'the measure of some objective George Levy' is meaningless, 'the measure of

or decrease that. An interesting area is the categorisation of, then
distribution of classes of, thoughts.

I agree completely.
With the hypothesis that we are emulable by digital machine (COMP)
it is possible to say more, though. Indeed,
you can attach 'this thought' to (an equivalence class) of relative 
computationnal states (see http://iridia.ulb.ac.be/~marchal).
Survival to Quantum Suicide is then a particular case of survival
COMP suicide (and as I explain before physics became a branch of
psychology/computer science).

anthropic thinking

[Higgo James]

An aside for Nick Bostrom: 

I belive we must apply anthropic reasoning not to people - they don't exist
objectively - but to thoughts. 

An interesting point is that all thoughts about anthropic reasoning include
something along the lines of , 'this is a thought about anthropic
reasoning'. Why is this very current thought of yours (or observer moment,
if you like) a thought about anthropic reasoning? The SSA implies that
thoughts about anthropic reasoning make up a high proportion of all the
thoughts in the multiverse...
