ClaimsNassim Taleb

“I offer a protection package and it does work, but I don’t want to be associated with trading too much.”

Nassim Taleb, interviewee 2009 Nassim Nicholas Taleb (Time interview) (Time)

Factual Economics and markets

Taleb offers a protection package to clients and it works.

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.

What would count as true or false

Judge as of 2009. The claim has two parts: (a) Taleb, through his own firm or an affiliated vehicle such as Universa Investments, where he was an adviser, offered clients a tail-risk protection product in 2009; and (b) it 'works', meaning it paid off in tail events such as the 2008 crash. True: documented evidence shows the protection product was offered and that it delivered large positive returns in the 2008 crisis or a similar tail event, e.g. reported fund returns. Mostly true: both parts hold, but the product was run by an affiliated firm rather than personally by Taleb, or the performance evidence is reported rather than audited. Mixed: the product was offered, but whether it works is unproven or the evidence is mixed. Mostly false: the product was offered, but evidence shows it lost money or failed to protect in the relevant tail event, or Taleb had no meaningful connection to it. False: no such product connected to Taleb existed in 2009.

Reasoning

The evidence reports large gains for a fund in October 2008 [E1] and over 2008 [E3]. However, the only independent item [E3] does not name Universa or Taleb, and the non-independent WSJ quotes [E1, E2] do not show that Taleb was connected to that fund or offered a protection product in 2009. Part (a) of the criteria is therefore not settled.
