Erotetic Arts

A methodology for improving reasoning under uncertainty.

Erotetic Arts is a methodology for improving reasoning under uncertainty. It starts from a simple principle: the quality of your answers depends on the quality of your questions.

Most organisations invest heavily in answers — data, models, dashboards, and increasingly AI. But the assumptions embedded in the questions that produce those answers often go unexamined. When decisions fail to converge, it is frequently not because information is missing, but because the frame is wrong: an invisible premise quietly determines what can be concluded.

Erotetic Arts works at the level of presupposition: the hidden premises that shape what is even thinkable — and what would count as settling a question in practice.

The method

Engagements (and internal use) typically follow a structured inquiry process:

  1. Surface — What question are we actually asking? What are we not asking?
  2. Examine — What does the question presuppose? Which assumptions are load-bearing?
  3. Challenge — What breaks if those assumptions fail? What would count against them?
  4. Reframe — What better question emerges once the premises are explicit?

The output is not “more analysis”. It is clearer closure: explicit decision criteria, fewer disagreement loops, and a more decisive path to action.

Applications

Strategic framing

Use the methodology to stress-test strategy: expose the load-bearing assumptions before they become expensive surprises.

Decision design

Apply the method to operational and product decisions: align stakeholders on what counts as evidence, what counts as success, and which trade-offs are being accepted.

AI and technology use-cases

Where AI is involved, the same discipline becomes operational: define what the system may assume, how success is evaluated, and how failure is detected in practice.

Published basis

The underlying work is documented publicly through Assumptology (framework and papers). Erotetic Arts is the applied methodology layer: the repeatable process for turning presuppositions into usable decision criteria.

Founder

Who's behind the work

Carl-Johan Rosenberg

I’m Carl-Johan Rosenberg, founder of Erotetic Arts Ltd. I work with teams to clarify the foundations of decisions: assumptions, admissible inference, and what would count as “settling” a question in practice. This reduces disagreement loops, rework, and failures caused by unexamined premises.

My background spans finance, operations, and technology leadership in regulated contexts. The underlying method is published as Assumptology (framework and papers), and Erotetics applies it in audits, workshops, and advisory engagements.
