How to Fact-Check Something You Heard on a Podcast

Podcasts are a strange source. They feel personal and trustworthy, because a voice is talking directly into your ears, but they are rarely edited the way an article is. A guest can mention a number from memory, a host can repeat a claim from a newsletter, and nobody stops to add a footnote. If you plan to repeat something you heard, it is worth ten minutes of checking first.

Here is the routine I use.

1. Write the claim down exactly

Memory compresses. "About a fifth" becomes "20 percent", "might" becomes "will", and a guest's guess turns into a fact. Before you check anything, pin down what was actually said. Find the moment in the episode and write the sentence word for word, with the timestamp.

This is the part where a transcript saves the most time. Searching for a distinctive word is far faster than scrubbing an hour-long timeline, and seeing the surrounding lines tells you whether the speaker was stating something, quoting someone or speculating.

2. Separate the speaker from the claim

Ask who is making the claim and in what role. A founder describing their own company's numbers is a primary source for what the company says, not an independent source for whether it is true. A host summarising a study is a secondhand source. A guest saying "I think" is offering an opinion. Each needs a different kind of check.

3. Watch out for summaries

Many apps now offer AI summaries of episodes, and they are useful for deciding what to read. They are not the claim. Summaries compress and sometimes overstate. In my own reading I have seen an automatic summary list dramatic statements that, on a closer look, needed much more context than the summary gave them. Always go back to the transcript line, and when the stakes are high, to the audio itself.

4. Find the original source

For any number, date or study, look for where it came from:

If you cannot find any source, that is information too. Say "according to the guest" rather than stating it as fact.

5. Check the date

Podcasts age badly. An episode from two years ago can sound current because nothing in the audio says otherwise. Note the publish date of the episode and ask whether the claim could have changed since. Forecasts in particular should be quoted with the date they were made.

6. Listen to the moment once

Text loses tone. Sarcasm, a laugh or a heavy pause can flip the meaning of a sentence. Once you have the line, play the ten seconds around it. If the speaker was joking, you will hear it.

7. Quote with context

When you use the claim, include who said it, the show, the episode date and, ideally, the timestamp. Readers can then check you the same way you checked the podcast.

A quick worked example

Say a guest on a business show mentions that a product line "grew ten times last year". Step one: search the transcript for "ten times" and copy the sentence. Step two: it is the company's own executive, so this is a company claim. Step four: look for a press release or filing from that period. Step five: check whether "last year" means the year before the episode or the current year. Step six: listen, and notice whether they said "roughly" or "more than". You end up with a sentence you can publish honestly: "In an interview published in March, the executive said the product grew roughly tenfold the previous year; the company has not released audited figures."

Tools help, judgement decides

I read most episodes I need to check in the Readpodcast AI reader, which I work on: it gives me a searchable transcript with speaker names and clickable timestamps, so steps one and six take seconds instead of minutes. You can use any transcript source you trust. The habits matter more than the tool: exact words, the right speaker, the original source, the date, and one honest listen before you repeat anything.
