The "extraordinary claims require extraordinary proof" heuristic is<br>reasonable when "extraordinary claims" are taken to be those with a<br>mountain of evidence supporting them. If, however, any claim that
<br>goes contrary to your expectations counts as an "extraordinary<br>claim", this becomes a recipe for just always preserving your expectations.<br>

Oh, absolutely. In this case there is mountains of evidence supporting
the idea that disease - specifically, infectious diseases of the sort
that have now been mostly eradicated in the developed world - used to
be the primary cause of death; the requirement for extraordinary proof
is for a claim that is inconsistent with this evidence, not merely for
one that goes contrary to my expectations.<br>
