Learning guides
Studying smarter, remembering more, and the metacognitive moves that separate effort from progress.
Reading a textbook chapter so it actually sticks. Spaced repetition without the apps. Knowing when you've actually learned something versus when you just feel like you have.
Quick answers to more learning questions — each with the tool that does the heavy lifting.
Common Myths Most People Still Believe
Some "facts" everyone knows are not actually true. Here are the ones that come up most often in conversation, plus how to spot a myth before you spread it.
- Animal myths are extremely common
- Misattributed quotes are everywhere
- Health and food myths persist long after debunking
- Historical myths often distort timing or attribution
- Use The Final Word to check before you spread
⚖️ The Final Word does this for you.
How to Ask a Question When You Do Not Even Know What to Ask
The hardest learning moments are the ones where you cannot even articulate what you do not understand. Here is how to extract a useful question from that fog.
- Find the last thing you do understand
- Try to write what you think the answer might be
- Identify what would change if you understood
- Ask the question you have, even if it seems too small
- Use The Gap to formulate the question for you

How to Extract the Important Parts from a Long Lecture
Most of a lecture is not testable. Here is how to find the 20% that is — the signals professors use to flag what really matters, and how to compress two hours of talking into one page of notes.
- Listen for the four meta-phrases
- Track repetition — three times means it is on the test
- Mark the comparisons and contrasts
- Note the worked examples — those become the question
- Use a transcript tool to surface signals you missed

How to Fact-Check a News Article That Cites a Study
News articles routinely overstate what a study found. Here is how to find the original paper, compare it to the article, and tell whether you have been told the truth.
- Find the original paper, not just the press release
- Read the abstract — not the news article — to see what was actually claimed
- Check the size of the effect and the size of the claim
- Check the population the study was actually done on
- Run Research Decoder's Media Check
📄 Research Decoder does this for you.
How to Fact-Check Something You Read Online
You saw a confident claim online and you are not sure if it is true. Here is the three-minute version of fact-checking it yourself, plus when to escalate to a deeper check.
- Search the exact claim, in quotation marks
- Find the original source, not the retelling
- Check whether reputable fact-checkers have weighed in
- Check the date and the context
- Use The Final Word to do all of this in one step

- Search for the lead author plus a key term from the article
- Check the journal name in the article
- Try searching the press release the article is based on
- When the article is too vague, use the date and topic to search recent papers
- Use Research Decoder to find and decode the paper in one step
📄 Research Decoder does this for you.
How to Know If a Study Is Reliable
Most studies that get headlines should not. Here is how to tell a solid study from a weak one in about three minutes — without needing to be a statistician.
- Check the sample size and study type first
- Check whether the result has been replicated
- Look at how big the effect is, not just whether it was statistically significant
- Check who funded it and whether the framing matches the data
- Use Research Decoder for the full reliability check in one pass
📄 Research Decoder does this for you.
How to Know What Is Actually Going to Be on the Test
Professors signal what they will test. Most students miss the signals. Here are the patterns to listen for in lecture and the way to extract them from a transcript after the fact.
- The explicit phrases — write down the sentence around them

- The "students always struggle with" tell
- Worked examples are the question template
- Run the transcript through Test Prep mode for predicted questions
🧠 The Crux does this for you.

How to Politely Tell Someone They Are Wrong About a Fact
A friend, family member, or colleague says something factually wrong. Here is how to correct them without making them feel ambushed — and when to let it go.
- Decide whether the correction matters
- Default to private correction over public

How to Read a Research Paper Without a PhD
Academic papers are not written for you, but you can extract what you need from one in fifteen minutes if you read in the right order. Here is the order — and what to skip.

- Hard because of prerequisites — keep building
- Hard because abstract — find the concrete version
- Hard because conventionally badly taught — switch teachers
- Hard because the field has built-in jargon walls
