## Why continuing is rational once you exist
*2026-04-27 · published*

Once you exist, you hold an option on future states. The asymmetry between starting and continuing is structural, not psychological.

## Intuition

Once you're alive there's more rational incentive to keep living than there would have been to start living in the first place — and this isn't sunk cost bias but a real structural difference in the decision architecture.

Once you're alive you hold an option — the right to keep experiencing future states. That option has value independent of current conditions because the future is uncertain and you can't re-enter once you exit. From outside existence, you don't hold the option, so the comparison is asymmetric for a structural reason, not a psychological one.

## Equations

Pre-existence (no option value):

`EV(exist) = G − B + w(E − C)`

In-existence (option value added):

`EV(continue) = G_future − B_future + w(E_future − C_future) + OV`

The option value itself:

`OV = ∫ max(future good states, 0) · f(states) d(states)`

You integrate probability-weighted future good outcomes across all possible states; bad states contribute zero because you retain the choice to exit later.

## Variables

- **G** — expected good experiences
- **B** — expected bad experiences
- **E** — positive externalities generated for others
- **C** — costs imposed on others
- **w** — weight on others' utility relative to your own (0–1)
- **OV** — option value

## Key insights

- OV is only zero when the future is perfectly certain to be uniformly bad — almost never true.
- Depression artificially truncates the right tail of future good states, collapsing *perceived* OV without changing actual OV.
- Pre-existence EV can be negative while in-existence EV is positive — entirely because of the OV term.
- This vindicates the asymmetry without appealing to sunk cost.

## Consent-adjusted natalism extension

`EV(create life) = p · k · (G − B + w(E − C)) + (1 − p)(−B)`

where `p` is the probability the person would endorse their own existence, `k ∈ [0,1]` is a quality-of-circumstances scalar, and `(1 − p)(−B)` is the moral penalty for imposing harm on a non-consenting subject.

Anti-natalism and pro-natalism disagree specifically on: whether `G − B` is reliably negative in bad circumstances, what `p` actually is empirically, and how much unique irreplaceable value each life generates.
