Executive Summary

The Swiss Federal Ethics Commission on Biotechnology in the Non-Human Sector (EKAH) published a report on April 9, 2026, on the role of metaphors in new plant breeding techniques. The report examines how terms such as "gene scissors" or "genome editing" shape public perception of technologies like CRISPR/Cas. The EKAH demonstrates that metaphors have different effects in technical communication and public debate: they create associations of precision and controllability, highlight certain technology aspects while pushing others into the background. The report appears against the backdrop of ongoing regulatory debates in Switzerland and the EU regarding the handling of new genetic engineering techniques.

The EKAH publication addresses a central communication problem in biotechnology regulation: while technical terms such as "gene scissors" function neutrally in scientific contexts, they transport strong visual connotations in the public sphere that shape decision-making. This is politically relevant because the Federal Council has recently submitted a consultation draft on the "Federal Act on Plants from New Breeding Technologies" and, in parallel, the EU is defining its regulatory strategy. The report thus provides a foundation for more conscious language practice in government communication—a prerequisite for fact-based citizen participation in highly controversial technologies.

Detailed Summary

The EKAH commissioned an external expert opinion from Prof. Christina Brandt (University of Jena) that examines the mechanisms by which metaphors structure scientific and societal debates. The core of the analysis focuses on the phenomenon of selective emphasis: the term "gene scissors" evokes associations of surgical precision and simplicity, while more complex aspects—such as off-target effects, long-term ecological consequences, or ethical questions of seed control—linguistically recede into the background. This is not neutral: metaphors function as cognitive filters that privilege certain interpretive frameworks.

The debate is embedded in a regulatory turning point. In Switzerland, the Federal Council is examining whether new genetic engineering techniques such as CRISPR/Cas fall under existing genetic engineering legislation or whether new rules are needed. The EU signaled in 2023 that it could regulate genome-editing plants more leniently under certain conditions than classical genetic engineering. The EKAH emphasizes that government communication carries a responsibility for transparency: when authorities use metaphors, they should consciously employ their persuasive power—not to manipulate, but to enable citizens to form independent, fact-based judgments.

Key Findings

  • Metaphors such as "gene scissors" shape public perception of new genetic engineering more strongly than neutral technical terms
  • Linguistic framing influences which aspects of a technology are perceived as relevant
  • Government communication should reflect metaphor effects to enable independent opinion formation

Critical Questions

  1. Source Validity: Is the EKAH analysis based on empirical studies of actual public reception of these metaphors, or is it theoretical deconstruction? Which population groups were examined?

  2. Conflicts of Interest: To what extent is the EKAH itself bound by metaphors in its own language practice? Does the report itself employ rhetorical strategies that contradict its own recommendations?

  3. Causality: Does the report distinguish between metaphors as a cause of skepticism toward genetic engineering versus metaphors as a symptom of pre-existing skepticism? Can metaphors change opinion, or do they merely reinforce existing attitudes?

  4. Feasibility: What concrete language guidance does the report provide to authorities and media? How can "more conscious language practice" be practically operationalized without falling into euphemism?

  5. Counter-Hypothesis: Could "more precise" language (technical details instead of metaphors) lead to even less public understanding? Does science communication necessarily require metaphors?

  6. Timing: Why does the report appear only now, while the regulatory debate is already underway? How will the publication flow into ongoing consultation processes?
