name: phg-theory-building description: Use when building the conceptual apparatus that organizes a Progress in Human Geography (PiHG) review essay — the load-bearing concept that carries the argument and re-orders a literature. Sharpens the concept; it does not gather sources or run analyses (PiHG publishes no empirical work).

Theory Building (phg-theory-building)

A PiHG essay lives or dies on its organizing concept — the idea through which a scattered literature is re-read into one argument. Unlike an empirical paper, where theory frames a study, here the concept is the instrument of synthesis: it decides what counts, how the sources relate, and what the field should see differently. Build it before you draft.

When to trigger

• Moving from "there is a literature on X" to "here is the concept that re-orders X"
• A reviewer said the review is "descriptive," "a-theoretical," or "just a summary"
• Choosing between organizing the essay by the literature's own buckets vs. by your concept
• Deciding whether to import, extend, or coin a concept

Pick the conceptual move

Move	What it does	Best when
Import a concept from elsewhere	Read the literature through an outside lens it has ignored	The field is siloed and an external idea exposes a shared structure
Extend / rework an existing concept	Show the field's own concept has drifted or is under-specified, and re-specify it	A key term is doing too much or means different things to different camps
Coin / name a concept	Give a name to a pattern the field keeps hitting but has not named	Several literatures circle the same unnamed thing
Genealogize a concept	Trace and periodize how a concept changed, to intervene in its next phase	A concept has a long, contested history

Most PiHG essays do one of these well. Trying to do all four dilutes the intervention.

The load-bearing test

Your concept must do work the literature's own categories cannot. State it as: "Read through ___, these otherwise-separate literatures are revealed to be ___, which the field has missed because ___." If the essay could be reorganized under the literature's existing headings with nothing lost, the concept is decorative, not load-bearing — and the review collapses into a summary.

Make the concept portable

PiHG rewards concepts other geographers can carry to their own cases. A good organizing concept:

• Names a relation or mechanism, not just a theme ("the circuit," "scalar mismatch," "relational precarity" — not "the platform economy").
• Travels across sub-fields (economic, urban, feminist, political ecology) rather than fitting only one.
• Has scope conditions: where it illuminates and where it should break — a concept that explains everything explains nothing.

Theory across human-geography traditions

Tradition	What "theory" looks like here	The bar
Political-economic	a structural mechanism (capital, labor, rent, state)	specify the mechanism, not just "capitalism"
Post-structural / cultural	a relational or discursive concept	show what it lets the field do, not just say
Feminist / post-colonial	a critique that reworks whose knowledge counts	change practice, not only vocabulary
More-than-human / relational	a concept re-distributing agency across human/non-human	keep it analytically usable, not just gestural

Worked micro-example (illustrative)

Literature's own buckets: precarity / algorithms / resistance (three parallel conversations)
Decorative theory: "we adopt a critical lens on platform labor" (renames, organizes nothing)
Load-bearing concept: "the CIRCUIT" — control, precarity, and resistance are the same relation seen from
  different nodes of a spatial circuit; the field missed this by treating the platform as a bounded object
Portability: any labor geographer can ask where in the circuit a given effect is produced
Scope conditions: holds where labor is distributed across nodes; weaker for genuinely single-site work

Checklist

• One clear organizing concept, not a theme or a lens-in-name-only
• It reorganizes the literature (load-bearing test passed)
• It names a relation/mechanism and is portable across sub-fields
• Scope conditions stated (where it illuminates / breaks)
• The conceptual move (import / extend / coin / genealogize) is chosen and singular

Anti-patterns

• A "lens" named in the abstract that never reorganizes anything
• Organizing the essay by the literature's own headings and calling it theory
• A concept so broad it fits every case and discriminates nothing
• Coining jargon for a pattern that already has a good name
• Borrowing a non-geographic theory wholesale with no reworking for space/place

Output format

【Concept】the organizing idea in one phrase
【Move】import / extend / coin / genealogize
【Load-bearing】what it reveals that the literature's own categories cannot
【Portability】the sentence another sub-field could import
【Scope conditions】where it holds / breaks
【Next】phg-literature-positioning
