No it doesn't assume that. We don't install pacemakers to everyone at birth. Even if pacemaker fails 90% of the time 90% chance of death is better than a 100%

Even if pacemaker fails 90% of the time 90% chance of death is better than a 100% without it.
- jimktrains2 8y agoYou're assuming "fails" only accounts for false negatives. False positives are a thing. If there was a 90% chance of a pacemaker going off when it wasn't needed, they wouldn't be used as it'd cause nearly as meany deaths as it prevents, assuming no false negatives.
