ClaimsMark Zuckerberg

“I started Facebook, I run it, and I’m responsible for what happens here.”

Mark Zuckerberg, Facebook CEO, prepared statement 9 April 2018 This is Mark Zuckerberg's prepared statement for Congress (TechCrunch)

Factual Their own work or organisation

Mark Zuckerberg started Facebook and runs it.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

True if, as of 2018-04-09, Zuckerberg was a founder of Facebook (co-founding counts as starting it) and held the post of CEO and chairman running the company. Mostly true if he co-founded it with others and runs it, since the claim does not say he was the sole founder. Mostly false if he founded it but was not then running it, or ran it but was not among its founders. False if he neither founded Facebook nor was running it at that date.

Set before the research began.

Evidence (2)

  1. E1 Shareholders won't force Zuckerberg's hand in Facebook ... CNBC · 20 March 2018

    “Founder Mark Zuckerberg has assured that won't happen.”
  2. E2 Shareholders won't force Zuckerberg's hand in Facebook ... CNBC · 20 March 2018

    “Zuckerberg himself controls nearly 60 percent of the stock.”

Reasoning

E1 calls Zuckerberg Facebook's founder, and E2 says he controls nearly 60 percent of its stock. Neither item shows that he held the post of CEO and chairman running the company as of 2018-04-09, or whether he founded it alone or with others, so the evidence does not settle the claim under the criteria.
