Haphazard means marked by lack of norm, standard, theory, plan, order, or direction.  Something that is haphazard has no basis. Haphazard criticism flies by night.  It is willy-nilly.  It is often ex post facto, opportunistic and cheap-shot. It has no basis by which to monitor, feed back, and set right in approximate real time.

if the mechanics of motors included, in a single piece, the anthropology of drivers, criticism could be no more than haphazard.[1]CWL 21, 109

And,

if the mechanics of the intrinsically cyclical, macroeconomic mechanism included, in a single piece, the anthropology of households and firms, criticism could be no more than haphazard.[2]CWL 21, 109

Criticism must be based on a sound norm or theory.  The Walrasian static analysis of academic economists is not adequate to a dynamic process.  Statistics do not constitute a theory.  The anthropology of utility and preference is not independent of human psychology. The mere reporting of statistics does not explain and provide norms.  Both static analysis and statistical reporting are haphazard.  They are not grounded in a norm, standard, theory, plan, order, or direction independent of human psychology; i.e. they are not based on an explanatory theory of the objective functional dynamics of the process called the current, purely dynamic, economic process.
