A logical fallacy
where the conclusion
despite strong inductive evidence
. Although they might be right
, they are probably not
and more proof
is necessary to show that they are.
Example: The last 12 times you tried that, you blew up the lab. You haven't changed anything. Yet, you insist it will work.
Kind of hard to prove it, since they're already ignoring the obvious. A clue-by-four may be required.
