According to Karl Popper, we can tell good theories from poor ones by assessing their empirical content (empirischer Gehalt), which basically reflects how much information they convey concerning the world. ``The empirical content of a statement increases with its degree of falsifiability: the...

This paper introduces a new theoretic entity, a nominalist heuristic, defined as a focus on prominent numbers, indices or ratios. Abstractions used in the evaluation stage of decision making typically involve nominalist heuristics that are incompatible with expected utility theory which excludes...

In the decision-making process, there is a stage when choosers evaluate alternatives. Evaluation is complex especially when it involves the future exchange rate. In the complexity of predicting the future exchange rate, choosers may use prominent numbers and ratios. We furnish field and...

The prior paper in this sequel, Pope (2009) introduced the concept of a nominalist heuristic, defined as a focus on prominent numbers, indices or ratios. In this paper the concept is used to show three things in how scientists and practitioners analyse and evaluate to decide (conclude). First,...

Pluralism in economics appears to be a double-edged sword: we need more than one theory to grasp and explain the entire economic world, yet a plurality of possible explanations undermines the aspiration of the economic discipline to provide 'objective knowledge' in the singular of the 'one world...
