Karl Popper on error and precision in measurement

In physical measurements, for instance, we always care to consider the range within which there may be an error; and precision does not consist in trying to reduce this range to nothing, or in pretending that there is no such range, but rather in its explicit recognition. (p. 235)

G. Rasch on probability and prediction

Where it is a question of human beings and their actions, it appears quite hopeless to construct models which can be useful for purposes of prediction in separate cases. On the contrary, what a human being actually does seems quite haphazard, none less than radioactive emission. (p. 11)
