Dekanting moral philosophy

Optimally Irrational • 59 implied HN points • 06 Feb 26
📖 Philosophy Game Theory
  1. Kant’s categorical imperative doesn’t follow from pure rationality because your individual choice can’t make others follow the same rule, so behaving as if everyone would comply can be irrational in strategic situations.
  2. Game theory shows morality is best understood as self‑enforcing social conventions: stable moral rules are conditional “oughts” that arise because following them serves each person’s interests given what others do.
  3. Evolved moral feelings make cooperation feel like an absolute duty, but treating those feelings as unconditional can produce worse outcomes in problems like prisoner’s dilemmas, mutual deterrence standoffs, or strategic voting.

Why You Should Trust Trust and Distrust Distrust

rational smash and grab

bad cattitude • 281 implied HN points • 12 Nov 25
🇺🇸 U.S. Politics Game Theory
  1. Trust in systems is crucial for cooperation, but when people lose that trust, they are more likely to act selfishly for immediate gain. This shift can lead society into chaos, as individuals no longer see the value in upholding agreements or waiting for long-term benefits.
  2. The concept of the prisoner's dilemma illustrates that when one person betrays trust, others feel they must do the same to protect themselves. This fear of betrayal leads to a low-trust environment where cooperation becomes impossible.
  3. In a society where people believe that they won't benefit from the future, such as young individuals doubting social security, it's rational for them to take what they can now. Without faith in a stable future, the desire to cooperate vanishes.
