Exploratory experimentation is not theory-free

Meeting 2 of 13

Drafted v0.4 · not yet held · record discussion

Central question

What makes exploration systematic when a hypothesis or even the relevant concepts are not yet stable?

Anchor and companion

• Everyone reads the selected anchor sections and the companion abstract/overview. The rotating reader presents the companion in depth.
• Pairing: Historical account / conceptual qualification. Full records and access notes: bibliography.

Anchor

Steinle, F. (1997). Entering New Fields: Exploratory Uses of Experimentation. Philosophy of Science, 64(S4), S65–S74. https://doi.org/10.1086/392587

Read Steinle’s full short paper. The original publication is 1997; later online posting is not a second publication year.

Companion

Karaca, K. (2013). The Strong and Weak Senses of Theory-Ladenness of Experimentation: Theory-Driven versus Exploratory Experiments in the History of High-Energy Particle Physics. Science in Context, 26(1), 93–136. https://doi.org/10.1017/S0269889712000300

Read Karaca’s introduction and concluding discussion. The rotating reader presents the deep-inelastic-scattering case, including the corrected footnote 58; the whole article is optional.

Required correction with the companion

Read Karaca (2013b) (pp. 665–666) with Karaca (2013a). It corrects an equation, symbols, references, and footnote 58: Bjorken’s scaling hypothesis existed in an incomplete unpublished manuscript before the DIS experiments. Its existence does not by itself establish its role in directing the experiment.

Why these readings belong together

Steinle reconstructs exploratory experimental work. Karaca distinguishes ways theory enters exploratory and theory-directed experiments. Together they resist both a hypothesis-first caricature and the opposite claim that observations are theory-free. (Steinle 1997; Karaca 2013a)

Prepare and discuss

Read the selected anchor sections and the companion abstract or overview. Bring one source passage or artifact relevant to the case; the rotating reader presents the companion in depth.

1. Which assumptions are needed to operate and interpret an instrument?
2. When does changing a representation amount to changing a concept?
3. How should an agent record an exploratory action without retroactively inventing a hypothesis?

Case exercise: scientific gain and epistemic mode

Trace one change of representation or question in the high-energy-physics case. Separate a hypothesis existing, investigators knowing it, and its guiding the experiment. Use the erratum and mark unavailable chronology unknown.

• Profiles to examine: exploration, theory.
• Record source kind and unknown chronology; distinguish documented practice, philosophical argument, association, and our proposed agent rule.
• Ask what was gained, what warrants it, which action helped, and what a comparable agent would need to demonstrate.

Shared output

One episode entry and three sentences: what changed scientifically; what evidence warrants that account; what agent action or evaluation follows. Longer worksheets are optional.

• Episode ledger · Advance profile · Claim record.

The agent

• After the meeting, say what these papers change in the unit skill, agents/skills/unit-of-inquiry/SKILL.md: a rule at a node, a new composition of units, or a planted flaw. Meeting 1’s page shows the form.
• Modes exercised here, whose “agent actions” sections the rule would enter: exploration, theory.
• Written from the texts after the papers are read in full, as for meeting 1; nothing here yet.

Optional extensions

• Klahr and Dunbar (1988): Dual Space Search During Scientific Reasoning. Cognitive Science (1988). People solving a discovery task searched two spaces, one of hypotheses and one of experiments, and some made progress by running experiments with no hypothesis at all. Experimental evidence that inquiry has more than one search mode.
• Franklin (2005): Exploratory Experiments. Philosophy of Science (2005). Extends Steinle to high-throughput biology: experiments that generate data without a hypothesis and are still disciplined. The closest philosophical treatment of what data-driven AI-for-science work actually does.
• Colaço (2018): Rethinking the role of theory in exploratory experimentation. Biology & Philosophy (2018). Argues that exploratory experiments are guided by theory in specific ways, against reading Steinle as “theory-free”. Pairs with Karaca.
