What are the recent advancements in building a unified theory of bounded rationality? It seems that bounded rationality models focus on explaining a particular psychological bias, in a very specific way. In particular, its seems that the state of the art consensus is that one size does not fit all. The prevalence of framing effects makes this issue very difficult, but is there any way to think of a general approach to modelling bounded rationality.
Is it regret minimization, or random choice, or rational inattention?
The term bounded rationality was introduced by Herbert Simon. He wrote


  "The term, bounded rationality, is used to designate rational choice
  that takes into account the cognitive limitations of both knowledge
  and cognitive capacity. Bounded rationality is a central theme in
  behavioral economics. It is concerned with the ways in which the
  actual decision-making process influences decisions."


This passage seems to focus only on incomplete information, limited information processing time, limited knowledge -and not on any "psychological biases" like framing effects and the like. But the passage is complemented by a last phrase


  "Theories of bounded rationality relax one or more assumptions of
  standard expected utility theory"


which suddenly opens the content of the term to anything. So "bounded rationality" has come to signify "deviations from strict rationality in any way", making it rather impossible to arrive at a general, all-encompassing, or even most-encompassing, modeling approach, that at the same time, will be specific enough so as to be operational.
