Sources, Treatment and Potential Dangers
Università ``La Sapienza'' and INFN, Roma, Italia
The issue of asymmetric uncertainties resulting from
fits, nonlinear propagation and
systematic effects is
reviewed. It is shown that, in all cases,
whenever a published result is given with asymmetric uncertainties,
the value of the physical quantity of interest
is biased with respect to what would be obtained using at best
all experimental and theoretical information that contribute
to evaluate the combined uncertainty.
The probabilistic solution to the problem is provided
both in exact and in approximated forms.
