Accepting Mistakes

Two responses to a mistake

"Sorry, I was stupid. Right? So I can learn quickly."¹ Masayoshi Son offered that in a 2020 DealBook interview as his entire response to a bad decision, and he sorted the world around it. "There are two kinds of people when you make a mistake. One kind don't want to accept, don't want to admit that you have made a mistake, and those people make all kinds of excuses and justify the decision they made in the wrong way. The other group accepts and admits the mistake."¹ He places himself in the second: "I'm the kind of guy who would rather accept my stupidity and my ignorance and my bad decisions, so I can learn from my mistake. I don't need to justify my mistake. I accept it." The disposition turns on a choice available only at the moment of error: justify the decision, or admit it.

In Son's framing the justifier rewrites the situation until the decision looks reasonable, which protects the ego but discards the feedback the error carried and leaves the underlying model unchanged. The accepter names the outcome plainly and updates immediately. His stated reason is competitive rather than moral: slower learning compounds against you, so the social cost of saying "I was stupid" is worth paying.

Admitting without dwelling

Son pairs the admission with a time constraint, adding "I don't want to remember it again and again." The intent is to close the loop quickly rather than to ruminate, since guilt and dwelling re-center the mistake on the self rather than on the lesson. He applies the same brevity across cases he cites in the interview. On WeWork: "We made a lot of loss in the investment, billions of dollars. And that is my mistake. Okay," followed at once by "luckily we have some other hits."¹ On an early Amazon investment he passed on over a valuation gap: "I'm so stupid," with no elaboration. On missing Elon Musk: "I bang my head," again brief.

On WeWork specifically, Son does not blame the founder, the market, or execution while defending the thesis. He says "I'm part of the responsibility," and states that he still expects the founder to recover. The pattern connects to worst-case-scenario-first, which handles error before it happens, and to obsession over discipline as the temperament that keeps Son learning despite conviction-driven bets that go wrong.

What the principle does not resolve

As stated, the account rests on a single source and a single narrator describing his own disposition, which makes it hard to separate a genuine learning practice from a public posture adopted after large losses were already visible. Son offers no test for distinguishing the two, and the brevity he prizes ("I don't want to remember it") could as easily suppress a needed post-mortem as accelerate learning. The principle is a claim about the right internal response to failure, not a mechanism for guaranteeing the lesson is actually extracted.
