Why shouldn't a more natural process prevent Alice from doing this
experiment with the lottery? Something far more probable than winning the
million which does not let this quantum trick happen? This would be similar
to the reasoning you applied to the quantum suicide. It could be much more
probable to implant a natural doubt in quantum immortality in Alice's brain
which causes her not to carry out the lottery trick. I definitely have this
doubt. In this way one could conclude that doubts in quantum immortality
would be a consequence of quantum immortality.

Subject: Quantum Immortality - the principle of the least
If Quantum Immortality (QI) is true, then we can ask the question what
is the TYPICAL history for an "immortal". The typical history (or the
typical time/space trajectory) would be the path most of the immortals
take (and remember that in QI all of us are immortals)
For each immortal history its weight in the space of all histories
diminishes each time an improbable event takes place. Therefore,
although in QI all of us are immortals, for a typical immortal the
history will follow the principle of the least improbability. Things
will be have in the least crazy way that will still allow the immortal
Lets say an immortal decides to commit a suicide for a particular
reason. It is then much more probable for some life event to occur
that will persuade the immortal to abandon its attempt, then for the
bullet to go through the immortal's head without actually killing the
immortal. As an example, Alice decides to commit a suicide because her
boyfriend Bob left her, Bob can change his mind, call Alice etc. so
that the reason for the suicide is removed.
Therefore, for a typical immortal there will be no bulllet going
through the head, no disfigurement etc. Instead, an event will occur
which will naturally remove the need for the suicide.
In other words, immortals will not typically perceive themselves
living in the world where strange things happen. Instead, the world
will somehow make sure that immortals stay alive AND that things
behave relatively reasonably.
Let us assume that QI is true and that all of us are immortals. What
is the least improbable thing that can allow us to stay alive forever?
Life extension. With the modern progress of biology it is not
completely improbable that a technology is discovered within say next
10 years that will reverse aging. In this scenario a typical immortal
will not even tribute his immortality to QI. Instead, immortality
will be a natural consequence of life extension.
Now lets apply the principle of the least improbability to actually
Lets assume, that Alice who believes in QI wants a certain probable
event to happen, for instance win 1,000,000 in a casino. Alice then
comes to a casino with a loaded gun and promises to herself, that she
will kill herself if she does not win 1,000,000. You can even think
about a suicidal lottery machine, which will automatically kill Alice
if Alice does not win 1,000,000.
Since Alice is immortal, there are two possivle outcomes
1). Alice wins 1,000,000 and the trigger is not pulled
2). Alice does not win 1,000,000, the trigger is pulled, the bullet
goes through Alice's head without killing Alice
Now although 1) is highly improbable 2) is much much more improbable.
Due to the principle of the least improbability 1) is going to happen
for a typical immortal - meaning that Alice wins 1,000,000
If you accept that, you should accept that QI provides a way for
immortals to influence the world by doing attempted suicides.
Essentially, anything becomes possible for an immortal.
