What we know sannolikt
Vi har Tage Danielssons klassiska monolog om sannolikhet
som gör det svårt att veta vad som är sant och inte:
Sedan har vi förre amerikanske försvarsministern och krigshets-
aren D Rumsfeld som pratade om att veta:
Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know. And if one looks throughout the history of our country and other free countries, it is the latter category that tend to be the difficult ones.[1]
Ja, vad är sant och vad kan vi veta?
Rumsfeld svarade på frågan om det verkligen fanns
massförstörelsevapen:
the absence of evidence is not evidence of absence.
Lek med ord, men en lek som kostade miljoner människor
livet.
