Gallery of models

A model is a representation and an abstraction that can be used in investigating and understanding how things work.

This is the definition of “model” that Greg Hill and I use in our E&S paper (in press).

Here are a few sources for this approach:

In this sense, models are not necessarily mathematical, empirical, or predictive. Rather, they are conceptual tools that may aid in developing insights, identifying questions, and guiding strategic practice. See this post on uses of scientific models.

Notes:

  • I like to pair the famous quip by Box and Draper (1987), “all models are wrong, but some are useful,” with a counterpoint by Holling et al. (2002) that mental models are “not wrong, just incomplete.” Similarly, Leonard and Clemson (1984) wrote, “Any two different perspectives (or models) about a system will reveal truths about that system that are neither entirely independent nor entirely compatible.”
  • With regard to the word “representation,” in the definition at top, “a model is a representation and an abstraction,” I’m thinking also of fictional representation or even misrepresentation. See, for example, Frigg (2010) Models and Fiction (pdf).
