²⁶As an aside, let me mention a most amazing interplay of fear and frustration seen in the fear of frustration, arising at the moment of making decisions. A person can be afraid of choosing the wrong flavour for his ice-cream and spend an embarrasingly long time in the decision-making process. His brain may correctly predict that a frustration will happen in the future if it turns out that he does not like the flavour that much after all. Such a fear might be present surprisingly often when humans make decisions (Schwartz, 2004).
