What sets superforecasters apart (those among us who are consistently better at predicting what will happen) is not just that they’re smarter or more open-minded.
It’s their willingness to recognize that judgment can be trained and to commit, for example, to including probabilities and base rates in their thinking.
They’re also open to being measured.
I wonder how that translates to Power-Law Masters in VC, the rare investors who have generated billion-dollar outcomes more than once.

“A wealth of information creates a poverty of attention.”
— Herb Simon, 1971
Simon was writing about how organizations could cope with an abundance of information when human attention remained scarce.
His observation feels even more relevant in the age of generative AI: he was one of the founding figures of artificial intelligence.

Why do so many investors escalate commitment to a failing course of action, throwing good money after bad into startups with increasingly poor prospects?
The usual explanation is the sunk cost fallacy: they fail to recognize that the old money is gone, and that any new investment needs to be judged on its own merits.
But recent academic work suggests another explanation: persisting has its own rewards. People who stick to their commitments, even failing ones, can be viewed as more trustworthy.
In my experience, other factors also need to be taken into account:
- not wanting to recognize a loss, especially during fundraising;
- protecting a partner’s standing within the firm; or
- keeping their track record looking good when they’re up for promotion.
There’s more going on than just struggling to let go of money already invested.

Had that exact same thought when I saw the use case @OpenAI advertised for its latest model.

Oh sick, a personal assistant that *checks notes* books my hotel for me.
Hooray.
In many cases, we are asked a question about probability (“how likely is this to happen?”) but we answer a question about similarity (“how much does this look like a stereotype I have in my mind?”).
@paulg’s joke “I can be tricked by anyone who looks like Mark Zuckerberg” is a powerful way to illustrate this bias.
