Principium minimae mirationis
Principium minimae mirationis ad machinandum usori interfacierum, programmatum, et ergonomicae pertinet.

Principium affirmat quod si duo elementa interfaciei inter se contradicunt, aut sunt ambigua, effectum esse quod usori minimam mirationem facit oportet. Maxime programmor effectum qui usori programmaturae minimam mirationem facit pro effectum qui operando programmaturae pernoto est naturalis invenire conari debet.
