# RE: FIN too

```I'll have another go at explaining my position (maybe I'll spot a flaw in it if I keep
examininig it long enough). Bayesian
reasoning assumes (as far as I can see) that I should treat my present observer moment
as typical. My objection to doing so is that
this assumes the result you want to prove, because if my observer moment is typical
and QTI is correct, then the likelihood of me
experiencing a moment at which my age is less than infinity is infinitesimal.```
```
This either demonstrates that (1) my present observer moment is typical and QTI is
wrong or (2) the present observer moment isn't
typical and Bayesian reasoning is inappropriate ((2) doesn't imply that QTI is
correct, of course, merely that it's compatible with
observation).

*Assuming* that QTI is correct, then the chances of you and me interacting at a
typical observer moment (for either of us) is
negligible. QTI guarantees that almost all interactions between observers will occur
at highly non-typical observer moments, because
(scary thought) for 99.9999999999999999999....% of any given person's observer
moments, the rest of the human race will be extinct.
Hence Bayesian reasoning isn't appropriate because the fact that we're communicating
with one another guarantees that at least one
of us, and with overwhelming probability both of us, is experiencing highly atypical
observer moments.

The "assumption of typicality" can't be made without first checking that you're not
dealing with a special case. To take an obvious
example, if I was to apply Bayesian reasoning to myself I would be forced to assume
that I am almost certainly a peasant of
indeterminate sex living in the third world. Or more likely a beetle... Or even more
likely a microbe (assuming microbes have
observer moments).

Which I believe isn't the case! (Even on those rare occassions when I argue with my
better half, she very rarely calls me a
microbe...)

PS - I could be a butterfly dreaming that I'm a man, I suppose...
