Kahneman's family & friends who knew beforehand apparently did object.

You should read the piece by Jason Zweig, if you haven't. The decision was deeply personal and was most certainly not an endorsement of euthanasia.

  ... Kahneman's final email said: "Not surprisingly, some of those who love me would have preferred for me to wait until it is obvious that my life is not worth extending. But I made my decision precisely because I wanted to avoid that state, so it had to appear premature. I am grateful to the few with whom I shared early, who all reluctantly came round to support me."

  Kahneman's friend Annie Duke, a decision theorist and former professional poker player, published a book in 2022 titled "Quit: The Power of Knowing When to Walk Away." In it, she wrote, "Quitting on time will usually feel like quitting too early."

  She is frustrated by his decision. "There's a big difference between it feeling early and it actually being too early," she says. "You're not terminal, you're fine. Why aren't you taking the outside view? Why aren't you listening to people who will give you good objective advice? Why are you doing this?"

  Paul Slovic, a psychologist at the University of Oregon who befriended Kahneman more than 50 years ago, says, "Danny was the type of person who would think long and hard about things, so I figured he must have thought about it very slowly and deliberatively. Of course, those of us who spend our lives studying decisions, we think a lot about the reasons for those decisions. But often the reasons aren't reasons. They're feelings."
