ran the last event, and order a couple extra since running out is worse than leftovers."

Interviewers mostly care about the structure, not the exact number. Claim, steps and check show them you think clearly.

Practise out loud

Reading about this helps a little. Saying it helps a lot. Here's how to improve your thought process and how you explain it, in five minutes a day.

1. Pick one problem. A homework question, a puzzle, or a "why" question like "why do leaves change colour?"
2. Set a one-minute timer.
3. Say claim, steps, check out loud. Actually out loud, not in your head.
4. Record it on your phone once or twice a week and listen back. You'll hear the skipped steps immediately.
5. Do it again shorter. Can you explain it in 30 seconds?

Turn clear thinking into clear words

Now you know how to explain your thought process: claim, steps, check. In the next two minutes, IQ Tester's 16 questions tell you whether putting reasoning into words is really where you slip, or whether it's something like working memory or logic chains, and you start getting one tip and one ten-minute drill a day aimed at it.

FAQ

What does "explain your thinking" mean on a test?

It means showing how you got your answer, not just the answer. Give your answer, the steps you took in order, and how you know it's right. Teachers want to see your reasoning, so they can give credit even if a small calculation slips.

How do I explain my thinking in math?

Start with your answer, then list each step with a short reason ("I divided by 4 because 25% is a quarter"), then check by plugging your answer back in or estimating. Short numbered steps beat one long paragraph.

How do you explain your thought process in an interview?

Say your approach or answer first, walk through your steps with "first, second, third," and end with how you'd check or adjust. Thinking out loud is fine as long as it's in steps. Interviewers are judging how you reason, not only the final answer.

How can I explain my thoughts clearly when I get nervous?

Lean on the structure. Say "My answer is..." first, which gives you a starting point, then "First..." and so on. Practising out loud for a minute a day makes the structure automatic, so it's there when nerves hit.

How do I justify my thinking in writing?

Make a clear claim, support it with two or three pieces of evidence in order, and add one sentence explaining why the evidence proves the claim. That last sentence is the justification most people leave out.
