ABSTRACT
My views with respect to Heisenberg's so-called 'indeterminacy relations' are practically unaffected by the transition from my old frequency interpretation of probability to the propensity interpretation. (This is due to the similarity of the two interpretations when it comes to explaining the reduction of the wave packet.)
The formula,
Ax bpx ^ b
explained in section 73 and discussed in section 75 oiL.Sc.D., I still consider to be part of the formalism which we have to interpret; and I still interpret it as a scatter relation. The only change is that I should now interpret the formula as a singular probability statement, and therefore as determining the propensity of a single particle to 'scatter': it predicts that the actual statistical scattering will be observed if we repeat the experiment in question many times, each time with a single particle.
