Now, regarding your logic there -
I have to reply, as, although you make a good argument -
what you're saying is: For instance (a) - (where (a) is Saddam) - election is rigged, and results are false.
Therefore for all (A) results are false.
Although you draw a nice parallel in the percentages, the situation is different.
Saddam is one man who stands to gain alot by rigging something, although the results may intrinsically and evidentially be false -
Thousands of athletes in one sport being tested a number of times to produce results by a series of different individuals,
is very different indeed.
Ok, that sounds plausible. So, even though there have been some positives - like, caffeine, and a case of medicines in a few samples, out of thousands upon thousands?
Also, your argument is as such -
P: No-one dopes (supposedly)
P: Doping produces positive samples
P: If an athlete is clean, they will pass a test
E: There have been no positive tests recorded
C: (Lots of) athletes are doping.
Even if Evidence (E) is wrong, how do you draw your conclusion from your argument?
You've got a leap in logic there - and I believe it's based on your assumption that athletes are doping.
Even if we said
P: Athletes have tested positive in a number of sports
P: Athletes have tested positive in XC skiing
P: Norwegian athletes have not tested positive
C: Therefore Norwegian athletes are doping.
That still doesn't follow logically. And there's an assertion and an assumption underlying your arguments.
