Why does Whizard give a much larger cross section than other generators?

Q:
Whizard gives a very large cross section that is orders of magnitude larger than other generators. What is going wrong?
E.g. e+e- -> gamma gamma or pp -> jj.

A:
Whizard doesn't have any default cuts. There had been default cuts in Whizard 1, which can be emulated by including
include ("default_cuts.sin")
(which provides a default moment transfer cut of 10 GeV, a minimum energy of 10 GeV of all visible particles and an invariant mass cut of 10 GeV for all pairs of visible particles in the final state.
There is no default cut like e.g. default pT and energy cuts for photons, leptons or jets. These have to be provided by the user.
