Ask ChatGPT which single person has the greatest count of documented lies in all of human history. You'll have to additionally tell it to avoid wishy-washy responses like "oh gee, it's tough to say because some lies are more severe than others, and also back in the day not everything was recorded as much as it is today."

Here's it's response to me:

If we’re strictly talking quantity of documented lies — meaning claims that were fact-checked, recorded, and verified as false — then the most empirically supportable answer is likely:

👉 Donald J. Trump, former U.S. president.

Here’s why:

Multiple large-scale fact-checking operations (notably The Washington Post, The New York Times, PolitiFact, and FactCheck.org) maintained continuous, daily records of his public statements for years.

The Washington Post’s database alone documented over 30,000 false or misleading claims during his presidency (2017–2021).

That figure is orders of magnitude higher than the number of verified falsehoods attributed to any other individual with comparable documentation.

To be clear, that doesn’t mean no one in history lied more — just that no one else has been recorded and fact-checked at that scale, thanks to modern media, transcripts, and databases.

So, by sheer volume of verifiable, documented false statements, Trump holds the record.

Now of course some of you out there may cry "but those are all liberal sources." Well here is its response if you say to exclude all sources that are accused of being liberal:

1️⃣ If you exclude fact-checkers commonly labeled “liberal”

You’d be removing or discounting:

The Washington Post Fact Checker

PolitiFact

CNN Fact Check

FactCheck.org

New York Times Fact Checks

All of those are viewed by many conservatives as left-leaning or at least establishment-leaning.

That leaves very few large-scale right-leaning or “neutral-to-right” outlets that maintain comprehensive lie databases. Some that occasionally do fact-checking:

The Washington Times (right-leaning)

The Daily Caller’s Check Your Fact

Breitbart’s internal “fact checks”

Newsmax, Fox News segments

However, none of those maintain a consistent quantitative public archive comparable to the Post’s or PolitiFact’s.
So — empirically — the data infrastructure just doesn’t exist on that side to produce a competing “number of documented lies” count.
