Executive summary: In this reflective, evidence-based analysis, Bob Fischer argues that mounting scientific and philosophical evidence makes it increasingly difficult to dismiss the possibility of insect sentience and pain, urging a cautious but meaningful expansion of moral consideration to include insects.
Key points:
Fischer recounts his shift from skepticism to cautious belief in insect sentience, driven by surprising findings in pain research across species, including insects.
Experimental evidence — such as fruit flies modified with human pain receptors responding aversively to capsaicin — suggests behaviors in insects analogous to mammalian pain responses, beyond mere nociception.
Multiple lines of reasoning (evolutionary considerations, models of pain, and cross-species cognitive tests) imply that insects may have conscious, valenced experiences.
Philosophical approaches (theory-heavy, theory-neutral, and theory-light) converge on the view that insect consciousness cannot be confidently ruled out given current knowledge.
Fischer highlights the psychological biases (e.g., size, relatability) that make it hard for humans to intuitively accept insect sentience and cautions against letting these biases dictate ethical consideration.
The essay calls for supporting insect welfare research and integrating basic concern for insect well-being into practices like farming, research, and pest control, without insisting that insect welfare dominate moral priorities.
